#InterSystems IRIS

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 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 Community,

⏯  Startup Forum @ Ready 2026

I have a Business Operation calling a SOAP WebClient method via InvokeMethod, passing several individual parameters. The call returned $$$OK with no SoapFault, but the output object came back undefined, causing a downstream error when I tried to use it. Turns out the generated WebClient method had been refactored to accept a single request object instead of individual parameters, so my call no longer matched the signature. My question: is this expected — InvokeMethod failing silently (no SoapFault, no error status) when parameters don't match the target method's signature?

One the main differences is the plugin system. Because in VS Code, everything is built around extensions. For example, for InterSystems development, you have the "InterSystems ObjectScript Extension Pack" that includes the essential tools. With this plugin you can connect to InterSystems servers, browse code, edit classes, compile, and work with ObjectScript directly from VS Code.

And it's not just for ObjectScript. VS Code also supports Git, Docker, REST clients, YAML, JSON, Python, and many other technologies.

Hello everyone,

I am new to InterSystems IRIS and would like to know which resources you recommend for beginners.

I have already explored some of the documentation, but I would appreciate suggestions for tutorials, videos, training courses, or hands-on exercises that helped you learn the platform.

What learning path would you recommend for someone just getting started?

Thank you in advance for your advice.

Hi folks!
Our community is growing rapidly, and the knowledge base is incredibly vast. Whether you're a newbie, confused, and unsure where to start, or a seasoned IRIS veteran who occasionally forgets a few basic rules (it's normal and happens to everyone!), you'll find this brief overview of IRIS basics and all its wonders useful.
Here I'd like to begin a series of articles dedicated to this topic.
There will be eight main topics in total:

1. InterSystems ObjectScript
2. Build with REST APIs
3. Managing Data Models
4. Explore Integrated ML
5. Interoperability & Integrations
6. Introduction to IRIS HealthShare products
7. Analytics & Business Intelligence
8. Deployment & DevOps

Each of them will consist of four parts: Courses, Community articles, Documentation, Applications

This particular part will cover InterSystems ObjectScript. For your convenience, all categories will be hidden under a spoiler.
 

Hi, Community!

Have you tried the InterSystems AI Hub, available through the Early Access Program?

The AI Hub integrates InterSystems IRIS® data platform with external AI tools. Get an overview in this video:

Building AI Applications with InterSystems AI Hub 

Hey All!

I wanted to reach out and get some advice on the best way to interact with a external SQL database, as I'm finding the documentation quite confusing to follow. I'm new to using SQL within InterSystem, and I want to make sure I'm following the best practices.

In essence, what I am trying to achieve, is extracting certain values from a HL7 message and then insert those message field values into an external database. The ODBC, DSN and Credentials details are all setup and working correctly.

Hello everyone,

For the past few days, I have been experiencing a strange issue with the InterSystems Server Manager in VS Code (v.2.8.3).

Sometimes, while working on a .cls class in client-side mode (editing files locally and pushing them to the server through the VS Code extension), the extension unexpectedly starts recompiling the same class multiple times. The compilation itself completes successfully, but as soon as it finishes, another compilation of the same class is automatically triggered.

Hey Community!

We're happy to share the first video in the "InterSystems Instruqt Walkthroughs" series on our InterSystems Developers YouTube:

⏯ Data Models of InterSystems IRIS - InterSystems Instruqt Walkthrough

A vector-search knowledge base of past clinical assessments, running on InterSystems IRIS, gives the LLM a deterministic calibration signal — making its triage reasoning faster, more structured, and clinically defensible.

The Problem with Probabilistic Medicine

The LLM answered correctly. But would it answer the same way for the next patient with the same profile? Same conditions, same medications, same symptoms — would the risk score drift? Would the priority shift from "emergency" to "urgent"? Would the follow-up tasks be different?

When installing InterSystems IRIS on Windows, you may see the following option in the installer wizard if IIS has already been installed and enabled (Enable IIS).

Note: Depending on your installation type, you may not see this exact installer screen. In that case, proceed with installation as normal, and then configure the IIS settings on the server where the Web Gateway is installed.

If you choose to configure the local IIS web server for the instance, the installer wires IIS and the InterSystems Web Gateway together for you.

