In this IBM® Redbooks® publication, we attempt to provide fresh insight into a problem domain that, in the authors' opinions, has been pushed to the back burner of technology writing for far too long—the domain of z/OS® (traditional) mainframe maintenance and production support. Since the mid-1980's, outside of a few websites and publications, this still-critical area of software has barely even received lip service by the world of mainstream technology media. In a small way, we are attempting address this situation. In this book, we provide information in "what and how to" sections on the value of z/OS maintenance and support—not the value of the software, which is hardly in question, but the value of the software developers, and how they collaborate, analyze, code, and test the applications, fixes, and enhancements under their responsibility. We present new 21st Century tools to help them achieve their goals more easily and effectively. These tools integrate and provide a 1 + 1 + 1 = 5 value-proposition, for companies that are still doing work the way they did when in the mid-1970's, when Gerald Ford was president of the United States. We are also describing, to a lesser extent, how you can effectively integrate the new tools with your existing development software stack, in order to find points of complimentary functionality. And we describe the new agile development and maintenance methodologies, and best practices for tools use and adoption. We hope that you find this work useful, and perhaps that it can fuel more discussion, future Redbooks publications, and other publications by IBM, or any vendor or group interested in this critical and vastly under-acknowledged technology domain.

This IBM® Redbooks® publication positions the new z/OS® Version 1 Release 11 for migration by discussing many of the new functions that are available. The goal for the z/OS platform is to eliminate, automate, and simplify tasks without sacrificing z/OS strengths, and to deliver a z/OS management facility that is easy to learn and use. z/OS is a highly secure, scalable, high-performance enterprise operating system on which to build and deploy Internet- and JavaTM-enabled applications, providing a comprehensive and diverse application execution environment. This books describes the following new and changed functions: - IBM z/OS Management Facility - Allocation enhancements in z/OS V1R11 - BCPii function enhancements in z/OS V1R11 - JES2 and JES3 enhancements - zFS file sharing enhancements - Extended access volume enhancements - Choosing whether to run zAAP work on zIIP processors - System REXX enhancements in V1R11 - RRS global panel options - Service aids enhancements in V1R11 - GRS ENQ contention notification enhancements and analysis for GRS latches - Basic HyperSwap® support enhancement - Message Flood Automation enhancements - Program Management new Binder IEWPARMS - Predictive failure analysis (PFA) - SMF enhancements in V1R11 - System Logger enhancements - XCF/XES enhancements in V1R11 - AutoIPL support - Displaying PDSE caching statistics - ISPF enhancements - IBM Health Checker for z/OS enhancements

The IBM® CICS® Interdependency Analyzer (CICS IA®) is a runtime tool for use with IBM CICS Transaction Server for z/OS®. CICS IA allows both system programmers and application developers to get an understanding of the relationships and dependencies of your CICS applications and the environment on which they run. By analyzing data collected by CICS IA, you can make changes to your environment in a safe and controlled but timely manner to address changing demands on your business applications. In this IBM Redbooks® publication, we first provide a detailed overview of what CICS IA is and what business issues it addresses before we review how to configure CICS IA to collect the data that you require with the minimum provenance impact. We then show how you can analyze this data to assist with day-to-day application changes and major projects such as application onboarding.

This book constitutes the thoroughly refereed proceedings of the 11th International Conference on Evaluation of Novel Approaches to Software Engineering, ENASE 2016, held in Rome, Italy, in April 2016. The 11 full papers presented were carefully reviewed and selected from 79 submissions. The mission of ENASE is to be a prime international forum to discuss and publish research findings and IT industry experiences with relation to the evaluation of novel approaches to software engineering. The conference acknowledges necessary changes in systems and software thinking due to contemporary shifts of computing paradigm to e-services, cloud computing, mobile connectivity, business processes, and societal participation.

The IBM® Operational Decision Manager product family provides value to organizations that want to improve the responsiveness and precision of automated decisions. This decision management platform on IBM z/OS® provides comprehensive automation and governance of operational decisions that are made within mainframe applications. These decisions can be shared with other cross-platform applications, providing true enterprise decision management. This IBM Redbooks® publication makes the case for using Operational Decision Manager for z/OS and provides an overview of its components. It is aimed at IT architects, enterprise architects, and development managers looking to build rule-based solutions. Step-by-step guidance is provided about getting started with business rules by using a scenario-based approach. This book provides detailed guidelines for testing and simulation and describes advanced options for decision authoring. Finally, it describes and documents multiple runtime configuration options. This third edition, SG24-8014-02, of this IBM Redbooks publication updated the information presented in this book to reflect function available in IBM Operational Decision Manager for z/OS Version 8.7.1.

This IBM® RedpaperTM publication introduces you to IBM Cloud Provisioning and Management for z/OS®. The paper was written to coincide with the announcement of IBM Cloud Provisioning and Management for z/OS and the software is not yet generally available (GA) at the time of this writing. As such, any examples that are shown are subject to change at any time before the software is GA. The goal of this paper is to provide you with an initial overview and more information to support the announcement. You might be new to clouds, or heard of many different variations of what a cloud might be. Therefore, it is useful to begin with establishing an understanding of cloud computing concepts. The paper describes the provisioning and management of z/OS middleware and explains how these aspects can be offered as a cloud service.

What is IBM® Multi-Factor Authentication (MFA)? IBM MFA consists of the following elements: Something that you know, such as a Personal Identification Number (PIN) or a password. Something that you are, such as a finger print or retinal scan. Something that you have, such as a hard token (for example, a key fob or soft token), which is software-based). This IBM RedpaperTM publication helps you install, customize, and configure IBM MFA for z/OS® V1.1.0. It also provides information that is based on our experience in a controlled environment.

IBM® Problem Determination (PD) Tools consists of a core group of IBM products that are designed to work with compilers and run times to provide a start-to-finish development solution for the IT professional. This IBM Redbooks® publication provides you with an introduction to the tools, guidance for program preparation to use with them, an overview of their integration, and several scenarios for their use. If an abend occurs during testing, Fault Analyzer enables the programmer to quickly and easily pinpoint the abending location and optionally, the failing line of code. Many times, this information is all the programmer requires to correct the problem. However, it might be necessary to delve a little deeper into the code to figure out the problem. Debug Tool allows the programmer to step through the code at whatever level is required to determine where the error was introduced or encountered. After the code or data is corrected, the same process is followed again until no errors are encountered. However, volume testing or testing with multiple terminals is sometimes required to ensure real-world reliability. Workload Simulator can be used to perform this type of testing. After all of the tests are completed, running the application by using Application Performance Analyzer can ensure that no performance bottlenecks are encountered. It also provides a baseline to ensure that future enhancements do not introduce new performance degradation into the application. This publication is intended for z/OS® application developers and system programmers.
