Join us for an insightful discussion on 4 November, 2025 at 11:00 AM ET. Starting in Db2 version 12.1.0, Pacemaker has replaced Tivoli System Automation & MultiPlatforms (a.k.a. TSA) as the integrated cluster manager for Db2 pureScale on Linux. In these Pacemaker-managed clusters, the concept of quorum is vital to maintaining data consistency, preventing split‑brain scenarios, and ensuring correct failover behaviour. This webinar dives into how Pacemaker uses quorum mechanisms to evaluate cluster health and host availability, exploring the rules and policies that govern the correct recovery operations performed during failure scenarios. We will discuss the different quorum policies available in a Db2 pureScale cluster, monitoring the quorum state, and the fencing mechanism. At the end of the presentation, a real network failure scenario will paint a clear picture of quorum in action and illustrate how the cluster recovers safely.
