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?

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.

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.

As part of a focus we are putting on improving the speed of ingestion of FHIR payloads, in v2026.2 (available as of now as a Developer Preview), we are introducing an option to skip structure validation of resources. This could save for example 25% of the time, which in large scale ingestions, could be significant.

Has AI changed the way you learn and solve technical problems?

Do you still read technical blogs and community articles? If yes, which ones are still worth reading today?

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.

We have some exciting news to share! 🎉

Hi all,
I've been researching the capability within IRIS for Health OAuth2 machine-to-machine authentication. IRIS is the client in this case. 
Specifically, the idea is to build JWT claims, sign with a private key and then send a POST request as a client assertion to receive a bearer token. The bearer token would then be used in a subsequent request.
I've learnt one way to do this (described below) . Leaving out any concern about attaching the client_assertion, token caching etc. and focusing on just creating a signed-JWT.

Hi Community,

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.

Hi Community,

We're excited to invite you to the upcoming webinar in German: 

👉 InterSystems TechTalk #17 | ChatFHIR: FHIR Access with MCP and AI Hub 👈

🗓️ Date & Time: Wednesday, June 17th, 11 am CEST 

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.

I'm running a shell script and the q isn't exiting the screen. this is RHEL 7.9  I used to issue in VMS just fine but we have found that Linux scripts behave different.  after these run I search the file for the status and depending on what it comes back with it will send an email.

if someone has anything better I'm listening 

thanks

Paul

Every clinic visit starts the same way: a patient sits in a waiting room holding a clipboard, answering the same questions they'll be asked again ten minutes later — while the clinician walks in cold, with no idea whether the next case is a sore throat or a heart attack in progress.

That gap: between what the patient knows and what the clinician sees — is what Triage Park closes. It's our entry for the InterSystems Programming Contest: AI Agents for FHIR.

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

Using the SOAP wizard many moons ago, I had setup a process to get Patient Demographics, and the current Visit Location from Epic for processing HL7 DFT Charge Messages.

Within the past week we have had two cases where the Outbound SOAP Adapter has been throwing Errors (Exceptions) where in this case 

NO-PATIENT-FOUND details: No patient found with the provided ID and ID type.

The error is not being sent back in the Response to the Business Process that sent the call. The Response comes back blank.

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?

Hi all,

I'm looking for some advice on a DTL issue.

I'm working on an HL7 DTL where I need to populate MSH-6 / Receiving Facility using a combination of literal text and values from the PD1 Patient Primary Care Provider field.

The required MSH-6 value needs to be something like:

MCNIMCNumber.PracticeID

Where:

• MCN is a literal string
• IMCNumber comes from PD1
• PracticeID comes from PD1

For the IMC number, the direct source path that works is:

source.{PIDgrpgrp().PIDgrp.PD1(3).assigningauthority.namespaceID}

If I assign this direct path straight into MSH-6, the value populates.

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.

We are happy to present the bonuses page for the applications submitted to the InterSystems Programming Contest: AI Agents for FHIR

See the results below.

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.

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.
