Re: How can I copy only certain file types to tape and/or

I came in the middle of this discussion, so I am sorry if I repeating 
something already stated, that you might need to review.

If you do a SAVE 21 RESTORE 21 IBM supposedly gets everything you need, but 
if you do selective restore, you can have a problem if LF in different 
library from PF it is for.

We are on BPCS in which each environment (data base) has PF with SAME NAME 
as in each other, along with a pile of LF to point at the PF in that data 
base.  LF out of the box from the vendor are in same library as PF, LF that 
we add are in a library with a different name.

Now when you do a restore of several libraries, they get restored in 
alphabetical name sequence of the libraries.  Let's suppose library with PF 
is restored first, all well and good, but suppose library with LF is named 
alphabetically before library with PF they pointed at, basically you lose 
the LF, and have to know this, so you can restore those LF after you got 
the PF restored.

Not supposed to happen, but sometimes when we copy files from one 
environment to another, can end up with LF of one environment pointing at 
PF in another environment.  Use DSPDBR to check what's pointing where, and 
know naming conventions to see if any messed up.

Assuming you have the source code for the LF, you can always delete the LF 
and recompile, since the data is in the PF, but then you have to make sure 
you got all the right members are in which LF.  There is a ceiling on how 
many members can be in an LF like 32, and some of our PF have in excess of 
200 members.
