Subscription For Node Down Event Still Pending

Today I saw the next warnning into a listener log file constantly;

‘WARNING: Subscription for node down event still pending’

This error is related to the Oracle TNS Listener’s default subscription to the Oracle Notification Service (ONS). In non-RAC architecture it’s recommende switch off this functionality.

Modify the listener.ora file with the next parameters;


After that you need restart or reload the listener.

For more information about this parameter, please take a look at 372959.1 ML/MOS note.
