For more than 40 years, IBM® mainframes have supported an extraordinary portion of the world's computing work, providing centralized corporate databases and mission-critical enterprise-wide applications. The IBM System z®, the latest generation of the IBM distinguished family of mainframe systems, has come a long way from its IBM System/360 heritage. Likewise, its IBM z/OS® operating system is far superior to its predecessors, providing, among many other capabilities, world-class, state-of-the-art, support for the TCP/IP Internet protocol suite.
TCP/IP is a large and evolving collection of communication protocols managed by the Internet Engineering Task Force (IETF), an open, volunteer, organization. Because of its openness, the TCP/IP protocol suite has become the foundation for the set of technologies that form the basis of the Internet. The convergence of IBM mainframe capabilities with Internet technology, connectivity, and standards (particularly TCP/IP) is dramatically changing the face of information technology and driving requirements for ever more secure, scalable, and highly available mainframe TCP/IP implementations.
The IBM z/OS Communications Server TCP/IP Implementation series provides understandable, step-by-step guidance about how to enable the most commonly used and important functions of z/OS Communications Server TCP/IP. This IBM Redbooks® publication explains how to set up security for your z/OS networking environment. With the advent of TCP/IP and the Internet, network security requirements have become more stringent and complex. Because many transactions come from unknown users and from untrusted networks such as the Internet, careful attention must be given to host and user authentication, data privacy, data origin authentication, and data integrity. Also, because security technologies are complex and can be confusing, we include helpful tutorial information in the appendixes of this book.
For more specific information about z/OS Communications Server base functions, standard applications, and high availability, refer to the other volumes in the series:
"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 1: Base Functions, Connectivity, and Routing," SG24-7798
"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 2: Standard Applications," SG24-7799
"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 3: High Availability, Scalability, and Performance," SG24-7800
In addition, "z/OS Communications Server: IP Configuration Guide," SC31-8775, "z/OS Communications Server: IP Configuration Reference," SC31-8776, and "z/OS Communications Server: IP User's Guide and Commands," SC31-8780, contain comprehensive descriptions of the individual parameters for setting up and using the functions that we describe in this book. They also include step-by-step checklists and supporting examples.
It is not the intent of this book to duplicate the information in those publications, but to complement them with practical implementation scenarios that might be useful in your environment. To determine at what level a specific function was introduced, refer to "z/OS Communications Server: New Function Summary," GC31-8771.

The Virtualization Cookbook for IBM z Systems Volume 2: Red Hat Enterprise Linux Server 7.1, SG24-8303
The Virtualization Cookbook for IBM z Systems Volume 3: SUSE Linux Enterprise Server 12, SG24-8890
It is recommended that you start with Volume 1 of this series because IBM z/VM® is the base "layer" when you install Linux on z Systems. Volume 1 starts with an introduction, discusses planning, then describes z/VM installation into a two-node single system image (SSI) cluster, configuration, hardening, automation, and servicing. It adopts a cookbook format that provides a concise, repeatable set of procedures for installing and configuring z/VM by using the z/VM SSI clustering feature.
Volume 1 consists of the following chapters:
Chapter 1, "Introduction to Linux on the IBM mainframe under z/VM" on page 3. This chapter provides a concise introduction to the concept of using the z/VM platform as an enterprise Linux infrastructure on the IBM mainframe.
Chapter 2, "Planning" on page 15. This chapter covers the planning of hardware, software, and networking resources that you need to do before you attempt to install z/VM and Linux.
Chapter 3, "Configuring a workstation for mainframe access" on page 39. This chapter addresses the configuration of a workstation that is running either Linux or Windows to access the mainframe.
Chapter 4, "Installing and configuring z/VM" on page 49. This chapter describes installing z/VM 6.3 as a two-node VM Single System Image feature (VMSSI) cluster, performing the initial configuration, hardening, and enabling basic system automation.
Chapter 5, "Servicing z/VM" on page 153. This chapter focuses on the requirements to keep your z/VM systems updated to ensure full functionality, optimal utility, security, and the elimination of known problems. The process of ordering and applying z/VM Service is described. Programming Temporary Fixes (PTFs) and Recommended Service Upgrades (RSUs) are both covered.
Chapter 6, "Planning and preparing for Linux workloads" on page 171. This chapter describes the necessary steps to begin your first Linux installation. It describes common tasks that are executed during administration, maintenance, and expansion to accommodate additional workloads.
Volumes 2 and 3 describe how to Linux virtual servers on IBM z SystemsTM hardware under IBM z/VM. The cookbook format continues with installing and customizing Linux.
For Volume 1, you need at least two IBM z Systems logical partitions (LPARs) with associated resources and z/VM 6.3 installation media. For Volumes 2 and 3, you will need either the Red Hat Enterprise Linux Server (RHEL) version 7.1 or the SUSE Linux Enterprise Server (SLES) version 12 distribution (or both).
This book series assumes that you are generally familiar with z Systems technology and terminology. It does not assume an in-depth understanding of z/VM or Linux. It is written for those individuals who want to start quickly with z/VM and Linux on the mainframe, and get virtual servers up and running in a short time (days, not weeks or months).
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.
