B.Create a database service on the primary database that is started automatically by a trigger, when the database role is PRIMARY, modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.
C.Set the INSTANCE_NAME parameter identically on all databases; modify the connection descriptor on client applications to include all the standby hosts and connect to the database instance using that service name.
D.Set the DB_NAME and DB_UNIQUE_NAME identical on all databases, modify the connection descriptors on client applications to include all the standby hosts and connect to the database using that service name.
