HADR (High Availability Disaster Recovery) is a Db2 LUW feature for high availability and disaster recovery. It is the preferred solution for HA and DR on Db2. It replicates data in real time from a primary database to one or more standby databases. In case the primary database fails, a standby database takes over as the new primary. Integrated cluster manager can be enabled for automated failover. Reads on standby can be enabled. Multiple standbys are supported since V10.1.
