More Fun With DDF

(Originally posted 2016-05-16.)

Already this year I’ve posted thrice on DDF:

• DB2 DDF Transaction Rates Without Tears
• DDF Batch
• DDF Counts

It’s clearly something that’s important to me right now. 🙂

So this post is to mention I’m putting the finishing touches to a new presentation (the third of the year so far). I’m giving it to European customers in Munich in mid June. I’m also giving it as an internal IBM webcast in the same timeframe. Of course, I hope to use it again and again.

It’s called “More Fun With DDF”.

The basic thesis is there’s lot of interesting analysis to do for DDF workloads at a number of levels:

• System
• WLM Service Class
• DB2 Subsystem address spaces
• DB2 Accounting Trace

Obviously you can’t do analysis without data and it is indeed there aplenty.

So after what I’m calling a Tutorial I dive into a number of customer cases. While I’ve been using them as test data (for my rapidly evolving code) they do illustrate a number of points. None of the cases are exactly “war stories” but I do think they’re interesting.

And after this presentation it’s on to “refurbishing” an older presentation.

But for now previously unthought of slides are popping into my head (and hence into the presentation) at a rate of about 1 a day; I’m well past the “I can’t fill an hour” stage. 🙂 I just hope it is more fun. 🙂
