Appening 3 - Editorial on iOS
Over a year ago I wrote about a couple of iOS applications I was enjoying using. [1] And now it’s time to write about a third, as it’s part of my authoring toolkit.
In
Recent Conference Presentations I showed off my then new writing rig: Byword (with MultiMarkDown) and my iPad Mini with a Logitech light keyboard cover.
I said that would be my rig for a while. So this post also... [More]

Setting MEMLIMIT
h3, h4, p {
margin-top: 2em;
margin-bottom: 2em;
} I’ve been meaning to write about MEMLIMIT and its importance for some time. [1] But it’s a moving target. So either there’s no good time to talk about it or lots of good times. So let me discuss it now and then again later as necessary. [2] So timing a post on MEMLIMIT is like choosing a wave to catch: In this case the... [More]

zIIP And DB2 Version 10 DBM1
This post adds some additional DB2 Version 10 specifics to what I mentioned in
New zIIP Capacity Planning Presentation .
I said this would be a living presentation, and so it has proven to be.
It’s had two outings so far and there are a couple more confirmed. First the times I’ve given it: On 9 April 2014 I was very pleased this was the very first presentation given at the... [More]

zBC12 As A Standalone Coupling Facility?
There’s been some interest recently in whether a zBC12 as a standalone Coupling Facility would be a good idea. Having replied to one such question in email form I can count that as a draft for a blog post on the subject. It’s a complex question as are most about Parallel Sysplex configuration design. So this won’t be a comprehensive answer but I hope it’ll give you food for... [More]

After A Decent Interval
I’m writing about intervals again. [1] Two things have occasioned this: I’ve been updating my code for DB2 Versions 10 and 11 [2] . I’ve dealt recently with customers with unhelpful SMF or RMF intervals. As I’ve said before it’s important to understand the provenance of the data you’re using.
This would be true whether it’s performance data, financial... [More]

Machines (Back To Humans)
As you know I mainly deal in SMF data (and other machine-generated instrumentation).
While I’m perfectly adept at conducting interviews and handling evidence from real live people there’s much merit in instrumentation. I’m also not keen on just replaying what you say back at you, with no value added in the process.
But I’m making an exception: I’ve just added to my... [More]

And Some More Things On The Way To DB2 Version 11
It’s only fair to warn you this gets technical straight away.
And is probably only interesting to a DB2 audience anyway.
And as someone who disclaims on his DB2 knowledge anyway you might not want to read this. Still with me?
Excellent! As described in Coping With DB2 Version 10 And Preparing For DB2 Version 11 I’ve been revamping my DB2 analysis code. [1] Here are a couple of areas... [More]

Coping With DB2 Version 10 And Preparing For DB2 Version 11
I’ve said this many times:
I’m not a DB2 person but I’ve bluffed my way in DB2 for many a year. [1] Perhaps that’s why I don’t get to use my DB2 analysis code nearly as much as I’d like. So it’s perhaps not so surprising my code fell behind when it came to new versions.
The last big update was for Version 8.
That was a big update - mainly because... [More]

What We Share And What We Have In Common
The subtext of this post is “do try and keep up” - which is directed at me as much as anybody. And is a perpetual state of being when you’re dealing with evolving SMF data and enterprise computing environments. When I look at a system’s memory usage my code produces what I call a “PM2200” [1] chart. The giants on whose shoulders I balance precariously [2] first... [More]

Factorise - For Your Eyes
As you might know I like maths, particularly algebra.
(If you’ve read
Another Neat Piece Of Algebra - Series Summation and
Hello, I’m Martin And I’m An Algebraic you do.) If there’s one thing I would be doing if I weren’t doing this [1] it might be teaching maths - but it would have to be at a level where algebra and calculus were substantial topics.
But I... [More]
