⟩ ORA-12509 TNSlistener failed to redirect client to service handler?

Cause: The dispatcher terminated unexpectedly

Action: Attempt to connect again and if the same error

occurs, contact the DBA to check the state of the

dispatchers for this SID. If the problem persists, turn on

tracing in the listener to determine the TNS error caused by

the redirect.
