• Overview

• Security Model

• Constants

• Data Structures

• Summary of DBMS_DATAPUMP Subprograms

45.1 DBMS_DATAPUMP Overview

DBMS_DATAPUMP provides the following support and functionality.

• 源数据库和目标数据库可以具有不同的硬件、操作系统、字符集、时区和版本。
  支持Oracle数据库11g或更高版本中存在的所有对象类型和数据类型。
  数据和元数据可以在数据库之间传输，而不需要使用任何中间文件。
  可以根据对象类型和对象名称移动数据库的一个子集。

• 模式名、数据文件名、表空间名和数据可以在导入时进行转换。
  可以重新启动以前中止的导出和导入作业，而不需要复制或删除原始作业中的任何数据或元数据。
  可以修改应用于导出或导入作业的资源。
  可以卸载和加载Oracle专有格式的数据。

45.2 DBMS_DATAPUMP Security Model

DBMS_DATAPUMP包的安全性是通过角色实现的。
DATAPUMP_EXP_FULL_DATABASE和DATAPUMP_IMP_FULL_DATABASE角色允许特权用户充分利用API。Data Pump API将使用这些角色来确定是否应该将特权应用程序角色分配给组成作业的进程。

• DATAPUMP_EXP_FULL_DATABASE

  The DATAPUMP_EXP_FULL_DATABASE role affects only Export operations. It allows users running these operations to do the following:

  • Perform the operation outside of the scope of their schema

  • Monitor jobs that were initiated by another user

  • Export objects (for example, TABLESPACE definitions) that unprivileged users cannot reference

  Although the SYS schema does not have the DATAPUMP_EXP_FULL_DATABASE role assigned to it, all security checks performed by Data Pump that require the DATAPUMP_EXP_FULL_DATABASE role will also grant access to the SYS schema.

• DATAPUMP_IMP_FULL_DATABASE

  The DATAPUMP_IMP_FULL_DATABASE role affects only Import and SQL_FILE operations. It allows users running these operations to do the following:

  • Perform the operation outside of the scope of their schema

  • Monitor jobs that were initiated by another user

  • Import objects (for example, DIRECTORY definitions) that unprivileged users cannot create

  Although the SYS schema does not have the DATAPUMP_IMP_FULL_DATABASE role assigned to it, all security checks performed by Data Pump that require the DATAPUMP_IMP_FULL_DATABASE role will also grant access to the SYS schema.

45.3 DBMS_DATAPUMP Constants

有几个公共常量定义为与DBMS_DATAPUMP一起使用。GET_STATUS过程。所有这些常量都定义为DBMS_DATAPUMP包的一部分。对这些常量的任何引用都必须使用DBMS_DATAPUMP作为前缀。并在其后加上下列符号:

Mask Bit Definitions

The following mask bit definitions are used for controlling the return of data through the DBMS_DATAPUMP.GET_STATUS procedure.

• KU$_STATUS_WIP CONSTANT BINARY_INTEGER := 1;

• KU$_STATUS_JOB_DESC CONSTANT BINARY_INTEGER := 2;

• KU$_STATUS_JOB_STATUS CONSTANT BINARY_INTEGER := 4;

• KU$_STATUS_JOB_ERROR CONSTANT BINARY_INTEGER := 8;

Dump File Type Definitions

The following definitions are used for identifying types of dump files returned through the DBMS_DATAPUMP.GET_STATUS procedure.

• KU$_DUMPFILE_TYPE_DISK CONSTANT BINARY_INTEGER := 0;

• KU$_DUMPFILE_TYPE_TEMPLATE CONSTANT BINARY_INTEGER := 3;

45.4 DBMS_DATAPUMP Data Structures

DBMS_DATAPUMP包定义了对象类型。本节中描述的类型在SYS模式中定义，供GET_STATUS函数使用。定义和使用这些类型的方式可能与您习惯的方式不同。请务必仔细阅读本部分。

定义用于GET_STATUS过程的类型集合是特定于版本的，并在类型名称中包含版本信息。一旦引入，这些类型将始终在Oracle数据库的未来版本中提供和支持，并且不会更改。但是，在Oracle数据库的未来版本中，可能会创建这些类型的新版本，以提供新的或不同的信息。这些类型的新版本将在类型名称中嵌入不同的版本信息。

例如，在Oracle数据库12c版本1(12.1)中，有一个sys。ku$_Status1210类型，在下一个Oracle数据库版本中，可能会有一个sys。ku美元_Status1310类型定义。这两种类型都可以与GET_STATUS过程一起使用。
已经为GET_STATUS过程中使用的每个类型定义了公共同义词。这使得使用类型变得更容易，这意味着您不必关心它们所驻留的实际类型名称或模式的更改。Oracle建议尽可能使用这些同义词。

对于每种类型，都有一个特定于版本的同义词和一个通用同义词。例如，为sys定义了特定于版本的同义词ku$_Status1210。ku美元_Status1210类型。
通用同义词总是描述该类型的最新版本。例如，在Oracle数据库12c版本1(12.1)中，一般的同义词ku$_Status被定义为ku$_Status1210。在将来的版本中，ku$_Status1310可能是sys.ku$Status1310的同义词。因为ku$_Status通用同义词总是指向最新的定义，所以它将指向ku$_Status1310而不是ku$_Status1210

选择使用特定于版本的同义词还是通用同义词对您的工作方式有很大的影响。使用特定于版本的名称可以保护您的代码不受Oracle数据库未来版本更改的影响，因为这些类型将继续存在并受到支持。然而，访问新信息将需要更改代码，以便为每个类型使用新的同义词名称。使用泛型名称意味着您总是需要类型的最新定义，并准备处理Oracle数据库不同版本中的更改。

当您使用的Oracle数据库版本发生更改时，需要重新编译通过通用同义词名称访问类型的任何C代码。

Note:

Languages other than PL/SQL must ensure that their type definitions are properly aligned with the version-specific definitions.

Data Structures — Object Types

The DBMS_DATAPUMP package defines the following kinds of OBJECT types:

• Worker Status Types

• Log Entry and Error Types

• Job Status Types

• Job Description Types

• Status Types

Worker Status Types

The worker status types describe what each worker process in a job is doing. The schema, object name, and object type of an object being processed will be provided. For workers processing user data, the partition name for a partitioned table (if any), the number of bytes processed in the partition, and the number of rows processed in the partition are also returned. Workers processing metadata provide status on the last object that was processed. No status for idle threads is returned.

The percent_done refers to the amount completed for the current data item being processed. It is not updated for metadata objects.

The worker status types are defined as follows:

CREATE TYPE sys.ku$_WorkerStatus1010 AS OBJECT
        (
                worker_number     NUMBER,       -- Worker process identifier

Log Entry and Error Types

These types provide informational and error text to attached clients and the log stream. The ku$LogLine.errorNumber type is set to NULL for informational messages but is specified for error messages. Each log entry may contain several lines of text messages.

The log entry and error types are defined as follows:

CREATE TYPE sys.ku$_LogLine1010 AS OBJECT (
               logLineNumber   NUMBER,
               errorNumber     NUMBER,

CREATE OR REPLACE PUBLIC SYNONYM ku$_LogEntry1020 FOR sys.ku$_LogEntry1010;
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogEntry FOR ku$_LogEntry1010;

Job Status Types

The job status type returns status about a job. Usually, the status concerns a running job but it could also be about a stopped job when a client attaches. It is typically requested at attach time, when the client explicitly requests status from interactive mode and every N seconds when the client has requested status periodically.

The job status types are defined as follows (percent_done applies to data only):

CREATE TYPE sys.ku$_JobStatus1010 IS OBJECT
        (
                job_name        VARCHAR2(30),           -- Name of the job

Job Description Types

The job description type holds all the environmental information about the job such as parameter settings and dump file set members. There are a couple of subordinate types required as well.

The job description types are defined as follows:

CREATE TYPE sys.ku$_JobDesc1010 IS OBJECT

Status Types

The status type is an aggregate of some the previous types defined and is the return value for the GET_STATUS call. The mask attribute indicates which types of information are being returned to the caller. It is created by a client's shadow process from information it retrieves off the status queue or directly from the master table.

For errors, the ku$_LogEntry that is returned has already had its log lines ordered for proper output. That is, the original ku$_LogEntry objects have been ordered from outermost context to innermost.

The status types are defined as follows:

45.5.1 ADD_FILE Procedure

此过程将文件添加到导出、导入或SQL_FILE操作的转储文件集，或指定SQL_FILE操作的日志文件或输出文件。

Syntax

DBMS_DATAPUMP.ADD_FILE (
   handle     IN NUMBER,
   filename   IN VARCHAR2,
   directory  IN VARCHAR2,
   filesize   IN VARCHAR2 DEFAULT NULL,
   filetype   IN NUMBER DEFAULT DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE,
   reusefile  IN NUMBER DEFAULT NULL);

Parameters

Table 45-2 ADD_FILE Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.
filename	The name of the file being added. filename must be a simple filename without any directory path information. For dump files, the filename can include a substitution variable. See the following table for a description of available substitution variables.
directory	The name of a directory object within the database that is used to locate filename. A directory must be specified.
filesize	The size of the dump file that is being added. It may be specified as the number of bytes, number of kilobytes (if followed by K), number of megabytes (if followed by M), number of gigabytes (if followed by G) or number of terabytes (if followed by T). An Export operation will write no more than the specified number of bytes to the file. Once the file is full, it will be closed. If there is insufficient space on the device to write the specified number of bytes, the Export operation will fail, but it can be restarted. If not specified, filesize will default to an unlimited size. For Import and SQL_FILE operations, filesize is ignored. The minimum value for filesize is ten times the default Data Pump block size, which is 4 kilobytes. A filesize can only be specified for dump files.
filetype	The type of the file to be added. The legal values are as follows and must be preceded by DBMS_DATAPUMP.: KU$_FILE_TYPE_DUMP_FILE (dump file for a job) KU$_FILE_TYPE_LOG_FILE (log file for a job) KU$_FILE_TYPE_SQL_FILE (output for SQL_FILE job)
reusefile	If 0, a preexisting file will cause an error. If 1, a preexisting file will be overwritten. If NULL, the default action for the file type will be applied (that is, dump files will not be overwritten). This parameter should only be non-NULL for dump files. The reusefile parameter is restricted to export jobs.

