I have a Suse 9 Linux system

These are the commands I ran on my system.

getconf PAGE_SIZE

4096


free
total
Mem: 10324860

/sbin/sysctl -a|grep shm

kernel.shmall = 2097152
kernel.shmmax = 4294967295


I have a page size of 4K, I have 10GB RAM,
The Kernel has been set so that
shmall = 2097152 * 4096 = 8,589,934,592 (approx 8 GB)
shmmax = 4,294,967,295

Is it possible to increase shmmax ?
I tried to bump this up to 5294967295 or 6294967295
but system defaulted to 3 GB

Please help.
