Oracle HTTP Server not starting. mmap: Invalid argument & /proc/sys/kernel/sem

I have a Debian Linux 2.2.19 installation with 384MB RAM (unsupported I know, but nearly everything seems to work correctly. i have applied all redhat patches including binutils-2.10)
I have downloaded and installed a Oracle 9iAS installation. All the services started, except for the Oracle HTTP Server. On trying to start it manually, i get:

[Fri Jul 5 14:13:29 2002] [warn] pid file
/cache/oracle/product/9iAS_9.0.2/Apache/Apache/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run?
[Fri Jul 5 14:13:29 2002] [notice] FastCGI: process manager initialized
(pid 959)
[Fri Jul 5 14:13:29 2002] [notice] FastCGI: server
"/cache/oracle/product/9iAS_9.0.2/Apache/Apache/fcgi-bin/echo" started (pid 960)
mmap: Invalid argument
httpd: Could not mmap memory
[Fri Jul 5 14:13:36 2002] [error] Parent process has died... exiting

I think this is some to do with shm, semaphones etc.

The problem is, I have tried to set the /proc/sys/kernel values as specified in the Installation Notes, but /proc/sys/kernel/sem is nowhere to be found. I have tried rebuilding the kernel, but this seems to introduce more errors!

Questions are:

• Has anybody else come up with this error on Linux, and how can it be solved.
• Secondly, how do I get the sem params to show up under /proc/sys/kernel?