Substitution Variables

Table 45-3 Substitution Variables Available for the Filename Parameter on DBMS_DATAPUMP.ADD_FILE

Substitution Variable	Description
%U	The %U is expanded in the resulting file names into a two-character, fixed-width, incrementing integer starting at 01. For example, the dump filename of export%U would cause export01, export02, export03, and so on, to be created depending on how many files are needed to perform the export. For filenames containing the % character, the % must be represented as %% to avoid ambiguity.
%d, %D	Specifies the current day of the month from the Gregorian calendar in format DD. Note: This substitution variable cannot be used in an import file name.
%m, %M	Specifies the month in the Gregorian calendar in format MM. Note: This substitution variable cannot be used in an import file name.
%t, %T	Specifies the year, month, and day in the Gregorian calendar in this format: YYYYMMDD. Note: This substitution variable cannot be used in an import file name.
%l, %L	Specifies a system-generated unique file name. The file names can contain a substitution variable (%L), which implies that multiple files may be generated. The substitution variable is expanded in the resulting file names into a 2-digit, fixed-width, incrementing integer starting at 01 and ending at 99 which is the same as (%U). In addition, the substitution variable is expanded in the resulting file names into a 3-digit to 10-digit, variable-width, incrementing integers starting at 100 and ending at 2147483646. The width field is determined by the number of digits in the integer. For example if the current integer was 1, exp%Uaa%U.dmp would resolve to exp01aa01.dmp exp02aa02.dmp and so forth up until 99. Then, the next file name would have 3 digits substituted: exp100aa100.dmp exp101aa101.dmp and so forth up until 999 where the next file would have 4 digits substituted. The substitution will continue up to the largest number substitution allowed, which is 2147483646.
%y, %Y	Specifies the year in this format: YYYY. Note: This substitution variable cannot be used in an import file name.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_ARGVAL. An invalid value was supplied for an input parameter.

• INVALID_STATE. The job is completing, or the job is past the defining state for an import or SQL_FILE job or is past the defining state for LOG and SQL files.

• INVALID_OPERATION. A dump file was specified for a Network Import or ESTIMATE_ONLYexport operation.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• Adds files to a Data Pump job. Three types of files may be added to jobs: Dump files to contain the data that is being moved, log files to record the messages associated with an operation, and SQL files to record the output of a SQL_FILE operation. Log and SQL files will overwrite previously existing files. Dump files will never overwrite previously existing files. Instead, an error will be generated.

• Import and SQL_FILE operations require that all dump files be specified during the definition phase of the job. For Export operations, dump files can be added at any time. For example, if the user ascertains that the file space is running low during an Export, additional dump files may be added through this API. If the specified dump file already exists for an Export operation and reusefile is not set to 1, an error will be returned.

• For Export operations, the parallelism setting should be less than or equal to the number of dump files in the dump file set. If there are not enough dump files, the job will not be able to maximize parallelism to the degree specified by the SET_PARALLEL procedure.

• For Import operations, the parallelism setting should also be less than or equal to the number of dump files in the dump file set. If there are not enough dump files, the performance will not be optimal as multiple threads of execution try to access the same dump file.

• If the substitution variable (%U) is included in a filename, multiple dump files may be specified through a single call to ADD_FILE. For Export operations, the new dump files will be created as they are needed. Enough dump files will be created to allow all of the processes specified by the current SET_PARALLEL value to be active. If one of the dump files fills, it will be closed and a new dump file (with a new generated name) will be created to take its place. If multiple ADD_FILEs with substitution variables have been specified for dump files in a job, they will be used to generate dump files in a round robin fashion. For example, if expa%U, expb%U and expc%U were all specified for a job having a parallelism of 6, the initial dump files created would look like: expa01, expb01, expc01, expa02, expb02, and expc02.

• If presented with dump file specifications, expa%U, expb%U and expc%U, an Import or SQL_FILE operation will begin by attempting to open the dump files, expa01, expb01, and expc01.If the dump file containing the master table is not found in this set, the operation will expand its search for dump files by incrementing the substitution variable and looking up the new filenames (for example, expa02, expb02, and expc02). The DataPump API will keep expanding the search until it locates the dump file containing the master table. If the DataPump API determines that the dump file does not exist or is not part of the current dump set at any iteration, the DataPump API will stop incrementing the substitution variable for the dump file specification that was in error. Once the master table is found, the master table will be used to ascertain when all of dump files in the dump file set have been located.

45.5.2 ATTACH Function

This function gains access to a previously-created job.

Syntax

DBMS_DATAPUMP.ATTACH(
   job_name    IN VARCHAR2 DEFAULT NULL,
   job_owner    IN VARCHAR2 DEFAULT NULL) 
 RETURN NUMBER;

Parameters

Table 45-4 ATTACH Function Parameters

Parameter	Description
job_name	The name of the job. The default is the job name owned by the user who is specified in the job_owner parameter (assuming that user has only one job in the Defining, Executing, or Idling states).
job_owner	The user who originally started the job. If NULL, the value defaults to the owner of the current session. To specify a job owner other than yourself, you must have either the DATAPUMP_EXP_FULL_DATABASE role (for export operations) or the DATAPUMP_IMP_FULL_DATABASE role (for import and SQL_FILE operations). Being a privileged user allows you to monitor another user's job, but you cannot restart another user's job.

Return Values

An opaque handle for the job. This handle is used as input to the following procedures: ADD_FILE, DATA_FILTER, DETACH, GET_STATUS, LOG_ENTRY, METADATA_FILTER, METADATA_REMAP, METADATA_TRANSFORM, SET_PARALLEL, SET_PARAMETER,START_JOB, STOP_JOB, and WAIT_FOR_JOB.

Exceptions

• INVALID_ARGVAL. An invalid value was supplied for an input parameter.

• OBJECT_NOT_FOUND. The specified job no longer exists or the user specified a job owned by another schema, but the user did not have the DATAPUMP_EXP_FULL_DATABASE or DATAPUMP_IMP_FULL_DATABASE role.

• SUCCESS_WITH_INFO. The function succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• If the job was in the Stopped state, the job is placed into the Idling state. Once the ATTACHsucceeds, you can monitor the progress of the job or control the job. The stream of KU$_STATUS_WIP and KU$_STATUS_JOB_ERROR messages returned through the GET_STATUSprocedure will be returned to the newly attached job starting at the approximate time of the client's attachment. There will be no repeating of status and error messages that were processed before the client attached to a job.

• If you want to perform a second attach to a job, you must do so from a different session.

• If the ATTACH fails, use a null handle in a subsequent call to GET_STATUS for more information about the failure.

45.5.3 DATA_FILTER Procedures

This procedure specifies restrictions on the rows that are to be retrieved.

Syntax

DBMS_DATAPUMP.DATA_FILTER (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN NUMBER,
   table_name  IN VARCHAR2 DEFAULT NULL,
   schema_name IN VARCHAR2 DEFAULT NULL);

DBMS_DATAPUMP.DATA_FILTER(
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN VARCHAR2,
   table_name  IN VARCHAR2 DEFAULT NULL,
   schema_name IN VARCHAR2 DEFAULT NULL);

DBMS_DATAPUMP.DATA_FILTER(
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN CLOB,
   table_name  IN VARCHAR2 DEFAULT NULL,
   schema_name IN VARCHAR2 DEFAULT NULL);

Parameters

Table 45-5 DATA_FILTER Procedure Parameters

Parameter	Description
handle	The handle that is returned from the OPEN function
name	The name of the filter
value	The value of the filter
table_name	The name of the table on which the data filter is applied. If no table name is supplied, the filter applies to all tables in the job.
schema_name	The name of the schema that owns the table on which the filter is applied. If no schema name is specified, the filter applies to all schemas in the job. If you supply a schema name you must also supply a table name.

Exceptions

• INVALID_ARGVAL. There can be several reasons for this message:

  • A bad filter name is specified

  • The mode is TRANSPORTABLE, which does not support data filters

  • The specified table does not exist

  • The filter has already been set for the specified values of schema_name and table_name

• INVALID_STATE. The user called DATA_FILTER when the job was not in the Defining state.

• INCONSISTENT_ARGS. The value parameter is missing or its datatype does not match the filter name. Or a schema name was supplied, but not a table name.

• PRIVILEGE_ERROR. A schema name was supplied, but the user did not have the DATAPUMP_EXP_FULL_DATABASE or DATAPUMP_IMP_FULL_DATABASE role.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• 每个数据筛选器只能在每个表中出现一次(例如，您不能向一个表提供多个子查询筛选器)，或者在每个作业中出现一次。如果将使用相同名称的不同筛选器应用于特定的表和整个作业，则为特定表提供的筛选器参数将具有优先级。

  除了INCLUDE_ROWS过滤器之外，对于定义了嵌套表或域索引的表，不支持数据过滤器。在可传输表空间模式下执行的作业中不支持数据过滤器。

  可用的数据过滤器  in Table 45-6.

