将Oracle 10g RAC 1的vip由192.168.2.11改为192.168.2.13，rac2的vip由192.168.2.12改为192.168.2.14.
将Oracle 10g RAC 1的vip由192.168.2.11改为192.168.2.13，rac2的vip由192.168.2.12改为192.168.2.14.
一、软硬件环境概述在虚拟机VMware GSX Server上安装两套redhet Enterprise-R4-U4系统rac1和rac2，虚拟共享存储，， 在此基础上搭建的oracle10g RAC环境。
1、 rac1两块网卡eth0：192.168.2.111，eth1：10.10.10.11
2、 rac2两块网卡eth0：192.168.2.112，eth1：10.10.10.12
/etc/hosts文件:
127.0.0.1
localhost
192.168.2.111
rac1.mycorpdomain.com
rac1
192.168.2.11
rac1-vip.mycorpdomain.com
rac1-vip
10.10.10.11
rac1-priv.mycorpdomain.com
rac1-priv
192.168.2.112
rac2.mycorpdomain.com
rac2
192.168.2.12
rac2-vip.mycorpdomain.com
rac2-vip
10.10.10.12
rac2-priv.mycorpdomain.com
rac2-priv
三、更改VIP 1、确认当前rac1和rac2的vip配置
#./srvctl config nodeapps –n rac1 –a
VIP exists.:/rac1-vip.mycorpdomain.com/192.168.2.11/255.255.255.0/eth0
#./srvctl config nodeapps –n rac2 –a
VIP exists.:/rac2-vip.mycorpdomain.com/192.168.2.12/255.255.255.0/eth0
2、在rac1上停依赖于vip的资源
#cd /u01/app/oracle/product/10.2.0/crs_1/bin
停数据库实例
#./srvctl stop instance –d devdb –i ora.devdb.devd1.inst
停数据库
#./srvctl stop database –d devdb
停ASM实例
#./srvctl stop asm –n rac1
停vip，gsd，listener，ons
#./srvctl stop nodeapps –n rac1
3、在rac2上停依赖于vip的资源
#cd /u01/app/oracle/product/10.2.0/crs_1/bin
停数据库实例
#./srvctl stop instance –d devdb –i ora.devdb.devd2.inst
停数据库
#./srvctl stop database –d devdb
停ASM实例
#./srvctl stop asm –n rac2
#./srvctl stop nodeapps –n rac2
4、更改hosts文件
127.0.0.1
localhost
192.168.2.111
rac1.mycorpdomain.com
rac1
192.168.2.13
rac1-vip.mycorpdomain.com
rac1-vip
10.10.10.11
rac1-priv.mycorpdomain.com
rac1-priv
192.168.2.112
rac2.mycorpdomain.com
rac2
192.168.2.14
rac2-vip.mycorpdomain.com
rac2-vip
10.10.10.12
rac2-priv.mycorpdomain.com
rac2-priv
