I am considering sharing some usercats outside of a sysplex. What I can
find is that sysiggv2 must be kept as a reserve to do so.
Looking for others that have had to do this.
One question I had was, what happens on a ispf 3.4 when the data set is
part of the catalog but exists in another system? Ief238d?

1. You can share catalogs between sysplexes. Note: we mean BCS, which is
usually called catalog.
2. The less activity on the BCS the better.
3. The above means:
3.1. Avoid keeping non-shared datasets in the BCS. Use another BCS for that.
3.2. It is not bad idea to have multiple "small" shared BCSes.
4. You cannot use any sophisticated catalog sharing features like RLS or
ECS.
Regarding you last question: I understand it as you have entry in the
BCS, but the dataset reside on volume which is not share, that mean it
is unavailable for one system. It's nothing exotic. It's like orphan
catalog entry, which sometimes may happen even without BCS sharing
(usually as result of human error).
However that also means the sharing is not done correctly. The best
scenario is when all datasets cataloged in shared BCS reside on volumes
which are also shared. Preferably the BCS is also on the volume from
that group.
Keep it simple.
