重新发现Oracle太美之awr相关脚本简单介绍
大家知道在$ORACLE_HOME/rdbms/admin下，有如下的相关脚本(我的环境为11.2.0.4.2):
[oracle@rh64 ~]$ cd $ORACLE_HOME/rdbms/admin
[oracle@rh64 admin]$ ls -ltr awr*

我们一一来介绍下：
1.awrrpt.sql
这个脚本大家都不陌生了吧，我们几乎去分析系统性能的时候都要去执行下这个脚本。我们来看看这里面有啥好玩的东西。
[oracle@rh64 admin]$ cat awrrpt.sql

Rem NAME
Rem awrrpt.sql
Rem
Rem DESCRIPTION
Rem This script defaults the dbid and instance number to that of the
Rem current instance connected-to, then calls awrrpti.sql to produce
Rem the Workload Repository report.
Rem
Rem NOTES
Rem Run as select_catalog privileges.
Rem This report is based on the Statspack report.
Rem
Rem If you want to use this script in an non-interactive fashion,
Rem see the 'customer-customizable report settings' section in
Rem awrrpti.sql

------>>>看到说明了吗？这个脚本只能抓取本示例的性能信息，其实这个脚本是调用的awrrpti.sql,AWR的开发是基于以前9i的Statspack report.
从10G开始才有AWR的，以前9I都是statspack,以前都是经常听老DBA说statspack,表示不明觉历。同时要运行这个脚本起码要有select_catalog的权限。
