Db2 for z/OS Performance Traces Part 1 - Intro, Accounting, and Audit

When it comes to Db2 for z/OS performance management, one of the first things you need to understand is the traces that are available that must be started in order to cause Db2 to track performance metrics.

Db2 for z/OS Buffer Pools: Index Root Pages and the Data Management Threshold

Sometimes, a change in the way Db2 for z/OS manages its resources is introduced, and the change "flies under the radar" (i.e, it escapes the notice of most Db2 users) because it is relatively small in terms of scope and impact and is not widely highlighted in the product documentation, and it delivers the intended benefit (e.g., enhances CPU efficiency for data access) and no one thinks about it -- BUT, it may have a consequence that pops up in a surprising way, causing, initially, some...

I was recently asked about the Db2 zparm, NPGTHRSH. Admittedly, I knew little about it. The first place I always go to learn about zparms is the Db2 installation and migration manual. Unfortunately, the manual wasn't much help in this case. So I did some searching and found this IBM Redbook: "Db2 12 for z Optimizer."

The Db2 12 for z/OS Blog Series - Part 22: Function Levels 501 and 502 (Continuous Delivery)

If you have heard anything about Db2 Version 12 chances are that you have heard about continuous delivery. Instead of waiting 2 to 3 years for a new version of Db2 to be released, new functionality will be continuously delivered on a regular basis. The idea is to bring Db2 into the modern age of development practices where releases are small and quick, instead of large and slow. So instead of...

Improving Performance by Caching Select Statement Results

A significant trend in the database world these days is moving more data management and processing into memory. If you can bypass disk I/O you can achieve tremendous performance gains. There are many reasons for this, but of course, the most important reason is that disk access is much slower than memory access. It is orders of magnitude more efficient to access data from computer memory than it...
