Configuring BizTalk WCF Timeout Values on a Binding

There are a number of timeout settings available in WCF bindings. Setting these timeout settings correctly can improve not only your service’s performance but also play a role in the usability and security of your service. The following timeouts are available on WCF bindings:

1. OpenTimeout
2. CloseTimeout
3. SendTimeout
4. ReceiveTimeout

Open Timeout :  This property represents the amount of time a channel open operation has to complete.

Send Timeout :  Use this property to set the amount of time that a send operation has to complete. When used as part of a solicit-response scenario, this value encompasses the total amount of time for the interaction to complete. If we are sending a large message, we may need to increase this timeout to allow for the request and response messages to be processed within this window.

Close Timeout :  A time-stamp that is used to indicate the amount

Receive Timeout : Used by the Service Framework Layer to initialize the session-idle timeout which controls how long a session can be idle before timing out.

Following are C#, Config and BizTalk e.g. :

C#

• public static void Main()  
•         {  
•             Uri baseAddress = new Uri("http://localhost/BizTalkLive/BizTalkService");  
• 
  
•             try  
•             {  
•                 ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService));  
• 
  
•                 WSHttpBinding binding = new WSHttpBinding();  
•                 binding.OpenTimeout = new TimeSpan(0, 10, 0);  
•                 binding.CloseTimeout = new TimeSpan(0, 10, 0);  
•                 binding.SendTimeout = new TimeSpan(0, 10, 0);  
•                 binding.ReceiveTimeout = new TimeSpan(0, 10, 0);  
• 
  
•                 serviceHost.AddServiceEndpoint("ICalculator", binding, baseAddress);  
•                 serviceHost.Open();  
• 
  
•                 // The service can now be accessed.  
•                 Console.WriteLine("The service is ready.");  
•                 Console.WriteLine("Press <ENTER> to terminate service.");  
•                 Console.WriteLine();  
•                 Console.ReadLine();  
• 
  
•             }  
•             catch (CommunicationException ex)  
•             {  
•                 // Handle exception ...  
•             }  
•         }

BizTalk Console

Client-side Timeouts:

Used: SendTimeout, OpenTimeout, CloseTimeout

Not Use: ReceiveTimeout

Service-side Timeouts: SendTimeout, OpentTimeout, CloseTimeout are the same as on the client-side except ReceiveTimeout.
