Create Database Template Using DBCA.
Now we are creating a template of existing database named "oradba" by using DBCA.
After the Template creation is complete copy all the files starting with "ORADBA" from the"{ORACLE_HOME}/assistants/dbca/templates/" directory to the"{ORACLE_HOME}/assistants/dbca/templates/" of any one RAC node.
After Doing that enable user equivalence as the ORACLE user on the node from which thedatabase installation is to be done.
Run DBCA now.
