AWR元数据的迁移或导入到其他数据库

我们可以将AWR元数据迁移(导入)到其他数据库，低版本的导入到高版本，再用高版本的数据库生成AWR报告，也能使用一些新特性，如

SQL ordered by Physical Reads (UnOptimized)
SQL ordered by User I/O Wait Time

导出：

testnode:/home/oracle$export ORACLE_SID=wy1
testnode:/home/oracle$sqlplus / as sysdba
SQL> @?/rdbms/admin/awrextr.sql

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                                        ~

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

Enter value for directory_name: EXPDP   <<<<<<<<<输入DIRECTORY,右边是目录所对应的物理路径.注: 如果SNAP跨度大,需要较大的空间来存放文件

Using the dump directory: EXPDP

Specify the Name of the Extract Dump File
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The prefix for the default dump file name is awrdat_4707_4708.
To use this name, press <return> to continue, otherwise enter
an alternative.

Enter value for file_name:

Using the dump file prefix: awrdat_4707_4708

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:          <<<<<<<<<<<<<<回车,取默认值

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.
