Oracle技术之Oracle CLUVFY工具（二）
如果安装过10g以后的RAC环境，应该对这个工具并不陌生。在安装Cluster和Database之前通常会执行runcluvfy.sh脚本来检查当前系统是否满足安装条件。
这篇介绍stage相关选项。
可以通过stage �Clist来列出所有cluvfy工具支持的部署组件：
bash-2.03$ cluvfy stage -list
USAGE:
cluvfy stage {-pre|-post} <stage-name> <stage-specific options> [-verbose]
Valid stage options and stage names are:
-post hwos : post-check for hardware and operating system
-pre crsinst : pre-check for CRS installation
-post crsinst : post-check for CRS installation
-pre dbinst : pre-check for database installation
-pre dbcfg : pre-check for database configuration
其中-pre crsinst、-post crsinst和-pre dbinst都是RAC安装常用的验证选项：
bash-2.03$ cluvfy stage -pre crsinst -n racnode1,racnode2 -r 10gR2 -c /dev/rac/ocr -q /dev/rac/vot -osdba dba
