Selecting Trace Events Supported by TSCODE
Selecting Trace Events Supported by TSCODE
The first step in tracing a GDSX process is to decide what events you want to trace.
Then determine from Table 2-4 which of these events TSCODE automatically generates
trace records. Read the descriptions of events traced in the fourth column of the table,
checking for those events you want to trace. Make a note of the trace classes (a class
includes several event types) in the first column in which the events fall.
When you start the trace, you directly or indirectly (by means of SCF) set the
appropriate trace^control^flags (or auto^trace^flag) for these trace classes. (See
"Turning On the Trace Facility" on page 2-81.)
