IDUG EMEA 2026

This session will be about bridging existing legacy programs with "modern"interfaces, such as the Unix shell and Ansible. Next-generation mainframers are typically well-versed in Unix shells and scripting, largely due to Linux's dominance in the server market. But how does this apply to traditional mainframe tools? That is what we want to show you.

Enterprise database migrations are often slowed to a crawl by their reliance on flat files. Large volumes of data must be written to disk, moved across networks, and reloaded using traditional utilities—a process that is time‑consuming, storage‑intensive, and error-prone. In migrating a legacy Oracle environment on AWS RDS to a modern, containerized Db2 platform running on OpenShift, it became clear that a fundamentally different approach was needed—one that removes the disk from the equation altogether.
This session presents a high‑performance, zero‑disk migration approach that streams data directly from the Oracle source into Db2. It walks through how to set up Db2 Federation and automate nickname creation to establish a direct data pipeline. Rather than relying on conventional SQL processing, the approach feeds a federated cursor straight into the Db2 LOAD mechanism, allowing data to be written directly into target tables with maximum efficiency.
To make this solution practical at

Db2 LUW provides the capability to create partitioned tables which have a number of useful benefits. However, a current downside to the implementation on LUW is that there is no automatic built-in functionality to add partitions when needed or manage the process of adding, detaching and deleting partitions. In particular, for Production environments that require stability and availability without interruption, robust and auditable management of partitions is a critical and invaluable requirement.
In this session I will provide an overview of the design and implementation of a bespoke Unix based solution used in a high volume 24/7 transactional and warehouse database application. The presentation will include an explanation of the requirements to manage table partitions in a Production environment and will include high level diagrams of the process flow to manage the partitions; the logic to identify required partitions/timestamps to manipulate, the required commands to make changes,