The IBM® Storwize® family, including the IBM SAN Volume Controller Data Platform, is a storage virtualization system that enables a single point of control for storage resources. This functionality helps support improved business application availability and greater resource use. The following list describes the business objectives of this system:
To manage storage resources in your information technology (IT) infrastructure
To make sure that those resources are used to the advantage of your business
To do it quickly, efficiently, and in real time, while avoiding increases in administrative costs
Virtualizing storage with Storwize helps make new and existing storage more effective. Storwize includes many functions traditionally deployed separately in disk systems. By including these functions in a virtualization system, Storwize standardizes them across virtualized storage for greater flexibility and potentially lower costs.
Storwize functions benefit all virtualized storage. For example, IBM Easy Tier® optimizes use of flash memory. In addition, IBM Real-time CompressionTM enhances efficiency even further by enabling the storage of up to five times as much active primary data in the same physical disk space. Finally, high-performance thin provisioning helps automate provisioning. These benefits can help extend the useful life of existing storage assets, reducing costs.
Integrating these functions into Storwize also means that they are designed to operate smoothly together, reducing management effort.
This IBM Redbooks® publication provides information about the latest features and functions of the Storwize V7000 Gen2 and software version 7.3 implementation, architectural improvements, and Easy Tier.
This edition includes information about the Virtual Storage Console (VSC), which is another N series software product that works with VMware. VSC provides local backup and recovery capability. You have the option to replicate backups to a remote storage system by using SnapMirror relationships. Backups can be performed on individual virtual machines or on datastores with the option of updating the SnapMirror relationship as part of the backup on a per job basis. Similarly, restores can be performed at a data-store level or individual virtual machine level.
IBM System Storage N series in conjunction with VMware vSphere 4 helps complete the virtualization hierarchy by providing both a server and storage virtualization solution. Although this configuration can further assist with other areas of virtualization, networks, and applications, these areas of virtualization are not covered in detail in this book.
We start with a general overview of virtualization and describe specific server virtualization technologies to highlight how the server virtualization technologies have been implemented. With this introduction anyone new to virtualization will have a better understanding of server virtualization and the industry server virtualization technologies available in the market.
Following the virtualization concept, we describe in detail the setup, configuration, and managing of DB2 with three leading server virtualization technologies:
IBM Power SystemsTM with PowerVMTM
We discuss the virtual machine setup with DB2 in mind to help IT support understand the effective ways of setting up a virtual environment specific for DB2. We explain the architecture and components of these three server virtualization technologies to allow DBAs to understand how a database environment using DB2 can benefit from using the server virtualization technologies.
In addition, we discuss the DB2 features and functions that can take advantage of using server virtualization. These features are put into practice when describing how to set up DB2 with the three virtualization technologies discussed in this book. This book also includes a list of best practices from the various tests performed while using these virtualization technologies. These best practices can be used as a guideline or a reference when setting up DB2 using these virtualization technologies.
This paper supplements the IBM Tivoli Access Manager for Enterprise Single Sign-On 8.1 Installation Guide and IBM Tivoli Access Manager for Enterprise Single Sign-On 8.1 Setup Guide. Do not use this document in isolation. Check the relevant guides in the Tivoli Access Manager for Enterprise Single Sign-On Information Center as you perform the install.
There might be various reasons to install Tivoli Access Manager for Enterprise Single Sign-On into either a single server or a clustered environment. A small-scale deployment, a typical proof of technology, or a proof of concept might be the best examples for a single server installation, whereas larger scale deployments or requirements for high availability and scalability might be reasons to deploy in a clustered environment.
This IBM Redpaper is targeted towards administrators and engineers who are facing a Tivoli Access Manager for Enterprise Single Sign-On deployment on either a single IBM WebSphere Application Server or a clustered IBM WebSphere Application Server Network Deployment configuration.

This IBM Redbooks® publication addresses the new IBM zEnterprise® System. This system consists of the IBM zEnterprise EC12 (zEC12), an updated IBM zEnterprise Unified Resource Manager, and the IBM zEnterprise BladeCenter® Extension (zBX) Model 003.
The zEC12 is designed with improved scalability, performance, security, resiliency, availability, and virtualization. The superscalar design allows the zEC12 to deliver a record level of capacity over the prior System z servers. It is powered by 120 of the world's most powerful microprocessors. These microprocessors run at 5.5 GHz and are capable of running more than 75,000 millions of instructions per second (MIPS). The zEC12 Model HA1 is estimated to provide up to 50% more total system capacity than the IBM zEnterprise 196 (z196) Model M80.
The zBX Model 003 infrastructure works with the zEC12 to enhance System z virtualization and management. It does so through an integrated hardware platform that spans mainframe, IBM POWER7®, and IBM System x® technologies. Through the Unified Resource Manager, the zEnterprise System is managed as a single pool of resources, integrating system and workload management across the environment.
This book provides information about the zEnterprise System and its functions, features, and associated software support. Greater detail is offered in areas relevant to technical planning. It is intended for systems engineers, consultants, planners, and anyone who wants to understand the zEnterprise System functions and plan for their usage. It is not intended as an introduction to mainframes. Readers are expected to be generally familiar with existing IBM System z® technology and terminology.
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.
The target audience for this book is IT developers, IT managers, IT architects, project managers, test managers, test developers, operations managers, and operations developers.
