SNMP Agent PTrace Facility
Running PTrace
Although the PTrace Reference Manual covers this subject in more detail, the
descriptions that follow should be enough to get you started running PTrace.
Starting a Noninteractive PTrace Session
The syntax of the TACL or SCF RUN command for PTrace is:
PTRACE [ /run-option-list ] [ ptrace-command ] ...
run-option-list
is one or more NonStop Kernel run options, as described in the TACL Reference
Manual. Although other run options are allowed, the following options have special
significance for PTrace:
IN file-name
designates the initial source for PTrace command input for a session. If you
omit the IN option, the input source defaults to the input file for the TACL
process through which you started PTrace (usually a terminal).
NOWAIT
indicates that TACL or SCF does not wait while PTrace runs but returns a
command interpreter prompt after sending the startup message to PTrace. If
you omit this option, TACL or SCF pauses while PTrace runs.
OUT [ file-name ]
designates the initial destination for PTrace display output for the session. You
can use this formatted file for your problem diagnosis. If you omit the OUT
option, the output destination defaults to the output file of the TACL or SCF
process through which you started PTrace (usually a home terminal).
If you specify the OUT option and omit file-name, PTrace output is
discarded. If you specify an existing disk file, the file's data is purged, and new
data is written to the file. If the file does not exist, TACL creates an EDIT file
with an extent size of 4 pages for the primary extent and 16 pages for
secondary extents (maximum of 400 pages). You can have up to 16 secondary
extents for a maximum file size of 260 pages. If you will need a file larger than
260 pages, you must use a previously created file. When the PTrace disk file
reaches end of file (EOF), PTrace stops.
