Data Collection

This is a step-by-step instruction guide for creating a task to collect data about the InterSystems database and globals therein (as seen in the associated Open Exchange App - find all the associated code there)

UPDATE (Aug 1 2024): Recently I've been asked about the differences between this and the History Monitor functionality. In short, the data collection monitor builds on the history monitor by adding the ability to track growth of individual globals.

Hey Community,

More than 1,100 applications are already available for everyone to download on the InterSystems Open Exchange. 

And now it's time to announce the best developers and the most downloaded apps of 2025!

Let's take a closer look at our heroes and their apps:

I'm happy to share that I was invited to present on the Developer Ecosystem and how it helps everyone become better programmers at the meetup during Iberia READY 2026. Thus, I had a chance to participate in this great event. And you have a chance to see how it went on, because as usual, I will share photos and impressions!

When I arrived, the first thing I saw was the Developer Zone and my presentation about the Ecosystem 🤩

Hi Community!

We’re excited to announce the launch of a new, hands-on training program:

 🧑‍💻 Developing FHIR Applications Using Python 🧑‍💻

This cohort-based course takes developers from FHIR fundamentals to advanced, real-world healthcare interoperability solutions, with deeper, more practical coverage than typical industry offerings and a strong focus on production-ready skills using InterSystems technology.

You’ve seen how tools like Lovable are shaking up web development. People are spinning up entire apps just by talking to an AI, almost like pair‑programming on steroids.

Now imagine bringing that same “vibe coding” experience into healthcare. know, it sounds crazy. Healthcare is complex, full of regulations, and usually gives us a headache just thinking about the interoperability rules.

That’s exactly the space where withLove lives: an AI‑Native, Low‑Code platform built entirely on InterSystems IRIS for Health.

And no, this is not “one more chatbot” that spits out half‑broken code for you to

Hi Developers!

Recently we are getting a lot of requests on how to become an active and helpful member of the InterSystems Developer Community.

The terms are very simple:

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

• A persistent data class
• A REST class with GET and POST methods
• A web application to expose the API

• A full demonstration using Docker

I need to reproduce a table (in fact a view, but let's start with a simple table 😊) in IRIS as the currently used in Oracle.

I need to expose/project one column to JDBC as CLOB, in my class I have the corresponding property defined as:

Property GlobStream As %Stream.GlobalCharacter;

In JDBC this column is projected as LONGVARCHAR, this is compliant with the documentation but I need to project it as CLOB.

In addition, I'm no expert in JDBC but wit seems that LONGVARCHAR has a Maximum Length 32,700 characters in JDBC, not quite enough for an arbitrary stream.

Is it possible to project a %St

What is the actual valid version with ML ??

I have a persistent class (GetOrgUpdatesResponse) that has a property which is a list of another persistent class (Organization).

What would be the best way to cascade deletes so that on deletion of a parent row each object in the list property is then also deleted? 

I have included a sample of my classes here for clarity

Property Organizations As list Of Organization;// Cascade DeletionProperty NextUpdateBatchID As%String;Property ResultStatus As%String;

Picture a dark room. The only light comes from a wall of displays and a blinking prompt that politely informs you:

“LINK TO M-U5K-3T: HIGH LATENCY – DIRECT CONTROL DISABLED.”

Perfect.

You are supposed to be a Rover Commander in the Musketeer Corps. Somewhere absurdly far away, you have an autonomous unit parked on a hostile exoplanet. It wants you dead, but it’s also covered in minerals that could fund a small civilization.

The ore on M-U5K-3T is everywhere. Unfortunately, everything else on the surface is actively trying to kill you.

So, we don't pilot. We script.

Update (Feb 22): The migration has been successfully completed. You may still experience some temporary instability. If you notice any issues, please report them via DC GitHub.

Hi Developers!

Please note that the Developer Community will undergo scheduled maintenance on February 21–22, 2026.

Hi developers!

Observing the avalanche of AI-driven and vibe-coding developer tools that have been appearing lately almost every month with more and more exciting dev features, I was puzzled whether it is possible to leverage it with InterSystems IRIS. At least to build a frontend. And the answer - yes! At least with the approach I followed.

Here is my recipe to prompt the UI vs InterSystems IRIS Backend:

1. Have the REST API on the IRIS side, which reflects some Open API (swagger) spec.
2. Generate the UI with any vibe-coding tool (e.g., Lovable) and point the UI to the REST API endpoint.
3. Profit!

Here is the result of my own exercise - a 100% prompted UI vs IRIS REST API that allows to list, create, update delete entries of a persistent class (Open Exchange,frontend source, video):

What is the recipe in detail?

Hi developers. Just want to share with you a finding that might save you a few important minutes of your developer life with InterSystems IRIS.

But!

It should work; you deployed the REST API correctly, and everything is just in place.

What can go wrong?
