Listener Error "TNS-01189: The listener could not authenticate the user"
Good morning. We have a dual-homed (one home is 10.2.0.4 and the other is 10.2.0.5) server running a 10.2.0.5 listener. We accidentally applied the April2011 PSU to the 10.2.0.5 home without shutting down the listener. The PSU installed correctly but the listener now gives the error "TNS-01189: The listener could not authenticate the user" when any attempt is made to run the following lsnrctl commands: reload, stop, services, and status. When the start command is issued, it informs us the listener is already running (which is correct). The listener is working properly handing off database connections but we cannot administer it.
Would installing the PSU while the listener was running cause this problem? Any idea on how to reload the listener? We even went so far as to deinstall 10.2.0.5 on the server and reinstall it with a clean cloned copy of 10.2.0.5. We also tried to create a new listener (which it did) but would not start the new listener. It said one listener was already running.
From EM Grid Control, we can administer the listener (make basic changes to the listener.ora file) but we cannot stop the listener from EM Grid Control either. (Not a surprise.)
Ideas? Thoughts?
