Db2 high availability disaster recovery (HADR)

Db2® on Cloud Pak for Data supports Db2 high availability disaster recovery (HADR) to protect against data loss on various topologies, including primary and standby on the same or different Red Hat® OpenShift® clusters and within the same or different projects (namespaces).

HADR provides a high availability solution for both partial and complete site failures by replicating data changes from a source database, called the primary database, to the target databases, called the standby databases. Db2 on Cloud Pak for Data supports a single remote standby server.

Before you begin: To set up a Db2 HADR configuration on Cloud Pak for Data, you must install and deploy two Db2 database services that are at the same release level.

For full HADR documentation, see High availability disaster recovery (HADR).
