However, to answer the question, you need to name the listeners something other then listener and you need to have them listening on different ports. When you use the lsnrctl command you have to reference the listener you are dealing with.

There are reasons to have multiple listeners. For example, when running HP ServiceGuard I have setup the databases to be able to fail separately so they
each have their own listener that fails with the database. I needed it with Trusted Oracle as well, but I believe that is case dependant. On listened for stuff coming from the secret side and the other from the other side.

Edward,

One must ask, what benefit do you perceive you will obtain from having multiple listeners? The listener is only there to hear the end applications request for database service and pass them along to the appropriate dedicated
server or dispatcher as required. Then it goes off to do other things. We have
one HP with 9 different instances, one listener. Works fine all day.

Hello All,

I am currently running Oracle 816 64bit on a Solaris 8 box. I have three databases on the system with one LISTENER for all of them. Is it possible to configure multiple listeners, one for each database? We have tried in the past with no success... If there is a document on the web somebody could point me to, that would be great! I have searched for one but must not be searching correctly.

TIA,
