04 Aug 2005 Protect your data using the High Availability Disaster Recovery feature of DB2® Universal Database™ (DB2 UDB). This article explains in detail how it works with SAP.
Introduction
In today’s world where businesses are serving customers from around the world on a 24x7 schedule, customers expect their computing systems to be 100% reliable. DB2 UDB has always been in the forefront of databases in providing such industrial strength reliability.
In DB2 UDB V8.2, DB2 introduced two new features that will further provide customers with options to implement High Availability and Disaster Recovery (HADR) and automatic Client Rerouting capabilities. These features protect the customers from a production downtime in the event of a local hardware failure or a catastrophic site failure by duplicating the workload of the database to a separate site. These features are shipped as part of the standard packaging of DB2 UDB ESE.
In this paper, we will show how these DB2 UDB features can be used with the world leading ERP software, SAP R/3 4.7 Enterprise. We will walk the reader through the steps necessary to set up both DB2 UDB for HADR and Client Reroute with SAP R/3 4.7 Enterprise.
Details of procedures and examples of output are provided for the reader to follow each step carefully and be able to compare with their own experience.
