z/OS Application Development using RDz

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 the teaching of theory is kept to a minimum. Attendees will spend the majority of their time developing and testing COBOL (or PL/I) applications interactively.

This course is available for one-company, on-site presentations.

The next step

The recommended follow-on course is z/OS Communications Server Part 2 - Implementing TCP/IP under z/OS.


On successful completion of this course you will be able to:

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

Who Should Attend

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


Attendees should have pre-existing skills in COBOL or PL/I programming. Knowledge of CICS will also be an advantage.
