修改vip
1、停库
[oracle@hca1 ~]$ srvctl stop database -d orcl
2、停止监听和vip
[grid@hca1 ~]$ srvctl stop listener -n hca1
[grid@hca1 ~]$ srvctl stop listener -n hca2
[grid@hca1 ~]$ srvctl stop vip -n hca1
[grid@hca1 ~]$ srvctl stop vip -n hca2
3、修改双节点/etc/hosts
4、root用户修改（hca1上可以下面command修改两个节点）
确认
[root@hca1 bin]# ./srvctl config vip -n hca1
VIP exists: /hca1-vip/172.16.80.25/172.16.0.0/255.255.0.0/em1, hosting node hca1
修改
/u01/app/11.2.0/grid/bin/srvctl modify nodeapps -n hca1 -A 172.16.80.15/255.255.0.0/em1
/u01/app/11.2.0/grid/bin/srvctl modify nodeapps -n hca2 -A 172.16.80.16/255.255.0.0/em1
5、
srvctl modify scan_listener -u
srvctl start scan_listener
修改scan
[grid@hca1 ~]$ crs_stat -t

[grid@hca1 ~]$
停监听
[grid@hca1 ~]$ srvctl stop scan_listener
[grid@hca1 ~]$ srvctl stop scan
修改
[root@hca1 ~]# /u01/app/11.2.0/grid/bin/srvctl modify scan -n rac-scan
[root@hca1 ~]#
[grid@hca1 ~]$ srvctl modify scan_listener -u
开启scan监听
[grid@hca1 ~]$ srvctl start scan_listener
[grid@hca1 ~]$ srvctl start scan
最后，再把库起来
[oracle@hca1 ~]$ srvctl start database -d orcl
看一下scan监听状态
[grid@hca1 ~]$ lsnrctl status LISTENER_SCAN1
