Starting and Stopping SAP Systems and
Instances 
When you start the SAP System, you simultaneously start the system database, the application server and the respective processes of which the system consists. In the simplest case, an SAP System consists of only a database and a single application server.
There are different processes, depending on the type of SAP system:
A
start profile
defines which processes are to be started or stopped. This
profile is
automatically generated during the system installation. You can change it
later.
You can start and stop the SAP System and its database using operating system tools. There are special scripts available to do this, or you can use the appropriate program icons.
You can start and stop SAP instances with the Computing Center Management System (CCMS). The prerequisite for doing this is that the database and at least one SAP instance have been started.
