Re: Logical files not in same library as physical files

Disaster recovery DISASTER.

Aside from being confusing, opening the door to getting the index/view on
the wrong table due to library list issues, and generally being a real
pain, it sets a bunch of landmines for any kind of recovery.
IBM has done quite a bit of work in SAVE/RESTORE to try and mitigate the
dangers, but they still lurk.

90% of the test recoveries we do, and almost 100% of the actual recoveries
are not complete due to cross attached logical files, requiring extended
downtime to re-restore or rebuild them. Keeping in mind a logical is
different from a stand alone index or view, it is a hybrid object that
contains both.

All,

I know that we can create logical files in different libraries than
the physical files, but I don't like that idea. What are your thoughts as
to the advantages/drawbacks of the multi library approach?

All the best,
