Web Dispatcher Configuration.

Hi,
1)Our srm server is connected to portal and end-users are using portal to connect to it. Srm server has another 2 other application server for load balancing.
As Load balancing is not happening we are getting ITS memory bottle neck issue.
We have installed Webdispatcher for load balancing but I have confusion how will be connectivity Portal --> SAP Web Dispatcher --> SRM.
2) C:\usr\sap>sapwebdisp.exe -checkconfig pf=c:\usr\sap\sapwebdisp.pfl

Web Dispatcher configured but not working

Hi,
We wish to configure SAP Web Dispatcher as a reverse proxy. For this we've installed using sapinst SAP Web Dispatcher Version 7.00.11, multithreaded, ASCII, 64 BIT Patch Level 140 which was manally updated to SAP Web Dispatcher Version 7.10.1, multithreaded, ASCII, 64 BIT Patch Level 152.
The SAP Web Dispatcher server is in DMZ whereas the Enterprise Portal servers are in the intranet.
The updated SAP Web Dispatcher is available in /sapmnt/<SID>/exe and not in a seperate directory (/usr/sap/<SID>/sapwebdisp) as per SAP note 908097. The SAP Web Dispatcher has been installed on a standalone machine with instance number 00.
I've configured the Sap Web dispatcher with the -bootstrap option. The -checkconfig option completes with 0 warning 0 errors.
The TCP ports between SAP Web Dispatcher and Enterprise Portal servers are opened in the firewall. Also, required ports 22 & 8100 are opened from my computer to the SAP Web Dispatcher Server.
Yet when I try to connect to the administrator interface with the URL http://<Web_Disp_IP>:8100/sap/wdisp/admin/default.html, I receive the following text on the browser:
Network Error (tcp_error)
A communication error occurred: "Operation timed out"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
Similar message is received even if the SAP Web Dispatcher is installed in a seperate directory.
Has anyone come across a similar issue?
Thanks.
Regards.

Web Dispatcher configuration (ABAP+Java vs. ABAP+Portal)

We are using an internal Web Dispatcher to allow the connections from different networks.
This Webdispatcher entry we add to WAS configuration within Portal system object
By defintion of ABAP+Java double stack we do not have any problems and the test
http://webpispatcher:port/sap/bc/ping is successful.
When we have a ABAP system + Portal (Java) we only can test the connection
http://webpispatcher:port/
When we execute the test
http://webpispatcher:port/sap/bc/ping we get an error, because the url goes to Java stack.
We also detected that on Web Dispatcher configuration for ABAP+Java we have ABAP and J2EE server groups and application servers.
For ABAP+Portal we have only J2EE groups on Web Dispatcher configuration.
Question:
Which SAP parameter (e.g. ms/server_port_0, icm/HTTP/j2ee_0) or Web Dispatcher parameter (ms/http_port) is responsible for generation of ABAP groups (e.g. PUBLIC) within Web Dispatcher?

Which SAP parameter (e.g. ms/server_port_0, icm/HTTP/j2ee_0) or Web Dispatcher parameter (ms/http_port) is responsible for generation of ABAP groups (e.g. PUBLIC) within Web Dispatcher?
In ABAP the logon group is handled by the ICF. In SICF you specify within the actual services(properties) which logon group that service should use for load balancing. As far as I remember though there is an exception if you are using an "end-to-end" ssl configuration where you can specify the destination logon group using wdisp/HTTPS/dest_logon_group parameter.
rdisp/mshost is the parameter on your web dispatcher that points to your message server to get a list of available logon groups.

SAP Web Dispatcher Configuration in a FPN

Hi all,
We are using SAP Web Dispatcher 720 (latest patch 85).
We are having a FPN network. One consumer portal, with more than 5 producer portal (ECC JAVA, BW JAVA..etc) and more than 5 different backends (ECC, BW, SRM..etc)
We are using SSL termination at the web dispatcher.
We have configured all our consumer, producer, backends in our web dispatcher instance, to use the domain name with different ports.
Eg :
https://domainname.com - refers to our consumer portal
https://domainname.com:7110 - refers to our producer portal 1
https://domainname.com:7111 - refers to our producer portal 2
https://domainname.com:6100 - refers to our ABAP backend system 1
https://domainname.com:6111 - refers to our ABAP backend system 2 ..etc..,
by configuring so, we are facing lots of page not found issue intermittenly, as SAPlb cookies are passed incorrectly, since all refers to the same domain name (it ignores the different ports).
Can someone helps us to narrate how to configure web dispatcher which suites our FPN network. We can't go for different URLs for each system, as it requires more than 16 URLs and 16 web dispatcher instances.
Can someone share their experience
Thanks & Regards
Senthil

