SAP Web Dispatcher: installation and applying patches

Symptom

• You want to install a current version of SAP Web Dispatcher, and you want to know which version to use and where you can find it.

• You are looking for the online documentation of SAP Web Dispatcher.

Other terms
sapwebdisp, wdispmon, wdispadmin.SAR, icmon, icmadmin.SAR

Reason and Prerequisites
To install the current SAP Web Dispatcher version, you must replace the required files and then restart SAP Web Dispatcher.

Solution

• Released releases of SAP Web Dispatcher for different SAP NetWeaver application server releases

 

Release of	Release of
SAP system	SAP Web Dispatcher
6.20	7.00 – 7.20
6.40	7.00 – 7.20
7.00	7.00 – 7.20
7.01	7.01 – 7.20
7.02	7.20
7.10	7.10 – 7.20
7.11	7.11 – 7.20
7.20	7.20
7.30	7.20
7.31	7.20
7.40	7.40

We currently do not support any other combinations.

If the 7. 40 SAP Web Dispatcher is operated by multiple systems, you can connect the backends of older releases in addition to the 7.40 backend.

• Installing a current SAP Web Dispatcher version

We recommend that you import the latest version of SAP Web Dispatcher after installation.
The SAP Web Dispatcher is provided on the SAP Support Portal at service.sap.com -> SAP Support Portal -> Software Downloads
-> Support Packages and Patches
-> Browse our Download Catalog
-> SAP Technology Components
-> SAP Web Dispatcher
-> < Release >
-> <Operating system platform>
The SAP Web Dispatcher versions that are provided on the SAP Support Portal are ASCII versions. You must also use these if the SAP system is a Unicode system.
If you have installed the SAP Web Dispatcher with the SAP installation as a separate system (with a separate SID), copy the files from sapwebdisp_< PL >-<…>.SAR into the directory
(such as D:\usr\sap\<SID>\SYS\exe\nuc\NTAMD64).
If you use the SAP Web Dispatcher in an existing SAP Web AS system (with the same SID), copy the files from sapwebdisp_< PL >-<…>.SAR into a separate run directory.

For this, you could, for example, use the following directories:
Windows: C:\Program Files\SAP\SAPWebDisp
UNIX: /usr/sap/<SID>/sapwebdisp

• Online documentation for the SAP Web Dispatcher

The documentation for SAP Web Dispatcher Release 7. 20 is available in the SAP Library or on the Internet (SAP Help Portal) at http://help.sap.com if you use the following path:
SAP NetWeaver -> SAP NetWeaver Platform -> Application Help – Function-Oriented View -> Application Server -> Application Server Infrastructure -> SAP Web Dispatcher
Instead of this path, you can also use the specified URL:http://help.sap.com/saphelp_nw73ehp1/helpdata/en/ed/2429371ec14c23a7508affa1280d07/frameset.htm (English)

The SAP Web Dispatcher documentation is identical for NetWeaver 7.0. Therefore, you can follow the described path even if you use SAP NetWeaver Release 7.0x (= NetWeaver 2004s).

 

• Further information

• Note that the names of the following two files for the SAP Web Dispatcher have changed in Release 7.00:
  For monitoring, the command wdispmon is used (instead of icmon).
  The files for the Web administration interface are available in the archive wdispadmin.SAR (instead of icmadmin.SAR).
