Hi Community!

Join us as we take a closer look at the winning projects of the InterSystems Programming Contest: AI Agents for FHIR.

IRIS Health (Community) 2026.1.0.235.2 failing to start - any tips on how to reset things without doing a full reinstall?

We use Ensemble 2018 for our production servers, and have local instances for developers running fine. We are gearing up for the move to Iris, and are using the Community edition of Iris Health to check that our existing productions all work OK.

I installed IRIS Health in mid-May alongside my existing Ensemble instance, and have it configured to auto-start when my laptop boots.

We have some exciting news to share! 🎉

On June 30, 2026, Global Masters will move to a new platform with a refreshed experience and some long-awaited features.

The best part? All the progress you've worked hard to earn will come with you. Your points, badges, and rewards history will be preserved, and we're also bringing back Levels — one of the most requested features from our community. ✨

All active Global Masters challenges will be available on the new platform, so you'll be able to continue your journey without missing a step.

What Do I Need to Do?

I'm having trouble installing InterSystems IRIS for Health Community 2026.1.0.235.2 (Windows x64).

The installation completes most of the process, but then rolls back every time.

What I've already tried:

• Uninstalled the previous IRIS installation.
• Deleted all remaining IRIS files and directories from the file system.
• Rebooted Windows.
• Re-ran the installer as Administrator.
• Attempted a completely fresh installation multiple times.

Despite this, every installation rolls back.

Looking in messages.log

Arabic text inserted into MySQL (Azure Database for MySQL 8.4) from Ensemble comes out corrupted, even with `utf8mb4` configured at every layer we can reach. We've isolated this to the Ensemble → ODBC → MySQL path specifically, tried several fixes, and tested it through two different Ensemble-side code paths with identical results. Looking for guidance on what else to check, or confirmation this is a known limitation.

Environment

- Ensemble (Ensemble-based Production)
- Target: Azure Database for MySQL
- Driver: MySQL Connector/ODBC 8.

Some of you in our developer community have probably heard of AI Hub, but for those who haven't, here's the official definition:

InterSystems AI Hub is an agent-based AI orchestration and enablement platform that integrates the InterSystems IRIS data platform with external AI tools and large-scale language models (LLM). Currently available through the Early Access Program, it simplifies the creation of agent-based workflows directly on top of existing enterprise data.

Here you can see an applied example of AI Hub developed by @Gabriel Ing and that I have used to implement this example.

Hi everyone,

I am sending SDA messages to an EDGE with PDFs (stream) on it. I need to know the size of those message to estimate how much of a HD was used in the last 24 hours, for example.

Do you know to do it?

Thanks in advance

https://github.com/rochus-keller/MUMPS is new implementation of the 1976 MUMPS standard. The README gives an excellent background. There is also language primer by the author.

This is a part of a series where the author explore legacy programming languages of significance; other notable mentions are Simula, Smalltalk, Cedar, Interlisp, and Lisa Pascal.

Hey Community,

Round 1 of the Community Bounty Program "Idea to Application" is officially open. Three ideas from the Ideas Portal are ready to be implemented — pick one or more, build it, publish it on Open Exchange, and earn Global Masters points. 

🏅Every qualifying submission earns a Credly badge, Global Masters badge, and 10k+ points. Implement all ideas this round and unlock Tier 2 rewards.

It all started on a train ride to visit my parents, while I was chatting with a neighbor in my compartment. As it usually goes, the talk turned to technology, and she threw out a highly specific question: *Could ChatGPT be used to analyze the human genome?* I was highly skeptical that it could pull off something that complex. But the question lingered, burrowing into my mind. By the time I walked through my front door, my skepticism had transformed into a challenge. I didn't have a genome sequencing dataset on hand, but I did want to see if standard ChatGPT could build a functional Interoperability Production from scratch using the PyProd package. Besides, that would give me the chance to participate in the 1st round of the Community Bounty Program "Idea to Application" implementing the third idea.

Hi Community,

Data Transformation Language (DTL) is one of those tools that appears deceptively simple at first—drag a source field, drop it on a target, and you are done. However, once you start working on real-world integration projects, you quickly realize that raw field mapping only gets you so far. The true challenge begins when you need to validate field lengths, clean up incoming strings, strip unwanted characters from IDs, or produce timestamps in a specific format required by a downstream system.

A Better Developer Experience With PollingBusinessService

One of the most visible additions in 4.0.0 is PollingBusinessService.

Before this release, creating a scheduled Python business service meant dealing directly with the low-level inbound adapter pattern. In 4.0.0, a scheduled Python entry point can be written directly as a PollingBusinessService and the framework uses the default IRIS inbound adapter behind the scenes.

Hi everyone!

My name is Nikita Mikhailov, and I am a backend engineer with 4 years of experience specializing in InterSystems IRIS, ObjectScript, MUMPS, and .NET. I thrive on untangling legacy codebases, solving complex concurrency or performance bottlenecks, and building clean, modern APIs.

Key Highlights from my work:

• Performance Optimization: Slashed average API response times by 90% (from >1s down to ~100ms) by implementing custom caching layers and background processing.

Hi everyone,

I am testing an OAuth2 setup on InterSystems IRIS 2026.1 (Community Edition), based on a workshop with separate Auth Server and Resource Server instances (https://community.intersystems.com/post/learn-how-use-oauth2-openid-con…).

On the Resource Server, when I try to use Dynamic Registration and Save in OAuth 2.0 Client Configuration, I get this error:

ERROR #8881: Dynamic client registration endpoint is not configured.

What I already checked:

1. OAuth2 Server configuration exists on the Auth Server.
2. Issuer endpoint is set and reachable.

I am going to share some of the things I find very useful about VS Code, after many years developing in Studio.

The first and obvious thing to me is the fact that it does not crash in the middle of development when it disconnects from the network for any reason, forcing you to restart Studio and deal with the risk of losing valuable code. I also find VS Code a lot quicker than Studio, and the user interface far better with so many ways to customise it to your liking.

In France we use farm animal names for our dev and test environments.

I'm approaching the need to send notifications through a Microsoft Exchange or Gmail servers. however my last foray into this, I was blocked due to an issue inside my SSL certificate is what I thought after the attempt.

So my attention will be on trying to match the cryptography in the SSL certificate I produce compared to the mail server I'm trying to use.

Has anyone else had an issue with this approach? My other option is Amazon SNS potentially. I do have a functional MS Teams channel for alerts, and can make different notification channels as well.

Any help or insights are appreciated. 

Hi all,

I am in need to use SCIM rest Api in cache class, could you please pour me some samples to use SCIM.

Actually, I need to form the JSON request for SCIM request for User Provision.

Could you please help me on this? 

Thanks in advance,
