We're running a Web Agent on Apache on Linux. Could you tell us what
Linux system parameters are related to :
Web Agent parameters ?
We want to make sure we have the right system settings on our Linux
The ACO parameters :
are related to semaphores and Shared Memory.
On Linux the recommended minimum values for semaphore/shared memory
settings for kernel 2.6 (as well as 2.4 if and where it differs) are:
Use "sysctl kernel.sem" to see actual value of SEMMSL, SEMMNS,
SEMOPM, SEMMNI respectively.
Reuse SEMOPM and SEMMSL and modify SEMMNI and SEMMNS as (to modify
SEMMSL, SEMMNS, SEMOPM, SEMMNI respectively.)
# sysctl -w kernel.sem="250 32000 32 128"
SEMMNU is set internally as SEMMNI.
# sysctl -w kernel.shmmax = 2147483648
shmseg is internally set to shmmni and you can set this with:
# sysctl -w kernel.shmmni=24
(this is set to 4096 on sles9).
