本文转自ITPUB上一兄弟总结，以备查询。

今天一早来，同事说他周末在安装 rac 出问题了，始终无法使用vipca 创建 vip资源 ， 叫我帮忙看看。

他用的是 vmware server 2.0 搭建 虚拟 rac 。

一. 环境如下　
OS: Red Hat Enterprise Linux Server release 5.4 (Tikanga)
KERNEL : 2.6.18-164.el5
clusterware： clusterware 10.2.0.1


1. 我首先查看了他的 $ORA_CRS_HOME/bin 下的 vipca 文件, 是否消除 LD_ASSUME_KERNEL 。
    一看，果然没有消除。
    于是 export LD_ASSUME_KERNEL 的后一行 添加 unset LD_ASSUME_KERNEL  ，后保存 。

2. 再次执行 vipca ，但还是无法执行 报错，于是到 $ORA_CRS_HOME/cfgtoollogs/vipca/ 下查看日志 。
vipca.log

看了一会，发现其中 OCR does not have any global interfaces set 这个提示。
于是我怀疑是他的网络设置问题。

3. 用 设置网络，解决问题。
用oifcfg  查看的他网络
[root@node1 db]# oifcfg getif ;
没有显示信息，证明他的网络根本没设置好。

在查看 /etc/hosts
# The public network address for rac node1 and node2 .
192.168.100.101  node1  # --> n1
192.168.100.102  node2  # --> n2
# The private network address for rac n1 and n2 .
10.10.10.11     node1-priv #--> n1
10.10.10.12     node2-priv #--> n2
# The virtral network address for rac n1 and n2 .
192.168.100.41   node1-vip
192.168.100.42   node2-vip

添加网络
[root@node1 db]# oifcfg iflist
eth0  192.168.100.0
eth1  10.10.10.0
eth2  172.24.121.128
[root@node1 db]# oifcfg setif -global eth0/192.168.100.0ublic
[root@node1 db]# oifcfg setif -global eth0/10.10.10.0:cluster_interconnect
[root@node1 db]# oifcfg getif
eth0  192.168.100.0  global  public
eth1  10.10.10.0  global  cluster_interconnect

再次执行 vipca 成功。
