Web Dispatcher Installation

Former Member

Hi Expert,

I am in a confusion regarding the Web Dispatcher installation. i have Used SAP Netweaver 740 SR2 for Web Dispatcher and Have installed on a server where SAProuter is Configured.

Here are my Question:

1. We have 3 System ( Ecc, Gateway and Solman) for which we have to install web-dispatcher. My question is Do i have to install 3 web dispatcher for the      3 servers or i can install one Web Dispatcher and link it with all 3 server. i have never worked on Web-dispatcher Before.

2. Also in SCN, i have came across some info on SAP Web Dispatcher for Multiple Systems (See Link Below), but couldn't figure out how to do it as while Installing the Web-dispatcher, it asked for message server host name where i had put Ms hostname of the Gateway Server. so if we can add all three system through 1 Dispatcher how will it be.

SAP Web Dispatcher for Multiple Systems - SAP Web Dispatcher - SAP Library

3. Also Do i have to Make Changes in Profile as Post Configuration setting for SAP Web dispatcher for Gateway system, And What could be the changes.

Thanks

Hi Xherdan,

SAP Webdispatcher 740 supports multiple system connection.

You need to maintain the below parameters in the instance profile of web disptacher

wdisp/system_0 = SID=ERP, MSHOST=ms_erp, MSPORT=8182, SRCSRV=webdisp1:80$$

wdisp/system_1 = SID=CE1, MSHOST=ms_ce1, MSPORT=8127, SRCSRV=webdisp1:5$$00

You need to define the ports 80$$ and 5$$00

icm/server_port_0 = PROT=HTTP, PORT=80$$

icm/server_port_1= PROT=HTTP, PORT=5$$00

You have to maintain the SRCSRV argument to call the URLs of respective systems.

SICF Service :

To call the SICF service with the help of SAP Webdispatcher , you need to maintain the HTTP message server PORT of ASCS service.

For Java System :

To call the urls of java system you need to maintain the SCS Message server HTTP port.

You will get the message server HTTP port information in dev_ms log file

Hi Ashutosh,

Thanks for the reply

i have come across these steps but my 2nd question is still in doubt..

Since during the installation, we have put the gateway message server for the Installation of Web Dispatcher then how other system will be added.

Still am not able to get any clarification on this anywhere on SCN.

Thanks

Hi Xherdan,

The parameter wdisp/system_0 will connect the Web Dispatcher to the respective system.

So you dont need to worry about the other parameter.

Kindly paste the parameter of which you are talking about.

Hi Ashutosh,

Thanks for the reply.

Please see the Screenshot

During the Installation, we had this step where it asked for message server host which i put the gateway message server host name.

So since i have put only gateway's MS name, how will it take the other systems.

Thanks

Hi Xherdan,

In the above screenshot , it will set the below parameters

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 dont want to use them , you can hashed out the parameters.

So since i have put only gateway's MS name, how will it take the other systems.

Other system will be connected by the web dispatcher with the help of the parameters

wdisp/system_0 = SID=ERP, MSHOST=ms_erp, MSPORT=8182, SRCSRV=webdisp1:80$$

SID = SID of the target system

MSHOST : message server host name of the target system

MSPORT : HTTP Message server port

SRCSRV : you to maintain the port of the target system , to access the HTTP request

Hello Xherdan,

The reason for that step in specific is that the feature where the same web dispatcher can forward requests to multiple systems is quite new. This way, even informing any message server at that step, as soon as you add parameters like "wdisp/system_X" at the profile, the parameters "mshost" and "msport" will be ignored.

Nevertheless is still good to comment them.
