Activating Traces 
You can activate the trace function for the gateway and for external programs.
You have the following options via the menu option Goto ® Trace ® Gateway:
· Display file / Reset file
You can display or reset the gateway trace file (gateway reader, default name of trace file: dev_rd).

Every time the gateway is restarted, the old trace file is stored under the name <name>.old (therefore, usually dev_rd.old). The dev_rd file is overwritten.
· Increase trace level / Decrease trace level
You can increase ore reduce the trace level (for details see parameter rdisp/TRACE).
·
Use trace logging
to locate sporadic or tricky errors. This is described in detail in the
Trace Logging
documentation.
You can activate and deactivate tracing for communication with external programs by choosing Goto ® Trace ® External programs ® Activate or Deactivate.
Refer to Error Analysis.
