有时候数据库中为安装EM,无法图形化生成AWR报告,此时需要手工生成AWR报告,ORACLE提供了以个sql,可以手工生成AWR报告,首先创建生成报告的目录,这里为/home/oracle/AWR
$ mkdir AWR $ cd AWR $ pwd /home/oracle/AWR
进入sqlplus
[oracle@ocp ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Wed Dec 30 02:41:04 2015 Copyright (c) 1982, 2009, Oracle. All rights reserved.

执行脚本,?代表$ORACLE_HOME,@表示执行sql,默认提供两种报表格式,html和txt,默认为html格式
