Oracle快速收集AWR的方案
记一种方便的awr收集方法,该脚本可以按小时收集目标时段的awr
素材:awr_generate.sql(具体脚本内容请见本文末尾)
(1)将awr_generate.sql置于数据库服务器本地路径,如F:\perf\awr下
(2)sqlplus连接数据库
C:\Users\Administrator>sqlplus / as sysdba
(3)调用SQL脚本,时段参数等
SQL> @F:\perf\awr\awr_generate.sql

Specify the number of days of snapshots to choose from
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Entering the number of days (n) will result in the most recent
(n) days of snapshots being listed. Pressing <return> without
specifying a number lists all completed snapshots.
输入 num_days 的值: 1
