TFDSCOM Commands
Guidelines
•
filename must be a 101 type Edit file.
•
If filename does not already exist, it is created.
•
If filename already exists, then the new trace data is appended to the end of the
file.
Example
TRACE-FILE $DATA02.TRACEDAT.TRCEA014
TRACEHELPER
The TRACEHELPER command allows you to start or stop tracing, change the current
tracing level, or dump the circular trace buffer maintained in the TFDS helper memory
to a file, either for the TFDS helper process running on the specified processor, or for
all TFDS helper processes.
cpu
specifies the processor in which the TFDS helper process is running. Valid values
are 0 through 15.
ALL
specifies all TFDS helper processes
STOP
specifies tracing is to be stopped
0xtracelevel
specifies a 32-bit mask input as a hex value 0xtrace-level (e.g. 0x3B). Any
combination of these bits can be specified for tracelevel:
•
0xFFFFFFFF specifies tracing is to occur at all levels.
•
0x00000001 specifies that errors are to be logged. (This does not need to be
specified as all errors are always logged if tracing is enabled.)
•
0x00000002 specifies that state changes are to be traced.
•
0x00000004 specifies that incident data is to be traced.
•
0x00000008 specifies that incident data is to be traced in greater detail.
•
0x00000010 specifies that incident EMS message fields are to be traced.
•
0x00000020 specifies that entry into major TFDS helper functions is to be
traced.
•
0x00000040 specifies that entry into major TFDS helper functions is to be
traced in greater detail.
•
0x00000080 specifies that TFDSCOM-related tasks are to be traced.
