You have to first show your listener.ora and sqlnet.ora files, of course.

So the situation is as expected.
There is no static services on your new listener so no services in the output until some instances register some services to this listener.

Your listener.or file is corrupted: it has two entries for LISTENER. What did you do when you created my_listener? What tools did you use? I really believe that it is best not to touch listener.ora in a GI environment, other than to include an ifile directive pointing to a file that you can edit as much as you like.

--update: typo

I created my_listener by using the command NETCA.

I have never seen netca corrupt the file in this way. Is it the same on all nodes? Are you certain no-one has edited it by hand?

Set LOCAL_LISTENER to point to the new listener on the instances you want they register to this one.

Andy, I was interested in this problem because I have NEVER seen a listener.ora file corrupted in this way. It would have been interesting to see if the corruption has been propagated to the the other nodes. But if you are not bothered, then neither am I.
Michel has given you one solution to your immediate problem - though you might want to consider whether you would be better off using the SCAN in the way it is meant to be used.
