Thanks Hans, I'll try Metalink.

Yes, Oracle port 1521 is used only for the initial connection and the
Listener will then inform your 'client process' and it's 'server process'
which port they should continue to use.

This is addressed by Oracle for some firewalls, and documented in the
Oracle
Networking documentation (Which, IIRC is Net8 for Oracle8i) as well as
Metalink. Suggest you check Metalink for certification with Westell. (At
one time searching on 'firewall' in Metalink would provide sufficient info
but I have not looked for a while.)

Not being familiar with this combo, it might be worth while
trying to set use_shared_socket=true in the environment.
It should make all connections going thru the listener port
socket (1521 in your case).

Ymmv!

Thanks Frank, I'll give that a try. Incidentally, I found a method using a
configuration file called cman.ora. I followed the instructions but it
didn't work in the Novell environment. I think that maybe it is for Unix.
The contents of the method is as follows... I hope it'll help someone else.

# Installation and configuration of CMAN

# The installation must be done on the server where the database is. After
the installation we need to start the services (cmctl start or in services)
# Configuration has two steps, configuration of server side and
configuration of client side. # Configuration of CMAN in server side # We
need to create the cman.ora file in $ORACLE_HOME\network\admin

# It could be like this:

CMAN = (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.254)(PORT=1 610))

CMAN_PROFILE=
(PARAMETER_LIST=
(MAXIMUM_RELAYS=70)
(LOG_LEVEL=0)
(TRACING=NO)
(RELAY_STATISTICS=NO)
(SHOW_TNS_INFO=NO)
(USE_ASYNC_CALL=NO)
(AUTHENTICATION_LEVEL=0)
)

# Configuration of client

# We need to configure the client to use CMAN. It is needed make some
changes in tnsnames.ora and sqlnet.ora

TNSNAMES.ORA

sid_db.WORLD=
(DESCRIPTION_LIST=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=xxxxx)
(PORT=1610)
)
(ADDRESS=
(PROTOCOL=TCP)
(HOST=xxxxx)
(PORT=1521)
)
)
(CONNECT_DATA=
(SID=sid_db)
(SOURCE_ROUTE=YES)
)
)
)

SQLNET.ORA

# We should say that sqlnet will use CMAN, so add this parameter to the
file:

USE_CMAN=TRUE
