What is DB2 Active-Passive Cluster?

A DB2 Active-Passive Cluster is a high-availability setup designed to ensure minimal downtime and continuous database availability in the event of a failure. In this configuration, the active node handles all database transactions, while the other node, the passive node, remains on standby, ready to take over operations if the active node fails.

This architecture includes key features such as:

• Heartbeat Monitoring to detect failures in real time.

• Automatic Failover to the passive node, ensuring uninterrupted service without manual intervention.

• Replication Support, both synchronous and asynchronous, to maintain data consistency.

• High Availability and Disaster Recovery (HADR) capabilities to reduce data loss and operational risk during outages or disasters.

By implementing a DB2 Active-Passive Cluster, organizations can maintain robust database operations even under unexpected hardware or software disruptions.
