Über dieses Buch

"Running Mainframe z on Distributed Platforms is particularly suitable for a more detailed discussion." Bill Ogden, IBM zPDT Redbook, April 2015

"The authors offer very well-reasoned solutions accompanied by case studies, which will be useful to specialists. The book is made even more useful as the System z mainframe-based solutions offer an advanced systems management environment for significant segments of data within large companies." Eugen Petac, Computing Reviews, Oct. 8, 2014

"Should you choose to implement zPDT, RDz UT, or RD&T in your team's arsenal, you will find Barrett and Norris’s insights, genius, and hard work illuminating as to how to rationally and economically manage the environment." —Scott Fagen, Chief Architect—System z Business, CA Technologies

"A must-read for anyone interested in successfully deploying cost-efficient zPDT environments with agility in an enterprise that requires simple or complex configurations. The case-study-based exposition of the content allows for its easy consumption and use. Excellent!" —Mahendra Durai, SVP & Information Technology Officer, CA

Running Mainframe z on Distributed Platforms reveals alternative techniques not covered by IBM for creatively adapting and enhancing multi-user IBM zPDT environments so that they are more friendly, stable, and reusable than those envisaged by IBM. The enhancement processes and methodologies taught in this book yield multiple layers for system recovery, 24x7 availability, and superior ease of updating and upgrading operating systems and subsystems without having to rebuild environments from scratch.

Most of the techniques and processes covered in this book are not new to either the mainframe or distributed platforms. What is new in this book are the authors’ innovative methods for taking distributed environments running mainframe virtual machine (VM) and multiple virtual storage (MVS) and making them look and feel like other MVS systems.

The authors’ combined expertise involves every aspect of the implementation of IBM zPDT technology to create virtualized mainframe environments by which the mainframe operations on a z series server can be transitioned to distributed platforms. All of the enhancement methods consecutively laid out in this book have been architected and developed by the authors for the CA Technologies distributed platform. Barrett and Norris impart these techniques and processes to CIOs and CTOs across the mainframe and distributed fields, to zPDT and RDz UT implementers, and to IBM’s independent software vendors and customers.

Chapter 1. Understanding the Mainframe Environment, Technologies, and Methodologies
Abstract
This chapter provides a cursory review of the aspects of mainframe technology that are commonly practiced and implemented on the zPDT environment. It serves to orient readers toward the in-depth information on mainframe and distributed technologies we present in the subsequent chapters. Although we assume that most of our readers have prior knowledge of mainframe technologies, we couch our descriptions of it so that non-mainframers and even novices can follow along.

Chapter 2. Creating a Mainframe Virtualized Environment: Requirements and Choices
Abstract
Several factors that drive the configuration of the mainframe virtualized environment need to be taken into account when you define the requirements for virtualized systems. The most salient requirement is the use case—the objective that is to be achieved by utilizing the virtual systems. Once you define the use case, you can finalize the other requirements. These include access to the systems, the number of systems, hardware specifications, and data sharing.

Chapter 3. Building the Hypervisor Host
Abstract
Once the use case and requirements for your virtualized system environment have been specified (Chapter 2), you have to design the networking scheme, implement the storage configuration, and install and configure the Linux operating system.
Kenneth/Stephen Barrett/Norris
Chapter 4. Creating a Base Environment
Abstract
Creating a basic virtualized mainframe environment is dependent on the mainframe architecture required. There are several schemes that can be employed. The first is a simple, single system configuration. This configuration can be expanded to include two or more systems running independently. Another, more complex virtual environment consists of a first level z/VM host and one or more guest systems. Any combination of these configurations can be utilized depending on the use case for the virtual environment. Regardless of which architecture is desired, the procedure for creating the environment is the same:

Chapter 5. Constructing the z/VM Environment
Abstract
While simple use cases can be satisfied with a single virtual system, more complicated use cases will require an environment consisting of multiple virtual systems. Here are several methods for providing multiple virtual systems, with their pros and cons:

Chapter 6. Establishing a DASD Repository for a Multi-Server Environment
Abstract
This chapter discusses the use of a repository to provide software updates in a timely manner. The best practices detail how the DASD repository saves time and effort in providing updates in a large distributed platform lab running mainframe software.
Kenneth/Stephen Barrett/Norris
Chapter 7. Staging for z/OS Optimization
Abstract
The z/OS and z/VM DASD files supplied by the vendor to create the virtualized mainframe systems allow rapid implementation of mainframe operating systems. These systems provide users access to many of the software and hardware features available in a traditional mainframe environment. However, limitations to the provided base environment include the following:

Chapter 8. Migrating to Mainframe zEnterprise DASD
Abstract
This chapter presents hints, tips, and general setup guidelines for establishing a virtualized environment using the operating system volumes from the mainframe zEnterprise. The chapter discusses and provides details for specific items that may require attention when migrating from the vendor-supplied system and DASD volumes to a new environment. Such items are not uniquely constrained. We highlight those that need to be considered generally, while omitting some items that vary with the diverse configurations within individual mainframe shops.

Chapter 9. Customizing the z/OS Environment with Symbols
Abstract
This chapter is a technical overview of techniques for running multiple systems utilizing:

Chapter 10. Updating the Environment
Abstract
This chapter provides an overview for updating the distributed server environment with more current versions of the operating systems and subsystems.
Kenneth/Stephen Barrett/Norris
Chapter 11. Preparing for Recovery
Abstract
The creation of a virtualized mainframe environment requires a significant investment in both capital and time. Once the environment is created, stability is extremely important. The environment must be protected from outages, but if a failure is incurred, there must be a mechanism to recover quickly.
Kenneth/Stephen Barrett/Norris
Chapter 12. Deploying Virtualized Mainframe Environments
Abstract
If several virtualized mainframe environments are to be created, multiple methods can be employed to complete the task.

Chapter 13. Software Licensing
Abstract
A software license governs the use and distribution of software. The license grants permission to use the software in certain ways and in certain environments. It is essential and necessary to ensure that all software loaded to the distributed environment is used legally and is not an infringement of its software licensing.

Chapter 14. Setting the Standards and Conventions
Abstract
Naming standards are a major part of managing virtual systems. When properly established, naming standards can enable the implementation of new operating systems and new virtual systems in an easy-to-follow process.

Chapter 15. IEASYS Member Example
Abstract
This appendix shows a full IEASYS member utilizing symbols and the parameter values after translation.

Chapter 16. LOAD Member Example
Abstract
The following LOAD member example is a singular LOAD member that, with naming standards, can facilitate multiple releases of the operating system without the need to change any of the parameters.
