ORA-12516: TNS:listener could not find available handler with matching protocol stack
 *Cause: None of the known and available service handlers for the given
 SERVICE_NAME support the client's protocol stack: transport, session,
 and presentation protocols.
 *Action: Check to make sure that the service handlers (e.g. dispatchers)
 for the given SERVICE_NAME are registered with the listener, are accepting
 connections, and that they are properly configured to support the desired
 protocols.

Regards
Michel
