Re: ICF Catalogs on SMS managed volumes

Bob you are right. CATALOG backup and recovery gets special attention
here as well with backups during our normal nightly point in time copy
window as well as special backups the next day before prime daytime
processing.

We use T-REX from Dino Software http://www.dino-software.com/

There are other good products but I don't think in a large ICF catalog
environment just IDCAMS, ICFRU, and DFHSM are good enough.

I am a little leery of letting DFHSM backup catalogs using EXPORT
automatically. We have seen performance issues in the past with EXPORT
running on large catalogs. That is one of the reasons we use T-REX for
backups it is a lot faster. You can have too many backups if the DFHSM
backup slows us down during busy processing.

Sam,

As others have pointed out, it really doesn't matter where the catalogs
are allocated.

In my opinion, what *does* matter are your DR considerations, *and more
importantly*, what catalog backup and recovery tool your shop is using.
As Ron Ferguson always taught, "Catalogs do break!" And he should know.
