InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.
Artificial Intelligence applications are increasingly built around Retrieval-Augmented Generation (RAG), semantic search, and AI agents. As these applications move into production, choosing the right persistence layer becomes just as important as selecting the LLM.
Today, I'm excited to announce the InterSystems IRIS Document Store for Haystack, a new open-source integration that enables developers to use InterSystems IRIS as a native Document Store within the Haystack AI framework.
When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.
These days, tokens signify security. JSON Web Token (JWT) Authentication has become one of the most popular standards for securing REST APIs. Fortunately for IRIS users, we have a straightforward way to set up applications to be protected this way. Yet, the idea is still similar to my old arcade days.
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.
If you start with InterSystems ObjectScript, you will meet the XECUTE command.
And beginners may ask: Where and Why may I need to use this ?
The official documentation has a rich collection of code snippets. No practical case.
Just recently, I met a use case that I'd like to share with you.
When you build an IRIS container with Docker, then, in most cases,
you run the initialization script
iris session iris < iris.script
This means you open a terminal session and feed your input line-by-line from the script.
And that's fine and easy if you call methods, or functions, or commands.
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.
Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.
Disclaimer: This guide is a good fit for Interoperability projects. When you have integrations, data flows, when you use IRIS for ETL processes, etc. Overall, when your code is combined with Productions.
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.
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:
We are looking at what we need to do to migrate from our current usage of Zen reports to InterSystems Reports. One of the hurdles for us is figuring out ways to interact with InterSystems reports programmatically from ObjectScript routines. There is a Java API for it, but it is possible to generate a report from InterSystems reports to a stream object in ObjectScript without diving into Java by using a %Net.HttpRequest.
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.
Run InterSystems IRIS inside of Home Assistant, as an add-on. Before you dismiss this article possibly under the guise that this is just a gimmick, Id like you to step back and take a look at how easy it is to launch IRIS based applications using this platform. If you look at Open Exchange, you will see dozens of dozens of applications worthy of launching while they are basically hung out to dry as gitware, and launchable if you want to get into a laptop battle with containerd or Docker. With a simple git repo, and a specification, you can now build your app on IRIS, and make it launchable through a marketplace with limited hassle to your end users. Run it along side Ollama and the LLM/LAM implementations, expose anything in IRIS as a sensor or expose an endpoint for interaction in your IRIS app to interact with anything you've connected to HAOS. Wanna restart an IRIS production with a flick of a physical switch or Assisted AI? You can do it with this add-on, or your own, right alongside the home automation hackers.
Hi all,
I am in need to use SCIM rest Api in cache class, could you please pour me some samples to use SCIM.

InterSystems IRIS is, among other things, a relational DBMS. This is why it supports all standard SQL indexes together with some additional ones. For beginners, the variety of index types in IRIS can feel a bit overwhelming. Thus, the goal of this article is to clarify when to use each and provide clear code examples.
Hi Community,

In the modern world, data is rarely uniform. Applications often require the structural rigidity of a relational database, the flexibility of a document store, and the performance of a high-speed key-value storage. Luckily, InterSystems IRIS solves this complexity by providing a single, unified engine that natively supports multiple distinct data models:
Crucially, all of these models access exactly the same physical data.
To illustrate this approach, let's examine all these data models using the same conceptual structure: The Record of Patient P101 (John Doe).
Hello everyone,
If you build, maintain, or troubleshoot solutions with ObjectScript, then I’m excited to share that the new InterSystems ObjectScript Specialist certification exam is now available to help you validate and showcase those skills!
Who should take the exam?
About the exam
If you're running IRIS behind IIS and get this error when trying to open the Lite Terminal in the vscode-objectscript extension:
WebSocket error: Error: Unexpected server response: 101
check your IRIS Web Gateway log. If you see:
level=SEVERE event=WebGateway.WebSocketError
This Web Server does not support WebSockets
the fix is to enable the WebSocket Protocol IIS feature, which is not installed by default.

.csvHello Community,
Artificial Intelligence tools are becoming part of many developers' daily workflows, and I'm curious how others are using them within the InterSystems ecosystem.
Are you using AI to:
- Generate ObjectScript code?
- Troubleshoot errors?
- Create SQL queries?
- Write documentation?
- Learn new InterSystems technologies faster?
I've found that AI can be a useful productivity tool, but I'm interested in hearing real-world experiences from the community.
What AI tools are you using, and where have you seen the biggest benefits or limitations?
Looking forward to your insights.
Hi all,
This is a quick tip about how to use case insensitive URL in REST API.
If you have a class that extends from %CSP.REST and Ens.BusinessService, to create a REST API service, and you have defined your WebApplication in lowercase
.png)
XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
<Route Url="/user" Method="POST" Call="User"/>
<Route Url="/login" Method="POST" Call="Login"/>
</Routes>
}Only accepts the url in lowercase, i.e. http://myserver/myproduction/user
If you have any uppercase character, the url doesn't work.
Hello community,
I wanted to share my experience about working on Large Data projects. Over the years, I have had the opportunity to handle massive patient data, payor data and transactional logs while working in an hospital industry. I have had the chance to build huge reports which had to be written using advanced logics fetching data across multiple tables whose indexing was not helping me write efficient code.
Here is what I have learned about managing large data efficiently.
Choosing the right data access method.
As we all here in the community are aware of, IRIS provides multiple ways to access data. Choosing the right method, depends on the requirement.
Set ToDate=+H
Set FromDate=+$H-1 For Set FromDate=$O(^PatientD("Date",FromDate)) Quit:FromDate>ToDate Do
. Set PatId="" For Set PatId=$Order(^PatientD("Date",FromDate,PatID)) Quit:PatId="" Do
. . Write $Get(^PatientD("Date",FromDate,PatID)),!InterSystems Reports version 25.3 is now available from the InterSystems Software Distribution site in the Components section. The software is labeled InterSystems Reports Designer and InterSystems Reports Server and is available for Mac OSX, Windows and Linux operating systems.
Don't let the minor release number fool you - there is a lot packed in this release. It includes a refreshed user interface - cleaner lines and fresher colors in "Light mode" and the ability to go back to "Classic mode" in your User Profile.
Hello!!!
Data migration often sounds like a simple "move data from A to B task" until you actually do it. In reality, it is a complex process that blends planning, validation, testing, and technical precision.
Over several projects where I handled data migration into a HIS which runs on IRIS (TrakCare), I realized that success comes from a mix of discipline and automation.
Here are a few points which I want to highlight.
