用存储过程封装awrrpt脚本(三)

原创 Linux操作系统 作者:yangtingkun 时间:2011-03-20 23:46:41 0 删除 编辑

做了一个存储过程,封装了awrreport的功能。

增加了对指定数据库生成报告的功能,修改了输入参数为字符串类型,修改输出AWR文件包含日期信息。

修改后的过程如下:

默认状态下运行:

SQL> SELECT NAME FROM V$DATABASE;

NAME
---------
TEST08

SQL> EXEC P_AWR_REPORT('20101115080000', '20101115100000', 'D_OUTPUT')

PL/SQL procedure successfully completed.

检查报告生成情况:

[oracle@yans1 ~]$ cd /home/oracle
[oracle@yans1 ~]$ ls *.html
awr_TEST08_1_20110114010035_20110114030037.html

如果指定数据库名生成报告:

SQL> EXEC P_AWR_REPORT('20101115080000', '20101115100000', 'D_OUTPUT', 'TESTRAC')

PL/SQL procedure successfully completed.
