TRACE LINE Command
TRACE LINE Command
The TRACE LINE command initiates, modifies, or terminates trace mode on ATP6100
lines. Using TRACE, you can request capture of target-defined data items, alter trace
parameters, and end tracing. TRACE LINE is a sensitive command.
An SCF trace produces a trace file that can be displayed using PTrace commands.
The trace file is created by SCF. The PTrace utility is described in Section 7, PTrace
Facility for ATP6100.
Command Syntax for the TRACE LINE Command
The TRACE LINE command has the following syntax:
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
LINE line-name
designates the object to be traced. If you omit line-name, SCF traces the
assumed object (see the SCF Reference Manual for G-Series RVUs or SCF
Reference Manual for H-Series RVUs for details about the ASSUME command).
STOP [ , BACKUP ]
discontinues the trace currently in progress on the primary process. If you specify
BACKUP along with STOP, only the backup process trace is stopped.
BACKUP
specifies that the backup process should receive the trace request. The object
must be running as a process pair if you use this syntax. If the primary process is
being traced when a takeover by the backup process occurs, the trace of the
process continues. However, in this case, most events being traced before the
process switch are no longer traced because the process being traced is no longer
the primary process. If you omit BACKUP, SCF assumes the primary process.
