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.
