HI all,

I'm using: Linux Suse personal edition 8.2

I am using the dbca with Oracle 9.2. It keeps
running out of memory with the ora-27123 error.

As the docs said, I did this:

echo `expr 2048 \* 1024 \* 1024` > /proc/sys/kernel/shmmax

cat /proc/sys/kernel/shmmax
2147483648

reboot

---------------

But, then I got the same symptom.
I checked the file.

cat /proc/sys/kernel/shmmax
33554432

So, it didn't keep the value!!!

ipcs -l

------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 32768
max total shared memory (kbytes) = 8388608
min seg size (bytes) = 1

------ Semaphore Limits --------
max number of arrays = 1024
max semaphores per array = 250
max semaphores system wide = 256000
max ops per semop call = 32
semaphore max value = 32767

------ Messages: Limits --------
max queues system wide = 128
max size of message (bytes) = 8192
default max size of queue (bytes) = 16384

In Solaris, this was easy. Edit the file:
/etc/system
and reboot. The values stayed there forever.

But how to do this in Suse, and make it stick?

I don't want to put this in some script, so they
get changed while booting, and add yet another
layer of complexity.

Thanks
