IDUG EMEA 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.

Customers are constantly striving to perform essential DBA related tasks being driven by application improvements and evolutions. Non-Disruptive schema changes have been a major objective for the Db2 for z/OS ecosystem. Db2 will discontinue to support several legacy table space types and deprecated functions. Organizations must migrate to Universal Table Spaces (UTS) and remove unsupported functions prior to the deadline to ensure long‑term database viability. In addition to user‑defined objects, the work file database and many Db2 catalog tables that reside in deprecated table spaces must also be considered in the migration plan. This session highlights the invaluable online schema enhancement features in Db2 that can be exploited to achieve the highest level of availability.

Db2 for z/OS continues to advance through Db2 13 continuous delivery, introducing performance‑focused enhancements that impact SQL execution, system scalability, resource efficiency, and operational behavior. 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 performance enhancements, including features delivered through Db2 13 continuous delivery and insights gained from real customer experiences. We will examine how these updates influence critical performance areas such as CPU consumption, concurrency behavior, and subsystem scalability.
In addition, we will cover monitoring and instrumentation updates, discussing how to interpret new or enhanced metrics and how they can be used to validate performance behavior and guide tuning decisions.

These two tables, SYSUTILITIES and SYSOBJECTEVENTS, have really became part of my daily inputs since the moment they arrive to my systems.
They are recording all the movements related to utilities in your system, so let's start deep diving on them :
Which ones are the most CPU consuming
The more time consuming
The ones that should probably not be running anymore
The ones that fail too often
The time slots when most of them are running
And how to use the information they provide to improve your system.

Stuck on a tough audit level? Tired of seeing the "Game Over" screen when a report asks: "Who had access three months ago?" Many Db2 sites rely on clunky log tools for this security quest. Get ready to discover the secret power-ups! We'll expose the relatively new, native Db2 security information stored right in the catalog—the hidden cheat code you need. Join us to unlock these features, score a Pixel Perfect audit, and conquer your compliance quest by augmenting your current processes. No extra quarters needed!
