Re: BRMS sometimes saves entire IFS

Thanks, Jack!  I'm getting my information from DSPLOGBRM.  Well, also from DSPLOG QHST because it's easier to compare that specific message day over day.  I'm pretty sure it's the same control group; a scheduled job runs the same BRMS command every day.  I just don't get it.  I'll look at PRTRPTBRM when I get a chance and see if it tells me anything additional.

Joe, maybe you could track it down using the dsplogbrm command or try the
prtrptbrm. Maybe your running some other jobs that are using different
types of control groups.

and even got a cup of coffee and tried again, but I couldn't find any
explanation in there either.

That seems to talk about when it decides to do a full or incremental,

but I must be dense today. It doesn't seem to me like it explains how it
decides.

Yes, we're researching reducing SAVSECDTA time. That will involve

switching to authorization lists (which we should be doing anyway), but

that project hasn't been scheduled yet. This IFS issue is a different

issue that has been happening infrequently for some time now. And

looking at the logs, I don't understand it at all.


We've got this in our backup:


Auxiliary Weekly Incremental Full Retain

Save List Storage Activity Media Media Object

Item Type Pool Device MTWTFSS Policy Policy Detail

*LINK *ALLAVL IIIIIFI DAILY DAILY *YES


But from what I can tell, the system did a complete IFS save on 3/23,

3/27, 3/30, 4/06, 4/10, 4/13 and today, 4/17. I only base that on the

number of IFS objects saved (2 million vs a few thousand). I cannot

tell from the logs which type BRMS attempted. Weirdly, it doesn't seem

to me that it is EVER doing a complete IFS backup on Saturdays (3/21,

3/28, 4/4, 4/11).


4/13 was unusual in that it was an ad-hoc mid-month save during the

day. The rest all occured during our overnight processing, in which the

IFS *LINK portion usually kicks off around 2AM (unless SAVSECDTA goes

long).
