Managing highly available database environments requires more than automated failover—it demands continuous validation, proactive monitoring, and simplified operations. Db2 12.1.5 introduces a powerful set of high availability enhancements that not only strengthen HADR and pureScale deployments, but also advance the journey toward autonomous operations through new Smart HA capabilities in Genius Hub.
 
In this webinar, we'll showcase the latest Smart HA agents that help administrators proactively assess the health of Db2 pureScale clusters using comprehensive diagnostics, Remote OS APIs, and SMAP-guided validation. Learn how the new health-check framework automatically validates cluster configuration and status by analyzing Db2 instance health, cluster manager alerts, domain topology, and quorum configuration. See how Genius Hub can identify failed members, Cluster Caching Facility (CF) connectivity issues, quorum problems, and other potential risks before they impact availability. 
We'll also cover the key high availability innovations introduced in Db2 12.1.5 that simplify deployment and operations for Pacemaker-managed environments. These include Route 53 DNS-based failover automation for HADR deployments on AWS, automated tiebreaker policy management for quorum-based HADR clusters, a new disk-based tiebreaker option for Db2 pureScale that reduces infrastructure costs, enhanced node-fencing through SBD integration, significantly faster rolling maintenance windows, and faster virtual IP failover during HADR takeover events. Additionally, we'll highlight new AIX 7.3 TL4 support for Db2 pureScale deployments. 

Together, these enhancements deliver a smarter, more resilient, and easier-to-manage high availability platform for mission-critical Db2 workloads.
