What is the Cluster Verification Utiltiy (cluvfy)?
The Cluster Verification Utility (CVU) is a validation tool that you can use to check all the important components that need to be verified at different stages of deployment in a RAC environment. The wide domain of deployment of CVU ranges from initial hardware setup through fully operational cluster for RAC deployment and covers all the intermediate stages of installation and configuration of various components. Cluvfy does not take any corrective action following the failure of a verification task, does not enter into areas of performance tuning or monitoring, does not perform any cluster or RAC operation, and does not attempt to verify the internals of cluster database or cluster elements.
