用srvctl modify nodeapps命令更改vip地址

     Modify the VIP or VIP Hostname for a 10g Oracle Clusterware,有時候我們可能需要修改vip地址或對應的vip

主機名,而我這次在安裝rac過程中,執行vipca時,把私有IP當成VIP來使用,導致在啟動vip服務時啟動不了

hosts裡面內容如下:

[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安裝過程中日誌提示

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

從metalink上找到一篇文章,可以用srvctl工具來修改vip地址的,下面是具體測試過程

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

可以看到vip地址已經修改成功。
