IDUG EMEA 2026

As cyber threats grow increasingly sophisticated, ensuring the security of Db2 for z/OS environments is critical to protecting sensitive data and maintaining compliance. This presentation explores a comprehensive security assessment designed to identify vulnerabilities, evaluate access controls, and strengthen configurations. Experts with extensive mainframe experience will review key elements such as grants and permissions, DSNZPARMs, audit policies, and DDF settings, providing detailed findings and actionable recommendations. Attendees will gain insights into optimizing user privileges, securing data, while also preparing for an easier transition to external security. Enhance your security posture and mitigate risks with proven strategies tailored to Db2 for z/OS.

Warehouse and data lakehouses are converging and Db2 is ready for this shift. Db2 Datalake tables enable access to open-format data stored on remote object storage directly from within the relational database, eliminating the need for complex ETL pipelines or data duplication. This session explores the technical architecture supporting both Hive (ODF) and Iceberg table formats, demonstrating how organizations can query PARQUET, ORC, AVRO, and TEXTFILE data alongside traditional Db2 tables in complex SQL queries while maintaining ACID properties where needed. Attendees will learn implementation strategies for converged warehouse architectures, performance optimization techniques, and real-world use cases where Datalake tables provide bidirectional data flow between relational databases and data lake / lakehouses.

This session is about deep dive technical details of how Z data is integrated with other platforms and solutions.
This is an architectural, use case and product level technical session. There will be latest news from the zSW Development and Product Management in the context of Data Management, focused on Db2 for z/OS.
The goal of this session is

The presentation is aiming to explore the introduction and evolution of Fast Traversal Blocks (FTB) in IBM Db2 for z/OS, focusing on the initial implementation in Db2 12 and the subsequent enhancements delivered in Db2 13.
The session will outline the architectural concepts behind FTB, key eligibility criteria, and the functional improvements introduced in Db2 13 for z/OS. The major focus of the presentation will be a real-world case study from GarantiBBVA, highlighting their experience implementing FTB in their Db2 for z/OS systems. This includes practical insights into planning, configuration, and deployment strategies, as well as challenges encountered and lessons learned during adoption. It will also examine how to identify suitable indexes for FTB and the tangible benefits of FTB usage at GarantiBBVA. The session will also be aiming to demonstrate how to measure and validate performance improvements using key metrics, system statistics, and monitoring tools. By combining theoreti

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.

This session explores backup and recovery strategies for Db2 for z/OS, emphasizing the critical importance of compliance and recoverability in today’s data-driven world. Attendees will learn about various backup types, tools, and recovery processes, with a focus on creating resilient systems that align with modern compliance requirements. Through use cases, the session will demonstrate how to ensure recoverability, data integrity, minimize downtime, and maintain availability.
