Re: How to startup 2 listeners on the same machine?

There should be only One Listener.ora per ORACLE_HOME where you can define any number of Listeners either listening to multiple databases or to the Same Database. Multiple Listeners for One Database is used for Load Balancing.

It would be better to configure them to run on different TCP Ports. The Default listener is called 'LISTENER ' which is started using lsnrctl start (or)
lsnrctl start LISTENER

Any Other Listener will be started using lsnrctl start New_Listener

Hope this helps,
