用srvctl modify nodeapps命令更改vip地址

原创 Linux操作系统 作者:paulyibinyi 时间:2009-05-31 15:04:14 0 删除 编辑

     Modify the VIP or VIP Hostname for a 10g Oracle Clusterware,有时候我们可能需要修改vip地址或对应的vip

主机名,而我这次在安装rac过程中,运行vipca时,把私有IP当成VIP来使用,导致在启动vip服务时启动不了

hosts里面内容如下:

[oracle@RAC1 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost
138.30.0.101            rac1
138.30.0.102            rac2
138.30.0.201            rac1-vip
138.30.0.202            rac2-vip

100.100.1.1             rac1-priv
100.100.1.2             rac2-priv

在vipca安装过程中日志提示

2009-05-31 14:33:44.212: [    RACG][3067446976] [2411][3067446976][ora.rac1.vip]: IP:100.100.1.1 is already up in the network (host=RAC1)

[oracle@RAC1 ~]$ crs_stat -t
Name           Type           Target    State     Host       
------------------------------------------------------------
ora.rac1.gsd   application    ONLINE    ONLINE    rac1

ora.rac2.ons   application    ONLINE    ONLINE    rac2       
ora.rac2.vip   application    ONLINE    OFFLINE      

可以看到vip服务资源offline

从metalink上找到一篇文章,可以用srvctl工具来修改vip地址的,下面是具体测试过程

Changing VIP Addresses
Use the following procedure to change a VIP address:
1. Stop all database and ASM instances.
2. Stop the Listeners, and node applications using the srvctl stop nodeapps
command.
3. Run the following command to verify node connectivity between all of the nodes
for which your cluster is configured. This command discovers all of the network
interfaces available on the cluster nodes and verifies the connectivity between all
of the nodes by way of the discovered interfaces. This command also lists all of the
interfaces available on the nodes which are suitable for use as VIPs.
cluvfy comp nodecon -n all [-verbose]
4. Run the srvctl modify nodeapps command with the -A option as described
in Appendix E. Use the crs_stat command to identify all active node
applications.
5. Restart all of the instances and node applications that you stopped in Step 1 and 2.

[oracle@RAC1 ~]$ srvctl stop nodeapps -n rac1

[oracle@RAC1 ~]$ srvctl stop nodeapps -n rac2

[root@RAC1 bin]# ./srvctl modify nodeapps -n rac1 -A 138.30.0.201/255.255.255.0/eth0
[root@RAC1 bin]# ./srvctl modify nodeapps -n rac2 -A 138.30.0.202/255.255.255.0/eth0

[root@RAC1 bin]# su - oracle
[oracle@RAC1 ~]$ crs_stat -t

可以看到vip地址已经修改成功。
