|
|
<div><p>Use the Display Object Description (DSPOBJD) command to view a
|
|
list of history log files.</p>
|
|
<div class="section"> <p>The history log files are copies of all the messages that are
|
|
sent to the message queue QHST. When the size of the current history log exceeds
|
|
its size limitation, the system creates a new file. The files reside in library
|
|
QSYS and begin with the letters QHST, followed by a number. The format that
|
|
is used is QHST<samp class="codeph">yydddn</samp>. The <samp class="codeph">yydddn</samp> represents
|
|
the date of the first message in the file, where <samp class="codeph">yy</samp> is the
|
|
year and <samp class="codeph">ddd</samp> is the sequential number of the day of the year
|
|
(for example, February 1 would be 032). The <samp class="codeph">n</samp> that is appended
|
|
at the end is a sequence number; this sequence number is only incremented
|
|
when more than one QHST file is generated within one day.</p>
|
|
<p>To display
|
|
the list of history logs and to view its contents:</p>
|
|
</div>
|
|
<ol><li><span>Type <tt>WRKF QHST*</tt> from any command line.</span></li>
|
|
<li><span>Select option 5 to display the contents of the file.</span></li>
|
|
</ol>
|
|
<div class="section"> <div class="note"><span class="notetitle">Note:</span> The system copies the messages in the QHST message queue to
|
|
the history log files and then removes them from the QHST message queue. The
|
|
DSPLOG command uses the history log files to show the messages sent to the
|
|
QHST message queue.</div>
