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
2、导入
先将上面生成的dump文件拷贝到目标机器的一个directory下,然后按如下操作进行导入。
3、生成报告
在目标机器上生成报告
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
