Motivation for the NW 7.1 Architecture

SAP was motivated to address these constraints in the NW 7.1 release. SAP PI 7.1 is one example of a SAP solution that is available for general use using NW 7.1 architecture. Some of the key new architecture improvements with the NW 7.1–based SAP business applications are as follows:

• Separation of yet-to-be-processed user requests from in-process user requests by using fast channel architecture (FCA).

• Real-time monitoring of Java processes with new and improved SAP Management Console (SAP MC).

• SAP Memory Analyzer tool to help better identify the root cause of the server process crashes.

• SAP developed its own Java SE 5–compliant JVM, referred to as SAP JVM.

Let us now study the SAP cluster architecture in NW 7.1, with an emphasis on the new improvements for making SAP NW AS Java more robust.
