Re: Backing up from your Mimix HA machine

Well, I guess a question is does your HA config get EVERYTHING you want
backed up on a nightly basis? Another is do your regularly role to the HA
system and run? What would it take to rebuild the Production/Source system
and can the backups from the HA provide what is needed.
In theory, This process can minimize your downtime window for backups as
long as you are getting what you need and know how to recovery. You may
still need a Local Full Save or Save IBM. Are these machine local ( cross
town or inthe same room ) vs 1,000's ot 100's of miles apart? How often do
you grab last night's or last week's tape and restore?

Suppose your source machine is GDIHQ and your target machine is GDIHQ2. I
am hearing that we should forego backups on GDIHQ and we should be backing
up from GDIHQ2 as to not disrupt our line of business.
Do you have any documentation on the "best practices" of doing that? Like,
do I shut down Mimix enough to free the locks and allow us to perform our
backups but not so far as to kill the remote journals from still getting
their entries?
We want to use BRMS.

Yes, lots of installations do their backups on their HA systems. There
really isn't an official "Best Practice" recommendation, but personally, I
would set it up just as you describe. Specifically, you can do:
<mimix>/ENDDG DGDFN(*ALL) PRC(*DBAPY) ENDOPT(*IMMED) ENDRJLNK(*NO)

at the beginning of your backup process, then restart the MIMIX processes
with:

STRDG DGDFN(*ALL) PRC(*DBAPY)

Sounds pretty straight forward to me. Does anyone have any comments or
suggestions?
