Multiple Listeners

I have a development box (UNIX) with 8.1.7.4 databases running. I just created a new oracle home for 10.2. Installed the software and migrated a database.

I can't get the 10.2 listener started. Everytime I try to start it with my ORACLE_HOME as the 10.2 home it tells me that LISTENER is already running. That is the name of the 8.1.7 listener.

Here is my 10.2 listener.ora contents:

LISTENER10 =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=myserv.us.hsbc)(PORT=1521))
(ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

#SID_LIST_
# List of services the listener knows about and can connect
# clients to. There is no default. See the Net8 Administrator's
# Guide for more information.
#
SID_LIST_LISTENER10=
(SID_LIST=
(SID_DESC=
#BEQUEATH CONFIG
(GLOBAL_DBNAME=PHTEST)
(SID_NAME=PHTEST)
(ORACLE_HOME=/orahome1)
#PRESPAWN CONFIG
(PRESPAWN_MAX=20)
(PRESPAWN_LIST=
(PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
)
)
)


Your help would be approciated.

thanks

You need to change the default port (1521) to another unused port.

are they both on the same port?

why not use the 10g listener to service the 8i databae?
