<div><p><span>Considerations regarding the

job log maximum size and the resulting job actions might help you solve the

||
|

problem.</span></p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Job log maximum size</h4><p>If you are having problems
|
||
|
|
with storage consumption, you might need to change the job log maximum size
|
||
|
|
on the server job. You should specify a relatively small size for the job
|
||
|
|
log to avoid consuming excessive storage and, in some cases, excessive processing
|
||
|
|
time. These types of resource consumption occur when the system produces job
|
||
|
|
logs. For example, if a repetitive error occurs on a long running server job,
|
||
|
|
your job log fills up with repetitive messages and increases your storage
|
||
|
|
consumption level.</p>
|
||
|
|
<p>The value specified for the <em>Job message queue
|
||
|
|
maximum size</em> (JOBMSGQMX) parameter for the job indicates the size of the
|
||
|
|
job log. This value, along with the rest of the job's properties, is given
|
||
|
|
to the job when the job is started. Some server jobs specify this value in
|
||
|
|
the job description used by the job. Other server jobs specify this value
|
||
|
|
by defaulting to the setting of the QJOBMSGQMX system value. </p>
|
||
|
|
<p>The recommended
|
||
|
|
value for the <em>JOBMSGQMX</em> parameter is 8 MB. You cannot change the value
|
||
|
|
for this parameter by using the Change Job (CHGJOB) command. However, you
|
||
|
|
can change the value by accessing the parameter through the job description
|
||
|
|
using the Change Job Description (CHGJOBD) command.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Job log full action</h4><p>When the job log reaches its
|
||
|
|
maximum capacity as determined by the <em>JOBMSGQMX</em> parameter, several
|
||
|
|
different actions can occur depending on the value specified in the <em>Job
|
||
|
|
message queue full action</em> (JOBMSGQFL) parameter for the job. In most cases,
|
||
|
|
the job description indicates *WRAP as the default value. Many server jobs
|
||
|
|
specify this value in the job description used by the jobs.</p>
|
||
|
|
<p>You should
|
||
|
|
verify that *WRAP is specified for the JOBMSGQFL parameter by accessing the
|
||
|
|
job description. This value ensures that the job log messages overlay one
|
||
|
|
another when the job log reaches its maximum capacity. Be aware that other
|
||
|
|
values, such as *NOWRAP, can cause the server job to end when the job log
|
||
|
|
reaches its maximum capacity.</p>
