Is there any possibility to set the values for IPC-ressources
(SHM/SEM) other than by changing the headerfiles?

A software we want to install wants us to have set the following
values:

SHM MAX 33554432
SHM MIN 1
MNI 128
SEG 128
SEM MNI 128
SEM MNS 4096
SEM MNU 4096
SEM ONE 32
MSL 32
MAP 4096

I know from HPUX that there is something like /etc/system for this kind of
params...

Sure, that's what sysctl is for. See sysctl(8) or /proc/sys/kernel/ .
