considerations for a new(ish) systems programme:
Tom:
I would change it slightly to "How Many TSO users are signed on at one time"
An additional change (I think) - For the proposal of counting "How
Many?", consider a batch job accessing datasets belonging to a TSO
user as being "Signed On".
Also, I think that there may be an timing issue based on how many
users are signed on when catalog updating is occurring. I do not
think that just reading the catalog would be a problem but
adding/deleting datasets as well as doing the updates involved with
opening/closing existing datasets may have an effect due to locking
of the catalog during these operations.

It depends upon how many TSO users you have. IIRC, there is
a limit to the number of associations a user catalog can have.
