Oracle10gR2 New Feature:CVU(Cluster Verification Utiltiy)

« 太多的选择 | Blog首页 | Oracle9i新特点-如何修改Spfile的参数 »

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