Table 45-6 Data Filters

Name	Datatype	Operations that Support Filter	Description
INCLUDE_ROWS	NUMBER	EXPORT, IMPORT	If nonzero, this filter specifies that user data for the specified table should be included in the job. The default is 1.
PARTITION_EXPR PARTITION_LIST	TEXT	EXPORT, IMPORT	Note: 在这个描述中，关于分区的信息也适用于子部分。 对于导出作业，这些筛选器指定从数据库卸载哪些分区。对于导入作业，它们指定将哪些表分区加载到数据库中。如果分区名满足指定的表达式(对于PARTITION_EXPR)，或者包含在列表中(对于PARTITION_LIST)，则将分区名包含在作业中。虽然过滤器的表达式版本提供了更多的灵活性，但是列表版本提供了对分区名的完整验证。 在分区名周围加上双引号
SAMPLE	NUMBER	EXPORT, IMPORT	对于导出作业，指定要移动的数据块的抽样百分比。此筛选器允许提取大型表的子集以用于测试。
SUBQUERY	TEXT	EXPORT, IMPORT	指定添加到表的SELECT语句末尾的子查询。如果在子查询中指定WHERE子句，则可以限制所选择的行。指定一个ORDER BY子句可以对导出中转储的行进行排序，从而在从堆组织的表迁移到索引组织的表时提高性能。

45.5.4 DATA_REMAP Procedure

This procedure specifies transformations to be applied to column data as it is exported from, or imported into, a database.

Syntax

DBMS_DATAPUMP.DATA_REMAP(
   handle          IN NUMBER,
   name            IN VARCHAR2,
   table_name      IN VARCHAR2,
   column          IN VARCHAR2,
   remap_function  IN VARCHAR2,
   schema          IN VARCHAR2 DEFAULT NULL);

Parameters

Table 45-7 DATA_REMAP Procedure Parameters

Parameter	Description
handle	The handle of the current job. The current session must have previously attached to the handle through a call to an OPEN function.
name	The name of the remap
table_name	The table containing the column to be remapped
column	The name of the column to be remapped
remap_function	The meaning of remap_function is dependent upon the value of name. See Table 45-8 for a list of possible names.
schema	The schema containing the column to be remapped. If NULL, the remapping applies to all schemas moved in the job that contain the specified table.

Exceptions

• INVALID_ARGVAL. The mode is transportable (which does not support data modifications) or it has specified that no data to be included in the job. An invalid remap name was supplied.

• INVALID_OPERATION. Data remaps are only supported for Export and Import operations.

• INVALID_STATE. The DATA_REMAP procedure was called after the job started (that is, it was not in the defining state).

• NO_SUCH_JOB. The job handle is no longer valid.

Usage Notes

• The DATA_REMAP procedure is only supported for Export and Import operations. It allows you to manipulate user data being exported or imported. The name of the remap determines the remap operation to be performed.

• For export operations, you might wish to define a data remap to obscure sensitive data such as credit card numbers from a dump file, but leave the remainder of the data so that it can be read. To accomplish this, the remapping should convert each unique source number into a distinct generated number. So that the mapping is consistent across the dump file set, the same function should be called for every column that contains the credit card number.

• For import operations, you might wish to define a data remap to reset the primary key when data is being merged into an existing table that contains colliding primary keys. A single remapping function should be provided for all columns defining or referencing the primary key to ensure that remapping is consistent.

Note:

If the called function uses package state variables, then to ensure that remapping is performed consistently across all tables, the job should be run with a SET_PARALLEL value of 1 and no restart operations should be performed.

The Data Remap functions are listed in Table 45-8.

Table 45-8 Names of Data Remap Functions

Name	Meaning of remap_function	Meaning
COLUMN_FUNCTION	String having the format: [schema.]package.function	The name parameter references a PL/SQL package function which is called to modify the data for the specified column. The function accepts a single parameter, which has the same datatype as the remapped column, and returns a value having the same datatype as the remapped column. Note that the default for the schema is the schema of the user performing the export.

45.5.5 DETACH Procedure

This procedure specifies that the user has no further interest in using the handle.

Syntax

DBMS_DATAPUMP.DETACH(
   handle  IN NUMBER);

Parameters

Table 45-9 DETACH Procedure Parameters

Parameter	Description
handle	The handle of the job. The current session must have previously attached to the handle through a call to either an OPEN or ATTACH function.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• Through this call, you specify that you have no further interest in using the handle. Resources associated with a completed job cannot be reclaimed until all users are detached from the job. An implicit detach from a handle is performed when the user's session is exited or aborted. An implicit detach from a handle is also performed upon the expiration of the timeout associated with a STOP_JOB that was applied to the job referenced by the handle. All previously allocated DBMS_DATAPUMP handles are released when an instance is restarted.

45.5.6 GET_DUMPFILE_INFO Procedure

This procedure retrieves information about a specified dump file.

Syntax

DBMS_DATAPUMP.GET_DUMPFILE_INFO(
   filename    IN VARCHAR2,
   directory   IN VARCHAR2,
   info_table  OUT ku$_dumpfile_info,
   filetype    OUT NUMBER);

Parameters

Table 45-10 GET_DUMPFILE_INFO Procedure Parameters

Parameter	Description
filename	A simple filename with no directory path information
directory	A directory object that specifies where the file can be found
info_table	A PL/SQL table for storing information about the dump file
filetype	The type of file (Data Pump dump file, original Export dump file, external tables dump file, or unknown)

Exceptions

The GET_DUMPFILE_INFO procedure is a utility routine that operates outside the context of any Data Pump job. Exceptions are handled differently for this procedure than for procedures associated in some way with a Data Pump job. A full exception stack should be available directly, without the need to call the GET_STATUS procedure to retrieve the detailed information. The exception for this procedure is as follows:

• NO_DUMPFILE_INFO. Unable to retrieve dump file information as specified.

Usage Notes

You can use the GET_DUMPFILE_INFO procedure to request information about a specific file. If the file is not recognized as any type of dump file, then a filetype of 0 (zero) is returned and the dump file info_table remains empty.

A filetype value of 1 indicates a Data Pump dump file. A filetype value of 2 indicates an original Export dump file. A filetype value of 3 indicates an external tables dump file. In all cases, the dump file info_table will be populated with information retrieved from the dump file header. Rows of this table consist of item code and value pairs, where the item code indicates the type of information and the value column is a VARCHAR2 containing the actual data (converted to a string in some cases). The table is defined as follows:

CREATE TYPE sys.ku$_dumpfile_item IS OBJECT (
                item_code       NUMBER,           -- Identifies header item
                value           VARCHAR2(2048)    -- Text string value)/
 
GRANT EXECUTE ON sys.ku$_dumpfile_item TO PUBLIC; 
CREATE OR REPLACE PUBLIC SYNONYM ku$_dumpfile_item FOR sys.ku$_dumpfile_item;
 
CREATE TYPE sys.ku$_dumpfile_info AS TABLE OF sys.ku$_dumpfile_item/
 
GRANT EXECUTE ON sys.ku$_dumpfile_info TO PUBLIC; 
CREATE OR REPLACE PUBLIC SYNONYM ku$_dumpfile_info FOR sys.ku$_dumpfile_info;
 

The item codes, which can easily be extended to provide more information as needed, are currently defined as shown in Table 45-11 (prepended with the package name, DBMS_DATAPUMP.). Assume the following with regard to these item codes:

• Unless otherwise stated, all item codes may be returned only for Oracle Data Pump and external tables dump files (filetypes 1 and 3).

• Unless otherwise stated, all item codes have been available since Oracle Database 10g Release 2 (10.2).

45.5.7 GET_STATUS Procedure

This procedure monitors the status of a job or waits for the completion of a job.

Syntax

DBMS_DATAPUMP.GET_STATUS(
   handle    IN NUMBER,
   mask      IN BINARY_INTEGER,
   timeout   IN NUMBER DEFAULT NULL,
   job_state OUT VARCHAR2,
   status    OUT ku$_Status);

Parameters

Table 45-12 GET_STATUS Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. A null handle can be used to retrieve error information after OPEN and ATTACH failures.
mask	A bit mask that indicates which of four types of information to return: KU$_STATUS_WIP KU$_STATUS_JOB_DESC KU$_STATUS_JOB_STATUS KU$_STATUS_JOB_ERROR Each status has a numerical value. You can request multiple types of information by adding together different combinations of values.
timeout	Maximum number of seconds to wait before returning to the user. A value of 0 requests an immediate return. A value of -1 requests an infinite wait. If KU$_STATUS_WIP or KU$_STATUS_JOB_ERROR information is requested and becomes available during the timeout period, then the procedure returns before the timeout period is over.
job_state	Current state of the job. If only the job state is needed, it is much more efficient to use this parameter than to retrieve the full ku$_Status structure.
status	A ku$_Status is returned. The ku$_Status mask indicates what kind of information is included. This could be none if only KU$_STATUS_WIP or KU$_STATUS_JOB_ERRORinformation is requested and the timeout period expires.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_VALUE. The mask or timeout contains an illegal value.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

The GET_STATUS procedure is used to monitor the progress of an ongoing job and to receive error notification. You can request various type of information using the mask parameter. The KU$_STATUS_JOB_DESC and KU$_STATUS_JOB_STATUS values are classified as synchronous information because the information resides in the master table. The KU$_STATUS_WIP and KU$_STATUS_JOB_ERROR values are classified as asynchronous because the messages that embody these types of information can be generated at any time by various layers in the Data Pump architecture.

• If synchronous information only is requested, the interface will ignore the timeout parameter and simply return the requested information.

