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.

High Performance DBATs (HP DBATS) is a very important performance feature of Db2 for DDF workloads. If applied and used intelligently this feature can generate significant savings in CPU resource consumption. This session will cover the following topics: what is a connection?; what is a DBAT (THREAD)?; thread (DBAT) pooling and DRDA inactive connections; what are High Performance DBATs; good candidate application workloads for High Performance DBATs; general guidance for configuring High Performance DBATs; performance metrics and monitoring; WLM and High Performance DBATs; Issues; Summary.

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.

Enterprises are under pressure to deliver faster insights and streamline operations - the ultimate Boss Fight of managing large Db2 for z/OS environments. Generative AI is your new power-up for development and administration and your secret weapon against complexity. This session will show how to flip on the Auto-Pilot to tune SQL with expert-level precision, master complex schema management, and drive utilities intelligently for object maintenance. We'll walk through real speedruns (use cases) that demonstrate how GenAI simplifies workloads, cuts troubleshooting time, and improves efficiency, giving your team the cheat codes to unlock Db2's full value and achieve the High Score in productivity.

Db2 group buffer pools are an important component of a Db2 for z/OS datasharing environment. They help to insure data consistency across members of aDb2 data sharing group.As such, group buffer pool interactions represent additional work that Db2 hasto perform in a data sharing environment, and are one of the main contributorsof Db2 data sharing overhead.Therefore, from a performance perspective it is important that your group bufferpools are in good shape.This session will introduce group buffer pool concepts, but focusses on how tomonitor group buffer pool performance, the available options and metrics touse.
