Trace Tab
To view the trace file for the selected map, click the Trace tab on the organizer
window or use any text editor to view the mapname.mtr file in the specified
directory.
The trace file is a text file that records map execution progress. Input data, output
data, or both input and output data may be included in a trace file. The trace file
should only be used for debugging purposes, because performance is impacted.
The map settings are used to enable tracing.
To create a trace file
1 Select the map.
2 From the Map menu, choose Settings.
3 Enable tracing by setting the MapTrace > Switch to On.
4 Specify the desired MapTrace settings.
5 Click OK.
The trace file is created as specified after the map is compiled and executed. After
you run a map, the trace file can be viewed on the Trace tab in the organizer
window.
A trace file of input messages contains a message for each input data object that
shows:
♦ The level of the object in the card
♦ The offset of the data object in the data stream
♦ The length of the data object
♦ The component number of the data object
♦ The index of the component
♦ A portion of the actual data
♦ The name of the type to which it belongs
