We're running a Web Agent on Apache on Linux. Could you tell us what
Linux system parameters are related to :
MaxResourceCacheSize
MaxSessionCacheSize
Web Agent parameters ?
We want to make sure we have the right system settings on our Linux
OS's.
The ACO parameters :
MaxResourceCacheSize
MaxSessionCacheSize
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:
Kernel 2.6
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.
set shmax:
# 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).
