TRACE PIF Command
Example
This example traces DIH state-machine operations and messages between a
LANMON and DIH for the PIF named G11123.0.B. The maximum length of the traced-
data record is 2048 bytes. The information is saved in the file named TRFIL1.
TRACE PIF $ZZLAN.$ZZLAN.G11123.0.B, RECSIZE 2048, &
SELECT (SMACH, LMOMSG), TO $M2.SUBV.TRFIL1
TRACE PROCESS Command
The TRACE PROCESS command initiates a trace on the specified LANMAN process.
Command Syntax
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
PROCESS
process-name
specifies the process for which a trace is to be initiated. For the LANMAN process,
process-name is $ZZLAN.
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 BULKIO 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.
Bulk I/O tracing is faster and should eliminate most data loss. The default is
BULKIO. BULKIO cannot be used with NOCOLL.
