在節點node2 以oracle使用者登入sqlplus
資料例項是idle的，嘗試startup啟動出錯“ORA-01102: cannot mount database in EXCLUSIVE mode”
[oracle@node2 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Jul 1 23:20:56 2014

Connected to an idle instance.
SYS@PROD2> startup
ORA-01102: cannot mount database in EXCLUSIVE mode
SYS@PROD2>
檢視alert日誌
[oracle@node2 ~]$ vi /s01/diag/rdbms/prod/PROD2/trace/alert_PROD2.log
…..

lmon registered with NM - instance number 2 (internal mem no 1)
USER (ospid: 4743): terminating the instance due to error 1102

用健康的節點node1登入，發現節點node1的例項PROD1的cluster_database屬性為false ！
[oracle@node1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Jul 1 23:34:10 2014

Data Mining and Real Application Testing options
SYS@PROD1> show parameter cluster_database;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
cluster_database boolean FALSE
cluster_database_instances integer 1
修改spfile中的引數，初步斷定問題的原因是此處導致！
SYS@PROD1> alter system set cluster_database=TRUE scope=spfile sid='PROD1';
System altered.
SYS@PROD1> alter system set cluster_database_instances=2 scope=spfile sid=‘PROD1';
System altered.
退出sqlplus，su到grid使用者下關閉資料庫
[grid@node1 ~]$ srvctl stop database -d prod;
檢視叢集資源狀態，兩個節點的資料庫例項都是shutdown的狀態
[grid@node1 ~]$ crsctl status res -t
