Use

You can display a list of application servers that have registered themselves with the SAP message server by executing Transaction SM51, or by choosing Monitor ® System monitoring ® Servers. Only these application servers are active in an SAP System.

Further, you can also manage, and display the status, of the users and work process in all application servers belonging to the SAP System.

Integration

The function for managing users and work processes corresponds to the user- and process-tools. For more information, see Displaying and Controlling Work Processes and Display and Manage User Sessions.

Features

The application server display includes the following information:

The name usually consists of the host name, the SAP System name, and the SAP System number.

Besides the known work process types Dialog, Update and Upd2, Enqueue, Batch and Spool, there is also the entry ICM. This means that an Internet Communication Manager (ICM) is configured on the application server in question. This ICM accepts and sends requests from the Internet (via HTTP or other protocols). For documentation on this, see Structure linkSAP Web Application Server.

State: the possible states of an application server (initial, starting, active, passive, shutdown and stop) are described under States of an SAP Application Server.

Note

See the Message Server Monitor (transaction SMMS) for information on changes to these states. The possible functions are described below.

The following functions are available as pushbuttons or in the menu:
