RE: is operating system always to blame, was: Ready to scrap an AS/400

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

I believe that it is still possible to fill the disk on an AS/400 if you
leave database monitor running for many hours.  This catastrophe can happen
on an AS/400 - the machine that prevents SNADS transfers when they exceed
the disk threshold.  You may presume that I am speaking from experience.

I was VERY cross with my friends in the IBM Rochester database group for
allowing this to happen.  If I do it to myself, I have no excuse.  In my
opinion, Rochester should never create a generally-available tool that can
kill a system.

By the way, I have learned several ways to prevent this from happening.
That particular zealous pursuit of knowledge probably wouldn't have happened
without experience.

The OS should protect itself from malice and stupidity.
