I am running oracle 11.2.3 and we have a server with multiple instances running. All of them are registered to port 1521 with the default listener. Now we are required to make one instance available on a new port. I was wondering if there is a way to add a new listener to a new port and restrict it to register only one instance so that this listener can not make connections for other instances.
Current Listener Configuration:
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521)) ) ) )
