ORA-24550 error in application (for example BMC control M) on an oracle db with standby and service setup

Cause: You might have a service based db connection confguration, but the service isnt started in db.

Fix: Start the service with which the app connects using dbms_service.start_service('<service_name>'); to start the service. Once service is started, retry the application start (for ex. BMC control M), the services should come up fine.
