-- 使用 runcluvfy 校验Oracle RAC安装环境

--*****************************************

    所谓工欲善其事，必先利其器。安装 Orale RAC 可谓是一个浩大的工程，尤其是没有做好前期的规划与配置工作时将导致安装的复杂

度绝非想象。幸好有runcluvfy工具，这大大简化了安装工作。下面的演示是基于安装Oracle 10g RAC / Linux来完成的。

1.从安装文件路径下使用runcluvfy实施安装前的校验

    [oracle@node1 cluvfy]$ pwd

    /u01/Clusterware/clusterware/cluvfy

    [oracle@node1 cluvfy]$ ./runcluvfy.sh stage -pre crsinst -n node1,node2 -verbose

    Performing pre-checks for cluster services setup

    Checking node reachability...

    信息，这是一个bug，Metalink中有详细说明，doc.id:338924.1。参考本文尾部列出的内容。

    对于上面描述的failed的包，尽可能的将其安装到系统。

2.安装Clusterware 后的检查,注意，此时执行的cluvfy是位于已安装的路径
