The Missing Link: Unlocking the Power of TSO and CMS with REXX is the ultimate guide to unlocking the power of REXX, a versatile scripting language that enhances the capabilities of TSO and CMS operating systems. Written for an American audience, this comprehensive book provides a thorough exploration of REXX, empowering readers to automate tasks, customize their environments, and extend the functionality of various applications. The book begins with a solid foundation in REXX fundamentals, covering syntax, data types, variables, operators, and program structure. Readers will learn to create simple REXX programs and gradually progress to more advanced techniques, including arrays, lists, subroutines, functions, and error handling. Beyond the basics, the book delves into the integration of REXX with other TSO and CMS commands, enabling readers to automate tasks, customize menus and dialog boxes, and extend the capabilities of ISPF. The utilization of REXX in QMF and Dialogue Manager is also covered in detail, providing readers with the skills to enhance reporting and automate processes. The book's focus on practical applications makes it an invaluable resource for REXX users of all levels. Readers will learn how to develop REXX scripts for system administration, network management, data processing, and business process automation. Numerous examples and case studies illustrate how REXX can be used to solve real-world problems and improve productivity. Additionally, the book includes a comprehensive reference guide to REXX verbs, functions, and reserved variables, making it an essential companion for both novice and experienced REXX programmers. Troubleshooting tips and techniques help readers identify and resolve errors in their REXX programs, ensuring successful implementation and maintenance.

Introduction To The New Mainframe Security written by Rica Weller and has been published by IBM Redbooks this book supported file pdf, txt, epub, kindle and other format this book has been release on 2007-04-26 with Computers categories.

This book provides students of information systems with the background knowledge and skills necessary to begin using the basic security facilities of IBM System z. It enables a broad understanding of both the security principles and the hardware and software components needed to insure that the mainframe resources and environment are secure. It also explains how System z components interface with some non-System z components. A multi-user, multi-application, multi-task environment such as System z requires a different level of security than that typically encountered on a single-user platform. In addition, when a mainframe is connected in a network to other processors, a multi-layered approach to security is recommended. Students are assumed to have successfully completed introductory courses in computer system concepts. Although this course looks into all the operating systems on System z, the main focus is on IBM z/OS. Thus, it is strongly recommended that students have also completed an introductory course on z/OS. Others who will benefit from this course include experienced data processing professionals who have worked with non-mainframe-based platforms, as well as those who are familiar with some aspects of the mainframe environment or applications but want to learn more about the security and integrity facilities and advantages offered by the mainframe environment.

This IBM® Redbooks® publication discusses in detail the facilities of DB2® for z/OS®, which allow complete monitoring of a DB2 environment. It focuses on the use of the DB2 instrumentation facility component (IFC) to provide monitoring of DB2 data and events and includes suggestions for related tuning. We discuss the collection of statistics for the verification of performance of the various components of the DB2 system and accounting for tracking the behavior of the applications. We have intentionally omitted considerations for query optimization; they are worth a separate document. Use this book to activate the right traces to help you monitor the performance of your DB2 system and to tune the various aspects of subsystem and application performance.

Threadsafe Considerations For Cics written by Chris Rayns and has been published by IBM Redbooks this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012-04-05 with Computers categories.

Beginning with IBM® CICS® Version 2, applications can run on TCBs apart from the QR TCB, which has positive implications for improving system throughput and for implementing new technologies inside of CICS. Examples of implementing new technologies include using the IBM MVSTM Java virtual machine (JVM) inside CICS and enabling listener tasks written for other platforms to be imported to run under CICS. The newest release, CICS Transaction Server for z/OS® (CICS TS) V4.2, includes scalability enhancements so that you can perform more work more quickly in a single CICS system. The advantage of this enhancement is that you can increase vertical scaling and decrease the need to scale horizontally, reducing the number of regions that are required to run the production business applications. The scalability enhancements in CICS TS V4.2 fall into two broad areas, which are increased usage of open transaction environment (OTE) and of 64-bit storage. This IBM Redbooks® publication is a comprehensive guide to threadsafe concepts and implementation for IBM CICS. This book explains how systems programmers, applications developers, and architects can implement threadsafe applications in an environment. It describes the real-world experiences of users, and our own experiences, of migrating applications to be threadsafe. This book also highlights the two most critical aspects of threadsafe applications: system performance and integrity.
