CVU

Oracle10gR2新增了一个工具-Cluster Verification Utiltiy (cluvfy)，用以在部署RAC环境的不同阶段进行环境及所有重要组件的检查。

　　这个工具随Oracle10gR2发布，但是也可以被用于Oracle10gR1。

　　CVU所检查的范围非常广泛，涉及从初始的硬件安装到安装完成以及所有中间阶段的组建安装及配置。

　　但是cluvfy只对安装阶段及组件进行检查验证，不涉及调整、监控已经Cluster内在状况检查。

　　直接键入cluvfy可以获得提示输出:

　　[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选项可以对不同安装阶段进行环境及pre、post检查:

　　[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选项进行组件检查:

　　[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进行crsinst post安装检查:

　　[oracle@raclinux1 bin]$ cluvfy stage -post crsinst -n raclinux1
