Oracle 11g r2 使用Data dump 从CentOS 迁移到Window 2012

****全库Expdp导出，再全库Impdp导入****

源系统：
操作系统：CentOS
Oracle数据库版本：Oracle11g  Enterprise Edition Release 11.2.0.1.0
SID：orcl
端口：1521

目标系统:
操作系统：Windows 2012
Oracle数据库版本：Oracle11g  Enterprise Edition Release 11.2.0.1.0
SID：orcl
端口：1521

---

源系统和目标系统都建立账号

create user username identified by password;
grant connect,resoure to username;

赋予expdp和impdp命令权限:

grant exp_full_database,imp_full_database to username;

SQL> create user migrate identified by migrate;
User created

SQL> grant connect,resource,dba to migrate;
Grant succeeded

SQL> grant exp_full_database,imp_full_database to migrate;
Grant succeeded

SQL> select * from dba_directories;
OWNER                          DIRECTORY_NAME                 DIRECTORY_PATH
------------------------------ ------------------------------ --------------------------------------------------------------------------------
SYS                            ORACLE_OCM_CONFIG_DIR          /oracle/app/product/11.2.0/dbhome_1/ccr/state
SYS                            DATA_PUMP_DIR                  /oracle/app/admin/orcl/dpdump/
SYS                            XMLDIR                         /ade/b/2125410156/oracle/rdbms/xml

Step 1: 在源系统上创建目录

create directory DPDMP as '/oracle/app/admin/orcl/dpdmp/'; --该目录必须是已经存在的目录（该目录应该用oracle用户创建），否则会报错

SQL> select * from dba_directories;
OWNER                          DIRECTORY_NAME                 DIRECTORY_PATH
------------------------------ ------------------------------ --------------------------------------------------------------------------------
SYS                            ORACLE_OCM_CONFIG_DIR          /oracle/app/product/11.2.0/dbhome_1/ccr/state
SYS                            DATA_PUMP_DIR                  /oracle/app/admin/orcl/dpdump/
SYS                            DPDMP                          /oracle/app/admin/orcl/dpdmp/
SYS                            XMLDIR                         /ade/b/2125410156/oracle/rdbms/xml

Step 2: 赋予账号对该目录的权限

grant read,write on directory DPDMP to username;

Step 3: 在源系统端expdp(基于某个用户)

expdp username/password@orcl directory= DPDMP dumpfile=XX_schema%U.dmp logfile=XX_schema.log schemas=XX_schema
或者导出整个库：
expdp username/password@orcl directory= DPDMP dumpfile=all%U.dmp logfile=XX_schema.log parallel=10 full=y

Step 4:将源系统的directory/XX_schema%U.dmp文件拷贝到目标系统

这步骤省略

Step 5: 在目标系统上创建目录

create directory DPDMP as 'E:\oracle\app\Administrator\admin\orcl\dpdmp'; --该目录必须是已经存在的目录，否则会报错

Step 6: 赋予权限

grant read,write on directory impdp to username;

Step 7: 在目标系统端impdp

impdp username/password@orcl directory= DPDMP dumpfile=XX_schema%U.dmp logfile=XX_schema.log schemas=XX_schema
或导入整个库:
impdp username/password@orcl directory= DPDMP dumpfile=all%U.dmp logfile=XX_schema.log parallel=10 full=y
impdp migrate/migrate@orcl directory=dpdmp dumpfile=migrate_full.dmp logfile=migrate_imp_full.log full=y parfile=e:\payroll.par parallel=10 
payroll.par放到directory impdp目录下或放到E盘根目录:
payroll.par文件内容
remap_datafile="'/oracle/app/oradata/orcl/XXX.dbf':'E:\ORACLE\APP\ADMINISTRATOR\ORADATA\ORCL\XXX.DBF'"
remap_datafile="'/oracle/app/oradata/orcl/XXX.dbf':'E:\ORACLE\APP\ADMINISTRATOR\ORADATA\ORCL\XXX.DBF'"
remap_datafile="'/oracle/app/oradata/orcl/XXX.dbf':'E:\ORACLE\APP\ADMINISTRATOR\ORADATA\ORCL\XXX.DBF'"

> 以下为迁移中可能使用到

• 如果需要从linux到window的导入导出，最好是先创建表空间及数据文件
  表空间DDL:

select ts.tablespace_name,to_char(dbms_metadata.get_DDl('TABLESPACE',ts.tablespace_name))from dba_tablespaces ts;

• 用户DDL：

select username,default_tablespace,temporary_tablespace,profile,dbms_metadata.get_DDl('USER',username) from dba_users where 
account_status='OPEN' ;

• 记录数:

 select table_name, count_rows(table_name) nrows from user_tables ;

• 查看当前导入的job ：

 select * from dba_datapump_jobs;

• 如果impdp过程中异常退出后，要从中断处继续导入执行如下:

  impdp migrate/migrate@orcl attach=JOB_NAME (JOB_NAME可以通过dba_datapump_jobs来查询)
  比如:> impdp mig_test/mig_test attach=SYS_IMPORT_TABLE_02

  Import status/continue_client 返回记录模式/stop_job YES/
  交互模式常用命令：
  CONTINUE_CLIENT返回到记录模式。假如处于空闲状态, 将重新启动作业。
  START_JOB 启动恢复当前作业。
  STATUS在默认值 (0) 将显示可用时的新状态的情况下,要监视的频率 (以秒计) 作业状态。
  STATUS=[interval]
  STOP_JOB顺序关闭执行的作业并退出客户机。
  STOP_JOB=IMMEDIATE 将立即关闭数据泵作业。

• 如果全库导入的时候会暂停卡在那里

  可以查diag\rdbms\orcl\orcl\trace\alert_orcl.log查看日志，针对当前问题解决掉后，impdp会继续
  如果是ORA-19815: WARNING: db_recovery_file_dest_size of 4039114752 bytes is 100.00% used, and has 0 remaining bytes available.
  就需要将db_recovery_file_dest_size调大:

SQL> alter system set db_recovery_file_dest_size=50G scope=spfile(需要重启数据库生效)
 SQL> shutdown immediate;
 SQL> startup;
 SQL> show parameter db_recovery_file_dest
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      E:\oracle\app\Administrator\flash_recovery_area
db_recovery_file_dest_size           big integer 50G
