This book was released on 2014-12-22 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2014-10-30 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Linux on System z becomes more prevalent and mainstream in the industry, the need for it to deliver higher levels of availability is increasing. This IBM Redbooks publication starts with an explanation of high availability (HA) fundamentals such as HA concepts and terminology. It continues with a discussion of why a business needs to consider an HA solution and then explains how to determine your business single points of failure. We outline the components of a high availability solution and describe these components. Then we provide some architectural scenarios and demonstrate how to plan and decide an implementation of an end-to-end HA solution, from Linux on System z database scenarios to z/OS, and include storage, network, z/VM, Linux, and middleware. This implementation includes the IBM Tivoli System Automation for Multiplatforms (TSA MP), which monitors and automates applications distributed across Linux, AIX®, and z/OS® operating systems, as well as a GDPS based solution. It includes the planning for an end-to-end scenario, considering Linux on System z, z/VM, and z/OS operating environments, and the middleware used. The TSA MP implements HA for infrastructure, network, operating systems, and applications across multiple platforms and is compared to a Linux HA implementation based on open source Linux-HA, which is Linux only.

This book was released on 2015-09-25 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication documents the strength and value of the IBM security strategy with IBM z Systems hardware and software (referred to in this book by the previous product name, IBM System z®). In an age of increasing security consciousness and more dangerous and advanced persistent threats, System z provides the capabilities to address today's business security challenges. This book explores how System z hardware is designed to provide integrity, process isolation, and cryptographic capability to help address security requirements. We highlight the features of IBM z/OS® and other operating systems that offer a variety of customizable security elements. We also describe z/OS and other operating systems and additional software that use the building blocks of System z hardware to meet business security needs. We explore these from the perspective of an enterprise security architect and how a modern mainframe must fit into an enterprise security architecture. This book is part of a three-volume series that focuses on guiding principles for optimized mainframe security configuration within a holistic enterprise security architecture. The intended audience includes enterprise security architects, planners, and managers who are interested in exploring how the security design and features of the System z platform, the z/OS operating system, and associated software address current issues, such as data encryption, authentication, authorization, network security, auditing, ease of security administration, and monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: Is it time for you to modernize your IBM® z/OS® applications to allow for access to an entire system of open source and Linux on IBM Z® workloads? Is co-location of these workloads on the z/OS platform with no porting requirements of value to you? Your open source or Linux on IBM Z software can benefit from being co-located and managed inside a z/OS environment; leveraging z/OS quality of service for optimized business continuity. Your software can be integrated with and can help complement existing z/OS workloads and environments. If your software can communicate with z/OS and external components by using TCP/IP, now is the time examine how IBM z/OS Container Extensions (IBM zCX) makes it possible to integrate Linux on Z applications with z/OS. This IBM Redbooks® publication is a follow-on to Getting started with z/OS Container Extensions and Docker, SG24-8457, which provides some interesting use cases for zCX. We start with a brief overview of IBM zCX. In Part 1, "Integration" on page 9, we demonstrate use cases that integrate with zCX. In Part 2, "DevOps in zCX" on page 165, we describe how organizations can benefit from running a DevOps flow in zCX and we describe the set up of necessary components. Finally, in Part 3, "Monitoring and managing zCX systems" on page 229, we discuss IBM Service Management Unite Automation, a free-of-charge customizable dashboard interface and an important discussion of creating the suitable container restart policy.

Available in PDF, EPUB and Kindle. Book excerpt: IBM® Geographically Dispersed Parallel SysplexTM (GDPS®) is a collection of several offerings, each addressing a different set of IT resiliency goals. It can be tailored to meet the recovery point objective (RPO), which is how much data can you are willing to lose or recreate, and the recovery time objective (RTO), which identifies how long can you afford to be without your systems for your business from the initial outage to having your critical business processes available to users. Each offering uses a combination of server and storage hardware or software-based replication, and automation and clustering software technologies. This IBM Redbooks® publication presents an overview of the IBM GDPS active/active (GDPS/AA) offering and the role it plays in delivering a business IT resilience solution.

This book was released on 2011-10-14 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: You may have several triggers to investigate the feasibility of moving a workload or set of workloads to the IBM® System z® platform. These triggers could be concerns about operational cost, manageability, or delivering the agreed service levels, among others. Investigating the feasibility of a possible migration or transition to any other platform, including System z, requires a number of basic steps. These steps usually start with an understanding of the current workload and its pain points, and end with a business case to move the workload. It is important to find out how easy a migration is going to be and how much risk will be involved. In this IBM Redbooks® publication we offer thoughts on how to move through these steps. We also include a chapter with a System z technology summary to help you understand how a migrated workload may fit on the platform. Our focus in this book is on workloads that are mission-critical and require a high level of availability, including disaster recovery.
