If you must share the volume, ensure the other data is rarely, if ever, accessed. CP starts a never-ending channel program on the paging volume to handle paging. If something else needs to be read or written, then the channel program is stopped, the other I/O is performed, and then the channel program is re-started. If you're doing a lot of paging, that's going to hurt. Alan Altmark z/VM Development IBM Endicott
