After verifying the Oracle Database installation, create the Oracle databases that you require.
If you are using Oracle Database without standby databases, perform the procedure How to Create a Primary Oracle Database.
If you are using Oracle Data Guard, create the following database instances:
Primary database instance. For instructions for creating a primary database, see How to Create a Primary Oracle Database.
Standby database instances. A standby database instance can be either a physical standby database instance or a logical standby database instance. For instructions for creating standby database instances, see your Oracle Database documentation.
