Hm, did you mean delayed/lazy paging? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

Hi.. I just stumbled back upon this while cleaning out my inbox this morning. There's not much mention, under 1,000 possibilities come back, during a search for "deferred paging" in quotation marks. These two sources sound like they might fit the question: #1) Paging Spaces by Tom Farwell; April 2003; IBM Systems Magazine NOTE: Appears to potentially be a popup window that search engine perceived as a regular webpage http://ibmsystemsmag.com/CMSTemplates/IBMSystemsMag/Print.aspx?path=/aix/adm...) First reference is near the top under "AIX 4.3.2+ Deferred Paging Space". This is a quick quote that sounds like it might trigger an ah-ha moment for some: "[...] Deferred Page Space Allocation (DPSA) policy. DPSA delays allocating paging space slots until it's necessary to page out the frame to paging space." "DPSA delays allocating" sounds like it falls under your "delayed/lazy" reference. :) And...... #2) AIX 5L Differences Guide Version 5.3 Edition By Scott Vetter, Adrian Demeter, Shiv Dutta, Armin Röll, SeongLul Son, IBM Redbooks https://books.google.com/books?id=Vrq6AgAAQBAJ&pg=PA180&lpg=PA180&dq=%22defe... Keywords that help this sound appropriate are "AIX paging space allocation policy and management" within a section titled... "Paging space garbage collection". That provided an explanation that was fairly *cognitively friendly* for me, a user who has never touched on this concept in her own computing petri dish. Well done @ the author(s). :) Posting for the archives. Hope it helps someone someday. :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * I comment, therefore I am... procrastinating elsewhere. Indubitably. *

I feel sorry for anybody still running either of these AIX versions (4.3.2 is late 1998, 5.3 is from 2005). Word of warning - AIX is *highly* different from Linux - it's even diverged an amazing amount internally from its SYSV Unix roots. I wouldn't take any AIX internals documentation as helpful for Linux, unless you also found the Bach book on the SYSV kernel and Kirk McKusic's book on the BSD4.3 kernel useful in understanding the Linux kernel.... I've done AIX for a living from (roughly) the RT days, through AIX/370 (now *that* was a beta test that generated a wealth of bar stories :), and AIX 3 through AIX 5 on RS6K/Power based systems.. A lot of the stuff they do doesn't make any sense at all unless you know how IBM's mainframe systems do things (And yes, I spent a number of years doing OS/VS1/HASP and VM (SP, HPO, and XA variants)
