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

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 use the parameters to adapt the configuration to specific system requirements.
Tip The indexes of ICM and SAP Web Dispatcher vector parameters do not have to be assigned sequentially, they can normally contain gaps. Exceptions are the two profile parameters icm/HTTP/server_cache and is/HTTP/virt_host. See the metadata of the respective profile parameter.
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

If you have configured the Web Dispatcher for multiple systems, use parameter wdisp/system_<xx>. This parameter overrides the values of parameters rdisp/mshost and ms/http_port.

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.

Note

With Java-only installations of the SAP NetWeaver AS the message server of the Central Services supplies the information. With ABAP installations the information comes from the message server of AS ABAP. The SAP Web Dispatcher knows from the above parameters which message server is used.

Caution

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

"SAP Web Dispatcher Parameters - Reference" describes the profile parameters used to configure the SAP Web Dispatcher.

Note

Many of the parameters are relevant for working with the SAP Web Dispatcher and its tables.

Caution

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