Start and stop

Operating the SAP Web Dispatcher describes how you start and stop the SAP Web dispatcher. Here you will also find the prerequisites for operating the SAP Web Dispatcher.

Parameterization/configuration

SAP Web Dispatcher Profile Parameters describes the profile parameters for configuring the SAP Web dispatcher. The settings should be appropriate for normal operation.

When you set the maximum values, note that unnecessarily large values can increase the Memory Requirement of the SAP Web Dispatchers.

You can find an example of a SAP Web Dispatcher’s profile file in Example Profile File of the SAP Web Dispatcher.

For information about linking logon groups to the Web dispatcher see Assigning Logon Groups.

Configuring the SAP Web Dispatcher / Message Server for Virtual Hosts explains how you have to configure the SAP Web dispatcher for compliance with virtual hosts.

Administration & Monitoring

You can use the Web administration interface to administrate, monitor, and set traces in, the SAP Web Dispatcher. The process is described in the section Using the Web Administration Interface.

Alternatively, you can access the  Web dispatcher administration and monitoring functions from the command line. For more information see Using the Command Line Programs icmon and wdispmon.

You should only use these if you have problems with the Web administration.

You can also send operating system signals to the SAP Web Dispatcher. This can be useful if you want to execute functions in shell script. The SAP Web Dispatcher knows the same signals as the Internet Communication Manager (ICM). For details see Using Signals to Control the ICM.

Communication with the message server / application server using SSL

You can make the exchange of metadata with the message server and application servers secure by encrypting the data with SSL. For information see Meta Data Exchange Using SSL.

Handling HTTPS requests

The SAP Web dispatcher can handle HTTPS requests in different ways:

●      End-to-End SSL

●      Decrypt them and forwards them unencrypted

●      Decrypt and encrypt them again

These options are described in SAP Web Dispatcher and SSL.

For information about SSL configuration of the Web dispatcher see Configuring SAP Web Dispatcher to Support SSL, and the How-to Guide on the SAP Service Marketplace http://service.sap.com/nw-howtoguides under Web Application Server.  

Setting up error handling

You can configure the behavior of the SAP Web Dispatcher when responding to errors. For information, see Background Processing.
