TRACE Command
The TRACE command has the following syntax for tracing the network control process
($NCP):
/ OUT file-spec /
causes any SCF output generated for the command to be directed to the specified
file.
PATH path-name
is the device name of the path to be traced.
LINE line-name
is the device name of the line to be traced.
BACKUP
specifies that only the backup path should have its trace started or stopped. If
omitted, specifies that only the primary line is to be traced. The object must be
running as a process pair if this syntax is used. If the primary path is being traced
when a takeover by the backup path occurs, the trace of the same path continues.
However, most events that were being traced prior to the path switch will no longer
be traced because the path being traced is no longer the primary. If neither path is
designated, the primary path is traced.
COUNT count
count is an integer in the range -1 to (32K -1). It specifies the number of trace
records to be captured. If COUNT is not specified (or is specified as -1), records
are accumulated until the trace is stopped.
NOCOLL
indicates that the trace collector process should not be initiated. The disk file is to
be written to by the operating system.
