DFSMSCE0 TM/MSC Message Routing exit trace

The DFSMSCE0 TM/MSC Message Routing exit trace can be activated individually for each exit entry point that processes a message routing request. This trace is useful for diagnosing problems in both the user exit and in IMS.

The DFSMSCE0 TM/MSC Message Routing Exit trace writes a 6701-MSEA log record when the exit is entered, and a 6701-MSEB log record when the exit returns to IMS to process the reroute request. The following information is traced:

  • Exit parameter area, DFSMSCEP
  • 512 byte work area
  • Message
  • Message prefix
  • Message segment being inserted
  • Other work area storage
