IRIS can use a KMS (Key Managment Service) as of release 2023.3.  Intersystems documentation is a good resource on KMS implementation but does not go into details of the KMS set up on the system, nor provide an easily followable example of how one might set this up for basic testing.

The purpose of this article is to supplement the docs with a brief explanation of KMS, an example of its use in IRIS, and notes for setup of a testing system on AWS EC2 RedHat Linux system using the AWS KMS.  It is assumed in this document that the reader/implementor already has access/knowledge to set up an AWS EC2 Linux system running IRIS (2023.3 or later), and that they have proper authority to access the AWS KMS and AWS IAM (for creating roles and polices), or that they will be able to get this access either on their own or via their organizations Security contact in charge of their AWS access.

Hi,

I want to consume an API that provides HL7 messages. To achieve this, I have thought of the following workflow:

I have created a business service that periodically triggers a business process. The trigger request is forwarded to a business operation. There, a %Net.HttpRequest is assembled from scratch and then sent to the API endpoint. The corresponding HttpResponse then contains several HL7 messages encoded in UTF-8 in the message body. To further process the HL7 messages, the operation sends the HttpResponse back to the business process as EnsLib.HTTP.GenericMessage.

TL;DR This article explains how to deploy InterSystems IRIS Community Edition on Azure using the Azure Marketplace and a Virtual Machine. It covers prerequisites, instance selection, authentication, SSH access, first verification steps, and how to delete resources to avoid charges. The deployment can typically be done using Azure free credits and is suitable for developers who want to quickly start working with IRIS in the cloud.

Who this guide is for. This guide is intended for developers, solution architects, and DevOps engineers who want to deploy InterSystems IRIS Community Edition on Microsoft Azure. No prior Azure automation experience is required, but basic familiarity with the Azure Portal and SSH is helpful.

After following this guide, you will be able to:

• Launch InterSystems IRIS Community Edition from the Azure Marketplace
• Configure a small, secure Azure VM
• Connect to IRIS using SSH and the Management Portal
• Reset the default IRIS password and verify that IRIS is running

Prerequisites

• An active Azure subscription (new accounts may have free credits)
• Permissions to create resource groups, VMs, and networking resources
• An SSH client and a private key (.pem) you can store securely
• Basic knowledge of Linux command line

Deployment overview

• Open the IRIS Community Edition listing in Azure Marketplace and click Get it now
• In Azure Portal, choose Start with a pre-set configuration (or Create)
• Configure Basics: subscription, resource group, VM name, region, image, and size (a small VM is usually sufficient)
• Choose SSH key authentication and generate/download the key if needed
• Review + Create, accept terms, and deploy; then Go to resource → Connect → SSH
• First SSH login: run iris password to change _SYSTEM/SYS; start a session with iris session iris
• Management Portal: http://YOUR_VM_IP:52773/csp/sys/UtilHome.csp

If you work with Productions, highlighting connections between Business Hosts is a very convenient feature, allowing developers to get a visual representation of a data flow.

This feature works by default with all system Business Hosts. If a user writes their own Business Services, Processes, or Operations, they must implement the OnGetConnections method for this functionality to work with their custom Business Hosts (or use Ens.DataType.ConfigName properties for connections).
That said, the SMP shows only the first layer of connections of the selected Business Host. Sometimes, we need to get connections of connections recursively to build a complete data flow graph. Or we might need this connection information to check which downstream systems might be affected by a change upstream.

Enabling HSSYS Mirroring Out of the Gate with IKO

For those of us building InterSystems workloads on Kubernetes, we are definitely spoiled with the InterSystems Kubernetes Operator (IKO) doing the heavy lifting and mirroring on day one.  Where us spoiled brats jump up and down is when we try to add additional databases/namespaces when we provision from HealthConnect containers on day two, while others get to utilize HealthShare Mirroring for this task, the prerequisite of mirroring HSSYS out of the gate has been somewhat elusive.  Here is example on how you can this powerful feature up and running with the employment of IKO and IrisClusters.

