Thanks but, forget about it. I found the answer which is:
To set semaphore values in RHL (appears to be all versions of RHL, not just 9 although not 100% sure on that) you change /etc/sysctl.conf just like you do for shared memory values. The format is:
kernel.sem = <SEMMSL> <SEMMNS> <SEMOPM> <SEMMNI>
You can then either reboot OR execute "/sbin/sysctl -p". Executing "/sbin/sysctl -a" will list all parameters that can be set in /etc/sysctl.conf and the current values set for those paramaters.
