ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA
Cause: The listener was not configured with a default service and SERVICE_NAME was missing from the CONNECT_DATA received by the listener.
Action: Possible solutions are:

- Configure DEFAULT_SERVICE parameter in LISTENER.ORA with a valid service name. Reload the listener parameter file using reload [<listener_name>]. This should be done by the LISTENER administrator.

- If using a service name, Check that the connect descriptor corresponding to the service name in TNSNAMES.ORA has a SERVICE_NAME or SID component in the CONNECT_DATA.
