IDUG NA 2026

Come to listen to the architects of Db2 for z/OS explain overall strategy, review recent new features delivered in Db2 and also take a look at the future - where Db2 is going and why. We will talk about planning for the next version and you will learn what you need to know and actions you should start to take now to prepare for the future of IBM's flagship database.

Db2 for z/OS continues to advance through continuous delivery, introducing functional and performance enhancements that improves application availability, compatibility and operational efficiency. Effectively exploiting these capabilities requires understanding not only what has changed, but how the changes interact with workloads, subsystem configuration, and the underlying IBM Z platform.
This session provides a technical deep dive into recent Db2 for z/OS feature enhancements, and how these updates influence performance areas such as CPU consumption, concurrency behavior, and subsystem scalability. It will cover applicable monitoring and instrumentation updates and guide the tuning decisions.
Attendees will leave with concrete technical guidance, exploitation considerations, and best practices for applying recent Db2 for z/OS enhancements.

There have been several useful enhancements made in Db2 for z/OS utilities in recent years. This session will explain what has been delivered and how best to take advantage of these new features. We will also provide some insight into future plans leading up to the next version of Db2.

Make sure you have all the tools to write functional SQL using all the features of recent versions of Db2. Stop writing SQL like it's the '90s.

This session will share experience from client studies and engagements: sharing proven recommended best practice; learning good, bad and ugly; providing answers ti important, frqeeunt or difficuly questions. This session will cover the following topics: Complacency about component failure and ability to absorb workload failover in a dat asharing environment; missed opportinity for elapsed time performance improvementnfor skip sequnetial batch processing; misteps in evaluating the performance benenfit of CICS-Db2 thread reuse and RELEASE(DEALLOCATE); SQL coding to avoid update anomaly when using cursor stability isolation; misadventures when using High Performance DBATs;monitoring WLM policy achievement; options for mass data recovery following logical data recovery and data loss; performance issue with remote DDF batch workload; tuning ogf GBPs; thorough Disaster Restart testing.

Interested in exploring IBM SQL Data Insights without the effort of installing it on your system or building models from scratch? This session introduces Industry Starter Kits designed to help Db2 for z/OS users quickly evaluate and experience the power of AI-driven insights using pre-built models, sample industry data, and ready-to-run AI queries.
The session features real-world use cases across industries such as finance and insurance, demonstrating how SQL Data Insights can analyze Db2 table data to uncover hidden relationships, detect anomalies, identify unusual transactions, and generate meaningful business insights that may be difficult to find using traditional SQL techniques alone. Attendees will learn how to deploy and load pre-built AI models, execute AI-driven SQL queries, and understand and interpret the results returned by those queries using familiar Db2 workflows and interfaces.
By walking through the industry use cases included in the starter kits, attendees will gain a clearer understanding of what SQL Data Insights is capable of and how AI-driven SQL analysis can be applied to their own Db2 environments. The session is intended to spark ideas for new use cases and help users envision how their existing Db2 data can be analyzed in entirely new ways.
Whether you are new to SQL Data Insights or looking for an easier way to get started, this session provides a practical, hands-on approach to jump-starting your AI journey on Db2 for z/OS.

There have been so many enhancements in Db2 SQL for developers in the last 3 or 4 versions that many developers have never really taken advantage of. This presentation picks my personal favorites that I believe all developers should get knowledgeable on and possibly applied to current and future applications. Developers should be informed of all of newer features in Db2 and this presentation is a great summary for this topic. When it comes to performance, often times the answer to better performance is rewriting queries different ways, and redesigning programs differently. Attendees will leave with a better understanding of some great SQL enhancements, application table designs, along with getting stronger in the SQL language. This is a great session for developers on Db2 LUW or Db2 z/OS. Developers 'Get Empowered'.

Are you, and all of your sub-systems, ready for Db2 vNext that is coming to an enterprise near you soon? Are you aware that you cannot even get to Db2 13 FL511 if you have any of the specially announced “deprecated” items that we all have hanging around? Do you have a plan to get you out of this mess?
This session explains how you can find all the migration blockers that exist in your system and how to fix nearly all of them as well. It will also delve into VTAM/SNA and workfile usage to round off everything that can bite you!
