Check system settings

Gd Day Forum,

I would need to find out how much semaphores and shared memory segment resources have been allocated on this Linux server?

Is anyone able to help me on that?

Thanks/Cliff

Maximum shared memory and semaphores allowed can be found from /proc file system.

check /proc/sys/kernel/shmmax (for shared memory)

you can directly update them, or update them using sysctl command (as root user).

Hope this helps,
Gopi

file /proc/sys/kernel/sem contains details about it.

Contents of this file along with other kernel parameters are mentioned in proc man page (check 'man 5 proc'). search for sem.

Hope this helps,
Gopi
