The Initiator does the ENQ.

We are currently operating a Grid configuration with four clusters.
Unfortunately some of the tapes that were inserted into our local cluster went
into the wrong catagory code. Also unfortunately we cannot get the entry exit

If I were in the position to decide which option to use,

NOPFD does unnecessary fix-ups in certains cases, which causes

MVS Solutions' Thruput Manager product is able to dynamically add limiting

Very good question.
Related... Has it been detailed just exactly what the differences between
NUMPROC(MIG) and NUMPROC(NOPFD) are? And an even better question, what (if
any) differences are there in the end results?

I think it is worth pointing out the most likely cleaning up logic used for
enqueues (note that I do not have access to GRS source - but this is how I am
guessing things work).
GRS will establish a TYPE=ADDRSPC and a TYPE=TASK resource manager routine to
cover all address spaces and all tasks i

Sorry, John. My question was unclear. It was referring to your earlier
remarks above:
Thinking about it a bit more, given what Mr. Relson
said about RTM, doing this _should_ work even if the initiator

abnormally since RTM should clean up the ENQs during EOM processing.