Amazon SQS (Simple Queue Service) is a managed message queue service that provides a simple, durable, and scalable mechanism for exchanging messages between applications. It is particularly well suited for event-driven integration patterns and loosely coupled architectures.

Bear in mind that the AWS SQS adapter is based on InterSystems PEX Network and requires the Java External Server to be enabled.

When using Amazon SQS you can either take the role of a Consumer or a Publisher.

In my first article, I described the baseline version of the FHIR Patient Snapshot Agent: a Streamlit and Python application that retrieves FHIR resources from InterSystems IRIS for Health and uses an LLM to generate a concise patient summary.

This follow-up article explains how I extended the project with two additional InterSystems-focused features:

• Source context vector search
• Embedded Python artifacts for IRIS-compatible review

The goal was to make the project more useful as a clinical summarisation prototype while keeping the design small enough to understand and reproduce.

• YouTube demo: https://youtu.be/Hsu10Nnujng

Overview

FHIR Patient Snapshot Agent is a small open-source application built for the InterSystems AI Agents and FHIR Programming Contest.

The project implements the suggested Smart Patient Summary Generator idea: it retrieves structured FHIR resources for a selected patient and generates a concise, role-specific patient summary.

The goal is not to diagnose or recommend treatment.

 Hi everyone,

I've been exploring the growing use of AI agents and LLM-powered workflows with InterSystems IRIS and InterSystems IRIS for Health.

I'm curious to learn how others in the community are approaching this.

• Are you currently using AI agents in production or testing environments?
• What use cases have delivered the most value so far?
• Have you integrated IRIS with models such as GPT, Claude, or other LLMs?
• What challenges did you encounter during implementation?

I'm especially interested in hearing about healthcare, automation, data integration, and decision-support scenarios.

InterSystems Programming Contest: AI Agents for FHIR at https://openexchange.intersystems.com/contest/46 . 

Code: https://github.com/eungi-hong/central-park

Demo: https://triagepark.78-47-167-98.sslip.io/ 

The first ten minutes of a visit are always the same: take the history, pull the record, cross-check the medications, decide how urgent it is. Triage Park does that first pass as a team of AI agents running entirely inside InterSystems IRIS for Health, and hands the clinician a cited, explainable handoff. The part most "AI triage" demos skip is the part we cared about most: safety

The successful construction and implementation of AI agents to address diverse use cases in the healthcare sector depend on high-quality data and APIs, effective governance, and management. The InterSystems IRIS FHIR server delivers all of this and is also fluent in Python, Vectors, and Interoperability. Combined with a strong LLM, patients, physicians, caregivers, and managers gain access to state-of-the-art technology for personal and public health.

Hi folks!

Suppose a new version of your amazing software solution built on IRIS needs some persistence change: some data needs to be converted, some classes get new properties or even renamed, and some data should be prepopulated for newly introduced persistent classes to keep the whole application data consistent.

What are your approaches? 

SQL-based scripts? ObjectScript, or Python? for both directions of migration, up and down? 

Do you autogenerate it with Claude/Codex? What about data-consistency tests?

COuld you please share your thoughts? or libraries?

 Hello Community,

I am learning more about InterSystems IRIS administration and would like to understand the recommended approach for monitoring performance in a production environment.

What tools, metrics, or dashboards do you typically use to monitor system health, database activity, and application performance?

I am particularly interested in learning which indicators are most useful for identifying potential bottlenecks before they affect users.

Thank you for sharing your experience and recommendations.

Most "AI agent + FHIR" projects end up with the same shape: a FHIR server over here, a vector database over there, and a Python service in the middle whose job is to call an embedding API, marshal float arrays back and forth, and keep two datastores in sync. Three moving parts, two network hops, and an embedding client you now own forever.

Triage Park: our entry for the InterSystems Programming Contest: AI Agents for FHIR, doesn't have any of that. The agent never computes an embedding. It never imports an OpenAI embeddings client. There is no vector database.

The rise of distributed systems and cloud-native architectures within large institutions has redefined hosting for InterSystems IRIS interoperability applications (productions). In modern environments, the standard layout involves at least two production instances operating on distinct nodes under a load-balancing configuration to handle requests.

The benefits are clear: you can now scale dynamically based on request volume, increasing the number of active productions during peak demand and going down when traffic subsides.
