The Application Server program is composed of two components: the Application Server service program and the shell program. During installation, the Application Server service program becomes integrated with the Windows Service Control Manager where it can be started and stopped like any other service. Optionally, the Application Server service program can be set to start automatically each time the Windows Server operating system starts (this is strongly recommended to ensure that the Application Server is always active and running). The Application Server shell program, used mainly for configuring the Application Server, can also be used to manually start and stop the Application Server.
