D2 Bridging Relational and Data Lake Architectures: Db2 Datalake Tables
Monday September 28, 2026 11:30am - 12:30pm BST

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.

Monday September 28, 2026 11:30am - 12:30pm BST
Luis
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.

I've gained a lot of experience in this area, which I'd like to share. I'll describe the environment with replications between Db2 z/OS and Db2 LUW. For which use cases is the tool suitable, and for which is it less appropriate? What problems have we encountered, and what workarounds have we found?

A3 What’s New in Db2 for z/OS Performance
Monday September 28, 2026 2:00pm - 3:00pm BST
Infante
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.

The ones that should probably not be running anymore
The ones that fail too often

D3 Underrated ITC Tables in Db2
Monday September 28, 2026 2:00pm - 3:00pm BST
Maria
Insert Time Clustering (ITC) tables are not an obscure feature in Db2 - many practitioners know them, and they do appear in logging, event, and similar append-oriented workloads. However, their practical design space is often underestimated, especially when the discussion stays at a high level and does not go into physical organization and concurrency details.
This session looks at ITC as a technical design choice rather than a theoretical table attribute. I will briefly position ITC within the Db2 table organization family and then focus on the internals that matter in practice: its MDC-derived physical layout, insert behavior, extent reuse, ordered access to rows in their natural arrival sequence, and the locking patterns taken on pages and extents during insert, scan, and processing activity. These details are not just implementation trivia - they directly determine whether ITC is a good fit for a given workload.
The talk will compare ITC with APPEND mode for FIFO-style patterns suc

E5 Power-Up for Db2: A Guide to Modernizing Administration with Python and Ansible
Monday September 28, 2026 4:30pm - 5:30pm BST
Luis
As Db2 environments grow in complexity, traditional shell scripting often reaches its limits in maintainability and modern DevOps integration. This session serves as a high-level roadmap for Db2 administrators and developers to leverage Python and Ansible for modernizing their daily workflows. We will explore foundational database connectivity using the ibm_db driver and demonstrate how to transition from static text logs to interactive analysis using Pandas for efficient data wrangling and visualization. By utilizing modern tools like Jupyter Notebooks for exploration and Visual Studio Code for development, we will discuss the benefits of Object-Oriented Programming (OOP) in creating modular, reusable connector classes. Finally, the presentation dives into the DevOps world, showing how to extend Ansiblethrough custom filter, action, and lookup plugins to build flexible, database-driven automation frameworks.

The reorganization of a DB2 tablespace is primarily performed to optimize access path performance, but it also constitutes a critical database maintenance operation. This presentation will cover our experience as users following a sudden increase in the number of partitions in partition-by-growth tablespaces after executing partition-level REORGs, as well as the approach we took to address the issue.
