SAP WebDispatcher - system requirements & general questions

[Former Member]

Hi all,

possibly we would like to use the SAP WebDispatcher as reverse proxy for

our SAP EP infrastructure. Our main goal is to secure accesses from the internet to the sap ep by installing the SAP WebDispatcher in a DMZ.

Could someone give me information about the hardware/system requirements

of the SAP WebDispatcher?

(supported operating systems, recommended CPU / Ram size, is a database necessary (if yes, which is supported))

Is it possible to restrict the requests to the SAP WebDispatcher from only

specific IPs or IP-Ranges?

Just for my curiosity: what's the implementation language of the SAP WebDispatcher.

Are there any important security vulnerabilities known?

Any help is really appreciated

Hello,

Did you make some research in help.sap.com and sapservice.sap.com and the find button on SDN ? Much of the answers for your questions are there waiting for you to read them !

Anyway,

The supported OS are the same as Netweaver (Linux, Unixes and Windows), both 32 and 64 bit.

The hardware requirements are low, but depends obviously of the number of http requests to process per second. For instance we use a Linux x86 biprocessor blade with 2 GB ram, for a moderate load and the cpu load is lower than 3 %...

There is no database for the sap web dispatcher. what would be its use ??

Yes it is possible to filter IPs or IP-ranges. Check icm/HTTP/auth_xx parameter and http://help.sap.com/saphelp_nw04s/helpdata/en/b4/9aa8862e714e6db8e74e48e5d3283b/frameset.htm.

For the implementation language, the release information for a web dispatcher 7.0 running on Windows 2003 tells me :

compiled on NT 5.0 2195 Service Pack 4 x86 MS VC++ 13.10

So I guess the language shoul be C++.

Hi Karin,

You can find SAP Web Dispatcher installation guide at

http://service.sap.com/instugides - SAP Netweaver - SAP Netweaver 7.0 (2004s) - Installation Standalone Engines

This installation guide also contains useful OSS notes, which should give you additional information.

Hope this meets your requirements.
