Oracle10gR2新增了一個工具-Cluster Verification Utiltiy (cluvfy)，用以在部署RAC環境的不同階段進行環境及所有重要組件的檢查。
這個工具隨Oracle10gR2發布，但是也可以被用于Oracle10gR1。
CVU所檢查的范圍非常廣泛，涉及從初始的硬件安裝到安裝完成以及所有中間階段的組建安裝及配置。
但是cluvfy只對安裝階段及組件進行檢查驗證，不涉及調整、監控已經Cluster內在狀況檢查。
直接鍵入cluvfy可以獲得提示輸出:
[oracle@raclinux1 bin]$ cluvfy
USAGE:
cluvfy [ -help ]
cluvfy stage { -list -help }
cluvfy stage {-PRe-post} [-verbose]
cluvfy comp { -list -help }
cluvfy comp [-verbose]
使用stage選項可以對不同安裝階段進行環境及pre、post檢查:
[oracle@raclinux1 bin]$ cluvfy stage -list
USAGE:
cluvfy stage {-pre-post} [-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
使用comp選項進行組件檢查:
[oracle@raclinux1 bin]$ cluvfy comp -list
USAGE:
cluvfy comp [-verbose]
Valid components are:
nodereach : checks reachability between nodes
nodecon : checks node connectivity
cfs : checks CFS integrity
ssa : checks shared storage accessibility
space : checks space availability
sys : checks minimum system requirements
clu : checks cluster integrity
clumgr : checks cluster manager integrity
ocr : checks OCR integrity
crs : checks CRS integrity
nodeapp : checks node applications existence
admprv : checks administrative privileges
peer : compares properties with peers
使用cluvfy進行crsinst post安裝檢查:
[oracle@raclinux1 bin]$ cluvfy stage -post crsinst -n raclinux1
