Book Description
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.

Book Description
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.

Book Description
As business cycles speed up, many customers gain significant competitive advantage from quicker and more accurate business decision-making by using real data. For many customers, choosing the path to co-locate their transactional and analytical workloads on System z® better leverages their existing investment in hardware, software, and skills. We created a project to address a number of best practice questions on how to manage these newer, analytical type workloads, especially when co-located with traditional transactional workloads. The goal of this IBM® Redbooks® publication is to provide technical guidance and performance trade-offs associated with resource management and potentially DB2® data-sharing in a variety of mixed transactional / data warehouse System z topologies. The term co-location used here and in the rest of the book is specifically defined as the practice of housing both transactional (OLTP) and data warehouse (analytical) workloads within the same System z configuration. We also assumed that key portions of the transactional and data warehouse databases would reside on DB2 for z/OS®. The databases may or may not reside in a DB2 data-sharing environment; we discuss those pros and cons in this book. The intended audience includes DB2 data warehouse architects and practitioners who are facing choices in resource management and system topologies in the data warehouse arena. This specifically includes Business Intelligence (BI) administrators, DB2 database administrators (DBAs) and z/OS performance administrators / systems programmers. In addition, decision makers and architects can utilize this book to assist in making platform and database topology decisions. The book is divided into four parts. Part I, "Introducing the co-location project" covers the System z value proposition and why one should consider System z as the central platform for their data warehousing / business analytics needs. Some topics are risk avoidance via data consolidation, continuous availability, simplified disaster recovery, IBM Smart Analytics Optimizer, reduced network bandwidth requirements, and the unique virtualization and resource management capabilities of System z LPAR, z/VM® and WLM. Part I also provides some of the common System z co-location topologies along with an explanation of the general pros and cons of each. This would be useful input for an architect to understand where a customer is today and where they might consider moving to. Part II, "Project environment" covers the environment, products, workloads, workload drivers, and data models implemented for this study. The environment consisted of a logically partitioned z10TM 32way, running z/VM, Linux®, and z/OS operating system instances. On those instances we ran products such as z/OS DB2 V9, IBM Cognos® Business Intelligence Version 8.4 for Linux on System z, InfoSphereTM Warehouse for System z, InfoSphere Change Data Capture, z/OS WebSphere® V7, Tivoli® Omegamon for DB2 Performance expert. Utilizing these products we created transactional (OLTP), data warehouse query, and data warehouse refresh workloads. All the workloads were based on an existing web-based transactional Bookstore workload, that's currently utilized for internal testing within the System p® and z labs. While some IBM Cognos BI and ISWz product usage and experiences information is covered in this book, we do not go into the depth typically found in IBM Redbooks publications, since there's another book focused specifically on that

Book Description
Data is one the most critical and valuable assets of a business. Critical strategic decisions can be made more quickly and effectively when they are based on complete, accurate, and timely operational data. From this point of view, it is important to have an enterprise data management architecture that supports a flexible global view of the business. Many environments today are heterogeneous with a high quantity and diversity of data. In this IBM® Redbooks® publication, we help enterprise architects and IT managers with these environments make decisions for a centralized database or data warehouse. We recommend a centralized data management environment on Linux® on System z®. We include guidance for IBM z/VSETM and Linux specialists to reorganize existing IBM DB2® VSE data and build a database environment with continuous operation in Linux on System z. We begin this book by describing the possibilities and advantages of enterprise data management and different technical ways to realize it. Then we discuss planning, which is important for setting the foundation of the architecture that is implemented. We explain the hardware considerations for capacity and performance planning. For the z/VSE system and Linux on System z, we describe considerations for operation in a logical partition (LPAR) and in a virtualized environment with IBM z/VM®. In addition, we discuss the disk behavior for different workloads, storage dependencies, network connections, and DB2 database considerations. We also guide you in customizing the DB2 server for z/VSE, z/VM, and DB2 on Linux to allow existing z/VSE and z/VM applications to access the database on Linux on System z. We include the data migration, application considerations, dependencies, compatibility, monitoring, and tuning possibilities in such an environment.

Book Description
IBM WebSphere Application Server for z/OS V6 is a complex product made up of many components. This IBM Redbooks publication focuses on the problems that you can experience with WebSphere for z/OS. It is intended for system programmers and administrators who need to identify, analyze, and fix problems efficiently so that they can deliver good support for the WebSphere environment. In Part 1, we provide an overview of problem determination methodology, what skills you need, where to find information about related topics, and how to communicate with IBM when a problem occurs. In Part 2, we describe the most common problem symptoms. Flow charts guide you through the problem analysis process step by step. Individual tasks and questions help you filter out irrelevant facts and find the problem area, so that you can identify the type, source, cause, and possibly a solution. In Part 3, we identify possible problem areas and arrange them into four phases that correspond with WebSphere for z/OS life cycle stages. We explain how to analyze the problems and provide valuable hints and tips for avoiding them. In Part 4, we provide means and tools for problem determination such as commands, logs, dumps, traces, and diagnostic tools. We describe other tools that can ease the day-to-day tasks and prevent problems. We also explain where to get these tools, show you how to use them, and provide examples. Please note that the additional material referenced in the text is not available from IBM.
