10gRAC系列之cluvfy用法及驗證錯誤解決

在安裝Oracle10g RAC之前，可以通過Oracle提供的一個工具進行cluster環境驗證，這個工具叫做cluvfy。

cluvfy常用的命令有如下一些，通過這些命令可以對CRS或INSTANCE的安裝需求進行驗證:

bash-2.05$ cluvfy -help     

USAGE:
cluvfy [ -help ]
cluvfy stage { -list | -help }
cluvfy stage {-pre|-post} <stage-name> <stage-specific options>  [-verbose]
cluvfy comp  { -list | -help }
cluvfy comp  <component-name> <component-specific options>  [-verbose]

但是在Solaris系統下運行這個命令經常會遇到如下一個錯誤:

bash-2.05$ cluvfy stage -pre crsinst -n db210-rac2

ERROR:
Unable to retrIEve database release version.
Verification cannot proceed.

這個錯誤主要是因為由於環境變量的設置，cluvfy無法找到相應的類庫所致。
只需要修改用戶環境變量.profile文件中的LD_LIBRARY_PATH_64即可,在使用了EMC的環境中，缺省的該參數可能具有如下設置:

bash-2.05$ env|grep 64
LD_LIBRARY_PATH_64=/opt/EMCpower/lib/sparcv9

在該變量中增加了$ORA_CRS_HOME/lib即可，我的環境設置如下:

bash-2.05$ env|grep 64
LD_LIBRARY_PATH_64=/opt/EMCpower/lib/sparcv9:/opt/Oracle/product/10.2.0/Crs10g/lib

現在就可以通過cluvfy進行環境檢查:

bash-2.05$ cluvfy stage -pre crsinst -n db210-rac1,db210-rac2

在進行了相應的調整後，滿足了系統要求，就可以安裝Oracle10g CRS和RAC環境了。
