z/OS application development with RDz

Intended for

Application programmers who are going to develop traditional 3270 and/or batch applications using the RDz COBOL and/or PL/I features.

Background

The students should be experienced in COBOL (see COBOL programming - part 1) or PL/I (see PL/I programming: fundamentals course). Basic knowledge of CICS is an advantage.

Training method

Theory is kept to a minimum. The delegate spends most of the time on developing and testing COBOL (or PL/I) applications interactively.

Course leader

Guido Indesteege.

Duration

2 days.

Schedule

No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested ? Please contact ABIS.

Objectives

Traditional mainframe application development for batch applications or on-line transactions has been done for decades using the TSO/ISPF environment. IBM's RDz (Rational Developer for System z) facilitates the development process by offering a complete integrated workbench for coding, testing and debugging these applications. The development can be done locally, but at any stage with a connection to the remote z/OS.

In this course, participants learn:

  • to use RDz for the development of traditional mainframe oriented applications, written in COBOL or PL/I;
  • to structure and debug these applications efficiently, either locally or remotely;
  • to know the new possibilities for integrating legacy applications, based on XML and SOAP;
  • to deploy the applications on the z/OS.

Main topics

  • RDz workbench as Integrated Development Environment
  • navigation in the workbench • perspectives • views • editors
  • debugging • incremental compilation • code import and export
  • z/OS perspectives and views
  • z/OS projects
  • COBOL /PL/I editor
  • JCL editor and job submission • spool monitor
  • dataset utilities
  • Local vs. remote configuration
  • projects • build • source code debugging
  • using CICS facilities (CICS for Windows or CICS TS)
  • XML enablement for COBOL
  • Deployment
