更改VIP 地址
1. 确定用于支持VIP 的接口：
#ifconfig -a
[root@jyrac2 ~]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:0C:29:69:BC:16
inet addr:192.168.1.204 Bcast:192.168.1.255 Mask:255.255.255.0

2. 停止依赖VIP 的所有资源：
$ srvctl stop instance -d DB -i DB1 $ srvctl stop asm -n node1 $ srvctl stop nodeapps -n node1 [oracle@jyrac2 crs]$ cd /u01/app/oracle/product/10.2.0/crs/bin [oracle@jyrac2 bin]$ ./srvctl stop instance -d jyrac -i jyrac2 [oracle@jyrac2 bin]$ ./srvctl stop asm -n jyrac2 [oracle@jyrac2 bin]$ ./srvctl stop nodeapps -n jyrac2
3. 验证VIP 不再处于运行状态：
$ ifconfig -a [ + $ crs_stat
[root@jyrac2 ~]# ifconfig -a

[oracle@jyrac1 bin]$
从上面的输出可以看出实例jyrac2已经停止运行节点jyrac2的vip已经停止了
4. 更改/etc/hosts 中的IP 和DNS。
对所有节点进行修改将jyrac2节点的vip从192.168.1.206修改为192.168.1.216
[root@jyrac2 ~]# vi /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 jyrac2 localhost.localdomain localhost 192.168.1.201 jyrac1 192.168.1.204 jyrac2 192.168.1.202 jyrac1-priv 192.168.1.205 jyrac2-priv 192.168.1.203 jyrac1-vip 192.168.1.216 jyrac2-vip [root@jyrac1 ~]# vi /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 jyrac1 localhost.localdomain localhost 192.168.1.201 jyrac1 192.168.1.204 jyrac2 192.168.1.202 jyrac1-priv 192.168.1.205 jyrac2-priv 192.168.1.203 jyrac1-vip 192.168.1.216 jyrac2-vip
5. 使用srvctl 修改VIP 地址：
修改nodeapps 并提供新的虚拟IP 地址。使用带有–A 选项的srvctl modify
nodeapps 命令。应以root 用户身份运行此命令。在本幻灯片的示例中，依次指定
了新IP 地址(192.168.1.216)、相应的网络掩码(255.255.255.0) 以及希望VIP
使用的接口(eth0)。
[root@jyrac2 ~]# cd /u01/app/oracle/product/10.2.0/crs/bin [root@jyrac2 bin]# ./srvctl modify nodeapps -n jyrac2 -A 192.168.1.216/255.255.255.0/eth0 You have new mail in /var/spool/mail/root [root@jyrac2 bin]#
6. 启动nodeapps 及依赖它的所有资源：
# srvctl start nodeapps -n node1 [oracle@jyrac2 bin]$ ./srvctl start nodeapps -n jyrac2 [oracle@jyrac2 bin]$ ./srvctl start asm -n jyrac2 [oracle@jyrac2 bin]$ ./srvctl start instance -d jyrac -i jyrac2
7. 对集群中的所有节点重复上述步骤。由于srvctl 是集群范围的管理工具，因此可以
与第一个节点保持连接。
注：如果只更改了IP 地址，并且listener.ora、tnsnames.ora 和初始化参数文件使
用的是虚拟主机名，则无需对这些文件进行更改。如果同时更改了节点的虚拟主机名和
VIP 地址，则需要用新的虚拟主机名修改这些文件。对于listener.ora 文件，可以使
用netca 来删除旧监听程序并创建一个新监听程序。此外，还需要对连接到旧虚拟主机名
的所有客户机的tnsnames.ora 文件进行更改。
