Oracle 7.0.15 Multi-Threaded Server w/SCO Unix Setup Prob!

I've had one hell of a problem tring to install SQL*NET V2 multi-threaded server (dispatchers). The information needed is scattered in many manuals and some arn't even accurate (several changes from 7.0.11 - 7.0.13 - 7.0.15). Also, the auto-configure routine is made to work for people who have SQL*Forms (I don't). Anyway, in a nut shell, I have been pulling out my hair over this. Thus, I'm posting here. :)

I have SCO UNIX 3.2 v4.2 with TCP/IP RUNTIME (most recent version with lli drivers). I also have Oracle 7.0.15 installed/running (works fin without MTS). I'm just tring to get MTS to work on a single machine to save memory from all the oracleorac instances that exist for every user/program (100k+ for each program just waisted). I don't need to use any other services of SQL*NET other then the dispatchers of MTS!

After getting as far as I could, I am getting the following errors when tring to start the database with MTS parameters in the INITORAC.ORA file.

00101, 00000, "invalid specification for system parameter mts_dispatchers" // *Cause: The syntax for the "mts_dispatchers" parameter is incorrect. // *Action: refer to the manual for correct syntax. 00102, 00000, "network protocol %s cannot be used by dispatchers"

// *Cause: The network specified in "mts_dispatchers" doesn't have the
//         functionalities required by the dispatchers.
// *Action: refer to the manual on network protocols supported by the
//          dispatchers.

The %s in the second error contians the string "ipc" when it dumps to the screen. Problem is, the only thing I did to the initorac.ora was to uncomment the defualt MTS stuff:

mts_dispatchers = "ipc,1"
mts_max_dispatchers=10
mts_servers=1
mts_max_servers=10
mts_service=orac
mts_listener_address = "(ADDRESS=(PROTOCOL=ipc)(KEY=orac))"

So why isn't "ipc" valid here? I've tried things like "soc" and "uds" and a few other older things, but nothing helped. One would assume the remarked fields in the shipped init.ora file would have worked- what am I missing?

Also, I can't start the listener and that is probably because the MTS stuff never started, but here is the info on that as well:

# FILENAME: $ORAHOME/network/admin/listener.ora #
LISTENER=

     (ADDRESS= 


        (PROTOCOL=ipc)


        (KEY=orac)


     )

     (SID_DESC=


        (SID_NAME=orac)


        (ORACLE_HOME=/u2/oracle)


     )

# FILENAME: $ORAHOME/network/admin/tnsnames.ora #
orac=
  (DESCRIPTION=

     (ADDRESS= 


        (PROTOCOL=ipc)


        (OBJECT=LISTNER)


     )
     (CONNECT_DATA= 


        (SID=orac)


     )

And the output I get from issuing:   lsnrctl start

If anyone has any ideas, hints, manual pages, etc... I need it all :) I'm
baffled by this.
