All listeners were working fine but suddenly they shows down with the following error:
Although a Listener with name "LISTENER", is running on this host at port: "nnnn", it was not started using this target's "LISTENER.ORA" file. CORRECTIVE ACTION: To monitor this "EM Listener Target" with its present configuration, you must stop the currently running listener process, and start it again using the Listener Parameter file: oracle_home/network/admin/listener.ora . Alternatively, you can update this target's "LISTENER.ORA Location" parameter with the location of the currently running Listener, which was started using:oracle_home/network/admin/listener.ora.
The following alert is sent:
The LISTENERNAME is down: LISTENERNAME not found in <directory>
