Oracle技术之AWR概述―导入

AWR的SNAP生成后，不一定要在原数据库上生成报告，可以利用AWR提供的导出、导入功能，将AWR数据迁移到测试数据库上进一步分析。

将上一篇文章导出的dmp文件拷贝到目标数据库的指定DIRECTORY目录下，就可以调用$ORACLE_HOME/rdbms/admin/awrload.sql脚本执行导入了：

SQL> @?/rdbms/admin/awrload.sql

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Disclaimer: This SQL/Plus script. should only be called under

the guidance of Oracle Support.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~

AWR LOAD

~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~  This script. will load the AWR data from a dump file. The   ~

~  script. will prompt users for the following information:    ~

~     (1) name of directory object                            ~

~     (2) name of dump file                                   ~

~     (3) staging schema name to load AWR data into           ~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Specify the Directory Name

~~~~~~~~~~~~~~~~~~~~~~~~~~

Directory Name                 Directory Path

------------------------------ -------------------------------------------------

ADMIN_DIR                      /opt/ora10g/product/10.2.0/db_1/md/admin

DATA_PUMP_DIR                  /opt/ora10g/product/10.2.0/db_1/rdbms/log/

DMP_DIR                        /data/backup

DUMP_DIR                       /home/oracle/shiyq/

DUMP_FILE_DIR                  /data/backup/dmp

D_OUTPUT                       /home/oracle

D_TRANS                        /data/oradata/test08

EXTDIR                         /home/oracle/script/

TRAN                           /data/backup

WORK_DIR                       /opt/ora10g/product/10.2.0/db_1/work

Choose a Directory Name from the list above (case-sensitive).

Enter value for directory_name: D_OUTPUT

Using the dump directory: D_OUTPUT

Specify the Name of the Dump File to Load

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Please specify the prefix of the dump file (.dmp) to load:

Enter value for file_name: awr_testrac_2782_2806

Loading from the file name: awr_testrac_2782_2806.dmp

Staging Schema to Load AWR Snapshot Data

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The next step is to create the staging schema

where the AWR snapshot data will be loaded.

After loading the data into the staging schema,

the data will be transferred into the AWR tables

in the SYS schema.

The default staging schema name is AWR_STAGE.

To use this name, press <return> to continue, otherwise enter

an alternative.

Enter value for schema_name:

Using the staging schema name: AWR_STAGE

Choose the Default tablespace for the AWR_STAGE user

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Choose the AWR_STAGE users's default tablespace.  This is the

tablespace in which the AWR data will be staged.

导入需要注意几点，输入DIRECTORY的时候注意大小写，另外输入导入的文件名时只输入前缀，不要输入完整的文件名。以这篇文档为例，输入文件名前缀为awr_testrac_2782_2806，如果输入awr_testrac_2782_2806.dmp则会导致错误。

在导致完成后，可以从dba_hist_snap中查询到导入数据库snap信息：

SQL> select snap_id, dbid, instance_number, to_char(begin_interval_time, 'yyyy-mm-dd hh24:mi:ss.ff')

 2  from dba_hist_snapshot  

 3  where dbid = 96312462

 4  order by 1, 3;

  SNAP_ID       DBID INSTANCE_NUMBER TO_CHAR(BEGIN_INTERVAL_TIME,'
