WCF XMS First Failure Support Technology ( FFST )

We can collect detailed information about what various parts of the IBM MQ code is doing by using IBM MQ trace. XMS FFST has its own configuration and output files for the WCF custom channel.

XMS FFST trace files are traditionally named using the base name and process ID format of: xmsffdc pid_date.txt, where pid is the process ID and date is the time and date.

As XMS FFST trace files can still be produced in parallel with WCF custom channel XMS FFST files, the WCF custom channel XMS FFST output files have the following format to avoid confusion: wcf ffdc pid_date.txt, where pid is the process ID and date is the time and date.

This trace output file is created in the current working directory by default, but this destination can be redefined if necessary.

The WCF custom channel with XMS .NET trace header is similar to the following example:

************* Start Display XMS WCF Environment *************
Product Name :- value
WCF Version  :- value
Level  :- value
************* End Display XMS WCF Environment *************

The FFST trace files are formatted in the standard way, without any formatting that is specific to the custom channel.
