RE: Any way to run more than listener on the same port?

I am copy/pasting this from the archives:

Yes you can have multiple listeners listening on different VIPs on the
same port.

To configure, just edit your listener.ora file and edit the
ADDRESS_LIST part of each listener definition, and set your
"HOST=<ip>" to the VIPs that your administrators are giving.

Example listener.ora:
LISTENER_DB1 =
  (ADDRESS_LIST =
        (ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY1))
        (ADDRESS= (PROTOCOL= TCP)(Host= 10.5.5.1)(Port= 1521))
  )

LISTENER_DB2 =
  (ADDRESS_LIST =
        (ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY2))
        (ADDRESS= (PROTOCOL= TCP)(Host= 10.5.5.2)(Port= 1521))
  )

LISTENER_DB3 =
  (ADDRESS_LIST =
        (ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY3))
        (ADDRESS= (PROTOCOL= TCP)(Host= 10.5.5.3)(Port= 1521))
  )


But with dynamic registration you dont really need to do "1 listener
per database". You can have 1 listener listen on all ips, and let each
database register with the listener as it starts/stops.
