Oracle 10g RAC删除、增加节点

一、查看状态
[root@rac1 bin]# ./crs_stat -t
Name           Type           Target    State     Host        
------------------------------------------------------------
ora....B1.inst application    ONLINE    ONLINE    rac1        
ora....B2.inst application    ONLINE    ONLINE    rac2        
ora.RACDB.db   application    ONLINE    ONLINE    rac2        
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....SM2.asm application    ONLINE    ONLINE    rac2        
ora....C2.lsnr application    ONLINE    ONLINE    rac2        
ora.rac2.gsd   application    ONLINE    ONLINE    rac2        
ora.rac2.ons   application    ONLINE    ONLINE    rac2        
ora.rac2.vip   application    ONLINE    ONLINE    rac2        
二、停止ASM实例
[root@rac1 bin]# ./srvctl stop asm -n rac1 -i +ASM1
[root@rac1 bin]# ./crs_stat -t
Name           Type           Target    State     Host        
------------------------------------------------------------
ora....B1.inst application    OFFLINE   OFFLINE               
ora....B2.inst application    ONLINE    ONLINE    rac2        
ora.RACDB.db   application    ONLINE    ONLINE    rac1        
ora....SM1.asm application    OFFLINE   OFFLINE               
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....SM2.asm application    ONLINE    ONLINE    rac2        
ora....C2.lsnr application    ONLINE    OFFLINE               
ora.rac2.gsd   application    ONLINE    ONLINE    rac2        
ora.rac2.ons   application    ONLINE    ONLINE    rac2        
ora.rac2.vip   application    ONLINE    OFFLINE             


三、移除ASM实例
[root@rac1 bin]# ./srvctl remove asm -n rac1 -i +ASM1
PRKS-1023 : Failed to remove CRS resource for ASM instance "+ASM1" on node "rac1", [CRS-0214: Could not unregister resource 'ora.rac1.ASM1.asm'.]


四、取消DB实例与ASM实例
[root@rac1 bin]# ./crs_unregister ora.RACDB.RACDB1.inst
[root@rac1 bin]# ./crs_unregister ora.rac1.ASM1.asm


五、查看状态、ASM与DB实例已经没有了
[root@rac1 bin]# ./crs_stat -t
Name           Type           Target    State     Host        
------------------------------------------------------------
ora....B2.inst application    OFFLINE   OFFLINE               
ora.RACDB.db   application    OFFLINE   OFFLINE               
ora....C1.lsnr application    OFFLINE   OFFLINE               
ora.rac1.gsd   application    ONLINE    ONLINE    rac1        
ora.rac1.ons   application    ONLINE    ONLINE    rac1        
ora.rac1.vip   application    ONLINE    ONLINE    rac1

ora.rac2.ons   application    ONLINE    ONLINE    rac2        
ora.rac2.vip   application    ONLINE    ONLINE    rac2       
六、查看节点信息
[root@rac1 bin]# ./olsnodes -n
rac1    1
rac2    2


七、在另外一个节点上、root用户下执行删除脚本
su - root


cd $ORACLE_HOME/install
export ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs_1
[root@rac2 install]# ./rootdeletenode.sh rac1
CRS nodeapps are deleted successfully

ora.rac2.ons   application    ONLINE    ONLINE    rac2        
ora.rac2.vip   application    ONLINE    ONLINE    rac2   
九、移除节点
[root@rac2 bin]# ./srvctl remove nodeapps -n rac1
Please confirm that you intend to remove the node-level applications on node rac1 (y/[n]) y
PRKO-2108 : Node applications are still running on node: rac1
十、查看状态
[root@rac2 bin]# ./crs_stat -t

十一、取消LISTENER、VIP、GSD、ONS服务注册
[root@rac2 bin]# ./crs_stat -l|grep C1.lsnr
NAME=ora.rac1.LISTENER_RAC1.lsnr
[root@rac2 bin]# ./crs_unregister ora.rac1.LISTENER_RAC1.lsnr


[root@rac2 bin]# ./crs_stop ora.rac1.vip
