Explain a scenario where setting job priorities and classes using JCL job scheduling options can be crucial for efficient job execution.
- When jobs have dependencies on other jobs
- When jobs need to be executed at specific times
- When jobs require different levels of system resources
- When there are multiple jobs competing for resources and some jobs are more critical than others
Setting job priorities and classes becomes crucial in a scenario where multiple jobs compete for system resources. By assigning higher priorities to critical jobs, you ensure they get preferential treatment in resource allocation, leading to efficient job execution.
