All Java-based tools and utilities that are available in Oracle RAC are called by executing scripts of the same name as the tool or utility. This includes the Cluster Verification Utility (CVU), Database Configuration Assistant (DBCA), the Net Configuration Assistant (NETCA), Server Control Utility (SRVCTL), and the Global Services Daemon (GSD). For example to run DBCA, enter the command dbca.
