PD and Best Practices for Db2 HADR Replay and Presentation

Db2 HADR (High Availability Disaster Recovery) is a Db2 LUW feature for high availability and disaster recovery. In case of fatal error on primary, the HADR can failover to standby, making it new primary to achieve HA (High Availability). Only in PEER state, the failover operation can be done without data loss. Therefore, it is vital for the HADR standby host to keep up with primary host and stay in PEER state, to allow a fast and smooth failover. To achieve this goal, there are two major parts. First is that the standby needs to quickly catch up to primary from a behind position to reach PEER state. Second is that the standby needs to maintain the PEER state as long as possible, even when stressed with high volumes of workloads. In this talk, we'll go over the tools to monitor HADR health and the best practices for HADR in various scenarios.
