Webdispatcher for Load balancing

Hi All,
We have implemented EP7. The portal is configured to redirect to https.
Now we want to use sapwebdispatcher for load balancing.
We are performing the following steps to configure the sapwebdispatcher
1. uncar the icmadmin.SAR
2. sapwebdisp -bootstrap
The following screen appears:
This bootstrap will perform the following steps:
1. create profile file "sapwebdisp.pfl"for SAP Web Dispatcher (if not already existing)
2. create user for web based administration in file "icmauth.txt"(if not already exisiting)
3. start SAP Web Dispatcher with the created profile
After the bootstrap you can use the web based administration

SAP Web Dispatcher bootstrap ended (rc=0)
<hostname>47> *** WARNING: Could not start service 8101 for protocol HTTP on host "<hostname>m"(on all adapters)
SAP Web Dispatcher up and operational (pid: 14014) ***
Now, if I use any port other than 8101 for HTTP port number for SAP Web Dispatcher the webdispatcher does not work.
If i use port 8101(which i am using currently) then the webdispatcher does the load balancing however i cannot access the http://<hostname>:8101/sap/wdisp/admin/default.html url
Can anyone help me getting both thigs: load balancing and the webdisp admin page also.
Thanks!!

Rohit

SAP Webdispatcher Setup for J2EE 640

Dear Basis Guru's,
I am trying to setup SAP Webdispatcher for our customer system. J2EE Instance is installed in a hostname called javadev which is in a domain where all other SAP Instnaces are setup ( XYZ.COM). I have installed SAP Webdispatcher in a other host called webdispdev which is existing in different domain (XYZWEB.com) Firewall rules are updated and J2EE Engine ports are opened to connect to this host.
I have generated the SSL key pair and got it certified by Digicert CA and imported it back. Now i have to configure url re direct for this webdispatcher so tht users can access j2ee instnce using with webdispatcher hostname , I have tried adding the web service name provided by developer to the url_filter , I can access this webservice using with http port , I cant access it using with j2eeengine https port . I have addedd https port to the webdispatcher profile and it fails to start when i add https port.
When i compare the new setup with existing prod systems i can see https port is addedd to sapwebdisp.pfl and users able to access it successfully. Although sap webdisp installed in one host name which is in XYZWEB.COM and users are accessing it using with diff hostname which is in XYZ.COM (Ex: webdisp host - webdispprod.XYZWEB.COM and they are accessing it using with webdispprod.XYZ.COM) looks like ur reditect setup in DNS?? I was not invloved in prod webdisp setup and i dont have any info how it was configured.
Please help me to fix the below issues
1.when i add https port to sapwebdisp.pfl wedispatcher failes to start - Error posted below

2.I should access webdispatcher using with https port
3. How can i access webdispatcher servevr exisitng in XYZWEB.com using with XYZ.COM using https port ?
Do you think i should generate SSL Certificates for the both XYZ.COM and XYZWEB.COM ? If so i did that but may be i did not do correctly
Please help me , Your help is appreciated
Thanks,
Ravin

Hi Ravin,
how do you want to config ssl on your web dispatcher, termination or passing refer to http://help.sap.com/saphelp_nw70ehp1/helpdata/en/39/09a63d7af20450e10000000a114084/frameset.htm
can you post your .pfl file here?

Did you installed SAP crypto library at: \webdispdev\sapmnt
SYS\exe\run\sapcrypto.dll
2.I should access webdispatcher using with https port
that's a business requriement you'd check with the owner.
3. How can i access webdispatcher servevr exisitng in XYZWEB.com using with XYZ.COM using https port ?
the ssl server certificate should be applied for the domain which is used by the end user, not your server OS configuration, in your case, I assume it should be XYZ.com

How can we hide the URL with Webdispatcher after SSO redirect

Repost in correct forum
We have setup SSO with Kerberos and SPNEGO for NWBC and now we want to expose it to the internet via SAP Webdispatcher.
NWBC is on a singelstack ABAP system on server1 and we have configured a standalone J2EE system on server 2 for isuing the saplogon ticket.
This works fine with the redirect from icf NWBC -> Error Pages -> Logon Error -> Redirec to URL (Form Fields) http://server2:port/redirect/redirect.jsp
on server2 we have a java application (redirect/redirect.jsp) witch has %response.sendRedirect("http://server1:port/nwbc")%
Problem is that when the webdispatcher calls http://server1:port/nwbc the URL in the browser is hidden with MYDOMAIN.COM/nwbc but when the Logon-error (no saplogon ticket yet) is redirecting to http://server2:port/redirect/redirect.jsp the browser is showing the actual URL http://server2:port/redirect/redirect.jsp and also when returning to NWBC the browser is showing http://server1:port/nwbc.
And we don't wan't to expose hostnames (server1 and server2) to the internet.
I got this answer:
This question belongs to the SAP NetWeaver Application Server space, this space is for NWSSO topics only, the separately licensed product from SAP.
Regarding your question you have to configure Web Dispatcher for both AS JAVA and AS ABAP and refer to Web Dispatcher URLs only. That includes ICF node configuration and the redirect servlet. The URL generation in AS ABAP needs to be configured so that URLs are generated to point to the Web Dispatcher. Use table HTTPURLLOC for that.
But how do I set up webdispatcher for both ABAP http://server1:port/nwbc (this is working fine before SSO config.) and JAVA http://server2:port/redirect/redirect.jsp?
This is my profile on webdispatcher:

You can use Web Dispatcher for multiple systems, in your case one AS ABAP and one AS JAVA. See the documentation, Implement one webdispatcher for multiple systems - Basis Corner - SCN Wiki and Name-based virtual hosts and one SAP Web Dispatcher to access multiple SAP systems.

