SAP with Microsoft SQL Server 2005: Best Practices for High Availability, Maximum Performance, and Scalability24
SAP process overview
The sample in Figure 9 lists the different processes in one SAP instance. The sample does not show the Dispatcher, message server, or gateway processes.
One specific SAP NetWeaver Application Server instance represents a collection of processes. Most SAP services are realized using different processes. The NetWeaver Application Server Layer can be distributed over several servers to perform processes. In this case, different instances of SAP NetWeaver Application Server can be configured differently, based on the user or job assignments to those instances.
SAP NetWeaver Application Server instances can be configured to enable only one or two types of processes or nearly all types of processes. The specific configuration depends on the size of the SAP system and on the available hardware.
