Tuning - Kernel parameters

[Alexander Maldonado]

I have some processes of oracle 8i on HPUX11.11, in wait state due to insufficiency of semaphores, the configuration of the parameters of kernel is:
sema 1
semaem 16384
semmap 4098
semmni 4096
semmns 4096
semmnu 2048
semmsl 4096
semume 1024
semvmx 64000

I accep suggestions about this, the minimum values recommended by Oracle are set.

Hi Alexander
Heres what I have on one box:
semmni 4096
semmns (SEMMNI*2)
semmnu (NPROC-4)
shmmax 0X80000000
shmmni 512
shmseg 400
sysv_hash_locks 200
On another:
semmni 4306
semmns 8612
semmnu 4112
semume 30
shmmax 1073741824
shmmni 512
shmseg 200
...
But looking with sysdef
both have:
e.g.
sema 0 - 0-1 -
semmap 4305 - 4- -

sema set to 0 which is not your case...
If you change the value, it will be taken account on next reboot only...


All the best
Victor
