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。
AWR的导出并不复杂，利用有权限的用户调用$ORACLE_HOME/rdbms/admin/awrextr.sql脚本就可以了：
SQL> @?/rdbms/admin/awrextr.sql
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Disclaimer: This SQL/Plus script. should only be called under
the guidance of Oracle Support.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~
AWR EXTRACT
~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~ This script. will extract the AWR data for a range of snapshots ~
~ into a dump file. The script. will prompt users for the ~
~ following information: ~
~ (1) database id ~
~ (2) snapshot range to extract ~
~ (3) name of directory object ~
~ (4) name of dump file ~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The default database id is the local one: ' 96312462'. To use this
database id, press <return> to continue, otherwise enter an alternative.
输入dbid的值:
Using 96312462 for Database ID
Specify the number of days of snapshots to choose from
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Entering the number of days (n) will result in the most recent
(n) days of snapshots being listed. Pressing <return> without
specifying a number lists all completed snapshots.
输入num_days的值: 3
Listing the last 3 days of Completed Snapshots
DB Name Snap Id Snap Started

已成功加载/卸载了主表"SYS"."SYS_EXPORT_TABLE_01"
******************************************************************************
SYS.SYS_EXPORT_TABLE_01的转储文件集为:
/data1/awr/awr_testrac_2782_2806.dmp
作业"SYS"."SYS_EXPORT_TABLE_01"已于17:32:11成功完成
操作执行后，会生成两个文件，一个导出的dmp文件，另一个日志文件：
SQL> host ls -l /data1/awr/awr_testrac*
-rw-rw---- 1 oracle oinstall 17158144 Nov 16 17:32 /data1/awr/awr_testrac_2782_2806.dmp
-rw-rw-r-- 1 oracle oinstall 25939 Nov 16 17:32 /data1/awr/awr_testrac_2782_2806.log
其中dmp文件就是脚本利用数据泵导出的snap数据，将这个文件拷贝到目标数据库上执行导入，就可以实现AWR数据的迁移。
