处理办法：
1、加入unset LD_ASSUME_KERNEL <<<== Line to be added
操作例如以下：
/u01/product/crs/bin vi vipca if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ] then LD_ASSUME_KERNEL=2.4.19 export LD_ASSUME_KERNEL fi unset LD_ASSUME_KERNEL <<<== Line to be added
2、设置ip：
root@rac2 bin]# ./oifcfg getif [root@rac2 bin]# ./oifcfg setif -global eth0/192.168.10.0:public [root@rac2 bin]# ./oifcfg setif -global eth1/192.168.20.0:cluster_interconnect [root@rac2 bin]# ./oifcfg getif eth0 192.168.10.0 global public eth1 192.168.20.0 global cluster_interconnect
在oui运行vipca命令，（注意在root下）
[root@rac2 bin]# ./vipca
须要把两个节点都加入进去，然后填写vip地址
./crs_stat -t