• If asynchronous information is requested, the interface will wait a maximum of timeout seconds before returning to the client. If a message of the requested asynchronous information type is received, the call will complete prior to timeout seconds. If synchronous information was also requested, it will be returned whenever the procedure returns.

• If the job_state returned by GET_STATUS does not indicate a terminating job, it is possible that the job could still terminate before the next call to GET_STATUS. This would result in an INVALID_HANDLE exception. Alternatively, the job could terminate during the call to GET_STATUS, which would result in a NO_SUCH_JOB exception. Callers should be prepared to handle these cases.

Error Handling

There are two types of error scenarios that need to be handled using the GET_STATUS procedure:

• Errors resulting from other procedure calls: For example, the SET_PARAMETER procedure may produce an INCONSISTENT_ARGS exception. The client should immediately call GET_STATUSwith mask=8 (errors) and timeout=0. The returned ku$_Status.error will contain a ku$_LogEntry that describes the inconsistency in more detail.

• Errors resulting from events asynchronous to the client(s): An example might be Table alreadyexists when trying to create a table. The ku$_Status.error will contain a ku$_LogEntrywith all error lines (from all processing layers that added context about the error) properly ordered.

After a job has begun, a client's main processing loop will typically consist of a call to GET_STATUSwith an infinite timeout (-1) "listening" for KU$_STATUS_WIP and KU$_STATUS_JOB_ERRORmessages. If status was requested, then JOB_STATUS information will also be in the request.

When the ku$_Status is interpreted, the following guidelines should be used:

• ku$_Status.ku$_JobStatus.percent_done refers only to the amount of data that has been processed in a job. Metadata is not considered in the calculation. It is determined using the following formulas:

  • EXPORT or network IMPORT--(bytes_processed/estimated_bytes) * 100

  • IMPORT--(bytes_processed/total_expected_bytes) * 100

  • SQL_FILE or estimate-only EXPORT--0.00 if not done or 100.00 if done

  The effects of the QUERY and PARTITION_EXPR data filters are not considered in computing percent_done.

  It is expected that the status returned will be transformed by the caller into more user-friendly status. For example, when percent done is not zero, an estimate of completion time could be produced using the following formula:

  ((SYSDATE - start time) / ku$_Status.ku$_JobStatus.percent_done) * 100
  

• The caller should not use ku$_Status.ku$_JobStatus.percent_done for determining whether the job has completed. Instead, the caller should only rely on the state of the job as found in job_state.

45.5.8 LOG_ENTRY Procedure

This procedure inserts a message into the log file.

Syntax

DBMS_DATAPUMP.LOG_ENTRY(
   handle         IN NUMBER,
   message        IN VARCHAR2
   log_file_only  IN NUMBER DEFAULT 0);

Parameters

Table 45-13 LOG_ENTRY Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.
message	A text line to be added to the log file
log_file_only	Specified text should be written only to the log file. It should not be returned in GET_STATUS work-in-progress (KU$_STATUS_WIP) messages.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

The message is added to the log file. If log_file_only is zero (the default), the message is also broadcast as a KU$_STATUS_WIP message through the GET_STATUS procedure to all users attached to the job.

The LOG_ENTRY procedure allows applications to tailor the log stream to match the abstractions provided by the application. For example, the command-line interface supports INCLUDE and EXCLUDE parameters defined by the user. Identifying these values as calls to the underlying METADATA_FILTER procedure would be confusing to users. Instead, the command-line interface can enter text into the log describing the settings for the INCLUDE and EXCLUDE parameters.

Lines entered in the log stream from LOG_ENTRY are prefixed by the string, ";;; "

45.5.9 METADATA_FILTER Procedure

This procedure provides filters that allow you to restrict the items that are included in a job.

Syntax

DBMS_DATAPUMP.METADATA_FILTER(
   handle       IN NUMBER,
   name         IN VARCHAR2,
   value        IN VARCHAR2,
   object_path  IN VARCHAR2 DEFAULT NULL);

DBMS_DATAPUMP.METADATA_FILTER(
   handle       IN NUMBER,
   name         IN VARCHAR2,
   value        IN CLOB,
   object_path  IN VARCHAR2 DEFAULT NULL);

Parameters

Table 45-14 METADATA_FILTER Procedure Parameters

Parameter	Description
handle	The handle returned from the OPEN function
name	The name of the filter. See Table 45-15 for descriptions of the available filters.
value	The value of the filter
object_path	The object path to which the filter applies. If the default is used, the filter applies to all applicable objects. Lists of the object paths supported for each mode are contained in the catalog views for DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, and TABLE_EXPORT_OBJECTS. (Note that the TABLE_EXPORT_OBJECTS view is applicable to both Table and Tablespace mode because their object paths are the same.) For an import operation, object paths reference the mode used to create the dump file rather than the mode being used for the import.

Table 45-15 describes the name, the object type, and the meaning of the filters available with the METADATA_FILTER procedure. The datatype for all the filters is a text expression. All operations support all filters.

Table 45-15 Filters Provided by METADATA_FILTER Procedure

Name	Object Type	Meaning
NAME_EXPR NAME_LIST	Named objects	Defines which object names are included in the job. You use the object type parameter to limit the filter to a particular object type. For Table mode, identifies which tables are to be processed.
SCHEMA_EXPR SCHEMA_LIST	Schema objects	Restricts the job to objects whose owning schema name is satisfied by the expression. For Table mode, only a single SCHEMA_EXPR filter is supported. If specified, it must only specify a single schema (for example, 'IN (''SCOTT'')'). For Schema mode, identifies which users are to be processed.
TABLESPACE_EXPR TABLESPACE_LIST	TABLE, CLUSTER, INDEX, ROLLBACK_SEGMENT	Restricts the job to objects stored in a tablespace whose name is satisfied by the expression. For Tablespace mode, identifies which tablespaces are to be processed. If a partition of an object is stored in the tablespace, the entire object is added to the job. For Transportable mode, identifies which tablespaces are to be processed. If a table has a single partition in the tablespace set, all partitions must be in the tablespace set. An index is not included within the tablespace set unless all of its partitions are in the tablespace set. A domain index is not included in the tablespace set unless all of its secondary objects are included in the tablespace set.
INCLUDE_PATH_EXPR INCLUDE_PATH_LIST EXCLUDE_PATH_EXPR EXCLUDE_PATH_LIST	All	Defines which object paths are included in, or excluded from, the job. You use these filters to select only certain object types from the database or dump file set. Objects of paths satisfying the condition are included (INCLUDE_PATH_*) or excluded (EXCLUDE_PATH_*) from the operation. The object_path parameter is not supported for these filters.
EXCLUDE_TABLES	TABLE_EXPORT	Specifies that no tables are to be exported.
VIEWS_AS_TABLES	TABLE_EXPORT	A comma-separated list of views to be exported as tables: [schema_name.]view_name[:table_name] The filter can be called multiple times with multiple values and all values get added to a list. All views on the list are exported as tables.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_ARGVAL. This exception can indicate any of the following conditions:

  • An object_path was specified for an INCLUDE_PATH_EXPR or EXCLUDE_PATH_EXPRfilter.

  • The specified object_path is not supported for the current mode.

  • The SCHEMA_EXPR filter specified multiple schemas for a Table mode job.

• INVALID_STATE. The user called the METADATA_FILTER procedure after the job left the defining state.

• INCONSISTENT_ARGS. The filter value is of the wrong datatype or is missing.

• SUCCESS_WITH_INFO. The procedure succeeded but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• Metadata filters identify a set of objects to be included or excluded from a Data Pump operation. Except for EXCLUDE_PATH_EXPR and INCLUDE_PATH_EXPR, dependent objects of an identified object will be processed along with the identified object. For example, if an index is identified for inclusion by a filter, grants upon that index will also be included by the filter. Likewise, if a table is excluded by a filter, then indexes, constraints, grants and triggers upon the table will also be excluded by the filter.

• Two versions of each filter are supported: SQL expression and List. The SQL expression version of the filters offer maximum flexibility for identifying objects (for example the use of LIKE to support use of wild cards). The names of the expression filters are as follows:

  • NAME_EXPR

  • SCHEMA_EXPR

  • TABLESPACE_EXPR

  • INCLUDE_PATH_EXPR

  • EXCLUDE_PATH_EXPR

  The list version of the filters allow maximum validation of the filter. An error will be reported if one of the elements in the filter is not found within the source database (for Export and network-based jobs) or is not found within the dump file (for file-based Import and SQLFILE jobs). The names of the list filters are as follows:

  • NAME_LIST

  • SCHEMA_LIST

  • TABLESPACE_LIST

  • INCLUDE_PATH_LIST

  • EXCLUDE_PATH_LIST

• Filters allow a user to restrict the items that are included in a job. For example, a user could request a full export, but without Package Specifications or Package Bodies.

• If multiple filters are specified for a object type, they are implicitly 'ANDed' together (that is, objects participating in the job must pass all of the filters applied to their object types).

• The same filter name can be specified multiple times within a job. For example, specifying NAME_EXPR as '!=''EMP''' and NAME_EXPR as '!=''DEPT''' on a Table mode export would produce a file set containing all of the tables except for EMP and DEPT.

45.5.10 METADATA_REMAP Procedure

This procedure specifies a remapping to be applied to objects as they are processed in the specified job.

