Oracle AWR报告生成步骤



Oracle AWR 是通过对比两次快照(snapshot)收集到的统计信息,来生成报表数据,生成的报表包括多个部分,这点与Statspack生成的报告非常类似。不过AWR在生成报告时,可以选择生成TXT或HTML两种格式的报告,相对来说,HTML更利于阅读,而TXT的适用性更广(即使在不能使用浏览器的机器上也能看)。

操作过Statspack的朋友都还记的,生成报告使用$ORACLE_HOME/rdbms/admin/spreport.sql脚本,到了AWR这片,操作步骤基本上相同,不过生成报告的脚本多了很多选择,包括:
•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;

报表的生成流程如下:

(1)进入命令行,切换到自己的工作目录:

Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.

C:\Documents and Settings\Administrator>d:

D:\>

说明:此处切换目录是为了设定生成报表文件的存放位置。

(2)使用sqlplus命令行工具登录连接数据库

Disconnected from Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options

D:\>sqlplus /nolog

SQL*Plus: Release 10.1.0.2.0 - Production on 星期四 5月 20 16:48:19 2010

(3)运行生成报表SQL文件:@D:\oracle\product\10.1.0\Db_1\RDBMS\ADMIN\awrrpt.sql

SQL> @D:\oracle\product\10.1.0\Db_1\RDBMS\ADMIN\awrrpt.sql
