C. status of expanded storage
D. none
Answer
B. status of central storage
Explanation
The z/OS command “D M=STOR” displays the status of central storage on a mainframe system. When executed, this command provides a real-time snapshot of the current state of the main memory, also known as central storage.
Central storage is the primary memory in a mainframe system where the operating system, application programs, and data reside for quick access by the CPU during processing. It is a critical component of the system, and monitoring its status is essential for ensuring optimal performance and identifying potential issues.
When you enter “D M=STOR” in the z/OS command line, the system generates a report that includes information such as:
- Total amount of central storage available
- Amount of central storage currently in use
- Amount of central storage currently free
- Percentage of central storage utilization
This command does not display the status of all CPUs, expanded storage, or any other components. Its sole purpose is to provide information about the central storage status.
In summary, the z/OS command “D M=STOR” is a valuable tool for mainframe system administrators and operators to quickly assess the status of central storage, helping them monitor system performance and make informed decisions about resource allocation.
