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



fixed

Thanks, Jim.

How do you do that with a CL program, when restricted state gets involved?

What I mean is this. We have the Advanced Job Scheduler, which is used to
do the restricted state backups. The AJS job command is:

STRBKUBRM CTLGRP(FULLWTHSYS) SBMJOB(*CONSOLE)

Are you saying you replaced that with CALL MYCLPGM and it did it all? As
in that CL program has 2 STRBKUBRM commands in it? That can't be, I don't
think, because restricted state will kill your CL program. And you're much
smarter than that so I'm obviously not understanding something. :)

Jeff,

The main concern with save while active on an *ALLUSR is when you use
any synch point except *LIB. *SYNCLIB and *SYSDFN may take a LONG time
to reach a synchronization point with all of the libraries on the system.

If you use *LIB as the save while active synchronization point you
should not have any issues, I do it all the time.

I also use the technique you mention with two control groups, one for
restricted state for what ever is needed there, then bring the system
back up for use and start a save while active on the other libraries.

I use a control language program to do it so I can manage the shut down
and start up properly.

I read in "Backup Recovery and Media Services
for OS/400: A Practical Approach" (PDF available here:
http://www.redbooks.ibm.com/abstracts/sg244840.html) that save while
active
is strongly discouraged with *ALLUSR. The last update to this redbook
was
2003, so I'm wondering if that's changed. Anyone doing *ALLUSR save
while
active?

Another thought I had was to put the *SAVSYS in one control group
(restricted state), everything else in another control group (not
restricted), and run them back to back. This might be trickier, though,
as
the first control group has to finish before the next one starts. I
don't
know if BRMS has that built in or not. Just thought of that idea while
writing. Also, since I want everything on a single tape, I need to make
sure the 2nd control group doesn't clear the tape.

Suggestions welcome.