Syntax

DBMS_DATAPUMP.METADATA_REMAP (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   old_value   IN VARCHAR2,
   value       IN VARCHAR2,
   object_type IN VARCHAR2 DEFAULT NULL);

Parameters

Table 45-16 METADATA_REMAP Procedure Parameters

Parameter	Description
handle	The handle for the current job. The current session must have previously attached to the handle through a call to the OPEN function.
name	The name of the remap. See Table 45-17 for descriptions of the available remaps.
old_value	Specifies which value in the dump file set should be reset to value
value	The value of the parameter for the remap. This signifies the new value that old_valueshould be translated into.
object_type	Designates the object type to which the remap applies. The list of object types supported for each mode are contained in the DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, TABLE_EXPORT_OBJECTS, and TABLESPACE_EXPORT_OBJECTS catalog views. By default, the remap applies to all applicable objects within the job. The object_typeparameter allows a caller to specify different parameters for different object types within a job. Remaps that explicitly specify an object type override remaps that apply to all object types.

Table 45-17 describes the remaps provided by the METADATA_REMAP procedure.

Table 45-17 Remaps Provided by the METADATA_REMAP Procedure

Name	Datatype	Object Type	Meaning
REMAP_SCHEMA	TEXT	Schema objects	Any schema object in the job that matches the object_typeparameter and was located in the old_value schema will be moved to the value schema. Privileged users can perform unrestricted schema remaps. Nonprivileged users can perform schema remaps only if their schema is the target schema of the remap. For example, SCOTT can remap his BLAKE's objects to SCOTT, but SCOTT cannot remap SCOTT'sobjects to BLAKE.
REMAP_TABLESPACE	TEXT	TABLE, INDEX, ROLLBACK_SEGMENT, MATERIALIZED_VIEW, MATERIALIZED_VIEW_LOG,TABLE_SPACE	Any storage segment in the job that matches the object_typeparameter and was located in the old_value tablespace will be relocated to the value tablespace.
REMAP_DATAFILE	TEXT	LIBRARY, TABLESPACE, DIRECTORY	If old_value and value are both full file specifications, then any data file reference in the job that matches the object_typeparameter and that referenced the old_value data file will be redefined to use the value data file. If old_value and value are both directory paths, then any data file reference whose object path matches old_value will have its path substituted with value.
REMAP_TABLE	TEXT	TABLE	Any reference to a table in the job that matches the old_value table name will be replaced with the value table name. The old_valueparameter may refer to a partition such as employees.low. This allows names for tables constructed the by PARTITION_OPTIONS=DEPARTITION parameter to be specified by the user.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_ARGVAL. This message can indicate any of the following:

  • The job's mode does not include the specified object_type.

  • The remap has already been specified for the specified old_value and object_type.

• INVALID_OPERATION. Remaps are only supported for SQL_FILE and Import operations. The job's operation was Export, which does not support the use of metadata remaps.

• INVALID_STATE. The user called METADATA_REMAP after the job had started (that is, the job was not in the defining state).

• INCONSISTENT_ARGS. There was no value supplied or it was of the wrong datatype for the remap.

• PRIVILEGE_ERROR. A nonprivileged user attempted to do a REMAP_SCHEMA to a different user's schema or a REMAP_DATAFILE.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• The METADATA_REMAP procedure is only supported for Import and SQL_FILE operations. It enables you to apply commonly desired, predefined remappings to the definition of objects as part of the transfer. If you need remaps that are not supported within this procedure, you should do a preliminary SQL_FILE operation to produce a SQL script corresponding to the dump file set. By editing the DDL directly and then executing it, you can produce any remappings that you need.

• Transforms for the DataPump API are a subset of the remaps implemented by the DBMS_METADATA.SET_TRANSFORM_PARAMETER API. Multiple remaps can be defined for a single job. However, each remap defined must be unique according its parameters. That is, two remaps cannot specify conflicting or redundant remaps.

45.5.11 METADATA_TRANSFORM Procedure

This procedure specifies transformations to be applied to objects as they are processed in the specified job.

Syntax

DBMS_DATAPUMP.METADATA_TRANSFORM (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN VARCHAR2,
   object_type IN VARCHAR2 DEFAULT NULL);

DBMS_DATAPUMP.METADATA_TRANSFORM (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN NUMBER,
   object_type IN VARCHAR2 DEFAULT NULL);

Parameters

Table 45-18 METADATA_TRANSFORM Procedure Parameters

Parameter	Description
handle	The handle for the current job. The current session must have previously attached to the handle through a call to the OPEN function.
name	The name of the transformation. See Table 45-19 for descriptions of the available transforms.
value	The value of the parameter for the transform
object_type	Designates the object type to which the transform applies. The list of object types supported for each mode are contained in the DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, TABLE_EXPORT_OBJECTS, and TABLESPACE_EXPORT_OBJECTS catalog views. By default, the transform applies to all applicable objects within the job. The object_typeparameter allows a caller to specify different transform parameters for different object types within a job. Transforms that explicitly specify an object type override transforms that apply to all object types.

Table 45-19 describes the transforms provided by the METADATA_TRANSFORM procedure.

Table 45-19 Transforms Provided by the METADATA_TRANFORM Procedure

Name	Datatype	Object Type	Meaning
DISABLE_ARCHIVE_LOGGING	NUMBER	TABLE INDEX	Specifies whether to disable archive logging for specified object types during import. A value of zero (FALSE) is the default. It specifies that archive logging will take place. This is the default behavior if this transform parameter is not specified. A non-zero (TRUE) value disables archive logging for the specified object types before data is loaded during import. If no object type is specified, then archive logging is disabled for both TABLE and INDEX object types. All other object types processed during data pump import are logged. Note: If the database is in FORCE LOGGING mode, then the DISABLE_ARCHIVE_LOGGING transform does not disable logging when indexes and tables are created.
INMEMORY	NUMBER	TABLE TABLESPACE MATERIALIZEDVIEWS	The INMEMORY transform is related to the In-Memory Column Store (IM column store), an optional area in the SGA that stores whole tables, table partitions, and individual columns in a compressed columnar format. If a non-zero value (TRUE) is specified on import, then Data Pump generates an IM clause that preserves the IM setting those objects had at export time. This is the default. If a value of zero (FALSE) is specified on import, then Data Pump does not include an IM clause for any objects. Note: The INMEMORY transform is available only in Oracle Database 12c Release 1 (12.1.0.2) or higher.
INMEMORY_CLAUSE	TEXT	TABLE TABLESPACE MATERIALIZED VIEWS	The INMEMORY_CLAUSE transform is related to the In-Memory Column Store (IM column store), an optional area in the SGA that stores whole tables, table partitions, and individual columns in a compressed columnar format. When you specify this transform, Data Pump uses the contents of the string as the IM clause for all objects being imported that have an IM clause in their DDL. This transform is useful when you want to override the IM clause for an object in the dump file. Note: The INMEMORY_CLAUSE transform is available only in Oracle Database 12c Release (12.1.0.2) or higher.
LOB_STORAGE	TEXT	TABLE	Specifies the storage type to use for LOB segments. The options are as follows: SECUREFILE - LOB storage is returned as SECUREFILE BASICFILE - LOB storage is returned as BASICFILE DEFAULT - The keyword (SECUREFILE or BASICFILE) is omitted in the LOB STORE AS clause. NO_CHANGE - LOB segments are created with the same storage they had in the source database. This is the default. Specifying this transform changes the LOB storage for all tables in the job, including tables that provide storage for materialized views.
OID	NUMBER	TYPE TABLE	If zero, inhibits the assignment of the exported OID during type or table creation. Instead, a new OID will be assigned. Use of this transform on Object Tables will cause breakage in REF columns that point to the table. Defaults to 1.
PCTSPACE	NUMBER	TABLE INDEX TABLESPACE	Specifies a percentage multiplier used to alter extent allocations and data file sizes. Used to shrink large tablespaces for testing purposes. Defaults to 100.
SEGMENT_ATTRIBUTES	NUMBER	TABLE, INDEX	If nonzero (TRUE), emit storage segment parameters. Defaults to 1.
SEGMENT_CREATION	NUMBER	TABLE	If nonzero (TRUE), the SQL SEGMENT CREATIONclause is added to the CREATE TABLE statement. That is, the CREATE TABLE statement will explicitly say either SEGMENT CREATION DEFERRED or SEGMENT CREATION IMMEDIATE. If the value is FALSE, then the SEGMENT CREATION clause is omitted from the CREATE TABLE statement. Set this parameter to FALSE to use the default segment creation attributes for the table(s) being loaded. Defaults to nonzero (TRUE).
STORAGE	NUMBER	TABLE	If nonzero (TRUE), emit storage clause. (Ignored if SEGMENT_ATTRIBUTES is zero.) Defaults to nonzero (TRUE).
TABLE_COMPRESSION_CLAUSE	TEXT	TABLE	Specifies a table compression clause (for example, COMPRESS BASIC) to use when the table is created. Specify NONE to omit the table compression clause. The table will have the default compression for the tablespace. Specifying this transform changes the compression type for all tables in the job, including tables that provide storage for materialized views.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_ARGVAL. This message can indicate any of the following:

  • The mode is transportable, which doesn't support transforms.

  • The job's mode does not include the specified object_type.

  • The transform has already been specified for the specified value and object_type.

• INVALID_OPERATION. Transforms are only supported for SQL_FILE and Import operations. The job's operation was Export which does not support the use of metadata transforms.

• INVALID_STATE. The user called METADATA_TRANSFORM after the job had started (that is, the job was not in the defining state).

• INCONSISTENT_ARGS. There was no value supplied or it was of the wrong datatype for the transform.

• PRIVILEGE_ERROR. A nonprivileged user attempted to do a REMAP_SCHEMA to a different user's schema or a REMAP_DATAFILE.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• The METADATA_TRANSFORM procedure is only supported for Import and SQL_FILE operations. It enables you to apply commonly desired, predefined transformations to the definition of objects as part of the transfer. If you need transforms that are not supported within this procedure, you should do a preliminary SQL_FILE operation to produce a SQL script corresponding to the dump file set. By editing the DDL directly and then executing it, you can produce any transformations that you need.

