WARNING: Subscription node down event still pending
Oracle Net Services - Version: 10.1.0.2 to 10.2.0.2
This problem can occur on any platform.
You are receiving the following warning messages in the listener.log file constantly since upgraded the TNS Listener from 126.96.36.199 to 10.2.0.2:
'WARNING: Subscription for node down event still pending'
Upgraded the TNS Listener from 10.2.0.2.0
These messages are related to the Oracle10g TNS Listener's default subscription to the Oracle Notification Service (ONS). In a non-RAC environment it is recommended to disable this subscription.
Set the following parameter in the listener.ora:
This will prevent the messages from being written to the log file, but also prevent the 10g TNS
Listener from hanging periodically.
Please Note: Setting SUBSCRIBE_FOR_NODE_DOWN_EVENT to OFF disable some RAC functionality. The above workaround is valid only for non-RAC environments.
The issue is present on all 10g versions.
