Ok, I have discovered the secret.
You may have noticed my other post on this subject. But,

You only edit a few files, and reboot. Just like in Solaris.
You need to configure -FOUR- things. NO less.
/etc/init.d/boot.sysctl is a script.
/etc/init.d/boot.d is a directory.
/etc/sysctl.conf is a parameter file.
and then you have to create a link. I used:
Edit the file /etc/sysctl.conf, and insert the value
for shmmax ...
