SAP Web dispatcher and WebAS 6.20 ?

Hi all,
I'm trying to configure a standalone SAP Web dispatcher (SWD) to access our WebAS (WAS), but I don't understand how to setup the configurations files.
Currently I can reach the SWD admin via: http://swdhost:81/sap/wdisp/admin/default.html
The WebAS (ABAP) service I want to access is at:
http://washost/ris
The SWD pfl file looks like this:
# Profile generated by sapwebdisp bootstrap
# unique instance number
SAPSYSTEM = 1
# Accesssability of Message Servers
rdisp/mshost = swdhost
ms/http_port = 80
# SAP Web Dispatcher Parameter
wdisp/auto_refresh = 120
wdisp/max_servers = 100
wdisp/url_map_location = file://urlprefix.txt
# SAP Web Dispatcher Ports
icm/server_port_0 = PROT=HTTP,PORT=81
# SAP Web Dispatcher Web Administration
icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=./admin
Urlprefix.txt looks like this:
version 1.0
PREFIX=%2fRIS%2f&CASE=&VHOST=%2a%3a%2a%3b
Now after reading most of the post in the forum and the docs, I still cant understand how I can "say" to SWD to map http://swdhost:81/ris to http://washost/ris .
Thanks in advance for your help.
Best Regards
Erik

Hi Alexander,
Thanks, the ms/http_port parameter was not set in my WAShost, now the SWD can see the WAS
now if I try to reach :
http://WAShost:81/sap/public/ping , I get a reply from my WAShost.
but I can't reach http://SWDhost:81/ris or http://SWDhost:81/sap/bc/was/sap/zris
http://WAShost/ris is an alias of http://WAShost/sap/bc/was/sap/zris.
Anyway thanks already.
Cheers
Erik

Web Dispatcher and SNC WAS

If I connect my Web Dispatcher to a WAS that is not running SNC it connects okay but if I point it to a WAS that is running SNC I get SNC related arrors in the file dev_webdisp.log:
[Thr 6968] *** ERROR => invalid service descriptor token 'p:GB\SAPServiceQAS' [ictxxroute_r 2681]

[Thr 6968] *** ERROR => IcrUpdateServerPoolFromDescrString() failed 6 [icrxx.c      1762]
If I call the /sap/public/ping service on the WAS directly from Internet Explorer on my PC it connects okay, but if I call the same service from my PC via the Web Dispatcher it failes with the above message in the log file and the below HTTP message:
500 Dispatching Error

I cannot find any information relating to the Web Dispatcher and SNC on help.sap.com or OSS.
Do I have to install the SNC library onto the Web Dispatcher server? If so, how do I then reference it?
Any ideas?
Thanks.
Paul

Hi Paul,
SNC library is not required for Web Dispatcher.
The problem seems to be the data the message server provides with the URL http://<msg_host>:<msg_http_port>/msgserver/text/logon?version=1.2
If SNC is activated you will have an entry for RFCS in the data like:
RFCS     bin.wdf.sap.corp     4853     p/secude:CN=BIN, O=SAP-AG, C=DE
The error " invalid service descriptor token 'p:GB\SAPServiceQAS' " indicates that the parser could not parse the response from the message server. Then the server list is empty and you get the "dispatching error".
Maybe the backslash lets the parser struggle. Please check that you have an up to date version running (6.40 kernel patch level > 90). If that is the case, then this problem should be handled by OSS message.
Kind regards,
   Oliver

Diff. between Web Dispatcher and ICM

hi gurus,
Please help to understand the Difference between Web Dispatcher and ICM in whereas ways like
When do we use which tool?
The architec differences between them?
Anything more that would help me to understand better!
Thanks a lot in advance

Hi
At top level, Web dispatcher is like simple dispatcher which handles all the internet related requests like Http, Https, Smtp.
ICM is Internet connection Manager which is used to administer the flow between SAP and outside world using HTTP, HTTPs, SMTP

What is difference between Web Console and Web SAPConsole

Hello,
What is the difference between Web Console and Web SAPConsole.
Thanks,
Milind M.

Hello Milind,
I am not sure that there is any difference between Web console and Web SAP Console.
But of course, there is a lot difference between SAP Console and SAP Webconsole.
Using SAP console you can use mobile data entery with Character support where as with the help of SAP webconsole you can use web supported mobile data entry in which you can use touch screen device.
Hope this helps.

Diference Between Web Intelligence and Web Intelligence Rich Client?

Hey Guys,
Do you know the difference between Web Intelligence and Web Intelligence Rich Client?
I was asked about that but i couldnt help. And i need to make a decision about a Web Intelligence training. I need to decide using one or another.
Thanks
Vegas

Hi Vegas,
The Webintelligence Rich Client (WRC) has all the features of the thin webintelligence client. But WRC makes use of the client processor and memory to do all post query processing while Infoview Webi sends every request to the server for processing.
Thus you won't find any difference between the time taken to retrieve data from the database between these two clients. But there would be huge difference in performance while doing further analysis, formatting with the data. Also you will not need connectivity to the network to do analysis and formatting using the WRC client.
WRC client will help you to just retrieve the data on the fly and let you play around with it while you are traveling with no network connectivity.
Thanks

How to make the web part and web part zone smaller?

