"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 .
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.