• Transforms for the DataPump API are a subset of the transforms implemented by the DBMS_METADATA.SET_TRANSFORM_PARAMETER API. Multiple transforms can be defined for a single job. However, each transform defined must be unique according its parameters. That is, two transforms cannot specify conflicting or redundant transformations.

45.5.12 OPEN Function

This function is used to declare a new job using the Data Pump API.

The handle that is returned is used as a parameter for calls to all other procedures (but not to the ATTACH function).

Syntax

DBMS_DATAPUMP.OPEN (
   operation    IN VARCHAR2,
   job_mode         IN VARCHAR2,
   remote_link  IN VARCHAR2 DEFAULT NULL,
   job_name     IN VARCHAR2 DEFAULT NULL,
   version      IN VARCHAR2 DEFAULT 'COMPATIBLE')
 RETURN NUMBER;

Parameters

Table 45-20 OPEN Function Parameters

Parameter	Meaning
operation	The type of operation to be performed. Table 45-21 contains descriptions of valid operation types.
job_mode	The scope of the operation to be performed. Table 45-22 contains descriptions of valid modes. Specifying NULL generates an error.
remote_link	If the value of this parameter is non-null, it provides the name of a database link to the remote database that will be the source of data and metadata for the current job.
job_name	The name of the job. The name is limited to 128 characters; it will be truncated if more than 128 characters are used. It may consist of printable characters and spaces. It is implicitly qualified by the schema of the user executing the OPEN function and must be unique to that schema (that is, there cannot be other Data Pump jobs using the same name). The name is used to identify the job both within the API and with other database components such as identifying the job in the DBA_RESUMABLE view if the job becomes suspended through lack of resources. If no name is supplied, a system generated name will be provided for the job in the following format: "SYS___%N". The default job name is formed where %N expands to a two-digit incrementing integer starting at '01' (for example, "SYS_IMPORT_FULL_03"). The name supplied for the job will also be used to name the master table and other resources associated with the job.
version	The version of database objects to be extracted. This option is only valid for Export, network Import, and SQL_FILE operations. Database objects or attributes that are incompatible with the version will not be extracted. Legal values for this parameter are as follows: COMPATIBLE - (default) the version of the metadata corresponds to the database compatibility level and the compatibility release level for feature (as given in the V$COMPATIBILITY view). Database compatibility must be set to 9.2 or higher. LATEST - the version of the metadata corresponds to the database version. A specific database version, for example, '11.0.0'. Specify a value of 12 to allow all existing database features, components, and options to be exported from Oracle Database 11g release 2 (11.2.0.3) or later into an Oracle Database 12 c Release 1 (12.1) (either a multitenant container database (CDB) or a non-CDB).

Table 45-21 describes the valid operation types for the OPEN function.

Table 45-21 Valid Operation Types for the OPEN Function

Operation	Description
EXPORT	Saves data and metadata to a dump file set or obtains an estimate of the size of the data for an operation.
IMPORT	Restores data and metadata from a dump file set or across a database link.
SQL_FILE	Displays the metadata within a dump file set, or from across a network link, as a SQL script. The location of the SQL script is specified through the ADD_FILE procedure.

Table 45-22 describes the valid modes for the OPEN function.

Table 45-22 Valid Modes for the OPEN Function

Mode	Description
FULL	Operates on the full database or full dump file set except for Oracle Database internal schemas. (Some tables from Oracle Database internal schemas may be registered to be exported and imported in full operations in order to provide consistent metadata during import.) The TRANSPORTABLE parameter can be set to ALWAYS during a full database export in order to move data via transportable tablespaces rather than in the Data Pump dump file.
SCHEMA	Operates on a set of selected schemas. Defaults to the schema of the current user. All objects in the selected schemas are processed. In SCHEMA mode, you cannot specify Oracle-internal schemas (for example, SYS, XDB, ORDSYS, MDSYS, CTXSYS, ORDPLUGINS, or LBACSYS).
TABLE	Operates on a set of selected tables. Defaults to all of the tables in the current user's schema. Only tables and their dependent objects are processed.
TABLESPACE	Operates on a set of selected tablespaces. No defaulting is performed. Tables that have storage in the specified tablespaces are processed in the same manner as in Table mode.
TRANSPORTABLE	Operates on metadata for tables (and their dependent objects) within a set of selected tablespaces to perform a transportable tablespace export/import.

Return Values

• An opaque handle for the job. This handle is used as input to the following procedures: ADD_FILE, CREATE_JOB_VIEW, DATA_FILTER, DETACH, GET_STATUS, LOG_ENTRY, LOG_ERROR,METADATA_FILTER, METADATA_REMAP, METADATA_TRANSFORM, SET_PARALLEL,SET_PARAMETER, START_JOB,STOP_JOB, and WAIT_FOR_JOB

Exceptions

• INVALID_ARGVAL. An invalid operation or mode was specified. A NULL or invalid value was supplied for an input parameter. The error message text identifies the parameter.

• JOB_EXISTS. A table already exists with the specified job name.

• PRIVILEGE_ERROR. The user does not have the necessary privileges or roles to use the specified mode.

• INTERNAL_ERROR. The job was created under the wrong schema or the master table was of the wrong format.

• SUCCESS_WITH_INFO. The function succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• When the job is created, a master table is created for the job under the caller's schema within the caller's default tablespace. A handle referencing the job is returned that attaches the current session to the job. Once attached, the handle remains valid until either an explicit or implicit detach occurs. The handle is only valid in the caller's session. Other handles can be attached to the same job from a different session by using the ATTACH function.

• If the call to the OPEN function fails, call the GET_STATUS procedure with a null handle to retrieve additional information about the failure.

45.5.13 SET_PARALLEL Procedure

This procedure adjusts the degree of parallelism within a job.

Syntax

DBMS_DATAPUMP.SET_PARALLEL(
   handle      IN NUMBER,
   degree      IN NUMBER);

Parameters

Table 45-23 SET_PARALLEL Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.
degree	The maximum number of worker processes that can be used for the job. You use this parameter to adjust the amount of resources used for a job.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_OPERATION. The SET_PARALLEL procedure is only valid for export and import operations.

• INVALID_ARGVAL. An invalid value was supplied for an input parameter.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• The SET_PARALLEL procedure is only available in the Enterprise Edition of the Oracle database.

• The SET_PARALLEL procedure can be executed by any session attached to a job. The job must be in one of the following states: Defining, Idling, or Executing.

• The effect of decreasing the degree of parallelism may be delayed because ongoing work needs to find an orderly completion point before SET_PARALLEL can take effect.

• Decreasing the parallelism will not result in fewer worker processes associated with the job. It will only decrease the number of worker processes that will be executing at any given time.

• Increasing the parallelism will take effect immediately if there is work that can be performed in parallel.

• The degree of parallelism requested by a user may be decreased based upon settings in the resource manager or through limitations introduced by the PROCESSES or SESSIONSinitialization parameters in the init.ora file.

• To parallelize an Export job to a degree of n, the user should supply n files in the dump file set or specify a substitution variable in a file specification. Otherwise, some of the worker processes will be idle while waiting for files.

• SQL_FILE operations always operate with a degree of 1. Jobs running in the Transportable mode always operate with a degree of 1.

45.5.14 SET_PARAMETER Procedures

This procedure is used to specify job-processing options.

   name        IN VARCHAR2,
   value       IN NUMBER);

Parameters

Table 45-24 SET_PARAMETER Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to the OPEN function.
name	The name of the parameter. Table 45-25 describes the valid parameter names.
value	The value for the specified parameter

Table 45-25 describes the valid options for the name parameter of the SET_PARAMETER procedure.

