1、1：停止数据库
[oracle@qidong2 ~]$ srvctl stop database -d orcl
2、2：查看需要更改某一节点的VIP
[oracle@qidong2 ~]$ srvctl config vip -n qidong2
VIP exists: /qidong2vip/173.18.0.10/173.18.0.0/255.255.255.0/em1, hosting node qidong2
3、3：停止监听并查看状态
[oracle@qidong2 ~]$ srvctl stop listener -n qidong2
[oracle@qidong2 ~]$ srvctl status listener -n qidong2
Listener LISTENER is enabled on node(s): qidong2
Listener LISTENER is not running on node(s): qidong2
4、4：停止vip并查看状态
[oracle@qidong2 ~]$ srvctl stop vip -n qidong2
[oracle@qidong2 ~]$ srvctl status vip -n qidong2
VIP qidong2vip is enabled
VIP qidong2vip is not running
5、5：修改各个节点的 /etc/hosts 文件
修改对应的vip的IP
将节点2的vip 173.18.0.10 修改成 173.18.0.12
6、6：修改需要更改某一节点的vip
[oracle@qidong2 ~]$ srvctl modify nodeapps -n qidong2 -A 173.18.0.12/255.255.255.0/em1
[oracle@qidong2 ~]$ srvctl config vip -n qidong2 修改后检测
VIP exists: /qidong2vip/173.18.0.12/173.18.0.0/255.255.255.0/em1, hosting node qidong2
7、7：启动vip
[oracle@qidong2 ~]$ srvctl start vip -n qidong2
[oracle@qidong2 ~]$ srvctl status vip -n qidong2
VIP qidong2vip is enabled
VIP qidong2vip is running on node: qidong2
8、8：启动监听
[oracle@qidong2 ~]$ srvctl start listener -n qidong2
[oracle@qidong2 ~]$ srvctl status listener -n qidong2
Listener LISTENER is enabled on node(s): qidong2
Listener LISTENER is running on node(s): qidong2
9、9：启动数据库
[oracle@qidong2 ~]$ srvctl start database -d orcl
10、10：查看该节点的 local_listener
重启数据库由oraagent自动将vip注册进去
SQL> show parameter local_listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (ADDRESS=(PROTOCOL=TCP)(HOST=
173.18.0.12)(PORT=1521))
