How can a job’s execution priority be modified ?

  1. PRTY parameter

  2. JOBCLASS parameter

  3. RUNTIME parameter

  4. PRIQTY parameter


Correct Option: A

AI Explanation

To answer this question, you need to understand how job execution priority is determined and how it can be modified.

In many operating systems, including some mainframe systems, job execution priority is determined by assigning a priority value to each job. This priority value determines the order in which jobs are executed by the system.

The correct answer is A) PRTY parameter. The PRTY (Priority) parameter is used to modify a job's execution priority. By specifying a higher priority value, the job will be given higher execution priority, and vice versa. This allows the system administrator or programmer to control the order in which jobs are executed and ensure that critical or time-sensitive jobs are given higher priority.

Let's go through each option to understand why they are correct or incorrect:

Option A) PRTY parameter - This option is correct because the PRTY parameter is used to modify a job's execution priority.

Option B) JOBCLASS parameter - This option is incorrect. The JOBCLASS parameter is used to specify the job class or category to which a job belongs. It does not directly modify the execution priority of a job.

Option C) RUNTIME parameter - This option is incorrect. The RUNTIME parameter is used to specify the maximum runtime allowed for a job. It does not directly modify the execution priority of a job.

Option D) PRIQTY parameter - This option is incorrect. There is no standard parameter called PRIQTY in mainframe systems that is used to modify a job's execution priority.

Therefore, the correct answer is A) PRTY parameter. This option is correct because the PRTY parameter is used to modify a job's execution priority.
