PTrace Features for Selecting and Displaying Trace
Records
1. Start the trace with the SCF or CMI TRACE command or programmatically with
SPI.
The TRACE command allows you to specify such parameters as the size of the
trace records and the name and maximum size of the trace file.
2. Collect the trace data. Send and receive the data or perform other operations that
are related to the problem that you are analyzing.
3. Stop the trace with the CMI or SCF TRACE command or programmatically with
SPI.
4. Display the trace file with PTrace or CMI PTrace mode. (Only PTrace is described
in this manual.)
PTrace Features for Selecting and Displaying Trace Records
PTrace provides options for selecting trace records for display, so you can suppress
those that do not relate to the problem you are investigating.
