It’s time to talk about IBM Rational Developer for IBM i

What is RDi?

An integrated development environment (IDE) built on the Eclipse platform, designed for creating and maintaining applications on IBM i systems.

IBM Rational Developer


This basically means Rational Developer for IBM i (commonly known as RDi) is IBM’s flagship integrated development environment for the IBM i platform.

The product isn’t universally used across the IBM i community, because it’s not free. It’s actually very expensive (IMHO of course) and those software developers that can afford it enjoy the productivity improvements they get from a graphical and modern IDE, particularly compared to older greenscreen coding environments like PDM and SEU.

In the past I may have answered something like “PDM and SEU are old and Rational Developer for i is a modern tool for RPG and COBOL development.” With the exception of a few leading-edge IBM i developers, this answer generally doesn’t go over very well (much the same way that I’ve learned “Because I said so” doesn’t work that well with my kids). Over the past year I’ve transitioned to starting all RDi demos with two slides: What is RDi and Why use RDi? I’ll explain the “Why RDi” here.

The short answer to why RDi can be summarized as:

  • Improve developer productivity
  • Common development tools platform
  • Improve developers skills

If you would like to investigate RDi in more detail then let’s dive in:
