TRACE Command
TRACE Command
TRACE is a sensitive command that initiates trace-data collection on the specified
object. You can use traces as a diagnostic tool.
An SCF trace produces a trace file that can be displayed by using the commands
available in the PTrace program. The Subsystem Control Point (SCP) creates the trace
file. Refer to the PTrace Reference Manual for detailed information about PTrace.
TRACE MON Command
The TRACE MON command executes a trace on the LANMON process.
Command Syntax
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
MON lanmon-name
specifies the LANMON process on which a TRACE is to be performed. LANMON
names have the form $ZZLAN.#ZLMnn where nn indicates the particular processor
in which the LANMON is running.
STOP
discontinues the trace currently in progress.
BULKIO | NOBULKIO
designates whether TRACE should use bulk I/O for tracing. BULKIO specifies that
the TRACE collector use bulk I/O to write data to the disk file, reducing the number
of missing frame errors reported by PTrace.
A limitation of bulk I/O is that only one user can access the file at a time. If shared
access of the trace file is needed while the trace is active, specify NOBULKIO.
