AWR 导出/导入/生成报告

2024-10-26 分类：聚合分类

      客户的生产系统总是那么重要，一般不会让你长时间的在他们的生产机器上做操作，但是分析和生成AWR报告都是一个相对耗时的工作，当然只生成一个AWR报告是不费时的，但是要对系统进行详细分析的时候，我们可能需要的是一段时间内的所有AWR数据，需要根据实际情况进行选取。这时我们就需要将客户的AWR数据导出，然后进行分析，这个操作主要涉及AWR数据导出、导入和生成报告三个阶段，下面对每个步骤进行详细描述。
     1、导出

  1. SQL> @?/rdbms/admin/awrextr.sql

  15. ~ into a dump file. The script will prompt users for the     ~
  16. ~ following information:                     ~
  17. ~ (1) database id                         ~
  18. ~ (2) snapshot range to extract                 ~

  65. press <return> to continue, otherwise enter an alternative.
  67. Enter value for report_name: /oracle/app/oracle/admin/gyl/dpdump/awr_rac.html

       整个过程都很简单，但有几点需要注意：
      1、不能将同一个数据库的AWR数据导出后再导入到自己，这样会遇到下面的错误
            ERROR at line 1:
             ORA-20105: unable to move AWR data to SYS
             ORA-06512: at “SYS.DBMS_SWRF_INTERNAL”, line 2950
             ORA-20107: not allowed to move AWR data for local dbid
             ORA-06512: at line 3
       2、在导入的时候，在输入值时，尽量用大写；
       3、如果不再需要的数据，可以用如下存储过程删除：
            SQL> exec DBMS_SWRF_INTERNAL.UNREGISTER_DATABASE(bdid);     –将dbid换成需要删除的dbid号
