自动生成AWR

1 需求

每天定时发送重要的数据库AWR到DBA邮件中，DBA接收到AWR邮件之后简单查看数据库是否有异常等待事情和异常SQL，尽量避免等用户发现数据库慢时再去分析相关SQL

2 相关环境

操作系统

本脚本是放在Red Hat下面运行，其它操作系统上面运行还未测试，因为使用的是dbms_workload_repository生成报表，所以可以分析任何操作系统下面的数据库，也就是说和数据库的操作系统没有关系

数据库版本

本脚本可以分析Oracle 10g ,11g任何子版本数据库

3 脚本详细介绍

脚本存放目录和文件

[oracle@svr7-71 awrrpt]$ pwd

/home/oracle/awrrpt

[oracle@svr7-71 awrrpt]$ ls -lrt

-rwxrwx--- 1 oracle oinstall 1968 May 24 11:05 awrrpt.sh

drwxr-xr-x 2 oracle oinstall 4096 May 24 11:09 reports

-rwxrwx--- 1 oracle oinstall 360 May 24 11:52 run.sh



其中awrrpt.sh为生成AWR的脚本，reports为存放生成后的AWR报告的文件夹

,run.sh为生成AWR的入口可以配置多个数据库



[oracle@svr7-71 awrrpt]$ more awrrpt.sh

#!/bin/bash

# $1 startTime

# $2 endTime

# $3 TNS user/passpassword@sid

from dba_hist_snapshot t
where t.end_interval_time between trunc(sysdate) + $1 / 24 and

spool $FILE_NAME;
select output from table(dbms_workload_repository.AWR_REPORT_HTML(&dbid, &instance_number,&begin_snap, &end_snap,0 ));
spool off;
EOF



echo "Report file name is : "$FILE_NAME

echo "AWR report of

$INSTANCE_NAME " | mutt -s "[info]AWR report of $INSTANCE_NAME ${TODAY}" -a "$FILE_NAME" linux@https://www.sodocs.net/doc/f22989516.html,

发送的邮件和主题不要忘记修改，run.sh我们在下面进行介绍

4 使用方法

可以看到调用awrrpt脚本需要传三个参数，分别为开始时间，结束时间，连接数据库的用户名密码还有tns，下面Run.sh配置了两个数据9点至11点的AWR报告，数据库只需要修改run.sh就可以了



[oracle@svr7-71 awrrpt]$ more run.sh

./awrrpt.sh 9 11 test1/test1@ora71
