Increasing complexity of IBM System i development

The world of the IBM System i™ platform has changed dramatically. Not long ago, the management of System i source code and resources was relatively simple. The Data Description Specification (DDS) was used for database files, IBM 5250 screen layouts and reports. Developers created code with the Report Program Generator (RPG), Command Language (CL) and Common Business Oriented Language (COBOL) programs, and stored the code in source files in System i libraries on the IBM eServer™ i5 platform. This source code could then be compiled into executable objects or programs and copied or moved into test libraries. Upon completion of integration testing, the new objects were deployed on a production machine or into a production environment. Developers all worked in a single location and walked to teammates’ cubicles to coordinate on issues pertaining to the deployment of new or modified applications.

Today, the System i development process is complicated by globalization, the rapid pace of technology innovation and new ways of doing business. Companies must now be able to demonstrate that their computer systems meet the requirements of regulatory bodies and the compliance demands of auditors. And their information technology (IT) and systems organizations must address the technical challenges of integrating new technologies, operating systems and distributed development environments.

This paper discusses how IBM Rational® ClearCase® and IBM Rational ClearQuest® software can help organizations manage System i application development in increasingly complex environments that include:

  • Multiple languages, technologies and even open source or platform-based environments
  • Projects that involve in-house, offshore and third-party developers located in various sites around the world
  • Compliance with numerous regulatory and industry mandates
