z/Architecture - Memory, Address Spaces, and Virtual Storage

Duration

3 hours

Overview

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.
