概述
Oracle Database 10g 提供了一个新的工具：(AWR:Automatic Workload Repository) .
AWR 实质上是一个 Oracle 的内置工具，它采集与性能相关的统计数据，并从那些统计数据中导出性能量度，以跟踪潜在的问题。
首先进入$ORACLE_HOME/rdbms/admin目录，在sqlplus下运行@awrrpt脚本，按照提示一步一步就可以达成，导出的格式有两种，txt格式和html格式。

awrrpt.sql
如果不知道 awrrpt.sql的脚本在哪里，利用locate命令可以快速的查找到
切到oracle用户下执行以下操作。
SQL> @?/rdbms/admin/awrrpt.sql
等待即可…
退出sql窗口，切到刚才的目录，查看 cc_awr_rpt_20160906.html
找不到了就locate一下 ，使用root用户
generate_multiple_awr_reports
