Today, I will talk to you about the use of the cluster verification tool cluvfy, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Cluvfy, as a cluster verification tool, can play a very good auxiliary role in the installation and configuration of Oracle clusters and RAC. Take a brief look at the functions brought to us by this tool.

1. Get help for the cluster verification tool cluvfy

RACDB1@rac1 / home/oracle$ cluvfy-help

USAGE:

Cluvfy [- help]

Cluvfy stage {- list |-help}

Cluvfy stage {- pre |-post} [- verbose]

Cluvfy comp {- list |-help}

Cluvfy comp [- verbose]

This article mainly introduces the verification methods of stage types.

Each phase of the Oracle cluster and RAC installation process is called a stage and should be checked before and after entering each stage. Before entering a specific stage, a series of predefined content checks should be carried out to ensure that the cluster environment meets the conditions for moving on to the next phase, the so-called "pre-checking". Corresponding to this is the "post-check", that is, a set of predefined check actions that need to be performed after the completion of a certain stage of operation.

two。 Get verifiable information about the stage option

You can use the "cluvfy stage-list" command to get a verifiable phase.

RACDB1@rac1 / home/oracle$ 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

Simple comments:

-post hwos: post-check the hardware and operating system

-pre cfs: pre-check the CFS setting

-post cfs: post-check the CFS settings

-pre crsinst: pre-check the CRS installation

-post crsinst: post-check the CRS installation

-pre dbinst: pre-check the database installation

-pre dbcfg: pre-check the database configuration.
