DB2 Version 9 – STATIME Default Decreased to 5

(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”

DB2 Version 9 RLF – Not Just For SAP

(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”

I May Not Know Who You Are But I Have Some Idea Why You’re Here

(Originally posted 2007-10-08.) I don’t think you can see this information but I can see what are called “Referrer URLs” for hits on this blog. (The HTTP protocol defines a header that contains the URL you came from – when you clicked on a link.) Disregarding the several “Direct” hits – which tell me nothingContinue reading “I May Not Know Who You Are But I Have Some Idea Why You’re Here”

Bye Bye Internet Explorer

(Originally posted 2007-10-07.) Finally the last web application I use that required Internet Explorer is replaced with a Firefox-friendly version (or so we’ve been told). Hurrah! Except, as always, I’ll believe that when I see it. (This is our Online Travel Reservations application that used an ActiveX control. Now it looks very much like anContinue reading “Bye Bye Internet Explorer”

Is UCB Too Obscure For Wikipedia?

(Originally posted 2007-10-04.) Well, is it? Apparently there are umpteen (count’em if you want a more precise number) 🙂 expansions of the acronym “UCB”. But the one I care most about is Unit Control Block. (I think had been born before this meaning came into being – but I’m not sure.) 🙂 Actually Unit ControlContinue reading “Is UCB Too Obscure For Wikipedia?”

Memory Metrics Now That z/OS Release 8 Is Upon Us

(Originally posted 2007-09-27.) I was asked an interesting question today by a customer – one with dozens of LPARs and therefore not much time to study each one in excruciating detail… “Given that System High UIC (hereafter referred to as ‘UIC’) behaves differently in z/OS R.8 how should I treat it?” I’ve posted on thisContinue reading “Memory Metrics Now That z/OS Release 8 Is Upon Us”

System z Technical Conference, San Antonio TX

(Originally posted 2007-09-26.) Last week I was at the System z Tech Conference (again getting my zeds mixed up with my zees). 🙂 I presented 4 times, one of which was a repeat. What’s especially nice is that I got 87 attendees for the “Memory Matters in 2008” presentation – spread across 2 sessions. ThisContinue reading “System z Technical Conference, San Antonio TX”
