RAC: TCP.VALIDNODE_CHECKING Failing after Listener Reload (Doc ID 2109789.1)

Last updated on FEBRUARY 28, 2019

Applies to:

Oracle Net Services - Version to [Release 12.1]
Information in this document applies to any platform.


In a GRID or RAC environment where TCP.VALIDNODE_CHECKING is enabled, please be aware that any change to the TCP.INVITED_NODES or TCP.EXCLUDED_NODES
parameters would require a complete stop and start of the VIP listeners. 

The LSNRCTL reload command after a change to TCP.INVITED_NODES is breaking the TCP.VALIDNODE feature.  See <BUG:22194469> TCP.INVITED_NODES is Disabled after LSNRCTL Reload

This behavior does not impact the SCAN listeners and does not seem to be present when running a local listener in RDBMS_HOME.  (Versus GRID)



Change to the sqlnet.ora file setting for:  TCP.INVITED_NODES in $ORACLE_HOME/network/admin/sqlnet.ora in GRID_HOME.
