Oracle環境：

版本：Oracle 11gR2 RAC （Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production）

Rac節點資訊：

主機名 SID SERVICE_NAME

rac1 racdb1 racdb

rac2 racdb2 racdb

Host檔案：

安裝過程：

1、建立asmsnmp使用者：

su - grid

sqlplus / as sysasm

create user asmsnmp identified by 123456;

grant sysdba to asmsnmp;

2、ASM例項註冊於listener_scan1：

alter system set remote_listener='racscan:1521' scope=both sid='*';

alter system register;

3、檢視cluster name：

/u01/app/11.2.0/grid/bin/cemutlo -n

4、重歸EM：

su - oracle

emca -config dbcontrol db -repos recreate -cluster

配置過程如下：

[oracle@rac1 ~]$ emca -config dbcontrol db -repos recreate -cluster
