Web Dispatcher Not Working

[Former Member]

Dear All,

I have configured the web dispatcher on ECC 6.0 with Java Stack (ABAP and JAVA stack with different SID and separate database MSSQL2005).

We have a webdynopro application developed on ABAP Stack that works fine. I have to redirect the URL of my application that is too long right now to a small URL like www.xyz.com.

Web Dynopro is confugured using the below steps in the link.

/people/prakash.singh4/blog/2005/08/16/how-to-setup-webdispatcher-to-load-balance-portal-in-a-clustered-environment

Now whenever I start the webdispatcher service it starts fine but then the portal not even opens sometime.

Below is the output of the command sapwebdisp pf=sapwebdisp.pfl -checkconfig

I'm not sure this is really a Web Dynpro ABAP appropriate question. You should probably post in the Portal or one of the System Admin forums as this is really about the setup of the Web Dispatcher.
