Working with event handlers

MPX has an event transmitter that must be installed on the same computer as the Server. In addition, the Message Broker can be installed on the same or another computer, depending on your needs. If you install the Message Broker, Unicast On-site event displays in the Event Handlers tab of the Configure Server dialog box.

For more information about MPX, its XML files, properties, and values, see MPX installation and configuration. The following topic describes how to work with event handlers. The Event Handlers tab provides a simple interface for editing the EventTransmitter.XML files.

This section describes how to assign default event handlers for servers and clients.

To assign the event handlers:

1. Open the Server Administration tool and select the server configuration.
   
2. Click Tools > Administration > Configure Server.
   The Configure Server page opens.
3. Select the Event Handlers tab.
4. Select an existing event handler.

5. Click one or both of the following:

   Server Default	Makes the selected profile the profile for the server. A server icon displays in front of the default server profile.
   Client Default	Makes the selected profile the default profile for clients. A green check mark displays in front of the default client profile. As users create server descriptions on their workstations, the profile selection defaults initially to this profile. Users can change from the default to another existing profile. If a profile is both the server and client default, you see only the server icon.
