These messages are related to the Oracle TNS Listener's default subscription to the Oracle Notification Service (ONS). In a non-RAC environment it is recommended to disable this subscription.   This feature was introduced in Oracle 10g. SOLUTION Set the following parameter in the listener.ora: SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name>=OFF Where <listener_name> should be replaced with the actual listener name configured in the LISTENER.ORA file. SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name> parameter is to be placed by itself on an empty line. It will be necessary to restart or reload the listener following the addition of this parameter. This will prevent the messages from being written to the log file and may also prevent the TNS Listener from hanging periodically.  See (10g only) NOTE 340091.1 Intermittent TNS Listener Hang, New Child Listener Process Forked Please Note: Setting SUBSCRIBE_FOR_NODE_DOWN_<listener_n

If you wish to enable DDL logging for your database by setting the parameter enable_ddl_logging to true , you must first license the Oracle Change Management Pack. If you set the enable_ddl_logging parameter to true, the instance will record the DDL changes in the log.xml file. If you don't set this parameter to true, Oracle won't record these changes to the log.xml or the alert log.
