In a mainframe environment, how do you ensure that high-priority jobs are executed before low-priority jobs?
- Allocating more CPU time to high-priority jobs
- Setting the JOBCLASS parameter
- Specifying execution order in the JCL
- Using job scheduling software
High-priority job execution is typically managed by job scheduling software
