Tags: Proceedings , SHARE Virtual Experience 2021

The flexibility to reassign (add and remove) system resources is critical to customers. Today's workloads are not static. With Dynamic Memory Downgrade, a system administrator can take real memory offline from a z/VM partition, making it available to other partitions on the CPC. The removal will be dynamic; no reIPL of the z/VM image is required to accomplish a change in the memory configuration. This session will describe these new capabilities, give some guidance on use, and walk through some examples.
