Re: BRMS - full save with least amount of restricted time

1) Not that I have seen
2) TCP must be starting on it's own as the result of the IPL attributes. That's OK, it won't affect the save.
3) BRMS Exit program waits to see the data queue entry. Start up program enqueues the entry. I would clear the data queue in any case at the end of the control group. Maybe a bit later by another job so you can inspect the contents of the queue if you want, but clearly it has to be clear when the process starts

Jim,

A couple more questions here, then I hope I'm good to go.

1) The STRBKUBRM will be run with SBMJOB(*CONSOLE). Normally, BRMS would
restart the controlling subsystem at the end. BRMS won't fall over at the
end because I've done it in the middle, will it? For all I know, the BRMS
console may already be checking to see if the controlling subsystem is up
before trying to start it.

2) My QSTRUP program only takes 40-45 seconds. However, QSYSOPR shows
various things happening after that. For example, the message "STRTCP
completed successfully" doesn't show up for another 5 minutes. Are you
truly moving on in the control group after QSTRUP is done (ie, 40-45
seconds)?

3) If I use a data queue to determine that QSTRUP has ended, it seems to me
that I want to clear this data queue in my BRMS *EXIT program, not in
QSTRUP itself.


I will probably be testing this stuff a week from Saturday and just want to
keep the Saturday time as brief as possible.

Thanks again for your help. These forums are a godsend.
