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 db_name heading "DB Name" new_value db_name format a12;

$ORACLE_HOME/rdbms/admin/addmrpti.sql —查询当前snapshot快照点，接收用户输入，设置和执行dbms_advisor程序包。
