Traces in Startup JCL
When a problem occurs while Connect:Direct® is running, you can use a variety of traces to gather information to diagnose the problem and record events as they happen. Based on the trace specified, the Connect:Direct trace output is directed to various ddnames. For more information on traces, see Isolating Problems.
