Description

On migration of remote listener from one node to another, for example during 
node eviction (failover), the database does not re-register with the listener 
as it does not receive any EOF. 
As a result the database keeps listening on the same socket when ideally
it should re-register. Rediscovery Notes Instance does not register 
services when scan fails over

  Workaround alter system set remote_listener = '';
 alter system set remote_listener = ':';





 Note: This fix is just one piece of a larger solution needing other fixes
 so that the clusterware / node monitor can trigger a re-register as
 required.
