11G GRID 安装缺少到libcap.so.1而终止的解决方法

在OEL 6.3上搭建一台11G的RAC测试环境，在最后执行root.sh脚本的时候遇到libcap.so.1: cannot open shared object file: No such file or directory 错误。


如下所示：


[root@rac1 11.2.0]# /g01/oraInventory/orainstRoot.sh
Changing permissions of /g01/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.


Changing groupname of /g01/oraInventory to oinstall.
The execution of the script is complete.

查询了一下，发现是由于缺少包导致的。


在2个节点上重新安装上此包。

再次执行root.sh脚本，又遇到了ohasd failed to start at /g01/app/11.2.0/grid/crs/install/rootcrs.pl line 443 错误。

网上搜了一下，竟然是ORACLE 的BUG。
解决方法竟然是出现pa user cert的时候在另一个窗口不停的执行下面的命令，直到命令执行成功，真是变态啊。
