Cause of the Problem
The problem happened due to incorrect settings of /etc/hosts file or host user is unable to read the /etc/hosts file. TNS Listener fails while attempting to initiate subscription to ONS node down event.

Solution of the Problem
1) Verify that OS user has permission on /etc/hosts file.
$ls -l /etc/hosts

2) Verify that the /etc/hosts file contains the localhost entry in the following form:

127.0.0.1 localhost.localdomain localhost
10.1.10.2 myhost.arjudba.blogspot.com myhost

3) If you are not in RAC environment explicitly disable the 10g TNS Listener's subscription to ONS by editing the listener.ora file and add the parameter below in the listener.ora file.

SUBSCRIBE_FOR_NODE_DOWN_EVENT_{listener_name}=OFF

where {listener_name} would be replaced with the actual listener name configured in the listener.ora file.

For example, if the listener name is LISTENER (which is default listener), the parameter would be:

SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF

4) Start the listener.
$ lsnrctl start
