It's pretty straightforward, pretty much the same as configuring remote listeners for RAC, just add additional address entries in the local listener definition, one for each port.

The requirement is that 4 applications/users will be configured to use different listeners/ports and I must be able to bring down one listener/port and the others will still be able to function. I read oracle support note 1585786.1 (Note 5 on Adding additional node listeners to the system using different ports) which suggests to add a node listener on a different port and set the local listener. If i set local_listener to use port 1522 (lets assume current is 1521) and register the database with the listener on port 1522, will i still be able to connect to 1521? And can i do this for 4 listeners and be able to achieve my requirement. Many thanks for your time and help. Appreciate it.
