<h1 class="topictitle1">Control information written in a job log</h1>
<div><p>You can control what information the system writes in the job log.</p>
<div class="section"><p> To do this, you specify the LOG parameter on the <span class="cmdname">Create
Job Description (CRTJOBD)</span> command. You can change these levels
by using the <span class="cmdname">Change Job (CHGJOB)</span> command or the <span class="cmdname">Change
Job Description (CHGJOBD)</span> command. Three values make up the LOG
parameter: Message level, message severity, and message text level.</p>
<p>The
first value, message level, has the following levels: </p>
<dl><dt><strong>Level</strong></dt>
<dd><strong>Description</strong></dd>
<dt class="dlterm">0</dt>
<dd>No data is logged.</dd>
<dt class="dlterm">1</dt>
<dd>The only information to be logged is all messages sent to the job's external
message queue with a severity greater than or equal to the message severity
specified. Messages of this type indicate when the job started, when it ended,
and its status at completion.</dd>
<dt class="dlterm">2</dt>
<dd>The following information is logged: <ul><li>Level 1 logging information.</li>
<li>Any requests that result in high-level messages with a severity greater
than or equal to the severity specified. If the request is logged, all of
its associated messages are also logged.</li>
</ul>
</dd>
<dt class="dlterm">3</dt>
<dd>The following information is logged: <ul><li>Logging level 1 and 2 information.</li>
<li>All requests.</li>
<li>Commands run by a CL program if allowed by the <samp class="codeph">Log CL program
commands</samp> job attribute and the <samp class="codeph">Log</samp> attribute of
the CL program.</li>
</ul>
</dd>
<dt class="dlterm">4</dt>
<dd>The following information is logged: <ul><li>All requests and all messages with a severity code greater than or equal
to the severity specified, including trace messages.</li>
<li>Commands run by a CL program if allowed by the <samp class="codeph">Log CL program
commands</samp> job attribute and the <samp class="codeph">Log</samp> attribute of
the CL program. <div class="note"><span class="notetitle">Note:</span> A high-level message is one that is sent to the program
message queue of the program that receives the request. For example, QCMD
is an IBM-supplied request processing program that receives requests.</div>
</li>
</ul>
</dd>
</dl>
<p>The second value, message severity, specifies the severity
level in conjunction with the log level that causes error messages to be logged
in the job log. Values 0 through 99 are allowed.</p>
<p>The third value in
the LOG parameter, message text level, specifies the level of message text
that is written in the job log. The values are: </p>
<dl><dt class="dlterm">*SAME</dt>
<dd>The current value for the message text level does not change.</dd>
<dt class="dlterm">*MSG</dt>
<dd>Only message text is written to the job log (message help is not included).</dd>
<dt class="dlterm">*SECLVL</dt>
<dd>The message and the message help (cause and recovery) are written to the
job log.</dd>
