11.5.5.1 About the CVU Grid Upgrade Validation Command Options

You can use the Cluster Verification Utility (CVU) to validate your system readiness before upgrading.

You can run upgrade validations in one of two ways:

• Run the installer, and allow the CVU validation built into the installer to perform system checks

• Run the CVU manual script cluvfy.bat script to perform system checks

To use the installer to perform pre-install checks, run the installation as you normally would. The installer starts CVU, and performs system checks as part of the installation process. Selecting the installer to perform these checks is particularly appropriate if you think you have completed preinstallation checks, and you want to confirm that your system configuration meets minimum requirements for installation.

To use the cluvfy.bat command-line script for CVU, navigate to the new Grid home where you extracted the image files for upgrade, that contains the runcluvfy.bat script, and run the following command to check the readiness of your Oracle Clusterware installation for upgrades:

runcluvfy.bat stage -pre crsinst -upgrade

Running runcluvfy.bat with the -pre crsinst -upgrade options performs system checks to confirm if the cluster is in a correct state for upgrading from an existing clusterware installation.

The runcluvfy command uses the following syntax, where variable content is indicated by italics:

runcluvfy.bat stage -pre crsinst -upgrade [-rolling] -src_crshome src_Gridhome
 -dest_crshome dest_Gridhome -dest_version dest_release
[-verbose]

The options are:

• -rolling

  Use this option to verify readiness for rolling upgrades.

• -src_crshome src_Gridhome

  Use this option to indicate the location of the source Oracle Clusterware or Grid home that you are upgrading, where src_Gridhome is the path to the home to upgrade.

• -dest_crshome dest_Gridhome

  Use this option to indicate the location of the upgrade Grid home, where dest_Gridhome is the path to the Grid home.

• -dest_version dest_release

  Use the dest_version option to indicate the release number of the upgrade, including any patchset. The release number must include the five digits designating the release to the level of the platform-specific patch. For example: 12.1.0.1.0.

• -verbose

  Use the -verbose option to produce detailed output of individual checks.