Hello Community
    On WS2012 running SharePoint 2013 Server when you edit a page
the web part zone is big and when you add the web part the web part
is big also.
    So the question is how to you make web parts and web part zone
smaller?
    Thank you
    Shabeaut

Hi,
According to your description, my understanding is that you want to make the web part zone and web part smaller.
When you edit a page, you could change the height and width of the web part in Edit Web Part -> Appearance by typing in the Height and Width field. The size of the web part zone changes with the web part.

Web dispatcher and J2EE load balancing

I have portal DBCI on one server and DI on multiple servers. I implemented Web dispatcher in front of the DI and it does the load balancing across all DI and CI. What I want to do though is not to route any users to CI instance - ie take CI server processes out of load balancing.
In ABAP environment you could create a logon group and not put CI in the group and users coming through the logon group do not go to the CI. I would like to do the same with Portal Java processes. In help.sap.com I found that web dispatcher uses default !J2EE group if there are no groups defined - to distribute users but I can not find anyway to define a logon group for J2EE java.
Does anybody out there know how to do this - define a logon group and include only DI and not CI in that?

We are using NW 04 based EP 6 SP 16. I am looking for to use web dispatcher to distribute users on the DI servers and not distribute any users on the CI server. What can I do so that if admin user enter http://CI_server:50000/irj then they can login to the CI server if users come through webdispatcher then they are not put on the CI but go to one of the DI servers only. By default web dispatcher would send some users to CI and I don't want that.

Web Dispatcher and SSL on ABAP+Java

Hello,
Have installed SAP web dispatcher on WAS 6.40 ABAP+Java system. Communicating with Portal SP16 system.
The HTTP works fine. Have not been able to get SSL working with web dispatcher.
For troubleshooting activated ITS on this system and HTTPS works fine with ITS webgui.
Have followed the "how to" SSL for web dispatcher guide.
Also should mention that we have generated certificate requests and PSE's but our organization has not yet chosen a certificate authority to sign the cerficates. For other scenarios (log onto Portal, XI, etc) the only difference is the certifcate warning dialog, otherwise works fine. Would this cause a problem for Web Dispatcher?
Trying the SSL end to end scenario receive
WARNING: Could not start service 0 for protocol HTTPS on host "max-sap" on all adapters
Is there anything
unique for the ABAP+Java configuration?
Thanks,
Alan

I solved this problem by setting the following profile parameter on my webdispatcher profile.
wdisp/ssl_ignore_host_mismatch = true
Doesn't fix the underlying problem but got me going until I can figure it out.

Web Dispatcher and SSL

Dear All,
I've configured Web Dispatcher with SSL. When I run command "sapwebdisp pf=sapwebdisp.pfl", my HTTPS service could not be started. It gives me error "WARNING: Could not start service 60000 for protocol HTTPS on host "myserver" (on all adapters)".
Any idea?
BTW, my SAP Web Dispatcher is up and running.

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

Transport Webi Reports and Web services as the backend of dashboards from BO Production to BO Development system

Hello Experts,
I am working on SAP BO 4.1. I have made several dashboards on top of web services ie;Web Service Method. I have 2 systems in BO ie; Development and Production Systems.The BW production system is connected to BO Development and Production both.
The Webi reports are made on top of BI BEx Query. From the webi reports, BI Web Services are made on top of which the dashboards are made further.
The Webi Reports, Web Services and the Dashboards everything is made directly in BO Production.
My question is, Can I transport the Webi Reports and the Web Services from BO Production to BO Development?
And If yes, will it have any other impact on webi reports, web services or dashboards?
Thanks & Regards,
Alfred Thomas

Hi Gill,
As per your reply,with the promotion managament i have make the web services again manually in Dev system...Right?
Is there any way possible that i can transport the webservices and the webi reports usind Query AS A Web Service Designer. And if yes, through this QAAWS will the WSDL or the URL required for the web services in the connection button in dashboards will automatically updated or changed as per the Development System?
But i am not able to enable the "Deploy to Other servers Option" in QAAWS.
Can you please help?
Regards,
Alfred thomas

Web Dynpro and Web Service Error

Hi experts,
I followed the blog u201CDeveloping Web Services in J2EEu201D /people/lakshmi.prasad5/blog/2009/06/30/developing-web-services-in-j2ee-and-consuming-in-sap-netweaver-visual-composer-part1 and is very well explained and easy to follow. The author does two Methods and the final Web Service concatenates input fields. One Method concatenates two words and the second Method concatenates three words, the final result is the concatenation of the words in both cases. The Web Services is working fine I already tested and do it in a Visual Composer Project. Now, I want to Execute the Web Service in a Web Dynpro for Java WD4J Project. I did my application, my model (ConcatinationWSModel) and my View. I mapped the class that concatenates two words and is call u201CRequest_ConcatinationOfStringu201D. The problem comes with the Execution of the Web Service and is showing me the next exception:
u201Ccom.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service with WSDL URL 'http://<host>:<port>/WebServiceconCat/Config1?wsdl ' with operation 'concatinationOfStrings' in interface 'WebServiceconCatVi_Document'u201D

          ConcatinationOfStrings input2 = new ConcatinationOfStrings(model);

          input2.setFString("SAP");
          input2.setSString("UK");
          ConcatinationOfStringsResponse input3 = new ConcatinationOfStringsResponse(model);

          wdComponentAPI.getMessageManager().reportException("The error is: " + ex,true);
    //@@end
I believe that the error is in the way I am executing the Web Service but I am not sure. Any help will be appreciated.

