Symptoms

After enabling Valid Node Checking for a 2nd listener configuration in our listener.ora file, the listener will not start:

lsnrctl start <listener name> yields:

Starting /u01/app/oracle/product/11.2.0.4/bin/tnslsnr: please wait...
TNSLSNR for HPUX: Version 11.2.0.4.0 - Production TNS-01196: Listener failed to initialize valid node list

TNS-01196: Listener failed to initialize valid node list

NL-07001: Could not resolve the provided node name

A level 16 listener trace reveals the errors:

Changes

This is a new implementation of VALID_NODE_CHECKING_REGISTRATION_listener_name=ON.  The listener was previously started and running.
These errors occurred only  after adding the VNCR parameter setting to the listener.ora and then attempting to start the listener.
