Hi everybody.

I had already installed Wed Dispatcher in a DMZ and configured it.

So, I tried to access by using dial line and the following error was showed:

500 Dispatching Error


Error: -26

Version: 7000

Component: HTTP_ROUTE

Date/Time: Mon Nov 27 19:50:38 2006

Module: http_route.c

Line: 3089

Server: <host>_<instance_name>_<instance_number>

Error Tag:

Detail: no valid destination server available for '!ALL' rc=13

Does anyone know what is should be?

The dispatcher said, it did not know how to forward the request to an upstream application server. Maybe a problem in your config file.

Hi Patrick.

I looked the trace file at Web Dispatcher and I verified that it is not connecting to Message Server. Do you know where I could find the port of my message server? I mean which port do I need to set up into config file of Web Dispatcher?

I found the host and port of message server in: http://<host>:<port>/sap/monitoring/SystemInfo

Is it right?

Follow the trace:
