WCF Service with large parameters

Question

I've looked at a number of similar topics on SO, but haven't found one that helps with this.

Have a WCF service that takes in XML to process. The XML file I'm reading from is ~600K.

The call works for small xml files (most of the time), but on the larger files I get the error:

System.ServiceModel.Security.MessageSecurityException:
An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.

where the inner exception is:

System.ServiceModel.FaultException:
The message could not be processed. This is most likely because the action 'http://tempuri.org/ISapListener/ProcessSapRoles' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

Like I say... it works for small files, and my open, send, receive, close, and inactivity timeouts are all set to 10 minutes. It fails in about 20-30 seconds.

Also, the clock on the server and client are perfectly in sync (I've seen that posted as an answer).

My config files as they currently stand (I've played with a lot of settings):

Server:

<bindings>
  <wsHttpBinding>
    <binding name="wsHttpBinding_Custom" closeTimeout="00:00:10"
             openTimeout="00:01:00" receiveTimeout="00:10:00"
             sendTimeout="00:10:00" bypassProxyOnLocal="false" 
             transactionFlow="false" hostNameComparisonMode="StrongWildcard"
             messageEncoding="Text" textEncoding="utf-8"

                 negotiateServiceCredential="true"
                 algorithmSuite="Default" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>
<services>
  <service behaviorConfiguration="CSA.GS3.Services.SapListenerBehavior" 
           name="CSA.GS3.Services.SapListener">
    <endpoint address="" binding="wsHttpBinding"  
              bindingConfiguration="wsHttpBinding_Custom" 
              contract="CSA.GS3.Services.ISapListener">

Client:

I do have tracing enabled on the service, but I can't make sense out of the log files.

Other exceptions I've received while playing with the config settings:

System.ServiceModel.Security.SecurityNegotiationException
Secure channel cannot be opened because security negotiation with the remote endpoint has failed.

and

System.ServiceModel.ServiceActivationException
The requested service, 'http://../SapListener.svc' could not be activated.

Answer 1

If you think being able to make sense out of log files will help here, use svcTraceViewer. Just make sure you've actually set up tracing correctly. I have an article on my blog about this. svcTraveViewer Debugging WCF Services

As regards large payloads, you may want to take a look at this MSDN article. http://msdn.microsoft.com/en-us/library/ms733742.aspx

In particular Streaming Data.

Answer 2

System.ServiceModel.ServiceActivationException
The requested service, 'http://../SapListener.svc' could not be activated.

This could be a compilation error ou invalid configuration.

Is it WCF 4.0? Then you could remove your custom configuration and use automatic bindings. I also suggest you to try a binding other than wsHttpBinding, like basicHttpBinding.

Answer 3

I was able to get this to work with the following configuration:

Server:

<bindings>
  <wsHttpBinding>
    <binding name="wsHttpBinding_Custom"
             closeTimeout="00:10:00"
             openTimeout="00:10:00"
             receiveTimeout="00:10:00"
             sendTimeout="00:10:00"
             maxReceivedMessageSize="2097152"
             bypassProxyOnLocal="false" transactionFlow="false" 
             hostNameComparisonMode="StrongWildcard"
             maxBufferPoolSize="2097152" messageEncoding="Text"
             textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
      <readerQuotas maxDepth="32" maxBytesPerRead="4096" 
                    maxNameTableCharCount="16384" />
      <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
      <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None" 
                   realm="" />
        <message clientCredentialType="Windows" negotiateServiceCredential="true" 
                 algorithmSuite="Default" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

Client:

<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_ISapListener1" closeTimeout="00:10:00"
             openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
             bypassProxyOnLocal="false" transactionFlow="false" 
             hostNameComparisonMode="StrongWildcard"
             maxBufferPoolSize="2097152" 
             maxReceivedMessageSize="2097152"
             messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
             allowCookies="false">
      <readerQuotas maxDepth="32" maxBytesPerRead="4096" 
                    maxNameTableCharCount="16384" />
      <reliableSession ordered="true" inactivityTimeout="00:10:00"
                       enabled="false" />
      <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
                   realm="" />
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
                 algorithmSuite="Default" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

The only difference I can see is that I bumped up the maxReceivedMessageSize and maxBufferPoolSize... maybe I'm missing something else? If that was the issue, then the problem was that my overhead for the call was adding an additional 400+K to the 600K xml data I was sending

如果可能并为客户端所接受，您可以将文件分解为较小的块，然后进行发送，前提是您没有客户端的数字证书等和排序选项。
