This document explains why you may not be able to see your collection data, even though the Xmanager says that it's active.
Client disabled his Cross system communication. Now, he's unable to see his collection on one of his 2 local Xmanagers. Why?
z/OS 1.11 and above.
The XMANID in Client's Development CDBAPARM SETUP00 member was using Production XMANID, instead of the Development XMANID. He corrected this & recycled his Xmanager.
