This IBM® Redbooks® publication provides advice and guidance for IBM z/OS® Version 1, Release 10 and subsystem system programmers. z/OS is an IBM flagship operating system for enterprise class applications, particularly those with high availability requirements. But, as with every operating system, z/OS requires planned IPLs from time to time. This book also provides you with easily accessible and usable information about ways to improve your mean time to recovery (MTTR) by helping you achieve the following objectives: - Minimize the application down time that might be associated with planned system outages. - Identify the most effective way to reduce MTTR for any time that you have a system IPL. - Identify factors that are under your control and that can make a worthwhile difference to the startup or shutdown time of your systems.

This IBM® Redbooks® publication will help you design and manage an end-to-end, extended distance connectivity architecture for IBM System z®. This solution addresses your requirements now, and positions you to make effective use of new technologies in the future. Many enterprises implement extended distance connectivity in a silo manner. However, effective extended distance solutions require the involvement of different teams within an organization. Typically there is a network group, a storage group, a systems group, and possibly other teams. The intent of this publication is to help you design and manage a solution that will provide for all of your System z extended distance needs in the most effective and flexible way possible. This book introduces an approach to help plan, optimize, and maintain all of the moving parts of the solution together.

This IBM Redbooks publication provides information to help Systems Programmers plan for merging systems into a sysplex. zSeries systems are highly flexibile systems capable of processing many workloads. As a result, there are many things to consider when merging independent systems into the more closely integrated environment of a sysplex. This book will help you identify these issues in advance and thereby ensure a successful project.

This IBM® Redbooks® publication explains the capabilities of the IBM System z® Advanced Workload Analysis Reporter (IBM zAware), and shows how you can use it as an integral part of your existing System z management tools. IBM zAware is an integrated, self-learning, analytics solution for IBM z/OS® that helps identify unusual system behavior in near real time. It is designed to help IT personnel improve problem determination so they can restore service quickly and improve overall availability. The book gives you a conceptual description of the IBM zAware appliance. It will help you to understand how it fits into the family of IBM mainframe system management tools that include Runtime Diagnostics, Predictive Failure Analysis (PFA), IBM Health Checker for z/OS, and z/OS Management Facility (z/OSMF). You are provided with the information you need to get IBM zAware up and running so you can start to benefit from its capabilities immediately. You will learn how to manage an IBM zAware environment, and see how other products can use the IBM zAware Application Programming Interface to extract information from IBM zAware for their own use. The target audience includes system programmers, system operators, configuration planners, and system automation analysts.

This IBM® Redbooks® publication is intended to make System Programmers, Operators, and Availability Managers aware of the enhancements to recent releases of IBM z/OS® and its major subsystems in the area of planned outage avoidance. It is a follow-on to, rather than a replacement for, z/OS Planned Outage Avoidance Checklist, SG24-7328. Its primary objective is to bring together in one place information that is already available, but widely dispersed. It also presents a different perspective on planned outage avoidance. Most businesses care about application availability rather than the availability of a specific system. Also, a planned outage is not necessarily a bad thing, if it does not affect application availability. In fact, running for too long without an IPL or subsystem restart might have a negative impact on application availability because it impacts your ability to apply preventive service. Therefore, this book places more focus on decoupling the ability to make changes and updates to your system from IPLing or restarting your systems.