Table 45-25 Valid Options for the name Parameter in the SET_PARAMETER Procedure

Parameter Name	Datatype	Supported Operations	Meaning
CLIENT_COMMAND	TEXT	All	An opaque string used to describe the current operation from the client's perspective. The command-line procedures will use this string to store the original command used to invoke the job.
COMPRESSION	TEXT	Export	Allows you to trade off the size of the dump file set versus the time it takes to perform export and import operations. The DATA_ONLY option compresses only user data in the dump file set. The METADATA_ONLY option compresses only metadata in the dump file set. The ALL option compresses both user data and metadata. The NONE option stores the dump file set in an uncompressed format. The METADATA_ONLY and NONE options require a job version of 10.2 or later. All other options require a job version of 11.1 or later. Default=METADATA_ONLY
COMPRESSION_ALGORITHM	TEXT	Export	Indicates the compression algorithm is to be used when compressing dump file data. The choices are as follows: BASIC--Offers a good combination of compression ratios and speed; the algorithm used is the same as in previous versions of Oracle Data Pump. LOW---Least impact on backup throughput and suited for environments where CPU resources are the limiting factor. MEDIUM---Recommended for most environments. This option, like the BASIC option, provides a good combination of compression ratios and speed, but it uses a different algorithm than BASIC. HIGH--Best suited for exports over slower networks where the limiting factor is network speed. To use this feature, the COMPATIBLE initialization parameter must be set to at least 12.0.0. This feature requires that the Oracle Advanced Compression option be enabled.
DATA_ACCESS_METHOD	TEXT	Export and Import	Allows you to specify an alternative method to unload data if the default method does not work for some reason. The choices are AUTOMATIC, DIRECT_PATH, or EXTERNAL_TABLE. Oracle recommends that you use the default option (AUTOMATIC) whenever possible because it allows Data Pump to automatically select the most efficient method.
DATA_OPTIONS	Number	Export and Import	A bitmask to supply special options for processing the job. The possible values are as follows: KU$_DATAOPT_SKIP_CONST_ERR KU$_DATAOPT_XMLTYPE_CLOB KU$_DATAOPT_DISABL_APPEND_HINT KU$_DATAOPT_GRP_PART_TAB KU$_DATAOPT_TRUST_EXIST_TB_PAR Export supports the value KU$_DATAOPT_XMLTYPE_CLOB. This option stores compressed XMLType columns in the dump file in CLOB format rather than as XML documents. Note: XMLType stored as CLOB is deprecated as of Oracle Database 12c Release 1 (12.1). Import supports the value KU$_DATAOPT_SKIP_CONST_ERR. This option specifies that if constraint violations occur while data is being imported into user tables, the rows that cause the violations will be rejected and the load will continue. If this option is not set, a constraint error will abort the loading of the entire partition (or table for unpartitioned tables). Setting this option may affect performance, especially for pre-existing tables with unique indexes or constraints. Import also supports the value KU$_DATAOPT_DISABL_APPEND_HINT. This option prevents the append hint from being applied to the data load. Disabling the APPEND hint can be useful if there is a small set of data objects to load that already exist in the database and some other application may be concurrently accessing one or more of the data objects. Data Pump Export supports the value KU$_DATAOPT_GRP_PART_TAB. This option tells Data Pump to unload all table data in one operation rather than unload each table partition as a separate operation. As a result, the definition of the table will not matter at import time because Import will see one partition of data that will be loaded into the entire table. Data Pump Import supports the value KU$_DATAOPT_TRUST_EXIST_TB_PAR. This option tells Data Pump to load partition data in parallel into existing tables. Use of the DATA_OPTIONS parameter requires that the version on the OPEN function be set to 11.1 or later. Default=0
ENCRYPTION	TEXT	Export	Specifies what to encrypt in the dump file set, as follows: ALL enables encryption for all data and metadata in the export operation. DATA_ONLY specifies that only data is written to the dump file set in encrypted format. ENCRYPTED_COLUMNS_ONLY specifies that only encrypted columns are written to the dump file set in encrypted format. METADATA_ONLY specifies that only metadata is written to the dump file set in encrypted format. NONE specifies that no data is written to the dump file set in encrypted format. This parameter requires a job version of 11.1 or later. The default value depends upon the combination of encryption-related parameters that are used. To enable encryption, either ENCRYPTION or ENCRYPTION_PASSWORDor both, must be specified. If only ENCRYPTION_PASSWORD is specified, then ENCRYPTION defaults to ALL. If neither ENCRYPTION nor ENCRYPTION_PASSWORD is specified, then ENCRYPTION defaults to NONE. To specify ALL, DATA_ONLY, or METADATA_ONLY, the COMPATIBLE initialization parameter must be set to at least 11.1. NOTE: If the data being exported includes SecureFiles that you want to be encrypted, then you must specify ENCRYPTION=ALL to encrypt the entire dump file set. Encryption of the entire dump file set is the only way to achieve encryption security for SecureFiles during a Data Pump export operation.
ENCRYPTION_ALGORITHM	TEXT	Export	Identifies which cryptographic algorithm should be used to perform encryption. Possible values are AES128, AES192, and AES256. The ENCRYPTION_ALGORITHM parameter requires that you also specify either ENCRYPTION or ENCRYPTION_PASSWORD; otherwise an error is returned. See Oracle Database Advanced Security Guide for information about encryption algorithms. This parameter requires a job version of 11.1 or later. Default=AES128
ENCRYPTION_MODE	TEXT	Export	Identifies the types of security used for encryption and decryption. The values are as follows: PASSWORD requires that you provide a password when creating encrypted dump file sets. You will need to provide the same password when you import the dump file set. PASSWORDmode requires that you also specify the ENCRYPTION_PASSWORD parameter. The PASSWORD mode is best suited for cases in which the dump file set will be imported into a different or remote database, but which must remain secure in transit. TRANSPARENT allows an encrypted dump file set to be created without any intervention from a database administrator (DBA), provided the required Oracle Encryption Wallet is available. Therefore, the ENCRYPTION_PASSWORD parameter is not required, and will in fact, cause an error if it is used in TRANSPARENT mode. This encryption mode is best suited for cases in which the dump file set will be imported into the same database from which it was exported. DUAL creates a dump file set that can later be imported using either the Oracle Encryption Wallet or the password that was specified with the ENCRYPTION_PASSWORD parameter. DUALmode is best suited for cases in which the dump file set will be imported on-site using the Oracle Encryption Wallet, but which may also need to be imported offsite where the Oracle Encryption Wallet is not available. When you use the ENCRYPTION_MODE parameter, you must also use either the ENCRYPTION or ENCRYPTION_PASSWORDparameter. Otherwise, an error is returned. To use DUAL or TRANSPARENT mode, the COMPATIBLEinitialization parameter must be set to at least 11.1. The default mode depends on which other encryption-related parameters are used. If only ENCRYPTION is specified, then the default mode is TRANSPARENT. If ENCRYPTION_PASSWORD is specified and the Oracle Encryption Wallet is open, then the default is DUAL. If ENCRYPTION_PASSWORD is specified and the Oracle Encryption Wallet is closed, then the default is PASSWORD.
ENCRYPTION_PASSWORD	TEXT	Export and Import	For export operations, this parameter is required if ENCRYPTION_MODE is set to either PASSWORD or DUAL. It is also required for transportable export/import operations (job mode=FULL and TRANSPORTABLE=ALWAYS) when the database includes either encrypted tablespaces or tables with encrypted columns.
ESTIMATE	TEXT	Export and Import	Specifies that the estimate method for the size of the tables should be performed before starting the job. If BLOCKS, a size estimate for the user tables is calculated using the count of blocks allocated to the user tables. If STATISTICS, a size estimate for the user tables is calculated using the statistics associated with each table. If no statistics are available for a table, the size of the table is estimated using BLOCKS. The ESTIMATE parameter cannot be used in Transportable Tablespace mode. Default=BLOCKS
ESTIMATE_ONLY	NUMBER	Export	Specifies that only the estimation portion of an export job should be performed. This option is useful for estimating the size of dump files when the size of the export is unknown.
FLASHBACK_SCN	NUMBER	Export and network Import	System change number (SCN) to serve as transactionally consistent point for reading user data. If neither FLASHBACK_SCN nor FLASHBACK_TIME is specified, there will be no transactional consistency between partitions, except for logical standby databases and Streams targets. FLASHBACK_SCN is not supported in Transportable mode.   For FLASHBACK_SCN, Data Pump supports the new 8–byte big SCNs used in Oracle Database 12c release 2 (12.2).
FLASHBACK_TIME	TEXT	Export and network Import	Either the date and time used to determine a consistent point for reading user data or a string of the form TO_TIMESTAMP(...). If neither FLASHBACK_SCN nor FLASHBACK_TIME is specified, there will be no transactional consistency between partitions. FLASHBACK_SCN and FLASHBACK_TIME cannot both be specified for the same job. FLASHBACK_TIME is not supported in Transportable mode.
INCLUDE_METADATA	NUMBER	Export and Import	If nonzero, metadata for objects will be moved in addition to user table data. If zero, metadata for objects will not moved. This parameter converts an Export operation into an unload of user data and an Import operation into a load of user data. INCLUDE_METADATA is not supported in Transportable mode. Default=1
KEEP_MASTER	NUMBER	Export and Import	Specifies whether the master table should be deleted or retained at the end of a Data Pump job that completes successfully. The master table is automatically retained for jobs that do not complete successfully. Default=0.
LOGTIME	TEXT	Export and Import	Specifies that messages displayed during export and import operations be timestamped. Valid options are as follows: NONE--No timestamps on status or log file messages (this is the default) STATUS--Timestamps on status messages only LOGFILE--Timestamps on log file messages only ALL--Timestamps on both status and log file messages
MASTER_ONLY	NUMBER	Import	Indicates whether to import just the master table and then stop the job so that the contents of the master table can be examined. Default=0.
METRICS	NUMBER	Export and Import	Indicates whether additional information about the job should be reported to the Data Pump log file. Default=0.
PARTITION_OPTIONS	TEXT	Import	Specifies how partitioned tables should be handled during an import operation. The options are as follows: NONE means that partitioning is reproduced on the target database as it existed in the source database. DEPARTITION means that each partition or subpartition that contains storage in the job is reproduced as a separate unpartitioned table. Intermediate partitions that are subpartitioned are not re-created (although their subpartitions are converted into tables). The names of the resulting tables are system-generated from the original table names and partition names unless the name is overridden by the REMAP_TABLE metadata transform. MERGE means that each partitioned table is re-created in the target database as an unpartitioned table. The data from all of the source partitions is merged into a single storage segment. This option is not supported for transportable jobs or when the TRANSPORTABLE parameter is set to ALWAYS. This parameter requires a job version of 11.1 or later. Default=NONE
REUSE_DATAFILES	NUMBER	Import	Specifies whether the import job should reuse existing data files for tablespace creation. Default=0.
SKIP_UNUSABLE_INDEXES	NUMBER	Import	If nonzero, rows will be inserted into tables having unusable indexes. SKIP_UNUSABLE_INDEXES is not supported in Transportable mode. Default=1
SOURCE_EDITION	TEXT	Export and network Import	The application edition that will be used for determining the objects that will be unloaded for export and for network import.
STREAMS_CONFIGURATION	NUMBER	Import	Specifies whether to import any Streams metadata that may be present in the export dump file. Default=1.
TABLE_EXISTS_ACTION	TEXT	Import	Specifies the action to be performed when data is loaded into a preexisting table. The possible actions are: TRUNCATE, REPLACE, APPEND, and SKIP. If INCLUDE_METADATA=0, only TRUNCATE and APPEND are supported. If TRUNCATE, rows are removed from a preexisting table before inserting rows from the Import. Note that if TRUNCATE is specified on tables referenced by foreign key constraints, the TRUNCATE will be modified into a REPLACE. If REPLACE, preexisting tables are replaced with new definitions. Before creating the new table, the old table is dropped. If APPEND, new rows are added to the existing rows in the table. If SKIP, the preexisting table is left unchanged. TABLE_EXISTS_ACTION is not supported in Transportable mode. The default is SKIP if metadata is included in the import. The default is APPEND if INCLUDE_METADATA is set to 0.
TABLESPACE_DATAFILE	TEXT	Import	Specifies the full file specification for a data file in the transportable tablespace set. TABLESPACE_DATAFILE is only valid for transportable mode imports. TABLESPACE_DATAFILE can be specified multiple times, but the value specified for each occurrence must be different.
TARGET_EDITION	TEXT	Import	The application edition that will be used for determining where the objects will be loaded for import and for network import.
TRANSPORTABLE	TEXT	Export (and network import or full-mode import)	This option is for export operations done in table mode, and also for full-mode imports and network imports. It allows the data to be moved using transportable tablespaces. In table-mode storage segments in the moved tablespaces that are not associated with the parent schemas (tables) will be reclaimed at import time. If individual partitions are selected in a table-mode job, only the tablespaces referenced by those partitions will be moved. During import, the moved partitions can only be reconstituted as tables by using the PARTITION_OPTIONS=DEPARTITION parameter. Use of the TRANSPORTABLE parameter prohibits the subsequent import of the dump file into a database at a lower version or using different character sets. Additionally, the data files may need to be converted if the target database is on a different platform. In table-mode, the TRANSPORTABLE parameter is not allowed if a network link is supplied on the OPEN call. The possible values for this parameter are as follows: ALWAYS - data is always moved by moving data files. This option is valid only for table mode and full mode. NEVER - data files are never used for copying user data This parameter requires a job version of 11.1 or later This parameter requires a job version of 12.1 or later when the job mode is FULL. Default=NEVER
TTS_FULL_CHECK	NUMBER	Export	If nonzero, verifies that a transportable tablespace set has no dependencies (specifically, IN pointers) on objects outside the set, and vice versa. Only valid for Transportable mode Exports. Default=0
USER_METADATA	NUMBER	Export and network Import	For schema-mode operations, specifies that the metadata to re-create the users' schemas (for example, privilege grants to the exported schemas) should also be part of the operation if set to nonzero. Users must be privileged to explicitly set this parameter. The USER_METADATA parameter cannot be used in Table, Tablespace, or Transportable Tablespace mode. Default=1 if user has DATAPUMP_EXP_FULL_DATABASE role; 0 otherwise.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_ARGVAL. This exception could be due to any of the following causes:

