Oracle RAC集群删除节点

一,节点环境　

[root@node1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.194 node2
192.168.0.193 node1
192.168.0.183 node1vip
192.168.0.182 node2vip
172.168.0.194 node2prv
172.168.0.193 node1prv
192.168.0.176 dbscan
192.168.0.16 standby

二,操作实例

　　01,dbca 删除节点host02

　　　　登入oracle 用户运行dbca-->进行删除数据库-->delete databases 下一步

!!!----------------------------注意--------------------------!!!

选择数据库请认真核对.确定数据安全性!!,删除前再三思考!!选项是英文,请看懂英文再选择!!

输入用户sys,密码123456,具体根据自己的来填写

为啥到这一步出问题了呢,因为我在node2节点删除node2节点,自己删自己当然不允许啦,现在我换个节点node1操作把

到了node1删除的时候会发现自动选择node2节点

node1 上查看节点是否存在

----------------------------------------------------

三,清理

　　01,发现节点还在,资源也还在

 [grid@node1 ~]$ crsctl status resource -t

　　02,停掉监听

格式:

srvctl stop listener -l listener_name -n name_of_node_to_delete
 操作:
srvctl disable listener -l listener -n node2
srvctl stop listener -l listener -n node2
