As organizations strive to do more with less, IBM DB2 for Linux, UNIX, and Windows provides various built-in high availability features. DB2 further provides high availability solutions by leveraging enterprise system resources with broad support for clustering software such as HACMP, TSA, and Microsoft Windows Cluster Server.

This IBM Redbooks publication describes DB2’s high availability functions and features, focusing on High Availability Disaster Recovery (HADR) in the OLTP environment. The book provides a detailed discussion of HADR, including setup, configuration. administration, monitoring, and best practices.

We explain how to configure cluster software HACMP, TSA, and MSCS with DB2 and show how to use these products to automate HADR takeover.

DB2 also provides unprecedented enterprise-class scalability to 32-bit and 64-bit Linux, UNIX, and Windows platforms. We introduce the DB2 Database Partitioning Feature, covering the installation, configuration, and scaling of a database partition.
