Management of the SAP Web Dispatcher

This documentation describes how to configure and administrate the SAP Web Dispatcher.

Architecture

For information on the architecture and functions of the SAP Web Dispatcher see Architecture of the SAP Web Dispatcher.

Prerequisites

The SAP Web dispatcher must be installed. For information about installing it see Operation of the SAP Web Dispatcher: Importing the SAP Web Dispatcher.

Tasks

The table below lists the most important administration tasks.

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

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.

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 and 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 Monitoring the SAP Web Dispatcher.

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.

Configuration for Using Virtual Hosts

Configuring SAP Web Dispatcher / Message Server for Virtual Hosts explains what you have to configure in the Web dispatcher or message server so you can use Virtual Hosts.

Using operating system signals

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.

Setting up error handling

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

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.
