Part 2 of my "Reloaded-Series"! In the orginal post here TCPBinding seemed to be the solution. But it is not the best and in some cases just not usable. This only applies to large requests! Sabrina and Philippe, both colleagues in the current project, discovered something far better and much more interesting... What happnes here is DOS-attack-prevention ......

This error plagued me some time ago but then some change in the called service(i think they sped up processing...) was the solution. But in my new project it happend again. We call a WebService hostet on WebLogic. No problem if the traffic is low and only few calls are made. But then calls increased and *boom*. Not again! It took us several days to ......

A WCF Service we call from BizTalk using WCF BasicHTTP usually works fine but all of a sudden it started returning 401 errors for some calls while others continued working as expected so it could not have been a "real" 401. The difference was the size of the message. One parameter of the service is a rather complex object. In the cases we got a 401 ......

A strange error occured recently on our BizTalk. It suddenly showed up in the EventLog and the Orchestration got suspended. "Index was outside the bounds of the array" happened at the Receive shape connected to a Request-Response-Port where we called a WebService. It had worked properly a day before. The response message from the service we called was ......

It's been a long time... I am very busy in my new project in Switzerland. Zürich is great! :-) On one of our testing-environments the EventViewer of BTS Admin Console suddenly didn't show events anymore. All categories (Application, System, etc.) were just blank. The EventViewer of Windows Server 2008 still worked but I prefer the one in BTS as it is ......

Two posts on one day? Is he on his holidays? Yes! We had a lot of trouble with this error: ...Error Description: System.ServiceModel.Communi... An error (The request was aborted: The request was canceled.) occurred while transmitting data over the HTTP channel.... You find a few posts about it in the www but the answers are somewhat conflicting ......

You created classes from your XML-Schemas (using XSD.exe for example) and want to use them in BizTalk. There may be several reasons for and against doing it. But I do not want to discuss that here. Just assume you want to do it. ;-) After you deployed your BizTalk App and start sending the first messages to your ReceiveLocation with an XML Receive Pipeline ......

Pekka from Frends gave me the opportunity to have a look at the beta-version of their Helium 2.0. For all of you, who don't know the tool: Helium is a web-application that collects management-data from BizTalk which you usually have to tediously collect yourself, like performance-data (throttling, throughput (like completed Orchestrations/hour), other ......

A WCF Service I provided took a very simple data contract as parameter (containing one string and one int...) and had a very simple task to do. A .NET 3.5 client was created using the VS2008 feature "Add Service Reference". Everything worked as expected. Then a slight change came in: The client was expected to run on machines with .NET 2.0 only. So ......

Imagine a huge BizTalk-project. Loose coupling has been taken very seriously and a lot of this is done via the MessageBox and subscriptions. Very complex workflows are distributed over lots of Orchestrations. Commands in the messages tell the system which Orchestration to call next, which backend-system to call, etc. Nice... :-) Then one day during ......
