Question
Which controls the access of the work to the system processors
A. Workload manager
B. Workload partition
C. Both A & B
D. None of the above
Answer
A. Workload manager
Explanation
In mainframe systems, the workload manager is responsible for controlling the access of work to the system processors. It prioritizes and schedules work based on predefined goals and policies to ensure optimal performance and resource utilization.
The workload manager dynamically adjusts priorities and resource allocation as the workload and system conditions change. It takes into account factors such as job importance, resource requirements, and service level agreements to make intelligent decisions about which tasks get access to the processors and in what order.
On the other hand, workload partitions are used to logically divide a mainframe’s processing capacity into separate virtual machines. Each partition can run its own operating system and applications independently. However, the workload partitions themselves do not control access to the processors. That is the job of the workload manager, which operates at a higher level and manages the work across all partitions.
In summary, while both workload managers and workload partitions play important roles in mainframe systems, it is the workload manager that specifically controls the access of work to the system processors.
