About this Manual...

This document describes how to configure and install highly available R/3 systems on HP-UX 10.x and 11.x using MC/ServiceGuard. It refers to the HP product B7885BA - MC/SG Extension for SAP. To get further information regarding SAP and High Availability in general, please refer to the SAP documents:

To understand this document you have to have knowledge of the basic MC/ServiceGuard concepts and commands. Experience in the Basis Components of SAP R/3 will also be helpful.

This manual consists of three chapters:

Chapter 1, "Chapter 1 “Understanding MC/ServiceGuard Extension for SAP”," describes MC/ServiceGuard Extension for SAP R/3 (SGeSAP) concepts. It also explains the current approach and why it was taken. It can be used like a FAQ list. If you have technical questions about the installation, especially during the scoping phase, refer to this section to get the information you need.
Chapter 2, "Chapter 2 “Step by Step Installation Guide”," describes the installation of SGeSAP step-by-step down to the HP-UX command level.
Chapter 3, "Chapter 3 “SGeSAP Administration”," contains a summary of how to switch off SGeSAP. This is useful for very complex R/3 reconfiguration tasks like putting the R/3-System.
