【cluvfy】叢集驗證工具cluvfy使用方法——stage

531968912發表於2017-04-18

cluvfy作為叢集驗證工具在Oracle叢集和RAC安裝和配置的過程中可以起到非常好的輔助作用，簡單看一下這個工具帶給我們的功能。

1.獲取叢集驗證工具cluvfy的幫助資訊
RACDB1@rac1 /home/oracle$ 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]

本文主要介紹一下有關stage型別的驗證方法。

Oracle叢集和RAC安裝過程中每個階段都稱作一個stage，進入每一個stage之前和之後都應該做檢查。在進入特定階段之前應進行一系列的預定義內容的檢查，確保叢集環境已滿足進入下一階段的條件，即所謂的“預檢查”。與之對應的便是“後期檢查”，即在完成某個階段操作後需要執行的一組預定義的檢查動作。

2.獲得stage選項可驗證的資訊
可以使用“cluvfy stage -list”命令獲得可驗證的階段。
RACDB1@rac1 /home/oracle$ 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 cfs     : pre-check for CFS setup
        -post cfs     : post-check for CFS setup
        -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

簡單的註釋：
-post hwos：對硬體和作業系統進行後期檢查；
-pre cfs：對CFS設定進行預檢；
-post cfs：對CFS設定進行後期檢查；
-pre crsinst：對CRS安裝進行預檢查；
-post crsinst：對CRS安裝進行後期檢查；
-pre dbinst：對資料庫安裝進行預檢查；
-pre dbcfg：對資料庫配置進行預檢查。

4.小結
cluvfy工具的stage選項所檢驗的階段涵蓋了Oracle叢集和RAC安裝的每一個重要的步驟，建議在每一步驟完成之前和之後都應該使用cluvfy工具進行驗證。

Good luck.
