And that's one of the landmines I was referring to in an earlier post.
Recovery Disaster....

My perennial favorite though is the developer that wanted access to
production data without copying it, so they create a logical in the
development library attached to the production file. Achieves the primary
goal. Then about 2 weeks later they create a program to manipulate that
data in some way thinking they were using test data, compiling into the
developer library, except the compiler picks up the logical pointed at
production. The developer tests the program which by mistake
deletes/updates lots and lots of records, in production. BAM landmine
going off.

Moral of the story is just don't do it......

I agree with Paul, but my all-time favorite, Richard, is the notorious
Join Logical that's in Library A using once file from Library B and one
file from Library C. Not enough head scratching in the world to understand
why on that one.

Subject: Re: Logical files not in same library as physical files

Cross-library logicals are right up there with multi-member physical
files. You can, but you'd better have a VERY good idea!

Biggest issue is saving and restoring-- the connection from the LF to the
PF is like a rubber band-- you can stretch things all over the place when
you move the LF around, but it still connects back to the original PF.

Best idea I've come up with is moving the LF back to the PF's lib, do your
save/restore, then move the LF back where you want it.

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,

Richard Reeve
