SAP Netweaver Portal

This how to guide describes configuring SAP Web Dispatcher as a reverse proxy for the SAP Enterprise Portal so that you can easily publish the SAP Portal over the Internet.

Step: 1

Copy the following 2 files to a directory on the host where you want to configure the Web dispatcher:

• sapwebdisp.exe
• icmadmin.SAR

from the following location of the Portal Server:

:\usr\sap\\ JC\exe

The Uncar the file icmadmin.SAR, using SAPCAR tool.

Step: 2

In the Command prompt go to the directory where you have copied the above 2 files and enter,

sapwebdisp –bootstrap

This will generate the profile file (sapwebdisp.pfl) for the first time usage.









Step: 3


After the PFL file is generated successfully as shown above, the URL to call:

http://HOST-FOR-WEBDISP:PORT/sap/wdisp/admin/default.html







User: icmadm
Password: XXXXXXX

The user name and password is generated during the configuration of the Webdispatcher for the first time.











Step: 4

You can access your portal now via following URL:

http://HOST-FOR-WEBDISP:PORT/irj

Step: 5

If you need to run your Webdispatcher again then use the following command from command prompt.

sapwebdisp pf=sapwebdisp.pfl




Check the process running in the Task manager:













Step: 6
You can also install the webdispatcher to run as a NT service. You need to first download ntscmgr.exe from Service Market Place and then use the following command to install the web dispatcher.
NOTE:
Check for the ntscmgr.exe file in the folder \usr\sap\\JC\exe\ folder before trying to download from the Service Market Place.

ntscmgr install SAPWebdispatcher -b :\usr\sap\\ JC\exe\sapwebdisp.exe -p service pf=sapwebdisp.pfl
Step: 7
If the above command somehow didn't work properly, to fix this you need to do the following:




1. Edit the registry entry by running the program regedit.
2. Do a search for “SAPWebdispatcher” and change the ImagePath to where your sapwebdisp.exe is currently residing.

:\usr\sap\\ JC\exe\sapwebdisp.exe service pf=sapwebdisp.pfl















Step: 8
The URL redirect:
If you want to access the portal using the URL http:// HOST-FOR-WEBDISP and you are using SAP Webdispatcher, then you need to redirect the above URL to http:// HOST-FOR-WEBDISP /irj/index.html. This can be achieved by editing the sapwebdisp.pfl file and adding the following parameter,
# SAP Web Dispatcher Web Administration
icm/HTTP/redirect_0 = PREFIX=/, TO=/irj/index.html
After doing this, restart the SAP Webdispatcher.
