本實驗是在Redhat 6.5 && Oracle 11.2.0.4 RAC 環境下做的，生產中有時會需要修改RAC的VIP（虛擬IP），往往

一些Oracle 學習愛好者或者相關管理人員在進行修改時遇到各類問題，這裡我將自己的實驗過程展示出來，希望能給

更多的Oracle 學習愛好者一些幫助。

本次實驗是要將節點2的VIP（虛擬IP）：192.168.80.13   修改成：192.168.80.16 
具體操作步驟如下：

以root使用者執行

[root@vastdata2 ~]# cd /u01/app/11.2.0/grid/bin/

[root@vastdata2 bin]# ./srvctl config vip -n vastdata2
 

VIP exists: /vastdata2-vip/192.168.80.13/192.168.80.0/255.255.255.0/eth0, hosting node vastdata2

修改VIP地址–該命令給出了新的VIP地址“192.168.80.16”、網路掩碼“255.255.255.0”和VIP使用的網絡卡“eth0”。

[root@vastdata2 bin]# ./srvctl modify nodeapps -n vastdata2 -A 192.168.80.16/255.255.255.0/eth0
