DUMP Command
Exchange/SNA Commands

If you omit the MODE parameter, only the length of each trace record (the
length of the RU plus 13) is listed. No data or control fields are listed.
LU { lu-number | ALL }
specifies the logical units (LUs) whose trace records are to be listed. You can
examine the low-order three bits of the FLAGS field to determine which LU is
being used for a given data stream.
If you specify a single LU number, only the trace records for which that LU
was a source or destination are listed.
If you specify ALL, all trace records for all LUs are listed.
If you omit this parameter, trace records for all LUs are listed.
Considerations The DUMP command formats and lists the contents of a trace file. The trace file must
already exist. You can list a trace file that is still in use. In this case, the most recent
trace records are still in the trace server buffer and have not yet been written to the
trace file. Therefore, the most recent trace records are not included in the output of the
DUMP command. To view the most recent trace records, you must first stop the trace
server, using the TRACE command. For more information on the trace server and the
trace file, see the TRACE command described later in this section.
DUMP Command With No Optional Parameters
If you use the DUMP command and omit all optional parameters, a summary of the
trace file is displayed on the home terminal (or the file specified in the OUT option of
the RJECIS command).
Output to a Printer
To format the trace file and list it on a printer, specify the name of a spooler location as
the output file. For example, to send the output to a printer named “lazer” controlled
by a spooler named “$s”, you would specify the output file as $s.#lazer.
Errors
If an error occurred, the ERROR field in the trace record contains the corresponding
error number. An error number of three zeros (000) indicates no error occurred. For
the meaning of the error numbers, see Section 4.
