System z9 and zSeries Technical Conference

(Originally posted 2006-01-12.)

I’m lucky to again be on the agenda at this conference. Here’s a link to the conference website.

This is a very good arena for technical education on the mainframe, with many great speakers from the development laboratories, coupled with a number from the field. I always learn a lot – so I highly recommend it.

My three presentations are:

MIDAWs, FICON and DB2 Performance

I’m thrilled that Jeff Berger asked me to present his paper. Here’s the abstract:

Martin will present Jeff Berger’s paper on how the new z9-109 MIDAW facility, FICON channels and the DS8000 controller can improve DB2’s I/O Performance. This presentation will cover Extended Format DB2 data sets, FICON Express 1 and 2, what MIDAWs are, the new DS8000 controller, and finally how all these have been shown in measurements to improve DB2 I/O performance.

Memory Performance Management in a 64-bit world

This one is an update on last year’s presentation of the same name. Here’s the abstract:

DB2 Version 7 exploits 64-bit real memory, whereas Version 8 also exploits 64-bit virtual. This presentation focuses on managing both real and virtual memory, with an emphasis on DB2. It enables z/OS and DB2 performance people to work together to manage both the real and virtual memory usage by DB2.

It assumes at least a basic understanding of how memory works on zSeries processors.

Tuning “New World” DB2 Applications for MVS Performance Specialists

Again an update on an ever-evolving theme:

MVS Performance specialists are used to handling the quirks of SMF records. They are therefore well placed to support DB2 Application tuning efforts.

This presentation introduces MVS Performance specialists to the DB2 SMF 101 Accounting Trace record, outlining many of its major quirks. Reference is made to other types of instrumentation that complement SMF 101.

After some “vocabulary and syntax” how records from different application types look is presented.
