IDUG EMEA 2024

Alas! We are in the Final Act of the transition from TSA to Pacemaker on Linux! This finale is a culmination of 4+ years of intense development kicked off with a technical preview of 2-node HADR in v11.5.4.0 as the Prologue, followed by Act 1 with the official GA five months later in v11.5.5.0. Act 2 boosted up & running story with integrated bundling of the Pacemaker stack in v11.5.6.0. Act 3 covered v11.5.7.0 and v11.5.8.0 where the automation on cloud was introduced as well as the debut of the second HA configuration - Mutual Failover with shared disk. This session serves as a refresher of HADR and Mutual Failover and an introduction to DPF and pureScale with Pacemaker. It covers the "WHY" it is time to switch to Pacemaker, the "WHAT" you should know before you switch, the "HOW" you can switch, the "WHAT IF" you do not switch, and "WHAT ELSE" is in the pipeline from Db2 High Availability Development.
