For the .NET implementation of XMS, one FFDC file is produced for each FFDC.
FFDC files are stored in human readable text files and have names of the form xmsffdc<processID>_<DateTime>.txt. Files start with the date and time that the exception occurred, followed by the exception type, and include a unique short probeId, which can be used to locate where this FFDC occurred.
You do not need to carry out any configuration to turn FFDC on. By default, all FFDC files are written to the current directory, but you can, if required, specify a different directory by changing ffdcDirectory in the Trace section of the application configuration file. In the following example, all trace files are logged to the directory c:client\ffdc:
<IBM.XMS> <Trace ffdc=true ffdcDirectory="c:\client\ffdc"/> </IBM.XMS>
You can disable trace by setting ffdc to false in the Trace section of the application configuration file.
If you are not using an application configuration file, FFDC is on and trace is off.
