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

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.

Yes you could just start the controlling subsystem but I would make sure
you put in some control points and error handling. That's when a data
queue comes in really handy. Have the start up program put an entry
into the queue. The CL in the control group waits for the data queue
entry and off you run. Now you don't have to guess how long it takes to
run the start up program.

Doh! (slapping forehead) You're doing it with a single control group.

I

was thinking 2 separate control groups with the first restricted.

All I have to do in that CL is start the controlling subsystem, right?

Do

you put a delay in that CL to give it some time after the STRSBS is run?
I've still got my "restore system to normal state" program from years

ago

when I didn't have BRMS and that's what I did.

The control group calls the CLP program via *EXITs. Now just start

the

console monitor, submit the BRMS job to *CONSOLE and stand back.