  • An invalid name was supplied for an input parameter

  • The wrong datatype was used for value

  • A value was not supplied

  • The supplied value was not allowed for the specified parameter name

  • A flashback parameter had been established after a different flashback parameter had already been established

  • A parameter was specified that did not support duplicate definitions

• INVALID_OPERATION. The operation specified is invalid in this context.

• INVALID_STATE. The specified job is not in the Defining state.

• INCONSISTENT_ARGS. Either the specified parameter is not supported for the current operation type or it is not supported for the current mode.

• PRIVILEGE_ERROR. The user does not have the DATAPUMP_EXP_FULL_DATABASE or DATAPUMP_IMP_FULL_DATABASE role required for the specified parameter.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• The SET_PARAMETER procedure is used to specify optional features for the current job. See Table 45-25 for a list of supported options.

45.5.15 START_JOB Procedure

This procedure begins or resumes job execution.

Syntax

DBMS_DATAPUMP.START_JOB (
   handle       IN NUMBER,
   skip_current    IN  NUMBER DEFAULT 0,
   abort_step      IN  NUMBER DEFAULT 0,
   cluster_ok      IN  NUMBER DEFAULT 1,
   service_name    IN  VARCHAR2 DEFAULT NULL);

Parameters

Table 45-26 START_JOB Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.
skip_current	If nonzero, causes actions that were 'in progress' on a previous execution of the job to be skipped when the job restarts. The skip will only be honored for Import jobs. This mechanism allows the user to skip actions that trigger fatal bugs and cause the premature termination of a job. Multiple actions can be skipped on a restart. The log file will identify which actions are skipped. If a domain index was being processed, all pieces of the domain index are skipped even if the error occurred in only a subcomponent of the domain index. A description of the actions skipped is entered into the log file. skip_current is ignored for the initial START_JOB in a job. If zero, no data or metadata is lost upon a restart.
abort_step	Value must be 0. Inserting values other than 0 into this argument will have unintended consequences.
cluster_ok	If = 0, all workers are started on the current instance. Otherwise, workers are started on instances usable by the job.
service_name	If specified, indicates a service name used to constrain the job to specific instances or to a specific resource group.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID_STATE. The causes of this exception can be any of the following:

  • No files have been defined for an Export, non-network Import, or SQL_FILE job

  • An ADD_FILE procedure has not been called to define the output for a SQL_FILE job

  • A TABLESPACE_DATAFILE parameter has not been defined for a Transportable Import job

  • A TABLESPACE_EXPR metadata filter has not been defined for a Transportable or Tablespace mode Export or Network job

  • The dump file set on an Import or SQL_FILE job was either incomplete or missing a master table specification

• INVALID_OPERATION. Unable to restore master table from a dump file set.

• INTERNAL_ERROR. An inconsistency was detected when the job was started. Additional information may be available through the GET_STATUS procedure.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• When this procedure is called to request that the corresponding job be started or restarted, the state of the job is changed from either the Defining or Idling state to the Executing state.

• If the SET_PARALLEL procedure was not called prior to the START_JOB procedure, the initial level of parallelism used in the job will be 1. If SET_PARALLEL was called prior to the job starting, the degree specified by the last SET_PARALLEL call determines the parallelism for the job. On restarts, the parallelism is determined by the previous parallel setting for the job, unless it is overridden by another SET_PARALLEL call.

• To restart a stopped job, an ATTACH function must be performed prior to executing the START_JOB procedure.

45.5.16 STOP_JOB Procedure

This procedure terminates a job, but optionally, preserves the state of the job.

Syntax

DBMS_DATAPUMP.STOP_JOB (
   handle      IN NUMBER,
   immediate   IN NUMBER DEFAULT 0,
   keep_master IN NUMBER DEFAULT NULL,
   delay       IN NUMBER DEFAULT 60);

Parameters

Table 45-27 STOP_JOB Procedure Parameters

Parameter	Description
handle	The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. At the end of the procedure, the user is detached from the handle.
immediate	If nonzero, the worker processes are aborted immediately. This halts the job quickly, but parts of the job will have to be rerun if the job is ever restarted. If zero, the worker processes are allowed to complete their current work item (either metadata or table data) before they are terminated. The job is placed in a Stop Pending state while the workers finish their current work.
keep_master	If nonzero, the master table is retained when the job is stopped. If zero, the master table is dropped when the job is stopped. If the master table is dropped, the job will not be restartable. If the master table is dropped during an export job, the created dump files are deleted.
delay	The number of seconds to wait until other attached sessions are forcibly detached. The delay allows other sessions attached to the job to be notified that a stop has been performed. The job keeps running until either all clients have detached or the delay has been satisfied. If no delay is specified, then the default delay is 60 seconds. If a shorter delay is used, clients might not be able to retrieve the final messages for the job through the GET_STATUS procedure.

Exceptions

• INVALID_HANDLE. The specified handle is not attached to a Data Pump job.

• INVALID STATE. The job is already in the process of being stopped or completed.

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS procedure.

• NO_SUCH_JOB. The specified job does not exist.

Usage Notes

• This procedure is used to request that the corresponding job stop executing.

• The termination of a job that is in an Executing state may take several minutes to complete in an orderly fashion.

• For jobs in the Defining, Idling, or Completing states, this procedure is functionally equivalent to the DETACH procedure.

• Once a job is stopped, it can be restarted using the ATTACH function and START_JOBprocedures, provided the master table and the dump file set are left intact.

• If the KEEP_MASTER parameter is not specified, and the job is in the Defining state or has a mode of Transportable, the master table is dropped. Otherwise, the master table is retained.

45.5.17 WAIT_FOR_JOB Procedure

This procedure runs a job until it either completes normally or stops for some other reason.

Syntax

DBMS_DATAPUMP.WAIT_FOR_JOB (
  handle      IN   NUMBER,
  job_state   OUT  VARCHAR2);

Parameters

Table 45-28 WAIT_FOR_JOB Procedure Parameters

Parameter	Description
handle	The handle of the job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. At the end of the procedure, the user is detached from the handle.
job_state	The state of the job when it has stopped executing; either STOPPED or COMPLETED.

Exceptions

• SUCCESS_WITH_INFO. The procedure succeeded, but further information is available through the GET_STATUS API.

• INVALID_HANDLE. The job handle is no longer valid.

Usage Notes

This procedure provides the simplest mechanism for waiting for the completion of a Data Pump job. The job should be started before calling WAIT_FOR_JOB. When WAIT_FOR_JOB returns, the job will no longer be executing. If the job completed normally, the final status will be COMPLETED. If the job stopped executing because of a STOP_JOB request or an internal error, the final status will be STOPPED.
