Is anyone else out there running both a 10.2 and a 9.2 listener on the same port?

The only way you can run any two listeners on the same port is if they have different IP addresses. The pair of (IP address, port number) is subject to a uniqueness constraint for listening, in most modern operation systems.

Previously I was running 3 listeners on the same port with no problems (2 of them 9.2 one of them 10.1). When I try to start the listener for the 10.2 database it complains that there is already a listener running on that port:


That would most likely be your 10.1 listener.


I'm using the same host and key settings that worked on the 10.1 instance:


More circumstantial evidence.

The "netstat" command, run with root privilege, under most versions of Unix will give you more clues as to which programs are listening on which ports.