Hello Ravi,
Try to include directory 'admin' within directory
'sapwebdisp'.
You can let sapwebdisp create a sapwebdisp.pfl on your
behalf with option '-bootstrap'.
You will see the password for user 'icmadm'.
and this line
"icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=./admin"
Then you use URL
'http://sapwedisphost:<xxxx>/sap/wdisp/admin/default.html'
See this documentation in
'http://help.sap.com/saphelp_nw04/helpdata/en/b4/9aa8862e714e6db8e74e48e5d3283b/frameset.htm'

SAP Web Dispatcher Configuration (SSL, certificates)

Hi all,
We're trying to configure the SAP Web Dispatcher for the use of SSL (terminated) and client authentication using x.509 certificates. All works (almost)fine. However, there's some strange behavior that I can not explain.
The following access point have been specified in the profile:
Description of the Access Points
icm/server_port_0 = PROT=HTTPS, PORT=443, TIMEOUT=15
icm/server_port_2 = PROT=HTTP, PORT=83, TIMEOUT=15
icm/HTTPS/verify_client = 2
Basicly we only need users to access the web dispatcher using SSL. However, when I remove the line: icm/server_port_2 = PROT=HTTP, PORT=83, TIMEOUT=15
The Web Dispatcher returns an error upon accessing it using HTTPS:
Dispatching Error
Error: -26
Version: 6040
Component: HTTP_ROUTE
Date/Time: Tue Mar 14 07:19:38 2006
Module: http_route.c
Line: 2383
Server: sapvm1_DVS_26

Any help would be highly appreciated. Thanks!

Hi KS,
Maybe you were right afterall I found a nice How to on the servce.sap.com (https://websmp203.sap-ag.de/~form/sapnet?_SHORTKEY=00200797470000073632&_SCENARIO=01100035870000000202) and it seems you do have to add the HTTP server_port parameter in case SSL is being terminated (no re-encryption).
icm/server_port_0 = PROT=HTTPS, PORT=443, TIMEOUT=15
icm/server_port_1 = PROT=HTTP, PORT=0, TIMEOUT=15
However, the trick is to set the port to zero (0), that way you can still only access the Web Dispatcher via HTTPS.
All is working now.

Single Web Dispatcher for Multiple SAP Systems

Having read a number of posts & S-Notes, I found that Web Dispatcher 7.2 is capable of routing between multiple SAP instances.
But despite having troubleshooted, I am unable to make it work. I have two separate installations ERP & Portal on the same host, but my web dispatcher only routes to one of them at the same time. Simultaneous access to these 2 systems is not possible either with URL or Port control procedure mentioned at url http://help.sap.com/saphelp_nw72/helpdata/en/c5/ec466f5544409982c7d3ca29ce1ad3/frameset.htm
Can anyone point an error in my below mentioned configuration of web dispatcher file.
I want requests on port 8853 of my web-dispatcher to be routed to system DEV &
the requests on port 8843 of my web-dispatcher to be routed to system DEP
rdisp/mshost = sapdeverp
ms/http_port = 8100
icm/server_port_0 = PROT=HTTP,PORT=8853
icm/server_port_1 = PROT=HTTP,PORT=8843
wdisp/system_0 = SID=DEV, MSHOST=sapdeverp, MSPORT=8100, SRCSRV=*:8853
wdisp/system_1 = SID=DEP, MSHOST=sapdeverp, MSPORT=8102, SRCSRV=*:8843
Can we mention multiple message servers instead of single message server "rdisp/mshost = sapdeverp
ms/http_port = 8100" ?
Any suggestions ?

Very right in mentioning this point coz myself have been confused over it but if I remove these lines & execute the -checkconfig:
then it states as below:
Checking SAP Web Dispatcher Configuration

I have tried this actually, even tried the option ms/server_port_0 & 1 to replace ms/http_port but it didnt work either.
Any more ideas.. ?

Error SAP Web Dispatcher

Buenas tardes estimados,
Configure el web dispatcher con solman pero el webdispatcher solo me permite acceder a los servicios del stack de java que corren en el puerto 50000 pero no me deja ver los servicios abap de la SICF que corren en el puerto 8000 alguno tendra una idea de porque ocurre esto? y como puedo solucionarlo?

