Every IBM i shop eventually faces the same deceptively simple question:
“How do we automatically monitor all USRPRF profiles and send a warning email listing every user whose password is about to expire?”
It sounds straightforward… until you try to build it.
Suddenly you’re juggling:
This chapter turns that messy, real‑world problem into a clean, structured learning journey.
- You’ll begin by exploring how to query and interpret user‑profile information programmatically, giving you a clear understanding of where IBM i stores password‑related attributes and how to extract them reliably. From there, the course guides you through the IBM i system APIs and commands that expose password‑expiry data, showing you how to work with system‑level structures and return formats in a clean, modern way.
- Once you can retrieve the data, you’ll build an RPG or CL‑based monitoring program designed to scan all user profiles and identify anyone whose password is approaching its expiration window. With that foundation in place, you’ll learn how to format and send automated email notifications directly from the IBM i, turning raw system information into a polished, actionable message.
- Finally, you’ll deploy the entire solution as a scheduled job so it runs quietly in the background, ensuring your organization receives timely warnings without any manual intervention.
Along the way, you’ll pick up modern IBM i development techniques, best practices for security‑related automation, and a deeper understanding of how the platform manages authentication behind the scenes.
By the end of the chapter, you’ll have a fully working password‑expiry monitoring tool, the kind of utility every IBM i administrator wishes they had, and every developer should know how to build.
More importantly, you’ll understand why it works, how to extend it, and where to apply the same techniques in your own applications.
Let’s dive in and turn a common operational headache into a clean, elegant IBM i solution.
