I have worked in several PRMS shops where essentially 24-hour access is
required. In each place we negotiated a time for backups -- 2nd shift
lunch or 3rd shift lunch made sense.

Then we wrote a program which varied off QINTER, submitted the backup
using Save-while-active, checked for the "checkpoint", and restarted
QINTER when the checkpoint was found. If system activity is low, the
checkpoint processing can be remarkably fast; an hour of downtime for
the backup. If you need MRP nightly, that may take more time.

We also negotiated a weekly window for full system save (typically
Sunday night) and automated it as well, and included a full system save
in the monthend processing. And finally, we put a standalone STRSBS
QINTER in the scheduler for 6am or so just in case there was a problem.

The first time I set this up I was not prepared, and it took a lot of
negotiating. The second time I was prepared, and it went very smoothly.
You will want to have the programs done now; once the decision is made
they will start quickly. If you are prepared and tell them how it will
work you are more likely to get what you require without as much
resistance. Do not budge on the need for DAILY backups; you may be able
to wiggle on nightly MRP, or run it at a different window.

Good luck.

Do have any window in which BPCS can be down?

we are contemplating adding a graveyard shift. this would mean that we
would need to have BPCS available on a 24 hour basis for inquires,
inventory, and labor posting. we need to run MRP and several other batch
jobs that access the BPCS files each night. plus we need to do the
daily data base backups on the as/400.

who has experience with this type of an environment? can you share any
thought, what to do's, or what not to do's?
sincerely
