Patching Web Dispatcher?

Hi,
Web dispatcher download/installation (importing?) info at
http://help.sap.com/saphelp_nw2004s/helpdata/en/7c/6bf41aca84425196bd358df965fe3e/frameset.htm
is misleading, it lists SAPWEBDISP_<PL>.SAR as the latest Web dispatcher version, and mentions that DW_<PL>.SAR naming was used for older versions.
On the https://service.sap.com/patches sapwebdisp_0-20000961.SAR (patch level = 73) is older than dw_88-20000961.SAR (patch level = 87, not 88).
In order to patch older version of Web Dispatcher do I need to uninstall older version, and if so does uninstalling means deleting Web dispatcher directory?
Thanks!
Rob

Yes it was,

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

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.

Problem with Web Dispatcher with Double Stack

We have the latest version of Web Dispatcher - 7.0 with latest patch.
I'm having a problem where I am trying to use the web dispatcher for load balancing in a double stack (ABAP/JAVA) system. The person who did the install pointed the installation to the wrong server (which I assume can be easily changed in the profile). However, on the page where it indicates to activate the SICF services he left the box unchecked (but I checked that necessary ones were activated per note 552286). I now get these kind of errors when pointing to the http message server on a different system (he installed it assuming it was just for portal (java):
[Thr 5] *** ERROR => ICP_StructValue: illegal struct reference: wdisp_host_info.capacityIsFi
xed [icpvalue_mt. 257]
[Thr 5] *** ERROR => caught ICP exception (eval): ICP_StructValue: illegal struct reference:
wdisp_host_info.capacityIsFixed [icpvalue_mt.cpp 257] [http_adm_mt. 1488]
I get the above error when I go to "monitor server" groups in the web dispatcher admin console.
Here is my profile:
SAPSYSTEMNAME = PW4
SAPSYSTEM = 01
INSTANCE_NAME = W01
DIR_CT_RUN = $(DIR_EXE_ROOT)/run
DIR_EXECUTABLE = $(DIR_CT_RUN)

SAP Web Dispatcher Ports

Any insight is greatly appreciated!!

Hi,
I've never seen this error but some thing seems strange to me :
You use the same port (8101) for the listening port of the web dispatcher and the listening port of the message server of you back office system.
Is it really the case ?
Is PW4 the SID of you web disptcher ?
Is SAPSYSTEM = 01 the sysnr of your web dispatcher ?
I hope that the info of the web disptcher is not mixed up with the back office info ?
Regards,
Olivier

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

Hello Daniel,
We saw this error recently and have a fix available in the SR3 SAP note.
Please go to Note 1134777 - SAP NetWeaver 7.0 SR3 Installation: IBM DB2 for i5/OS and download the attached control.xml zip file. Make sure the name is control.xml and that it has todays date.
This file will have the DVD structure. You can patch your installation DVDs with it, but for your installation in progress just do the following:
1. Stop SAPinst
2. Download and extract the control.xml file from the attached file.
3. Find the installation directory of your current installation and replace the control.xml you will find there.
4. Restart SAPinst and choose to continue the installation in progress.
This file should be used for other standalone installations as well.
Best regards,
Luis

Web Dispatcher - Reverse Proxy and Load Balancing

I'm finding limited docs on Web Dispatcher with regard to reverse proxy and load balancing. Are you aware of some recent presentations or docs in this area? The info on help.sap.com is not what I'm looking for.
Thanks.

Hi,
best thing is that you look at your scenarios and test the web dispatcher against each of it, like:
- SSL
- Portal only
- Web Dynpro ABAP / Java
- BSP
- Different backend systems like SRM, MDM
- Several backends with 1 Web Dispatcher
After getting a list of use cases that you can test quite easily (installation of Web Dispatcher is done fast and can be done on a local PC), you can contact SAP Support and ask them about the specific problems and questions you encountered. This way, you'll get the official answer, sometimes they will even inform you about "secret" parameters and options.
As of the reverse proxy functionality: there are several version of Web Dispatcher available that differ from the functionality offered. The latest version - 7.2 - is the one that offers the most, i.e. allows you to create rewrite rules like Apache.

