(Oracle)自定义调用AWR&ADDM

Oracle->自定义调用AWR&ADDM

需求描述：

　　前面设定每天自动生成AWR用于提供前一天的数据库状态信息，但因数据库和信息过多不利于直观检查。此次新增ADDM诊断。

ADDM诊断脚本分析：

　　　　$ORACLE_HOME/rdbms/admin/addmrpt.sql--ADDM自动诊断资料库的主脚本

　　　　　　用于显示当前的数据库和实例，并调用@@addmrpti.sql脚本

将ADDM sql脚本整合到自定义调用AWR shell脚本中

Script:
[oracle@ ~]$ cat /opt/app/oracle/ora_auto/oracle_auto_awr.sh
#!/bin/bash

# auto gather awrrpt.sql
#
# parameters:
# $ -> SID
#
# The whole package includes  files;
#   oracle_auto_awr.sh(this file)
#   ora_auto_awrrpt.sql
#

#引用oracle数据库环境变量
