One more to Daniel's list. Are you using MTS (multi thread server)? If so, the dispatcher(s) will be using different ports, e.g. (ADDRESS=(PROTOCOL=tcp)(HOST=foo)(PORT=61686))

Finally, how do you know that the Oracle listener is indeed using TCP port 9090. How do you determine that? What proof do you have?

Not that I'm calling you a liar, but one needs to be absolutely sure that the problem is correctly identified before trying to fix it. :-)

The listener is not in the habit of using a port that you did not specify in the listener.ora configuation file.
