When you start SAP NetWeaver, you start the system database, the application servers, and the respective processes of which the system consists.
In general, the database starts first, and then the instance. When you start the central instance, the database starts automatically. However, the database does not stop when you stop the central instance.
The following sections describe how you start and stop SAP NetWeaver ABAP and Java. The procedures assume a central system that consists of a database and a central instance (ABAP, Java) on a single host.
● Starting and Stopping SAP NetWeaver ABAP Under Microsoft Windows
● Starting and Stopping SAP NetWeaver Java Under Microsoft Windows
