When Good Work Doesn't Go To zIIP / zAAP Heaven
Whenever I talk about zIIPs and zAAPs I'm reminded of Zip Zap miniature radio-controlled cars . But (to get past the censors I have to say) zIIPs and zAAPs are not toys. Here's an extract from a post on MXG-L that Bernie Pierce made. (I reproduce it with his kind permission.) If there is contention for the local lock, the cross memory local lock, the CMS lock or any other suspend lock, units of... [More]

DB2 Data Sharing Performance and Coupling Facility Enhancements for DB2 Version 8
Occasioned by some recent enhancements to MXG I thought it high time I talked about a couple of Coupling Facility commands that DB2 Version 8 can take advantage of: (And thanks to Barry Merrill for the MXG information and the sample data I'm using here.) MXG Version 25.04, May 7, 2007 provides support for these enhancements. Coupling Facility Level (CFLEVEL) 13 introduced the WARM and RFCOM... [More]

Serious Work of Drinking in München
Thanks to Margaret Koppes of the European Patent Office for this picture of me and Glenn Anderson hard at work at the "main tent session" :-) in München:

UKCMG Conference, June 25-27, Whittlebury Hall, Northants
I've just submitted my three presentations for this great conference: Much Ado About CPU Memory Matters in 2007 DB2 Data Sharing Performance For Beginners UKCMG is - for me - a great chance to catch up with customers, vendors and others in the industry. Its prime focus is Performance - multiplatform in fact - but we always have a thumpingly good showing of mainframe and DB2 topics. And this year... [More]

Gameframes
Hmmm: IBM press release on the gameframe . I'd like to see a lot more detail on this before I go "whoopie!" but it does sound like an intriguing idea. It would be the first "specialty" engine to actually feature different hardware. Reminds of me of the 3090 Vector Facility but it's really nothing like it. And at this stage there's nothing about what will actually be shipped. Still, I'm happy to... [More]

What I Learned From My Conference Evaluations
I was pleasantly surprised to see my conference evaluations so soon - given the European System z Technical Conference was only last week. Very professional to have the feedback straight away. All the people who filled in the evaluation forms - and that exceeded 50% of the attendees in every session - were very kind, I feel. Here's what I learned: I still talk too fast, and still have highly... [More]

European System z Technical Conference - End of Day 4
Parwez Hamid: System z9 BC GA2 and System z9 EC GA3 Update Available from 11 May, Driver Level 67 provides the BC GA2 / EC GA3 enhancements. The current one is 63. Parwez set the expectation the upgrade can be done non-disruptively if you plan carefully. Common to BC and EC machines: LPAR Group Capacity Limit. Group of LPARs on one footprint need not be in the same parallel sysplex. Requires z/OS... [More]

System z Tech Conference - End of Day 1
It's been really nice meeting with so many acquaintances. The highlight of Day 1 was undoubtedly Pat Artis presenting on HyperPAVs. As I have a couple of foils on HyperPAVs from the DB2 perspective on Thursday it's going to be nice not to have to explain them in too much detail - as Pat did such a great job.(The Thursday session is on I/O and DB2 Versions 8 and 9, a much wider ranging version of...

European System z Technical Conference Begins
The agenda this time is chock full of great sessions. I've "marked my card" for every single session . Bob Hoey - marketing guy though he is - is giving a keynote speech that fills one with a lot of hope for the mainframe. (Bob, if you know nothing else about him, participated in the infamous "IBM Mainframe Marketing" videos that appeared on You-Tube a few months ago.) So I'm really looking... [More]

IBM System z Technical Conference 2007
This year's IBM System z Technical Conference is 16-20 April in Munich. Now I've got my three presentations together I can relax and have just perused the agenda: There are some very good sessions and some excellent speakers. My sessions are: Much Ado About CPU I've worked pretty hard to move the z9 stuff into the main flow and also added stuff on z/OS R.8 and a tiny bit on R.9. I think it's... [More]

An Excellent Paper on Uniprocessor Performance Management
My good friend Linda August (of the IBM Washington Systems Center and previously of the global Performance Management team I was a member of) has written a very good paper (and an accompanying presentation she gave at SHARE in February). The theme is highly topical: The management of uniprocessor LPARs. Topical because of the increased uniprocessor speed of the z990 and particularly the z9... [More]

Not Just People Twittering - Vehicles As Well
Here's an interesting BBC News Article: Vehicle warning system trialled . So let me see now, when we said the fridge would talk to the microwave - as everything would have an IP address - did we really envisage that they would Twitter? :-) Can you imagine "The Bloggings of an uncleaned fridge?" :-) And can you imagine what'd happen if my fridge started Twittering and next door's microwave yakked...

Twittering and Blogging
Here's a useful contribution to the debate about Twitter: From a friend's blog . There's much mileage in the comments - which is where the action really hots up. :-) Actually her blog is in general a good read - but maybe I'm biased as she's a friend of mine. She's a Web 2.0 enthusiast with a great line in photos and original art. (If you want a business justification for reading her blog she's a... [More]
