<p>The Create Class command creates a class object and specifies the attributes to be contained in the class. The class defines the processing attributes for jobs that use the class. The class used by a job is specified in the subsystem description routing entry used to start the job. 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.

<h3>Run priority (RUNPTY)</h3>
|

<p>Specifies the run priority of jobs that use the class. 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.
|
||
|
|
</p>
|
||
|
|
<p>This value represents the relative, not absolute, importance of the job. For example, a job with a run priority of 25 is <b>not</b> twice as important as one with a run priority of 50.

<h3>Time slice (TIMESLICE)</h3>
|
||
|
|
<p>Specifies the maximum amount of processor time (in milliseconds) given to each thread in a job using this class before other threads in a job or other jobs are given the opportunity to run. 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.

<p>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 would be the amount of time the system user would 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.

<h3>Maximum temporary storage (MAXTMPSTG)</h3>
|

<p>Specifies the maximum amount of temporary (auxiliary) storage (in kilobytes) 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.

<p>This command creates a class called CLASS1. The class is stored in the current library specified for the job. The user text 'This class for all batch jobs from Dept 4836' describes the class. The attributes of this class provide a run priority of 60 and a time slice of 900 milliseconds. If the job has not finished running at the end of a time slice, it is eligible to be moved out of main storage until it is allocated another time slice. The defaults for the other parameters are assumed.
