Many Db2 environments rely on Tivoli System Automation (TSA) to manage High Availability Disaster Recovery (HADR) clusters. While TSA has long provided reliable automation for Db2 failover, modern Linux clustering standards and DevOps practices are increasingly shifting organizations toward Pacemaker-based cluster management and infrastructure automation.
This session presents a real-world migration approach for transitioning Db2 HADR environments from TSA to Pacemaker, while leveraging Ansible automation to standardize cluster deployment, configuration, and operational management.
Attendees will learn how to design a repeatable DevOps-driven framework that automates the provisioning of Pacemaker clusters, integrates Db2 HADR resources, and validates failover behavior across environments. The presentation will demonstrate how Ansible playbooks can be used to automate cluster setup, resource configuration, fencing policies, and operational testing, enabling consistent and scalable deployments.
The session will also highlight common challenges encountered during TSA-to-Pacemaker migrations, including cluster configuration pitfalls, resource dependencies, and operational considerations for maintaining availability during the transition.
By the end of the session, participants will gain practical guidance, automation patterns, and lessons learned for modernizing Db2 high-availability environments using Pacemaker and DevOps practices.
