Parameterization of the SAP Web Dispatcher 

Use

The following sections describe the profile parameters of the SAP Web Dispatcher.

The default values are selected so that you do not have to make any changes to these parameters. You determine the point of access to your SAP system using parameter icm/server_port_<xx>. You can also use this parameter to bind the SAP Web Dispatcher to an IP address or interface only.

You can however use the parameters to adapt the configuration to specific system requirements.

Prerequisites

Since the SAP Web Dispatcher connects itself to the SAP message server and communicates with it via HTTP, the following parameters must be set correctly in the SAP Web Dispatcher profile.

●      rdisp/mshost: Host name of the machine on which the message server is running

●      ms/http_port: The port on which the message server receives HTTP requests

For the message server, this port must be configured as an HTTP port, by setting parameter ms/server_port_<xx> in the message server profile (see Message Server Parameters).

With a Java-only installation of the NetWeaver AS, the message server of central services (see Message Service) supplies the information. If ABAP is installed, all the information comes from the message server of the AS ABAP. The SAP Web Dispatcher knows from the above parameters which message server is used.

With an ABAP+Java system you have to specify the host and port of the message server for ABAP, because in this case only this has the full server information.

Features

The Parameter Overview describes the parameters used to configure the SAP Web Dispatcher.

The parameters used for both the Web Dispatcher and for the ICM are described in Profile Parameters for the ICM and SAP Web Dispatcher.

Many of the parameters are relevant for working with the SAP Web Dispatcher and its tables. Information about the tables can be found in Architecture of the SAP Web Dispatcher.

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