目標：刪除第二節點的叢集服務

1.刪除之前狀態
[root@rac2 ~]# crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....B1.inst application    ONLINE    ONLINE    rac1
ora.RACDB.db   application    ONLINE    ONLINE    rac2
ora....DB1.srv application    ONLINE    ONLINE    rac1
ora.....taf.cs application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    ONLINE    rac1
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

2.以root使用者登入在第二個節點，執行指令碼rootdelete.sh
[root@rac2 ~]# /u01/crs1020/install/rootdelete.sh
CRS-0210: Could not find resource 'ora.rac2.LISTENER_RAC2.lsnr'.
Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.
Checking to see if Oracle CRS stack is down...
Oracle CRS stack is not running.
Oracle CRS stack is down now.
Removing script. for Oracle Cluster Ready services
Updating ocr file for downgrade
Cleaning up SCR settings in '/etc/oracle/scls_scr'

3.在第一節點以root身份執行rootdeletenode.sh指令碼
[root@rac1 ~]# /u01/crs1020/bin/olsnodes -n
rac1    1
rac2    2
[root@rac1 ~]# /u01/crs1020/install/rootdeletenode.sh rac2 2
CRS nodeapps are deleted successfully
clscfg: EXISTING configuration version 3 detected.
clscfg: version 3 is 10G Release 2.
Node deletion operation successful.
'rac2' deleted successfully

rootdeletenode.sh指令碼後緊跟的兩個引數分別是第二節點主機名和節點編號。

4.確認刪除後的狀態
[root@rac2 ~]# crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.

[root@rac1 ~]# crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....B1.inst application    ONLINE    ONLINE    rac1
ora.RACDB.db   application    ONLINE    ONLINE    rac1
ora....DB1.srv application    ONLINE    ONLINE    rac1
ora.....taf.cs application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    ONLINE    rac1
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1

OK，此時節點二上的叢集服務已經被移除。

Good luck.
