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 Displaying and Managing User Sessions.

Features

The application server display includes the following information:

· Server Name: name of the individual application server.

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

· Host: host name of the individual server

· Type: SAP Work Process type(s) for which an application server has been configured

As well as the familiar work process types Dialog, update (Update and Upd2), Enqueue, Batch and Spool, there is also the entry ICM. This means that on the application server in question an Internet Communication Manager (ICM) is configured that can accept or send requests from the Internet (HTTP and other protocols). For more information see Internet Communication Manager (ICM).

· Status: The possible statuses of an application server (initial, starting, active, passive, shutdown and stop) are described in Statuses of an SAP Application Server.

You can make changes to statuses in the Message Server Monitor (transaction SMMS). The possible functions are described below:

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

You can use your cursor to select an application server by clicking on the relevant line (except for the Refresh function). The function that is executed then refers to this server.
