  • 16520: Application Development for Z/OS - Not Your Father's Green Screen
    16520: Application Development for z/OS - Not your Father's Green Screen Rosalind Radcliffe Distinguished Engineer, IBM Academy of Technology Member IBM Corporation [email protected] @RosalindRad Insert Custom Session QR if Desired. Abstract Ask most people how they write and maintain applications on z/OS and you hear "oh, you use this thing called a green screen" followed by a chuckle. In reality, application development for zEnterprise applications has been transformed over the past several years to the point where application developers enjoy the same or better features from integrated development environments as programmers who work on other platforms. Advances in remote system communication and interaction, syntax- highlighting, parsing, and code understanding for Assembler, PL/I, C/C++, and COBOL source code, as well as programming assists such as code snippets and templates are all available to application programmers. Interactive debug of applications, written in multiple programming languages and running in various runtime environments is also possible and can greatly boost programmer productivity. Come and learn about how these features can enable application developers who are new to the mainframe to interact with, update, and efficiently enhance mainframe applications. 16721: Decision Management: Making the Right Change, at the Right Time 3/4/15 3 IBM DevOps point of view Enterprise capability for continuous software delivery that enables organizations to seize market opportunities and reduce time to customer feedback Continuous

  • Mainframe to Enterprise to the Is Curriculum
    https://doi.org/10.48009/2_iis_2012_182-192 Issues in Information Systems Volume 13, Issue 2, pp. 182-192, 2012 MAINFRAME TO ENTERPRISE TO THE IS CURRICULUM Joseph Packy Laverty, Robert Morris University, [email protected] Frederick G. Kohun, Robert Morris University, [email protected] John Turchek, Robert Morris University, [email protected] David Wood, Robert Morris University, [email protected] Daniel Rota, Robert Morris University, [email protected] ABSTRACT Over the decades the concept of a mainframe has been synonymous to IBM operating systems and the COBOL programming language. While object-orientated programming languages, web interface transaction systems, web services, distributed services, and mobile application topics are frequently included in the IS/CS curriculum, this paper considers the inclusion of IBM Enterprise Systems. IBM zEnterprise has evolved into an integrated, scalable, enterprise system which supports legacy applications, open-source applications and tools, DB2, Cognos, SPSS, data mining and Rational project management tools. The growth and market penetration of IBM zEnterprise has been spectacular. This evolution of IBM Enterprise Systems provides many opportunities for IS/CS majors. A case study implementing the IBM Academic Initiative in an ABET-CAC curriculum is presented. KEYWORDS: IBM Academic Initiative, IS Curriculum, IBM zEnterprise, ABET-CAC, z/OS, COBOL, CICS, DB2, Open Source, Rational Application Developer for Z Systems, Robert Morris University, Marist College INTRODUCTION Over the decades the concept of a mainframe has been synonymous to IBM operating systems and the COBOL programming language [1]. In recent years, computer hardware evolved in various directions, e.g., desktop, blade servers, super computers and mobile devices.

IBM Software Installation instructions for the Rational Team Concert V4.0 Enterprise Extensions Build Administration Workshop This preparation document will take you through the setup of the infrastructure required to complete the EE Build Administration Workshop. The necessary components can be downloaded from https://jazz.net/downloads/. Note that instead of a step-by-step installation and configuration walk- through, reference information will be provided to guide you through these tasks. The necessary workshop infrastructure can be either: a) An existing Rational Team Concert installation. In this case, you can use this document to make sure that all the components needed for the workshop are installed, and you have expected users and licenses available in your environment. b) A new installation. This document provides you with reference information for this task. Keep in mind that the outlined steps are a one-time setup and would likely be executed by a system administrator (product install and configuration). This role is distinctly separate from the role of the EE Build Administrator, which is the focus of the this workshop. Using an existing environment? Make sure your Jazz user for the workshop has the needed license assigned (IBM Enterprise Platforms license) in your CLM server environment, and take note of your build environment details to be used in the workshop: • z/OS build machine hostname • Build agent port • TSO ID and password for connection to build agent • ISPF Gateway startup script location The sections and topics covered in this document are the following: 1.
