I'm not familiar with SuSe but I think there should be an
rc.local file that is run during the system boot.

If you want to set it to "2147483648" then do it like this.

Edit /etc/rc.d/rc.local and add the line below to the end of it.

/sbin/sysctl -p

Edit /etc/sysctl.conf and add the line below.

kernel.shmmax = 2147483648

Then run "/sbin/sysctl -p" to update /proc without rebooting.
That should cause it run and update /proc during system boot.
