(Originally posted 2007-11-09.) I was contacted by the team updating the SG24-7083 “DB2 Stored Procedures: Through The Call And Beyond” this past week. Their question was quite straightforward: “One of the statements in the book, in the chapter on WLM address space management states: To help analyze the use of resources by different types ofContinue reading “WLM-Managed DB2 Stored Procedure Address Spaces”

(Originally posted 2007-11-05.) Last week I attended GSE Conference for the first time in a long while. And I’m very glad I did. Let’s get the egotistical bit out of the way first… I very much enjoyed presenting Memory Matters in 2008. If you’ve seen me present it before you might notice some minor tweakings.Continue reading “GSE Conference 2007”

(Originally posted 2007-10-27.) I’m going to have to stop adding “(sic)” after every use of the word “Referer”. As in “Referer URL”. The term itself comes from one of the standard HTTP headers. And therefore is somewhat fixed. Despite giving my “wetware spell checker” a pink fit on a frequent basis. 🙂 Anyhow, in thisContinue reading “Hackday4 and Referer URLs”

(Originally posted 2007-10-17.) Following on from Coupling Facility Async / Sync Thresholds – They Are A’Changin’ I’ve been informed by Development there is a new improved write up on how the Dynamic Sync/Async conversion works in Chapter 6 of the z/OS Release 9: Setting Up A Sysplex manual. I’ve read it and it is VERYContinue reading “More on Coupling Facility Async / Sync Thresholds”

(Originally posted 2007-10-13.) APAR OA21635 is one of a rare breed: A change to the thresholds for z/OS’s automatic CF Request conversion. (I’m told this has only happened once before.) If you recall z/OS Release 2 (in 2001) introduced a very nice function that automatically converts Coupling Facility requests from Sync to Async, based onContinue reading “Coupling Facility Async / Sync Thresholds – They Are A’Changin’”

(Originally posted 2007-10-12.) Back in April this blog entry incorporated a picture of the z9 HMC display that includes the “gas gauge” (or “power meter” if you prefer). This press release details a rather more serious purpose for the thing. And thanks to John McKown for pointing out the press release in IBM-MAIN Listserver.

(Originally posted 2007-10-11.) As many of you know I’ve been very fond of BatchPipes/MVS (aka “Pipes”) down the years (17 to be precise). So I’m pleased to seeAPAR PK34251: ADDING BATCHPIPES SUBSYS SUPPORT TO TEMPLATE UTILITY describes some new support in the DB2 Load Utility (as driven by the Template utility) which makes it muchContinue reading “New Support for BatchPipes/MVS”

(Originally posted 2007-10-10.) I’m in a session where we’re going through DB2 Version 9 migration considerations – and right now there’s a table on display with changes to DSNZPARM defaults. One of real value is that STATIME has changed to 5 minutes from 30. Unless you’ve overridden it you should now get much better informationContinue reading “DB2 Version 9 – STATIME Default Decreased to 5”

(Originally posted 2007-10-10.) Namik Hrle, the IBM Distinguished Engineer for DB2 for SAP, presented yesterday to an internal audience. (It’s the first time I’d seen him present and he’s a very dynamic presenter.) His presentation prompted me to download the Enhancing SAP by Using DB2 9 for z/OS Red Book. One item I’d like toContinue reading “DB2 Version 9 RLF – Not Just For SAP”