CRM_UI Reporting - HTTPS Terminating at Web Dispatcher or SSL all the way

Hi,
We need to set up access to crm_ui reports (leads and marketing mainly) in CRM 7.0 for vendors coming from the internet. The CRM server is in the internal network. In order for this to work I plan to setup the web-dispatcher in the application dmz. The initial login is going to be via the web dmz layer (using sun's iplanet server), which then routes the crm URL to the web dispatcher in the App dmz and then from the web dispatcher to CRM server.
One requirement from our security team is to set up the flow as HTTPS.
On going through SAP help I get the impression that it can be set up two ways, one, configuring web dispatcher to pass the SSL connection to backend, & two - configuring the web dispatcher to terminate SSL.
Seems the former is quite straight forward (from SAP online help we have to set the icm/server_port_<xx>> = PROT=ROUTER) but does it also require that we setup the crm_ui_frame service as SSL and activate the HTTPS service in ICM?
Or is it better to go via the second option (HTTPS termination) without changing the backend setup? SAP Online help lists steps to do the HTTPS termination but I have not come across any detailed documentation for the first method.
Any thoughts, suggestions will be helpful for either scenario.
Thanks,
Rommel Bhan

Thanks Martin the document helped.
Now the web dispatcher seems to talk to the HTTPS port on the backend.
However there is one issue I see in the dev_webdisp and was wondering if you have an insight.
Based on webdispatcher parameters, its taling to ms_https_port 8533 of backend

Portal and web dispatcher

Please i need your help, i´am new in this and i´am trying to run the portal on internet with the web dispatcher, i already get the wd work, and i can see the admin page.
I have de wd running on a web server (saphost1) in standalone mode,(when i configured the wd i gave the portal message server port, and the name of the host in which the portal is running), and the portal running in other server (saphost2) in an ABAP+JAVA WebAS,
i want to access the portal through the wd but i don´t know how to do that (redirect the url from saphost1:/irj/portal) , i searched in the docs but i haven´t found something.
Please help me i really need to get this done the sooner as possible
Thanks

How to use Web Dispatcher in XI

XI receives some messages and passes them onto CRM for processing. The user ID that is used between XI & CRM communication of Service user type.Due to this reason, this user has consumed the dialog processes available during the process.The error seems to indicate that the load was too heavy and that the system ran out of memory blocks reserved for XI to CRM communication. There are 2 application servers for CRM, in addition to the central instance.We can use the web-dispatcher in XI (instead of a particular Application instance).
Web dispatcher will then assign the message to the available application instance.
The question is How do we Use Web Dispatcher in XI with respect to this scenario??
Can anybody put light on this issue.

Have a look here

Web Dispatcher Not forwading XML document to SAP XI

Hi Everyone,
We have a web dispatcher that is accepting an HTTP Post over SSL and forwarding this connection to our SAP XI system. Our client post to the box and we see the ssl information in the log and then a string of information about connecting to our J2EE Engine where XI resides.
Here is a snippet from the SWD log:

Hi
Did you check the connectivity i.e web dispatcher with any other system(LandScape).
For example CRM for FICO.
Thanks

WebAS access via Portal: Web Dispatcher required for load balancing ABAP

Hi Folks -
We have EP 6.0 SP18 (Java only, WebAS 6.40, Unix/Solaris). The portal has a CI/SCS and one DI so we have a Web Dispatcher to load balance the portal servers. This works fine (and provides port 80 access).
This portal will provide access to HTTP services from an ABAP WebAS (6.20 with 6.40 kernel, Unix/Solaris). A landscape configuration entry has been added to the portal for this ABAP system. The ABAP system has a CI and multiple app servers, all capable of handling HTTP requests. This will also require port 80 access.
1. Will we need an additional Web Dispatcher to load balance HTTP requests to the 'backend' ABAP WebAS system, or will the portal be smart enough to handle the load balancing itself (perhaps based on the information in the landscape configuration)?
2. If the portal itself handles the HTTP load balancing can you point me to documentation (so I can make sure I have proper configuration)?
3. Are there any changes to this with NW2004s Portal (we plan to upgrade soon)?
Thanks in advance! Jeff

Jeff,
Regarding:
Q1. If you create a system object from the "SAP system with load balancing" template in portal and configure the object to point to your CI (msg server), the LB should be handled.
Q2. Portal load balancing is handled by the message server. If you point a test URL to the port of your message server, you will notice that you are issued a redirect the URL of your dialog instance. The web dispatcher is just a proxy (with some intelligence). When a request is made to the WD, it makes a connection to the MSG server, the list of active instances is queried, a redirect is made to that instanct. If you use WD, that connection can be proxied behind a standard URL. If you connect directly to the MSG Server instead, you will notice your URL change, just as it does on the service marketplace.
WDs are good for providing services, masked (proxied) behind virtual names. If you do not want the customer to see a physical URL of the server, use the WD. There are lots of other solutions that can do this too though such as Apache, ISA, Juniper devices, Cisco LDs. WDs have a very low performance threshold though, especially if you use SSL. WD is a performance bottleneck and should be benchmarked to see if it is right for your application.
Q3. No changes this architecture in 04s.
