Rumor has it that www.ibmdatabasemag.com will be going off the air on 30 April 2009. We are sad to see this valuable resource to the IBM Database community go.

Hundreds of database professionals from around the world have driven thousands and thousands of hits to the DB2 LUW Performance blog series. The good news is that we have preserved this valuable content and reference material on our site for your continued reference and benefit. You can find the blogs at:

It was about a year ago that a DBA in Sydney Australia asked me if I knew of a way to correlate database tuning efforts to Energy savings. IBM's Smarter Planet campaign gave me renewed inspiration to research this important topic, for the fourth pillar of Smarter Planet involves seeking new ways to improve efficiency and lower costs of existing processes. What you are about to learn might be a real eye opener.

I pushed my father in a wheel chair for the first time last month. As I looked at the man who was my Scout Master, who helped me achieve Eagle rank, who taught me to bowl, and inspired me with strong core values of helpfulness and community service, these wheel chair excursions marked a pivotal inspiration point for contemplating my own current health, and have given rise to my own self-improvement goals that you can read about in my personal blog. This year's new IDUG presentations and Ed Seminars will also include new information on DB2 Health monitoring. So, in this blog post, let's look into the health and fitness of your databases.

I was recently contacted by a DBA at a large insurance company. After upgrading from DB2 V8.2 to 9.1.0.3, the DBA activated the Self Tuning Memory Manager (STMM) in the hope that it would solve all performance woes. To the contrary, performance got worse, and the DBA noted a marked increase in SORT overflows. He even opened a PMR with IBM. But this isn't a case of STMM gone crazy; something else is going on, but what? Let's take a look at the numbers and discover the truth.

Congratulations to the IDUG Europe Conference Planning Committee (CPC)! IDUG Europe 2008 was one of the best IDUG conferences ever! On 17 October 2008, I taught the one day Ed Seminar "DB2 LUW Performance Diagnosis Learning Lab." This post contains a review of one of the participant's data and findings. The data comes from a busy production database that runs a banking application.
