Ok, I had forgotten Linux could do that, so that could get all of the vdisk pages moved (assuming there are no other vdisk uses), but it does "stir the pot" in terms of recency of reference (all of those pages have to become resident and then age back out through the paging hierarchy (which isn't ideal), and it won't get other types of CP owned pages, but it might be enough for some shops. - Bill Bill Holder, Senior Software Engineer IBM z/VM Development, Memory Management, Endicott, NY Phone: 607-429-3640 IBM TieLine: 620-3640 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