PEP 578 added Python Audit hooks. A rich variety of events (module load, os interactions and so on) triggers audit events which you can subscribe to.

Here's how to do that. First create an embedded python hook:

Class User.Python
{

/// do ##class(User.Python).Audit()ClassMethod Audit() [ Language = python ]
{
import sys
import time
def logger(event,args):
     if event=='import':
        module = args[0]
        print(f"Loading {module}")
        if module == "numpy":
            print(f"Module {module} forbidden. Terminating process in 3.")
            time.sleep(3)

Hello everyone,

My team lead mentioned that users can sometimes create globals directly without associating them with tables or classes. In this case, these globals would not be accessible via SQL.

Is this correct? Can a global exist independently in this way, and if so, is there a specific approach to access or manage them without SQL?

10:47 AM — Jose Garcia's creatinine test results arrive at the hospital FHIR server. 2.1 mg/dL — a 35% increase from last month.

What happens next?

• Most systems: ❌ The result sits in a queue until a clinician reviews it manually — hours or days later.
• This system: 👍 An AI agent evaluates the trend, consults clinical guidelines, and generates evidence-based recommendations — in seconds, automatically.

No chatbot. No manual prompts. No black-box reasoning.

This is event-driven clinical decision support with full explainability:

✅ Triggered automatically by FHIR events ✅ Multi-agent reasoning (context, guidelines, recommendations) ✅ Complete audit trail in SQL (every decision, every evidence source) ✅ FHIR-native outputs (DiagnosticReport published to server)

Built with:

• InterSystems IRIS for Health — Orchestration, FHIR, persistence, vector search
• CrewAI — Multi-agent framework for structured reasoning

You'll learn: 🖋️ How to orchestrate agentic AI workflows within production-grade interoperability systems — and why explainability matters more than accuracy alone.

Who hasn't been developing a beautiful example using a Docker IRIS image and had the image generation process fail in the Dockerfile because the license under which the image was created doesn't contain certain privileges?

In my case, what I was deploying in Docker is a small application that uses the Vector data type. With the Community version, this isn't a problem because it already includes Vector Search and vector storage. However, when I changed the IRIS image to a conventional IRIS (the latest-cd), I found that when I built the image, including the classes it had generated, it returned this error:

In Part 1, we laid the technical foundation of MAIS (Multi-Agent Interoperability Systems). We have successfully wired up the 'Brain', built a robust Adapter using LiteLLM, locked down our API keys with IRIS Credentials, and finally cracked the trick code on the Python interoperability puzzle.

Today, in Part 2, we will define the Anatomy of an Agent. We will move from simple API calls to structured Personas. We will learn how to wrap the LLM in a layer of business logic, giving it a name, a

Hi everyone, 

Does anyone know how to export projects via VSC? 

I opened the project through the "InterSystems Tools" plugin (command is "Edit Code in Project") and I can correctly work on it.

However, when I try using the "ObjectScript" plugin to export the project (right click on the project -> "Export Project Contents")

This message appears and it is not possible to export the project:

I've tried also to open a new window, then a folder and finally the project, but nothing changes. 

This is an example of my workspace: 

Anyone knows how to do it? 

Thank you!

As applications grow, every database eventually hits scaling limits. Whether it's storage capacity, concurrent users, query throughput, or I/O bandwidth, single-server architectures have inherent constraints. This guide explains fundamental approaches to database scalability and shows how InterSystems IRIS implements these patterns to support enterprise-scale workloads.

We'll explore two complementary scaling strategies: horizontal scaling for user volume (distributing computational load) and sharding for data volume (partitioning datasets). Understanding the general principles behind these approaches will help you make informed decisions about when and how to scale your IRIS applications.

The examples in this guide use InterSystems IRIS in Docker containers.
