Introduction to the new mainframe © Copyright IBM Corp., All rights reserved. 2 Chapter objectives After completing this chapter, you will be able to: Understand autonomic computing capabilities Understand the autonomic computing framework Know the autonomic capabilities of large-scale commercial systems Know the autonomic computing tool

Introduction to the new mainframe © Copyright IBM Corp., All rights reserved. 3 Autonomic Computing Principles The self-configuring, self-healing, self-optimizing, and self-protecting technologies of operating environments and systems. Anticipate, detect, identify and protect against attacks Seamless integration and distribution of resources by the operating system Instant detection, diagnosis and reaction to system disruptions Automatically measure and tune resources to improve performance and usage Self- Configuring Self- Healing Self- Optimizing Self- Protecting

Capacity upgrade CPU provides instant access to additional processors or servers, memory, I/O. Customer-initiated upgrade. Automatic hardware detection/configuration. Automatic communication configuration.
