Question

Mvs command to display all the jobs using more that 5 % of spool

A. $DSPL,JOBS>5
B. $DSPL,SPOOL>5
C. $DSPL,JOBS%>5
D. None of these

Answer

A. $DSPL,JOBS>5

Explanation

In the MVS (Multiple Virtual Storage) operating system, the $DSPL command is used to display information about jobs, output, and devices managed by JES2 (Job Entry Subsystem 2). The $DSPL command allows you to specify various parameters to filter the displayed information based on specific criteria.

To display all the jobs using more than 5% of the spool space, you would use the command:

$DSPL,JOBS>5

Here’s how the command works:

  1. $DSPL: This is the base command that instructs JES2 to display information.
  2. JOBS: This parameter specifies that you want to display information about jobs.
  3. >5: This is a filtering condition that indicates you only want to see jobs that are using more than 5% of the spool space.

When you execute the command $DSPL,JOBS>5, JES2 will display a list of all the jobs that are currently using more than 5% of the total spool space allocated to the system. This command helps you identify jobs that are consuming a significant amount of spool resources, which can be useful for performance monitoring and troubleshooting.

Option B, $DSPL,SPOOL>5, is incorrect because SPOOL is not a valid parameter for the $DSPL command. Option C, $DSPL,JOBS%>5, is also incorrect because the percentage sign (%) is not used in this context. Option D, “None of these,” is incorrect since option A provides the correct command.

In summary, the MVS command $DSPL,JOBS>5 is used to display all the jobs that are using more than 5% of the spool space, allowing you to monitor and manage system resources effectively.
