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.

In Db2 11.5.8 and later, Mutual Failover (MF) automation is supported with Pacemaker as the cluster manager.

Important: In Db2 11.5.8 and later, Mutual Failover high availability is supported when using Pacemaker as the integrated cluster manager. In Db2 11.5.6 and later, the Pacemaker cluster manager for automated fail-over to HADR standby databases is packaged and installed with Db2. In Db2 11.5.5, Pacemaker is included and available for production environments. In Db2 11.5.4, Pacemaker is included as a technology preview only, for development, test, and proof-of-concept environments.

Note: The Pacemaker src.rpm (zip) file is packaged in the Db2 install media, and can be found in : <media_dir>/db2/pcmk/Linux/SRPMS. For example:

/tmp/server/db2/linuxamd64/pcmk/Linux/SRPMS/SRPMS.zip
