Performance Numbers and the Redbook
So, I'm about to start writing. At last! As a team we had a discussion yesterday about how to deal with performance numbers. One of the roles I'm playing on the team is "the guy who writes about performance numbers". So we came to the following conclusions: We really can't talk about products made by other people - such as SAS/MXG or TMON for DB2. That's right out - because of our basic provenance... [More]

Is It The Structure Or The Content That's Important?
The other three residents are busy doing extensive setup work - and we hope to have some nice measurements later on. (I'm not sure how much later on there actually is, mind.) :-) So I have no RMF or DB2 SMF to play with yet. :-( Meanwhile I'm beginning to come up to speed again after the glorious experience of recovering from moving five time zones to the west. :-) So I actually got to writing...

A Minor Fact About Lock Structures
Sometimes reading the SMF manual buys you less than you thought. I had completely ignored a nice little field - and the code I inherited to analyse SMF 74 Subtype 4 Coupling Facility data ignored it as well. R744SLEC in the Request Data Section for a structure is described by the text "Lock structure only: lock table entry characteristic". Can you guess what it is? :-) If I told you it was a one...

Cache Structure Information
It's fair to say I've written very little in terms of book words these past two days. That's because I've been "doing research" on how the cache structure counters really work. "Doing research" is a euphemism for "finding out how the heck the darned thing works". Which is in itself a positive thing to do - but it does rather get in the way of writing stuff. :-( There is a section in the SMF 74... [More]

Back From Vacation And Raring To Go - To Poughkeepsie
Usually when I go away on holiday I bring something back with me. Often in the form of fresh ideas. This year it's been such a hectic one that all I did was to flake out. So no new ideas this time. Perhaps that's a good thing, perhaps not. But I think I did achieve something: Mental decluttering. So I can, for example, look at stuff I was working on with a fresh take. And the timing is...

Touring The Upcoming Batch Optimization On z/OS Redbook
As mentioned here , I recently participated in a residency in Poughkeepsie. Our task was to write the "Batch Optimization on z/OS" redbook that we hope will get out soon (though I think early next year is the most realistic timescale). These past two weeks I "toured" the redbook in the Nordics: 5 cities in 2 weeks (Helsinki, Copenhagen, Oslo, Stockholm and Aarhus). I really... [More]

New Batch Residency
In October Frank Kyne and I expect to run a residency in Poughkeepsie.
You can find the announcement here . The residency builds on the ideas presented here and three subsequent posts. I revisited a specific part of it in
Cloning Fan-In . So what are we going to do? For a start we're going to assemble a team of 4 skilled mainframe folks from wherever we can. One of them will be me, which leaves... [More]
