Perfkit -- User paging menu can show you who is doing the majority of the paging, who is most active, who owns the most in xstore/dasd.
As far as tracking the pages with 'old' data, etc -- I'm not sure of a way to do this. I believe you can end up with a lot of pages that don't go away when using VDISK, for example, so it could be interesting to track it. Scott On Tue, Feb 10, 2009 at 7:04 AM, Martin, Terry R.
