oracle 11gR2 如何修改vip

因为业务需要，需要将p570a主机和p570b主机上的vip做修改

修改前ip

192.168.128.12   p570a-vip

192.168.128.13   p570b-vip

修改后ip

10.76.31.113   p570a-vip

10.76.31.115   p570b-vip

两个节点的/etc/hosts 文件要修改为修改后的vip

以下为具体步骤：

1.关闭database

root用户下运行以下命令

cd /grid/app/11.2.0/grid/bin

./srvctl stop database -d gddb -o immediate

2.用srvctl config vip 检查vip设置

$ 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 服务和修改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.确认是否修改成功

./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.启动vip服务,监听，数据库

./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