David Corté

Hi Jesus,
Your answer was very helpful..... The problem was with my code. The way I was executing my web service was wrong..... There are two things we have to keep in mind while we invoke any web service.... The doinit method and the execution sentence.....
public void wdDoInit()
    //@@begin wdDoInit()
     model = new ModelWebServcie();
     Request_ConcatinationOfStrings input = new Request_ConcatinationOfStrings(model);
     ConcatinationOfStrings input2 = new ConcatinationOfStrings(model);
     input.setConcatinationOfStrings(input2);
     wdContext.nodeRequest_ConcatinationOfStrings().bind(input);
    //@@end
and the exection method:
public void ExecuteWebService( )
    //@@begin ExecuteWebService()
     try {
                    wdContext.currentRequest_ConcatinationOfStringsElement().modelObject().execute();
                    wdContext.nodeResponse().invalidate();
               catch (Exception ex)
                         // TODO: handle exception
                         //        If an exception is thrown, then the stack trace will be printed
               wdComponentAPI.getMessageManager().reportException("El error en ExecuteWS es: " + ex,true);
               wdComponentAPI.getMessageManager().reportSuccess("El Web Service fue ejecutado con exito");
    //@@end

Not able to see the accessories in IC Web Client and Web shop

Hi All,
we have configured Method Schema for Product accessories and maintain the accessories in product master.
I am facing an issue where in i cant see the accessories in IC Web Client and webshop.
Any input will be a great help.
Thanks in advance.
DV.

I'm answering this only because I just ran into this yesterday.
Apparently, the Accessories you add to the Product Master have to be added to the item in the Product Catalog.
In the Item view of the catalog, click on the Edit List of Accessories button. The accessories that you added to the Product Master show up on the right side of the window. Select the accessories you want to show on the Webshop (and I assume IC Web Client) and click the move (left arrow) button. Save, replicate, etc...
Now, if someone knows how to avoid this step, please share it, as I find it annoying that while I can get the accessories to the Product Master easy enough, I can't get them to the Webshop without an extra step FOR EACH ITEM in the catalog(s).

WLC: which software-version support SHA2 certificates for Web Authentification and Web Management ?

Hello,
I tried to install new SHA2 3th-Party certificates on our WLCs. There are old WiSM1-Boards and 2504 to support our old 1230 Access Points, running 7.0.251.2, which didn't install it, although the config manual for 7.6 and 8.0 say that SHA2 certificates are supported since 7.0.250.0. When I tried to install the SHA2-certificates I get the message "File transfer failed" an the log says:
*TransferTask: Dec 12 13:22:14.394: #UPDATE-3-CERT_INST_FAIL: updcode.c:1869 Failed to install Webauth certificate. rc = 1
*TransferTask: Dec 12 13:22:14.394: #SSHPM-3-KEYED_PEM_DECODE_FAILED: sshpmcert.c:4085 Cannot PEM decode private key
I tried to install the same certificates on our WiSM2-Boards, running 7.4.121.0 and I failed too. The same certificates could be installed on a 2504 running 8.0.100 without any problems.
In all 3 cases I tried to install unchained certificates for web management and Level 3 chained certificates for web authentication. I used the following guides to get the certificates (e.g. taken from the config manual 8.0.100):
http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/109597-csr-chained-certificates-wlc-00.html
http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/70584-csr-wlc-00.pdf
Which software versions support SHA2 certificates and which didn't ? Is the a list for it ?
Regards

Hello,
I solved the problem. First I used a Debian Linux system with Openssl 1.0.1. After I searched the internet using one of the log messages above I found sites which mentioned to use Openssl 0.9.x. So I tried a productive and security fixes Debian Linux System running Openssl 0.9.8 and I succeeded. The wlcs accepted the certificate files and used it after a reboot. The Web GUI still shows a SHA1 Fingerprint, but the certificate signature Algorithm is SHA2:
Signature Algorithm: sha256WithRSAEncryption
When you check the openssl.org homepage Openssl 0.9.8 is still one of the actual version of openssl and is still available and fixed. But the Openssl Roadmap says:
"We don't want to have to maintain too many branches. This is likely to include a timescale for the EOL of version 0.9.8"
I don't know the differences between certificates made with openssl 0.9.8 and 1.0.1. Is there anybody who can explain it to me ?
