在linux 5上装10G RAC时，常常会碰到“libpthread.so.0: cannot open shared object file"这个报错的，这个报错是由于无法使用vipca导致的。 该报错有以下两种解决方案：
方法1
不去理会，选择继续，然后安装10.2.0.4及以上版本的patchsets，然后在来手工执行vipca完成vip配置工作，因为这个错误在10.2.0.4版本中已经得到修复
方法2

手工配置
确认网络配置
# ./oifcfg getif
eth0 172.21.1.0 global public
eth1 10.10.10.0 global cluster_interconnect
# ./oifcfg iflist
eth0 172.21.1.0
eth1 10.10.10.0
如果不正确可以使用下列命令配置
# ./oifcfg setif -global eth0/172.21.1.0:public
# ./oifcfg setif -global eth1/10.10.10.0:cluster_interconnect
然后修改vipca和srvctl ，搜索LD_ASSUME_KERNEL,注释掉下列几行
arch='uname -m'
#?????? if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ]
#?????? then
#??????????? LD_ASSUME_KERNEL=2.4.19
#??????????? export LD_ASSUME_KERNEL
#?????? fi
再执行./vipca即可，二者原理相同
关于这个报错，Oracle有以下文档进行说明

When installing 10gR2 RAC on Oracle Enterprise Linux 5 or RHEL5 or SLES10 there are three issues that users must be aware of.

Issue#1 : To install 10gR2, you must first install the base release, which is 10.2.0.1. As these version of OS are newer, you should use the following command to invoke the installer:

$ runInstaller -ignoreSysPrereqs??????? // This will bypass the OS check //

Issue#2 :? At end of root.sh on the last node?vipca will fail to run with the following error:
