Administration of the SAP Web DispatcherLocate this document in the navigation structure

Use

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

Prerequisites

The SAP Web Dispatcher must be installed.

Tasks

Below is a list of the most important administration tasks, which are performed as necessary:

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

Caution

When you set the maximum values, note that unnecessarily large values can increase the memory requirement of the SAP Web Dispatcher.

Example

You can find an example of an SAP Web Dispatcher's profile file in "Example: Profile File of a SAP Web Dispatcher".

More information about linking logon groups to the Web Dispatcher: "Assigning Logon Groups".

Administration & Monitoring

You can use the Web administration interface to administrate, monitor, and set traces in, the SAP Web Dispatcher.

Alternatively, you can access the Web Dispatcher administration and monitoring functions from the command line.

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).

If you are working with the System Landscape Directory, you can register the Web Dispatcher in this.

Modification of HTTP requests

You can configure the Web Dispatcher so that it modifies incoming HTTP requests before it forwards them to the application server.

You can manipulate header fields, filter (reject) specific requests, rewrite URLs, and so on.

You can find more information under Modifications of HTTP Requests.

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.

Handling HTTPS requests

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

  • End-to-End SSL

  • Decrypts them and forwards them unencrypted

  • Decrypt and encrypt them again

These options are described in SAP Web Dispatcher and SSL.

You can find information about SSL configuration in SDN at http://www.sdn.sap.com/irj/sdn/howtoguidesInformation published on SAP site under Web Application Server.

Setting up error handling

You can configure the behavior of the SAP Web Dispatcher when responding to errors. More information: Background Processing.

High availability

SAP Web Dispatcher can be configured for high availability.
