PTrace for the X25AM Subsystem
This section describes how to analyze traces using PTrace. It provides the PTrace
command syntax and fields of sample trace records. This section includes how to:
•
Record and display trace data
•
Use PTrace to determine which subsystem generated a trace file
•
Use PTrace commands, along with any special considerations for using these
commands, with the X25AM subsystem
•
Use SELECT keywords and mask bits
•
Create a sample trace file
•
Analyze X25AM traces
For more information about PTrace, see the PTrace Reference Manual.
Recording and Displaying Trace Data
Trace files contain a record of the communications between processes. Each
subsystem determines what information is recorded in its trace files. The type of events
recorded, the amount of detail, and the subsystem-specific parameters may vary.
You generate a trace file using the SCF TRACE command. The trace files that SCF
creates are unstructured and cannot be printed or displayed directly. You use PTrace to
display and examine the trace files. The PTrace program formats the data stored in the
unstructured trace files for output to terminals, printers, or disk files. Figure 6-1 on
page 6-2 shows the four general steps involved in recording and displaying trace data.
