概述
我们知道，Oracle提供的脚本均位于下列目录下
$ORACLE_HOME/rdbms/admin其中，
awrsqrpt.sql用来分析某条指定的SQL语句，通过awrsqrpt.sql脚本，awr能够生成指定曾经执行过的SQL的执行计划，当时消耗的资源等情况。
常用的几个如下：
- awrrpt.sql ：生成指定快照区间的统计报表
- awrrpti.sql ：生成指定数据库实例，并且指定快照区间的统计报表
- awrsqlrpt.sql ：生成指定快照区间，指定SQL语句(实际指定的是该语句的SQLID)的统计报表
- awrsqrpi.sql ：生成指定数据库实例，指定快照区间的指定SQL语句的统计报表
- awrddrpt.sql ：指定两个不同的时间周期，生成这两个周期的统计对比报表
- awrddrpi.sql ：指定数据库实例，并指定两个的不同时间周期，生成这两个周期的统计对比报表
- addmrpt.sql：数据库自动诊断监视工具（Automatic Database Diagnostic Monitor :ADDM）
- addmrpti.sql：指定数据库实例，数据库自动诊断监视工具（Automatic Database Diagnostic Monitor :ADDM）
调用后台脚本awrsqrpt.sql获取
