使用Cluster Verify Utility校验RAC环境

The Cluster Verification Utility (CVU) is a utility distributed with Oracle Grid Infrastructure / Oracle Clusterware. It was developed to assist in the installation and configuration of Oracle Clusterware as well as Oracle Real Application Clusters (RAC). CVU checks range from initial hardware setup tests through entire cluster checks for Oracle RAC deployments. CVU covers all intermediate stages during the installation and configuration of a complete Oracle RAC stack.
