The OP wrote that he had two monoplex systems; that's n ot an option
unless he puts them in a single sysplex.

Both systems opening the same dataset.

Absolutely wrong. You're assuming that every relevant ENQ is a
RESERVE; some are not. It is not possible to convert an ENQ to a
RESERVE, because there is no way to determine the proper UCB address.
Converting SYSTEM to SYSTEMS in a monoplex doesn't change anything.
>BTW: such exposures can exist when GRS is used, but misconfigured.
Il va sans dire!
