Integrated solution using Pacemaker
Pacemaker is an open-source, high availability cluster manager software integrated with Db2® Advanced Edition and Db2 Standard Edition on Linux®.
It provides high availability and disaster recovery capabilities for on-premises deployments and non-container cloud environments, such as Amazon Web Service (AWS). This integrated solution supports multiple databases and multiple instances, as configured using the Db2 cluster manager utility (db2cm).
In Db2 11.5.5 and later, HADR automation is supported with Pacemaker as the cluster manager. This includes supporting automation for multiple HADR databases per instance and also supporting automation of multiple HADR instances all within one common Pacemaker/Corosync cluster.
