Many of today's corporations run their businesses on the SAP R/3 application suite. High availability of these applications to the user community is essential. Downtime means lost sales, profits and worse. The combination of SAP R/3 and Microsoft Cluster Server is an important element in providing the required access to key business applications.
This book will help you plan and install SAP R/3 4.5B in a Microsoft Cluster Server environment running Microsoft Windows NT 4.0 and Windows 2000. Installation procedures complement the existing SAP documentation and cover the integration of the three major database management systems: Oracle, DB2 and SQL Server.
The first three chapters introduce high availability and clustering and how these concepts apply to SAP R/3 environments. Chapter 4 describes planning needed before implementing a clustered SAP R/3 configuration. Discussions include certification of hardware and software components, server sizing, disk layout, and network configurations. SAP R/3 and Windows 2000 are also discussed. The installation part of the book is a step-by-step set of instructions to lead the reader through the process of installing SAP R/3, Microsoft Cluster Server and the particular database you choose to install, Oracle, DB2 or SQL Server. How to configure an SAP backbone network is also described. The remaining two chapters describe how to tune your SAP R/3 configuration, how to verify your installation is working correctly and where to look if you have problems.
This book should be especially helpful to people who are involved with planning or installing SAP R/3 in a Microsoft Cluster Server environment. Such people will often be technical planners and IT managers in user organizations who need to understand the requirements of such an installation, IT professionals or consultants who need to install SAP R/3 in an MSCS environment, and experienced SAP R/3 professionals who need to understand the ramifications of clustering on SAP R/3 and how to implement such a solution.
