1.關閉一個執行個體
[[email protected] ~]$ sqlplus / as sysdbaSQL> shutdown immediate;
2.備份spfile檔案
SQL> create pfile='/home/oracle/acct1.pfile' from spfile;
3.修改pfile檔案cluster_database為false
*.cluster_database=FALSE
4.使用pfile檔案,啟動單一實例資料庫到mount狀態
SQL> startup mount pfile='/home/oracle/acct1.pfile';
5.執行nid修改dbname
[[email protected] ~]$ nid target=sys/oracle dbname=crmdb setname=yDBNEWID: Release 11.2.0.4.0 - Production on Tue May 19 09:31:48 2015Copyright (c) 1982, 2011, Oracle and/or its affiliates.

6.修改ORACLE_SID資訊
------節點1------
6.1 環境變數
[[email protected] ~]$ vi .bash_profileexport ORACLE_SID=crmdb1
6.2 口令檔案
[[email protected] ~]$ cd $ORACLE_HOME/dbs[[email protected] dbs]$ orapwd file=orapwcrmdb1 password=oracle
6.3 修改pfile檔案啟動資料庫
*.cluster_database=TRUE*.db_name='crmdb'替換acct1為crmdb1 :%s/acct1/crmdb1/g替換acct2為crmdb2 :%s/acct2/crmdb2/g
6.4 建立新的spfile參數檔案
[[email protected] ~]$ sqlplus / as sysdbaSQL> startup pfile='/home/oracle/acct1.pfile' nomount;SQL> create spfile='+DATA_DG' from pfile='/home/oracle/acct1.pfile';
6.5 建立pfile參數檔案
[[email protected] ~]$ cd $ORACLE_HOME/dbs[[email protected] dbs]$ vi initcrmdb1.oraSPFILE='+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913'
------節點2------
1 環境變數
[[email protected] ~]$ vi .bash_profileexport ORACLE_SID=crmdb2
2. 口令檔案
[[email protected] ~]$ cd $ORACLE_HOME/dbs[[email protected] dbs]$ orapwd file=orapwcrmdb2 password=oracle
3. 參數檔案
[[email protected] dbs]$ vi initcrmdb2.oraSPFILE='+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913'
7.修改crs資源
7.1 刪除舊執行個體配置
[[email protected] ~]$ srvctl remove database -d acct
7.2 添加新執行個體配置
[[email protected] ~]$ srvctl add database -d crmdb -o /oracle/app/oracle/product/11.2.0/db_1/[[email protected] ~]$ srvctl add instance -d crmdb -i crmdb1 -n rac11g1[[email protected] ~]$ srvctl add instance -d crmdb -i crmdb2 -n rac11g2
