Web Dispatcher on iSeries

Hi All,
I am trying to install a standalone NW2004s SR3 Web Dispatcher on one of our partitions, but when the install process gets to the Install Instance Basics stage I get the errors below:
ERROR 2008-06-03 11:46:17.73
FJS-00003 TypeError: nwdb_db4.getABAPLibASP is not a function (in script NW_Webdispatcher|ind|ind|ind|ind, line 59556: ???)

Has anybody seen this before? If so, is it possible to get round this?
Thanks,
Dan

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

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.

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.

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'

Web Dispatcher not doing the load balancing on the portal

Hi Experts
I am having a production issue where the SAP web dispatcher is not doing the load balancing on the portal.
We have ESS/MSS portal with 1 Message server and 2 Application servers. The Web dispatcher is installed on the message server itself. Here is my Web disp profile file

wdisp/HTTPS/sticky_mask = 255.255.255.255
In my Web dispatcher Admin page, I see all the three application servers, however the requests are going to only 1 App server. We are using ENd to End SSL configuration for the web dispatcher.
We also have a reverse proxy in the landscape and reverse proxy is forwarding all the requests to the Web dispatcher. In Web disp Admin page>Dispatching Module>SSL End to END dispatching, I see only ONE table entry in the dispatching table and it is our Reverse Proxy.
As all the requests are coming from only one source (Reverse proxy), it seems to me that the sap web dispatcher is forwarding those to the same Application server every time.
Can anyone please advise ?
I also tried to configure logon group in NWA, the web dispatcher is detecting the logon group and all the app servers in the logon group. It still not doing the load balancing.
I would greatly appreciate any help.
Thanks
Viny

Vincent, can you please elaborate more ? Is the web dispatcher not able to recognize stateful and stateless application requests ?
I saw that the procedure for configuring SSL Termination on Web dispatcher is long and complicated and looks like SAP web dispatcher needs to have SSL certificate of its own. As we have no ABAP servers and only Java servers, I can not even create the PSEs using STRUST (as described in SAP help -http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/99c388d7c46bb9e10000000a42189d/frameset.htm
We already have SSL certificates for Java App servers.
I suppose there should be a way for web dispatcher to identify the incoming requests and forward to appropriate application servers.
Any help is much appreciated.
Thanks
Viny

URL for SOAP sender in case of web dispatcher

Hello,
I have a scenario SOAP-->XI -->RFC synchronous.
The soap request coming to XI is HTTPS without client authentication.
The URL is:
https://sapxiq:50101/XISOAPAdapter/MessageServlet?channel=:Srv_Web:Srv_Web_Soap_Server&version=3.0&Sender.Service=Srv_Web&Interface=http%3A%2F%2Fabc.com%2Fxi%2FeBillViewer%5Eos_getDocumentRequest
We have installed web dispatcher for load balancing.
Do I need to change the URL to replace web dispatcher host and port?
What is the additional setting need to be done in the web dispatcher profile?
Do I need to add icm/server_port_1 = PROT=ROUTER,PORT=443 in profile?
Thanks in advance,
Beena.

Non-central adapter engine setup with web dispatcher

Our PI setup is working perfectly in our private zone, now the requirement is to expose our PI to public zone to do our B2B transactions. We have proposed a solution but I need your expert suggestion on this. Solution proposed
Public Zone -|Semi public zone| Semi private zone |----Private zone
|>>>Application gateway >>>>>>>>| Non-Central Advanced<==========>|------ PI 7.1
|>>>(For Inbound message) >>>>>>| Engine (For both Inbound and<=====>|------(IS, central AAE, IE)
|<<<<< Proxy<<<<<<<<<<<<<<<<<<|Outbound message and<==========>|
|<<<<<For outbound)<<<<<<<<<<<<|Load balancing for B2B)<=========>|
Non-central AAE will be in semi private DMZ. It will send/receive all B2B messages from/to semi public DMZ via Application gateway for inbound messages and proxy for outbound messages.
Then Non-central AAE will work with the PI central instance running in Private DMZ to receive and send messages.
My Questions:
1) Do we need a SAP web dispatcher to work in between (Application gateway, Proxy) and (Non-central AAE)   ?
    My understanding: SAP web dispatcher balances the load which will enhance the performance but it is not mandatory. Non-central AAE can work independently with Application gateway and Proxy to receive and send messages.
2) What is the configuration we need at non-central AAE to exchange messages with the application gateway and proxy?
Thanks
Amaresh

what is use of non central Adapter engine in Java server proxy?
The collaboration profile agreement service (CPA service) does not read the CPA cache from the Integration Directory.
You define the user that is to send the messages to the Integration Server in a service parameter. When the Integration Server receives the message with this user, it checks the user using the access control list. This check is not performed for the technical user XIAFUSER.

Hello Nani,
It looks to be a SNC Issue.
just check wether you have the parameter snc/gssapi_lib define in ur profile of SAP system
This parameter should be set to the path of your gssapi32.dll file
Also u must also have a system variable defined SNC_LIB which is again to the path of gssapi32.dll
Also make sure that gssapi32.dll exists
Check these,ur web dispatcher might come up
