The definition is

kernel.sem: max_sem_per_id max_sem_total max_ops_sem_call max_sem_ids

We use the SuSE provided suse-sapinit.rpm to change the parameters at
bootup. For quickly changing this:

- edit /etc/sysctl.conf
- add 
        
        kernel.sem=4096 512000 1600 2048
  
  without quotation marks and the like
- execute 

        # sysctl -p /etc/sysctl.conf

If you then have a look at the parameter again via 

        # sysctl -a | grep sem

you'll see that is has changed.

The RPM I talked about will just add the call to sysctl to the startup
scripts. 


Hope this helps :-)
