There are multiple options for having high availability with your DB2 databases:
- DB2 pureScale
- DB2 High Availability Disaster Recovery (HADR)
DB2 pureScale is a scale-out cluster feature with built-in high availability. DB2 pureScale provides virtually unlimited capacity, load balancing, high availability, continuous availability, and application transparency.
Alternatively, you can use the DB2 High Availability Disaster Recovery (HADR) feature, the DB2 Online Reorganization feature, and IBM Tivoli System Automation for Multiplatforms. HADR allows failover to a standby system in the event of a software or hardware failure on the primary system. Online Reorganization actively reconstructs the database table for better performance, while permitting uninterrupted access to the table data. Tivoli System Automation provides high availability by automatically transitioning to a standby DB2 database server.
Reduced data server down-time enables you to meet strict Service Level Agreements (SLAs) with no loss of data during infrastructure failures. Reliable data recovery allows continuous table access through disaster strikes. DB2 has easy administration with automatic failover co-ordination and hands-free control of IT infrastructure.
