The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS^® for Health^TM, and HealthShare^® Health Connect is now Generally Available (GA). This is an Extended Maintenance (EM) release.

Release Highlights:

• Database Scalability Enhancements: Historical database size limits have been removed, enabling seamless growth beyond prior size constraints with no data conversion required. Additional low-level performance improvements further optimize large-scale operations.

The Interoperability user interface project has continued from 2025.1 and has incorporated many of the items that you – our customers and partners – have suggested and observed.  We are continuing to invest in feedback and updating this important user experience.  In the latest release, 2026.1 for IRIS, IRIS for Health, Health Connect and Health Connect Cloud, the BPL Editor and Message Viewer/Visual Trace applications are now available for opt-in!
NOTE:

• Existing users can switch between the modernized and standard experiences.

Despite the fact that LOCK (docs) is a foundational part of InterSystems IRIS, responsible for concurrency, there is not a lot of discussion on the Developer Community about it. Which is understandable, considering it's stable and fairly low-level command. In this article, I will show a simple example of how to use locks with interoperability.

Hey Community!

Have you attended one of the Global Summits or a previous READY 2025? We’d love your help to inspire others to join InterSystems READY 2026!

Hi!
We are deploying the iris image in a Kubernetes environment and the cluster state is "Hung" , looking the alerts endpoint we get 2 alerts:

Any idea / help where those are comming from and how to address them?

Introduction — The Problem with AI Streaming in ObjectScript

Today, I would like to introduce a problem I encountered and the solution I found when integrating AI APIs into an ObjectScript application. My initial tests were successful, yet somewhat frustrating.

The HTTP call worked; the request was properly sent to my LLM APIs. But then, silence... a long wait. Eventually, the entire response arrived as a single block.

Technically, it worked, but the user experience was disappointing compared to a ChatGPT session.

Modern models are designed to stream their output token by

Hi Communtiy,
I am a begineer who is working and trying to understand Intersystems. I am developing an Ensemble interface which receives a XML message and converts it into HL7 format without using enslib.HL7 classes. 
Requirement

1. My file consists of patient details which needs to be updated in a sql table whenever the same patient arrives. We need to check if the patient exists and convert it into a pId segment.
2.

SetUp:

I have created the following Task to kick off a Ens.BusinessService to execute a SQL query and process the results

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition
{

Parameter TaskName As STRING = "OSU - Workday Termination Update";

Method OnTask() As %Status
{
    #Dim sc as %Status
    #Dim ex as %Exception.AbstractException
    
    set sc = $$$OK

    try{
        // create the service
        #Dim tService As OSU.DataSource.Workday.TermService
        Set tServiceConfigName = "OSU.DataSource.Workday.

Hi Community!

We’re building a series of short, hands-on Instruqt tutorials to help newcomers get up to speed with InterSystems technologies faster and more effectively. To kick things off, we’ve just released a new tutorial, “Data Models of InterSystems IRIS,” covering the fundamentals of the IRIS multimodel approach. This is exactly the type of focused, concise, practical learning experience we want to expand. And this is where you come in!

We’d love to hear your ideas for other tutorial topics to help developers new to InterSystems IRIS take their first steps with confidence.

Hello, I am working with @Alberto Fuentes https://openexchange.intersystems.com/package/workshop-iris-oauth2.

I wonder how do I get a token to send to the resserver?

I tried calling "token_endpoint" : "https://webserver/authserver/oauth2/token"

The response was "error":"invalid_request","error_description":"Unknown grant_type"

I wonder what needs to be in the request body? Is it a GET or POST?

Let’s see who can make READY 2026 impossible to resist.

We are trying to run the HS solution inside of a container, but we are getting the following errors un start up
03/17/26-10:19:05:108 (1386) 1 [Generic.Event] Cannot lock /usr/irissys/mgr/hslib/ err(13): will try accessing readonly
03/17/26-10:19:08:174 (1386) 1 [Generic.Event] Cannot lock /usr/irissys/mgr/enslib/ err(13): will try accessing readonly

I understand that those databases should be mounted as read only don't needing the lock, any idea how to fix it? or where should I look to configure it correctly?
Thanks!

As you all probably know, Health Connect / IRIS for Health natively supports DICOM messaging, and many of you will have used it daily. Well, I recently discovered a rather insidious little issue that our beloved @Alberto Fuentes gave me the solution.

We (I) will call this phenomenon the Creosote effect (those of you who know Monty Python will understand the reference, for the rest you can see the sketch here )
