Shared Memory Segments Problem Oracle 8.0.5 on Suse Linux 6.0

Hi All,

            I've installed Oracle 8.0.5 on Suse (6.0) linux, and have come up against a major problem. Everything about the installation appeared to go fine, right up to the point where I tried to create a database. When I typed "startup nomount" I was presented with the following error:

            Oracle Server Manager Release 3.0.5.0.0 - Production

            (c) Copyright 1997, Oracle Corporation. All Rights Reserved.

            Oracle8 Release 8.0.5.0.0 - Production

            SVRMGR> connect internal
            Connected.
            SVRMGR> startup nomount
            ORA-27125: unable to create shared memory segment
            Linux Error: 38: Function not implemented
            SVRMGR>

The error message appears clear enough, and normally I'd make the required adjustments and try again. However, I had already altered the various kernel parameters and re-compiled. I'm using the values below:

       /usr/src/linux/include/asm/shmparam.h

#define SHMMAX 0x8000000 /* max

shared seg size (bytes)         */


                    #define SHMMNI 128


/* max num of segs system wide      */


                    #define SHMMIN 1


/* min shared seg size (bytes)          */


                    #define SHMSEG 128                                    /*


max shared segs per process      */


        /usr/src/linux/include/linux/sem.h



                    #define SEMMNI  128


/* ?  max # of semaphore identifiers              */


                    #define SEMMSL  32


/* <= 512 max num of semaphores per id     */


                    #define SEMMNS  200                                  /*


? max # of semaphores in system              */


                    #define SEMOPM  32                                    /*


~ 100 max num of ops per semop call       */


                    #define SEMVMX  32767                             /*


semaphore maximum value                         */

When I issue the "ipcs" command I get the following:

            ipcs
            kernel not configured for shared memory
            kernel not configured for semaphores
            kernel not configured for shared memory

The machine has an AMD K6-2(400) processor with 128Mb RAM, so I seriously doubt that it's anything to do with resources.

My question therefore is this, how exactly do I configure the kernel for shared memory? On other unix platforms I've used, altering these parameters, or their equivalents is enough to do the trick. Am I missing something?

Thanks in advance.
