oracle 11gR2 如何修改vip

因為業務需要，需要將p570a主機和p570b主機上的vip做修改

修改前ip

192.168.128.12   p570a-vip

192.168.128.13   p570b-vip

 

修改後ip

10.76.31.113   p570a-vip

10.76.31.115   p570b-vip

 

兩個節點的/etc/hosts 檔案要修改為修改後的vip

以下為具體步驟：

1.關閉database

 

 root使用者下執行以下命令

 cd /grid/app/11.2.0/grid/bin

./srvctl stop database -d gddb -o immediate

 

2.用srvctl config vip 檢查vip設定

 

$ srvctl config vip -n p570a

VIP exists.:p570a

VIP exists.: /p570a-vip/192.168.128.12/255.255.255.0/eth0

$ srvctl config vip -n p570b

VIP exists.:p570b

VIP exists.: /p570b-vip/192.168.128.13/255.255.255.0/eth0

 

3.停止vip 服務和修改vip

 

./srvctl stop listener -n p570a

./srvctl stop listener -n p570b

./srvctl stop vip -n p570a

./srvctl stop vip -n p570b

./srvctl modify nodeapps -n p570a -A 10.76.31.113/255.255.255.0/en0

./srvctl modify nodeapps -n p570b -A 10.76.31.115/255.255.255.0/en0

 

4.確認是否修改成功

 

./srvctl config vip -n p570a

VIP exists.:p570a

VIP exists.:/p570a-vip/10.76.31.113/255.255.255.0/en0

./srvctl config vip -n p570b

VIP exists.:p570b

VIP exists.:/p570b-vip/10.76.31.115/255.255.255.0/en0

         

5.啟動vip服務,監聽，資料庫

./srvctl start vip -n p570a

./srvctl start vip -n p570b

./srvctl start listener -n p570a

./srvctl start listener -n p570b

./srvctl start database –d gddb

 

修改成功