Hola Diego,
Te comento si estan corriendo perfectamente mis servicios de la sicf por el puerto 8000 y los de java por el 50000 mi ms/http_port es el 8101 lo que pasa es que el web dispatcher solo me detecta el stack de java no me detecta el stack de abap por ende puedo acceder a cualquier servicio que corra en el puerto 50000 pero a los que corren en el puerto 8000 que son los de abap no le llego por el webdisp porque el mismo no me esta detectando el stack de abap.
Pude observar que al introducir esta url http://ServidorDeSolman:8101/msgserver/text/logon obtengo este resultado:
version 1.0

Como podemos observar solo arroja info del stack de java y los puertos java pero no arroja la info del stack de ABAP.
Tambien por el webdisp realice esta prueba via linea de comandos en el cmd:

Web dispatcher/WAS getting SSL error

We have 2 SAP web dispatcher configured to have HTTPS protocol, with re-encryption in our BW and CRM system.
Both of them are configured identical. However, in the web dispatcher trace file I see that the CRM environment have auth_type =0 (no client cert) and the BW has auth_type = 3 (use client cert). I am not sure what sets this parameter, and how can I change the CRM to have auth_type=3.
In our CRM web dispatcher log we get the following message:

4- I have mapped this client certificate in table USREXTID
5- I have also installed the above client certificate in my browser.
Now, when I am accessing the Server thru HTTPS web link, I am getting this Windows:

How to Install & Configure Web Dispatcher

Hi techies,
How to install and configure SAP Webdisptacher in an existing BI System.
What are the parameters need to be set after installation like ports, memory , profile parameters etc., for webdispatcher.
I am new to this concept
Thx in advance.
Haroon Khavi.

Hi,
The webdisp does not need the SID of the system it is connecting to. The only parameter it needs is a "Unique Instance Number for SAP Web Dispatcher (SAPSYSTEM)".
You can check this with the following command:-
sapwebdisp -bootstrap
If you are installing the webdisp on a server that already has a SAP instance then you have to enter a unique number (not the SAP instance number). You can used any value from 0-99.
This parameter is used for shared memory allocation so should not be the same as the SAP instance or any other webdisp installed on the same server. Of course if there is only the webdisp on the server than any value from 0-99 can be used.
Hope this helps
Michael

Web Dispatcher medium / large configuration

When we install web dispatcher, we are given an option for creating configuration for system of size medium / large...
There is a system installed as medium and I am looking it to adjust for large number of users..
Any help on what parameters will I have to change ?
icm/max_conn =
icm/max_sockets =
icm/req_queue_len =
icm/min_threads =
icm/max_threads =
mpi/total_size_MB =
mpi/max_pipes =
Apart from these, is the any other setting (not only parameter) that should be changed.. memory related etc ?

Hi Jay,
Parameter Settings Dependent on System Size
Depending on which system size you have chosen (s, m or l), different parameter values are written to the profile file. The table below contains these different values.
Parameters                  Small (s)           medium         large
icm/max_conn          100                   500                   16384
icm/max_sockets      1024                 1024                16384
icm/req_queue_len    300                   500                 6000
icm/min_threads       5                       10                   100
icm/max_threads      15                      50                       250
mpi/total_size_MB   100                    500                2000

SSL Configuration between Web Dispatcher and Portal

Here is the scenario:
INTERNET -
https--> WEB DISPATCHER (decryipts)-https> PORTAL
When a request for portal page is sent to WEB DISPATCHER, it gives the following error in dev_webdisp:
[Thr 1087416640] ERROR in ssl3_get_server_certificate: (9/0x0009) the verification of the server's certificate chain failed
ERROR in af_verify_Certificates: (12851/0x3233) Verification of one certificate of path failed because the CA flag of its basic constraints is set to FALSE
ERROR in check_basicConstraints: (12851/0x3233) Verification of one certificate of path failed because the CA flag of its basic constraints is set to FALSE
I am using SAP's test certificates and there is no documentation for the error as far as I know.
Any ideas ?

Hi Cristiano,
I solved the problem.
This error message is being caused by the mismatch between the issuer (SAP Test) and server pse generation strings (for example O and OU values ).
As the documentation suggests:
"For example, if you use the SAP CA, the naming convention is CN=<host_name>, OU=I<installation_number>-<company_name>, OU=SAP Web AS, O=SAP Trust Community, C=DE."
Thanks for the reply,
Best Wishes
