About PTrace
The print trace (PTrace) utility formats data that is stored in unstructured trace files for
output to terminals, printers, and disk files. Trace files contain records of the
communications between processes.
Using PTrace, you can interpret information about processing activity collected from
processes, lines, and subdevices. This information can be used for troubleshooting.
Information for PTrace can be collected in one of two ways:
•
Interactively, with the Subsystem Control Facility (SCF) trace facility
•
Programmatically, with a management programming application that uses the
same trace facility as SCF
Each subsystem varies as to what is recorded and the amount of detail that is
included.
The information produced by a trace facility is stored in an unstructured Guardian file.
The PTrace program formats information from this file into a format that you can
examine. The formatted information can be sent to a terminal, a printer, or a disk file.
This manual includes only the PTrace specifics for the CP6100 subsystem. For more
information about the PTrace utility, see the PTrace Reference Manual.
