IBM® z/VM® 6.2 introduced significant changes to z/VM with a multi-system clustering technology that allows up to four z/VM instances in a single system image (SSI) cluster. This technology is important because it offers you an attractive alternative to vertical growth by adding new z/VM systems. In the past, this capability required duplicate efforts to install, maintain, and manage each system. With SSI, these duplicate efforts are reduced or eliminated. Support for live guest relocation (LGR) allows you to move Linux virtual servers without disrupting your business or incurring loss of service, thus reducing planned outages. The z/VM systems are aware of each other and take advantage of their combined resources. LGR enables you to relocate guests from a system requiring maintenance to a system that will remain active during maintenance. A major advantage for DB2 v10 customers is that using z/VM 6.2 does not require any changes to existing DB2 structures. This remarkable benefit is due to the fact that DB2 v10 is installed as part of the LInux guest on z/VM and is fully integrated into LGR. This allows you to smoothly move DB2 v10 when you move Linux virtual servers, without interrupting either DB2 v10 or z/VM operations and services. This IBM Redbooks® publication will help you understand how DB2 10 on Linux for System z® behaves while running on a z/VM that is being relocated using z/VM's 6.2 Live Guest Relocation feature. In this book, we explore memory management, the DB2 Self-tuning memory manager feature, time synchronization, networking, and storage and performance considerations with regards to relocation. We also offer some best practices found during a live guest relocation for DB2 v10.

In this IBM® Redbooks® publication, we expand upon the concepts and experiences described in "An introduction to z/VM Single System Image (SSI) and Live Guest Relocation (LGR)", SG24-8006. An overview of that book is provided in Chapter 1, "Overview of SSI and LGR" on page 1. In writing this book, we re-used the same lab environment used in the first book, but expanded it to include IBM DB2® v10 on Linux on System z®, two IBM WebSphere® Application Server environments, and added a WebSphere application, used for performance benchmarking, which provided a workload that allowed us to observe the performance of the WebSphere Application Server during relocation of the z/VM® 6.2 member that was hosting the application server. Additionally, this book examines the use of small computer system interface (SCSI) disks in the z/VM v6.2 environment and the results of using single system images (SSI) and live guest relocation (LGR) in this type of environment. In the previous book, a detailed explanation of relocation domains was provided. In this book, we expand that discussion and provide use cases of relocation domains in different situations. Finally, because the ability to back up and restore your data is of paramount importance, we have provided a discussion about how to use one tool, the IBM Backup and Restore Manager for z/VM, which can be used in the new z/VM6.2 environment. We provide a brief overview of the tool and describe the changes in the installation process as a result of using single system image clusters. We also demonstrate how to set up the configuration file, and how to back up and restore both a user and an identity. This publication is intended for IT architects who will be responsible for designing the system and IT specialists who will have to build the system.

LinuxONE is a portfolio of hardware, software, and solutions for an enterprise-grade Linux environment. It has been designed to run more transactions faster and with more security and reliability specifically for the open community. It fully embraces open source-based technology. Two servers are available for LinuxONE: The IBM® LinuxONE III LT1 and IBM LinuxONE III LT2. We describe these servers in "IBM LinuxONE servers" on page 5. Aside from still running SUSE Linux Enterprise Server and Red Hat Enterprise Linux Servers, LinuxONE runs Ubuntu, which is popular on x86 hardware. Ubuntu, which runs the cloud, smartphones, a computer that can remote control a planetary rover for NASA, many market-leading companies, and the Internet of Things, is now available on IBM LinuxONE servers. Together, these two technology communities deliver the perfect environment for cloud and DevOps. Ubuntu 16.04 on LinuxONE offers developers, enterprises, and Cloud Service Providers a scalable and secure platform for next generation applications that include OpenStack, KVM, Docker, and JuJu. The following are reasons why you would want to optimize your servers through virtualization using LinuxONE: Too many distributed physical servers with low utilization A lengthy provisioning process that delays the implementation of new applications Limitations in data center power and floor space High total cost of ownership (TCO) Difficulty allocating processing power for a dynamic environment This IBM Redbooks® publication provides a technical planning reference for IT organizations that are considering a migration from their x86 distributed servers to LinuxONE. This book walks you through some of the important considerations and planning issues that you might encounter during a migration project. Within the context of a pre-existing UNIX based or x86 environment, it presents an end-to-end view of the technical challenges and methods necessary to complete a successful migration to LinuxONE.

This IBM® Redbooks® publication shows the power of IBM System z® virtualization and flexibility in sharing resources in a flexible production environment. In this book, we outline the planning and setup of Linux on System z to move from a development or test environment into production. As an example, we use one logical partition (LPAR) with shared CPUs with memory for a production environment and another LPAR that shares some CPUs, but also has a dedicated one for production. Running in IBM z/VM® mode allows for virtualization of servers and based on z/VM shares, can prioritize and control their resources. The size of the LPAR or z/VM resources depends on the workload and the applications that run that workload. We examine a typical web server environment, Java applications, and describe it by using a database management system, such as IBM DB2®. Network decisions are examined with regards to VSWITCH, shared Open Systems Adapter (OSA), IBM HiperSocketsTM and the HiperPAV, or FCP/SCSI attachment used with a storage area network (SAN) Volume Controller along with performance and throughput expectations. The intended audience for this IBM Redbooks publication is IT architects who are responsible for planning production environments and IT specialists who are responsible for implementation of production environments.

IBM® z/VM® 6.2 introduces significant changes to z/VM in the form of multi-system clustering technology allowing up to four z/VM instances in a single system image (SSI) cluster. This technology is important, because it offers clients an attractive alternative to vertical growth by adding new z/VM systems. In the past, this capability required duplicate efforts to install, maintain, and manage each system. With SSI, these duplicate efforts are reduced or eliminated. Support for live guest relocation (LGR) allows you to move Linux virtual servers without disruption to the business, helping you to avoid planned outages. The z/VM systems are aware of each other and can take advantage of their combined resources. LGR enables clients to avoid loss of service due to planned outages by relocating guests from a system requiring maintenance to a system that remains active during the maintenance period. Together, the SSI and LGR technologies offer substantial client value, and they are a major departure from past z/VM practices. This IBM Redbooks® publication gives you a broad understanding of the new SSI architecture and an overview of LGR. We show an LGR example that shows a typical SAP user environment. In our example, the SAP Application Server Central Instance resides on a Linux on System z® guest and an IBM DB2® 10 database server runs on z/OS®. This book is written for IT architects, who design the systems, and IT specialists, who build the systems.

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 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.
