RE: At the risk of sounding like an AS/400 rah-rah...

The original point was:

"AND we can't run production batch jobs until
our client service center goes down for the day, because of the
negative impact the batch jobs have on the service center screens."

I don't know exactly what this guy is talking about -- it could be processor
contention, DBMS contention, or record locks.  I think a well written
application can deal with record locks to allow batch updates and online
processing to coexist reasonably.  I think that a well configured database
installation can address the database contention issues.  I think that on
any system you can isolate batch processing requirements from online
processing demands.  Both DBMS and processor contention issues can often be
traced back to either poor sizing of hardware or poor configuration.

All of these issues can be dealt with through system administration,
database administration, and/or application design on any platform.  Which
platform makes it easiest by far is another matter entirely...

And this ability (to schedule jobs to be run unattended when nobody is on
the machine) is not unique to the AS/400.
