This IBM Redbooks publication addresses some of the common problems that customers have experienced on the Linux® on System zTM platform. This book provides a problem determination methodology and tools to help the reader diagnose the problem in an easy-to-read self-help manual. We start with a discussion on how to approach problem solving in the Linux on System z environment and continue on to describe some of the problem determination tools commonly used for z/VM and Linux on system z. We continue with discussions on network problem determination, performance problem determination, and storage problems. Additionally, we discuss the formation of eligible (or eligibility) lists.

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.

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.

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.

In a smarter planet, information-centric processes are exploding in growth. The mainframe has always been the IT industry's leading platform for transaction processing, consolidated and secure data serving, and support for available enterprise-wide applications. IBM® has extended the mainframe platform to help large enterprises reshape their client experiences through information-centric computing and to deliver on key business initiatives. IBM zEnterprise® is recognized as the most reliable and trusted system, and the most secure environment for core business operations. The new zEnterprise System consists of the IBM zEnterprise EC12 (zEC12) or IBM zEnterprise BC12 (zBC12), the IBM zEnterprise Unified Resource Manager, and the IBM zEnterprise IBM BladeCenter® Extension (zBX) Model 003. This IBM Redbooks® publication describes the zEC12 and zBC12, with their improved scalability, performance, security, resiliency, availability, and virtualization. The zEnterprise System has no peer as a trusted platform that also provides the most efficient transaction processing and database management. With efficiency at scale delivering significant cost savings on core processes, resources can be freed up to focus on developing new services to drive growth. This book provides a technical overview of the zEC12, zBC12, zBX Model 003, and Unified Resource Manager. This publication is intended for IT managers, architects, consultants, and anyone else who wants to understand the elements of the zEnterprise System. For this introduction to the zEnterprise System, readers are not expected to be familiar with current IBM System z® technology and terminology.
