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.
