configuration of SAP WEB DISPATCHER

Former Member

Hi everybody.

Sorry for my english in advance.

I'm trying to configure the WEB DISPATCHER to use as intermediary server in the dmz, to redirect the requests from the external to the intranet system.

I'm following the official guide of sap webdispatcher, i listened the live e-learning session, but nothing; i'm still not able to configure it.

Does anyone know how to find more information about it, or has any suggest to configure it?

Thanks!

Lorenzo

1. Copy the sapwebdisp.exe and icmadmin.SAR files to a

directory on what is to be the Web Dispatcher host.

2. Use sapcar –xvf to extract the icmadmin.SAR file into that

directory. The Web Dispatcher admin environment is extracted

to the admin directory there.

3. Execute sapwebdisp –bootstrap to generate an initial profile

for the Web Dispatcher

4. Start the web dispatcher with sapwebdisp pf=sapwebdisp.pfl

Hope this helps

Abdul,

Is this process documented anywhere?

Hi Abdul,

Three questions.

1) Do we need an SAP instance/ Web AS running on the host machine?

2) Is this OS independent?

3) Can we use Web dispatcher also as a proxy? (Both as Proxy and reverse Proxy)

Thanks

1. No you can run it standalone

2. I believe it is os independent.

3. I am not sure if you can use it as a proxy

Thank you very much Abdul!

We have the XI 3.0 license and we are looking for a link where we could download the web dispathcer.

Do you know where to download the web dispatcher? I assume it is free to download once we have the license for any of the netweaver components.

Thanks

Hi Suresh,

You could find more info about web dispatcher on this link:

http://help.sap.com/saphelp_nw04/helpdata/en/b4/9aa8862e714e6db8e74e48e5d3283b/frameset.htm .

If you do not have the executable sapwebdisp on your kernel CD or you want to use the latest version, fetch the current SAP Web dispatcher from the SAP Service Marketplace under http://service.sap.com/patches under SAP NETWEAVER ® SAP NETWEAVER 04 ® Binary Patches ® SAP KERNEL (32/64Bit, unicode/non-unicode) ® ® Database Independent. Here you can download the kernel packet DW.SAR, this contains the SAP Web dispatcher (sapwebdisp).

Hi,

I'm using SAP WEB DISPATCHER to receive a https request from our client/customer , validating with client SSL certificate and de encrypt this request to back end SAP WEB servers.

So I set up parameters in SAP WEB DISPATCHER for terminating the incoming https request and processing its own security environment. In this case which parameter should i use to assign ssl client/customer certificate for authenticating.

Thanks,

Bharath

hello,

I am having difficulty with the SAP webdispatcher installation on a DMZ server. I think my confusion is the DMZ server we have does not have any SAP executables except the 3 recommended from the SAP web dispatcher documentation. So on the DMZ server I have the sapwebdisp, icman, icmbnd and the icmadmin.SAR file...

I can not issue the sapwebdisp -bootstrap option on this server because I get an error

ahqecb1@a328706$ ./sapwebdisp -bootstrap

/usr/lib/pa20_64/dld.sl: Unable to find library 'libsapu16_mt.sl'.

There are no libraries on this server. How do I tell the sapwebdisp process to go to my server inside the internal firewall to get the libraries?

To put server names in play with ports how do you suggest we setup the sap web dispatcher. So the server in the dmz is dmz1 it will allow https communication over the port 443 and the server inside the firewall is appl1 with port 8070 configured for http communication.

Thanks is advance for helping us on understanding how the sap web dispatcher is working.

Please download and extract Unicode libraries from service.sap.com (they reside at the same location that SAP Web Dispatcher is). This libraries should be named like UCLIB ... If you already have them installed, check if they are accessible thru $path variable.

Despite talks about HTTPS advantage, I would use https only whether it is absolutely neccessary (such as credit card authorization pages os so). HTTPS+Web Dispatcher

can significantly reduce the performance for your sites (in comparison to a regular HTTP). Anyway, security and network landscape setup should follow your company policy as well as an amount and valuability of the data you plan to provide for outside access.

Thanks for the info but I am still having the error about missing the libsapu16_mt.sl. I did download the UCLIB*.SAR file and uncarred the file. it did not have the libsapu16_mt.sl. it did include the libsapu16.sl.

I have put in an oSS note to see if they can assist with the issue. I will let you know what we find out.

Hello Deidre,

I solved this problem with at symbolic link:

ln -s libsapu16.so libsapu16_mt.so
