Mark is absolutely correct that you can't share PDSE/xFS datasets across SYSPLEX boundaries, but the reason is more complex than just the scope of the ENQ. MIM will faithfully take proxy ENQs on every system in the MII sharing complex no matter how many SYSPLEX instances are involved. If that was all there was to it then "it would work". And too many people believe they really can share outside of a SYSPLEX, despite acres of documentation to the contrary. HFS and PDSE are essentially memory-mapped files. The system components that manage the space allocation for those files communicate with each other using XCF and XCF is limited (by definition) to the SYSPLEX. Change the space map outside of the XCF scope and its good night and thanks for playing. It is entirely possible to share those resources in a read-only manner across SYSPLEX boundaries. It is equally certain that writing to a dataset (improperly) shared in that manner will result in a broken dataset and grief to the consumers on both sides. Ask me how I know....