SAP Webdispatcher and URL redirect - 3 systems, one webdispatcher

Good day,
I have the following scenario, webdispatcher in the DMZ that redirects to Enterprise Portal internally.
There is a role in EP which is setup for webgui to 2 seperate ERP systems.
Is it possible to have 3 seperate redirects on the webdispatcher for the external address https://external:port/irj/portal, i.e for
1) host1:port/irj/portal
2) host2:port//sap/bc/gui/sap/its/webgui/!
3) host3:port//sap/bc/gui/sap/its/webgui/!
The portal content works fine, as soon as I access the webgui role, no content is displayed.
Thanks
Derek

Hi,
If you want to use a single web dispatcher for 3 back office systems (EP, ERP&, ERP2) you need to use release 7.2 at least.

WebDispatcher - http - https

Hello all,
we have install a WebDispatcher for load balancing between two portal server 7.00.
Now we must change the portal to https. We activate https on the portal and running now https.
How can i configure the WebDispacther itself, that all requests was forwarded to the https-url of th portal.
We want to stay on http with the Dispatcher, only the request should be forwarded to the https link of the portal.
Can somebody help me?

We solve the problem with the following parameter:

FPN configured for message server port

Hello,
I would like to configure my Consumer Portal to connect to my Producer on port :8101 (the default message server port of the Producer). However, each time I try with this conifguration FPN breaks and nothing works - can't browse the PCD or see remote roles via Identity Management (when I switch the config back to point to port :50000 in the Producer object on the Consumer it works fine again). I'm not using a SAP web dispatcher between the two portals but Producer portal is indeed listening on port :8101 since I can hit it directly. Is this a limitation of FPN?
My http trace shows an ABORT message when trying to connect with the :8101 configuration.
The 8101 port is necessary to be configured in order to leverage our clustered load balanced environment which has the 8101 message server port listening and redirecting to a cluster of servers.
Patrick

When using Remote Delta Links one can configure the SAP Message Server's RMI-P4 port (3901 by default) for RMI-P4 communication.
For the HTTP load balancing you cannot configure it to point to the HTTP port of SAP Message Server (8101 by default) only the application server's HTTP port on the Central Instance (e.g. 50000) can be used.
But don't bother yourselves with this, because SAP recommends using SAP Webdispatcher for HTTP load balancing in FPN scenario, so don't use SAP Message Server directly for HTTP load balancing in the FPN connection setup!

Hi,
SAP Web Dispatcher installation files can be found with the SAP Kernel in /sapmnt/<SID>/exe.
Required Files:
     icmbnd
     sapwebdisp
     icmadmin.SAR
SAP Crypto Libraries are also required if SSL is to be used with the Web Dispatcher. These can be obtained from the SAP software download center
e.g SAPCryptoToolkitHP/90000102.CAR

Refresh it, and it might work. sometimes, it never works and then it works fine after some time. I am not getting any tips to fix it.
In BI7 -
(SMICM) - https is enabled on port 443
(RZ10) for message server, http and https ports are open
(Visual admin)ports 50000 and 50001 are enabled

BPC via sapwebdisp/proxy

Hello,
This is a repost from another forum, but still the same question.
BPC 7.0 for Netweaver, connecting to a BI 7.01 system. (I might upgrade to 7.5 if forced).
I am trying to figure out if what I want to do is possible or if I am on the correct path.
We have a controlled ECC/BI/Portals enviorment and the only webaccess to our env is through sapwebdisp server outside of our SAP context. We are in the process of implementing BPC and I am wondering if I can use our same webdispatcher to re-direct/pass through all of my BPC information to the correct system.
user --> webdispatcher --> firwall ---> BPC .NET Server ---> BI Server
We would have
sapwebdisp:443/irj --> Portals Box
sapwebdisp:443/sap --> point to ECC
sapwebdisp:443/bw ---> point to BI
and
sapwebdisp:443/OSoft forward to BPC IIS Server port (80 or 443, does not matter),
Is this the best way to do it? Since BPC does not have a message server (just IIS), I am unsure if I can design it this way or if I should try some other tools for this.
We want to continue to have the webdispatcher as the only web access into all of our systems.
Any thoughts?
So I guess my real question is can I use webdispatcher for IIS servers, or is there another tool that will allow this.
Thanks,
