Problem determination on the WCF custom channel for IBM MQ

We can use IBM MQ trace to collect detailed information about what various parts of the IBM MQ code is doing. When using Windows Communication Foundation (WCF), a separate trace output is generated for the WCF custom channel trace integrated with the Microsoft WCF infrastructure trace.

Fully enabling trace for the WCF custom channel produces two output files:
  1. The WCF custom channel trace integrated with the Microsoft WCF infrastructure trace.
  2. The WCF custom channel trace integrated with XMS .NET.
By having two trace outputs, problems can be tracked at each interface using the appropriate tools, for example:

  • WCF problem determination using suitable Microsoft tooling.
  • IBM MQ MQI client issues using the XMS trace format.

To simplify trace enablement, the .NET 3 TraceSource and XMS .NET trace stack are both controlled using a single interface as described in: WCF trace configuration and trace file names: SOAP/JMS interface.
