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

[oracle@xxx~]$ cat $ORACLE_HOME/rdbms/admin/addmrpt.sql |grep -v "#"|grep -v "-"|grep -v "Rem"|grep -v "^$"

define num_days= 3;set heading on echo off feedback off verify off underline on timing off;column inst_num heading "Inst Num" new_value inst_num format 99999;columninst_name heading "Instance" new_value inst_name format a12;column db_name heading "DB Name" new_value db_nameformat a12;column dbid heading "DB Id" new_value dbid format 9999999999just c;

将ADDM sql脚本整合到自定义调用AWR shell脚本中

Script:

# auto gather awrrpt.sql

#

# parameters:

# $1 ->SID

#

# The whole package includes2files;

# oracle_auto_awr.sh(this file)

# ora_auto_awrrpt.sql

#

#引用oracle数据库环境变量
