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?

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?

Thanks

Dear ossentoo,

If you built your own kernel you probably need to rebuild enabling
System V IPC semaphores: under the "general setup" kernel config menu
(at least, that's
where it is in 2.4).

Please, let me know if this is the fix and I can repost as an answer.

Thanks.

HI,

I already had System V IPC enabled (CONFIG_SYSVIPC).  That's the
correct option right?
