Processor storage, real storage, or central storage. Whatever you call it, it is the memory where z/OS programs and their data need to reside before they can be processed, and like other mainframe resources it can be virtualized. In this z/OS Architecture - Memory, Address Spaces and Virtual Storage course, you will see how the address spaces discussed in the previous course, access and free the memory they require to process work. You will also see how virtualization of this resource occurs, which for IT specialists will provide them with knowledge to troubleshoot memory-related issues.
Operations, Systems Programmers, and technical support personnel requiring in-depth knowledge about memory utilization in a z/OS environment.
Completion of Interskill's z/Architecture - Processing Workloads course, or equivalent knowledge.
After completing this course, the student will be able to describe how:
- Memory is configured and used within a z/OS environment
- z/OS manages virtual storage
