<div><p>Job run-time attributes are contained in the class object that
|

|
|
is specified in the (<span class="parmname">CLS</span>) parameter in the routing entry.
|
||
|
|
If a job consists of multiple routing steps, the class used by each subsequent
|
||
|
|
routing step is specified in the routing entry used to start the routing step.
|
||
|
|
If the class does not exist when the routing entry is added, a library qualifier

must be specified because the qualified class name is kept in the subsystem

description.</p>
|
||
|
|
<p>Run-time attributes that are included in a routing entry class are:</p>
|
||
|
|
<dl><dt class="dlterm">Run priority (<span class="parmname">RUNPTY</span>)</dt>
|
||
|
|
<dd>The run priority is a value ranging from 1 (highest priority) through
|
||
|
|
99 (lowest priority) that represents the priority at which the job competes
|
||
|
|
for the processing unit relative to other jobs that are active at the same
|
||
|
|
time. For multi-threaded jobs, the run priority is also the highest run priority
|
||
|
|
allowed for any thread within the job. Individual threads within the job may
|
||
|
|
have a lower priority.</dd>
|
||
|
|
</dl>
|
||
|
|
<dl><dt class="dlterm">Time slice (<span class="parmname">TIMESLICE</span>)</dt>
|
||
|
|
<dd>This is the time slice establishes the amount of time needed by a thread
|
||
|
|
in a job to accomplish a meaningful amount of processing. At the end of the
|
||
|
|
time slice, the thread might be put in an inactive state so that other threads
|
||
|
|
can become active in the storage pool.</dd>
|
||
|
|
</dl>
|
||
|
|
<dl><dt class="dlterm">Default wait time (<span class="parmname">DFTWAIT</span>)</dt>
|
||
|
|
<dd>This specifies the default maximum time (in seconds) that a thread in
|
||
|
|
the job waits for a system instruction, such as the LOCK machine interface
|
||
|
|
(MI) instruction, to acquire a resource. This default wait time is used when
|
||
|
|
a wait time is not otherwise specified for a given situation. Normally, this
|
||
|
|
is the amount of time the system user might be willing to wait for the system
|
||
|
|
before the request is ended. If the wait time for any one instruction is exceeded,
|
||
|
|
an error message can be displayed or it can be automatically handled by a
|
||
|
|
Monitor Message (MONMSG) command. </dd>

</dl>
|
||
|
|
<dl><dt class="dlterm">Maximum CPU time (<span class="parmname">CPUTIME</span>)</dt>
|
||
|
|
<dd>This specifies the maximum processing unit time (in milliseconds) that
|
||
|
|
the job can use. If the job consists of multiple routing steps, each routing
|
||
|
|
step is allowed to use this amount of processing unit time. If the maximum
|
||
|

time is exceeded, the job is ended. </dd>

</dl>
|
||
|
|
<dl><dt class="dlterm">Maximum temporary storage (<span class="parmname">MAXTMPSTG</span>)</dt>
|
||
|
|
<dd>This specifies the maximum amount of temporary (auxiliary) storage that
|
||
|
|
the job can use. If the job consists of multiple routing steps, this is the
|
||
|
|
maximum temporary storage that the routing step can use. This temporary storage
|
||
|
|
is used for storage required by the program itself and by implicitly created
|
||
|
|
internal system objects used to support the job. It does not include storage
|
||
|
|
in the QTEMP library. If the maximum temporary storage is exceeded, the job
|
||
|
|
is ended. This parameter does not apply to the use of permanent storage, which
|
||
|
|
is controlled through the user profile. </dd>

|
</dl>
|
||
|
|
<dl><dt class="dlterm">Maximum threads (<span class="parmname">MAXTHD</span>)</dt>
|
||
|
|
<dd>This specifies the maximum number of threads that a job using this class
|
||
|
|
can run with at any time. If multiple threads are initiated simultaneously,
|
||
|
|
this value may be exceeded. If this maximum value is exceeded, the excess
|
||
|
|
threads will be allowed to run to their normal completion. Initiation of additional
|
||
|
|
threads will be inhibited until the maximum number of threads in the job drops
|

below this maximum value.</dd>

<dl><dt class="dlterm">Text description (<span class="parmname">TEXT</span>)</dt>

<dd>This specifies the text that briefly describes the object. This is an
|

attribute of the class object when it is created, but it is not a run-time
|

|
|
attribute for a job.</dd>

</dl>

<dl><dt class="dlterm">Authority (<span class="parmname">AUT</span>)</dt>

<dd>This specifies the authority you are giving to users who do not have specific
|

|
|
authority for the object, who are not on an authorization list, and whose
|
||
|
|
group profile or supplemental group profiles do not have specific authority
