Abstract
Resiliency is the ability to provide the required capability in the face of adversity, without significant impact. This is not something that just happens, but rather must be thoroughly planned for and tested, including:
- Keeping hardware, the operating system, middleware, and applications up and running throughout planned and unplanned outages
- Recovering a site from an unplanned event without data loss
This IBM Redbooks publication gives a broad understanding of resiliency on the IBM Z platform and explains how it works and why it is important. It describes the technology and built-in resiliency capabilities of the IBM Z platform at various hardware and software levels, and discusses what to consider when pursuing higher availability.
This publication is intended for IT managers, IT architects, system programmers, and system operations professionals.
