I recently converted several PSF libraries, resulting in a problem if a dasd reorg moved the dataset while PSF tasks are up. PSF does not issue an enqueue but has the dataset open. The volume reorg only checks for enqueue before moving the dataset. Short term, we configed the reorg to skip PSF datasets. Long term, looking at setting DSI and setting a dataset close flag in a PSF exit. Or just taking down printers before reorg in the wee morning hours.

We are currently thinking about converting many of our PDS libraries to PDSE. While researching the possible pitfalls to a PDSE one that concerned me the most is "Blocked Workload" that Thomas Reed discussed at SHARE in 2018. This situation is said to occur when CPU is near 100% (pretty common event from time to time here) so it certainly caught my attention. Does anyone have any experience with Blocked Workload? Anything else I should be looking closer at?
