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.

For example in %Library.File Class Documentation,  FiieSet query is listed as: 
"Selects Name As %String, Type As %String, Size As %BigInt, DateCreated As %TimeStamp, DateModified As %TimeStamp, ItemName As %Stringof ..."

How to obtain a "real" syntax?

Thank you.

Hi Guys,

I get a Quit argument not allowed error in an if block how can I fix this?

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.

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?

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 )

Hi Community,

Preparing for InterSystems Certification examsrequires more than reading documentation. It calls for focused practice aligned with real exam objectives.If you are planning to validate your expertise in HL7, SQL, System Administration, or Development, structured preparation can make a significant difference.

The problem

How many times have we migrated an IRIS Instance to another machine, maybe even another version, and after a few days realized we forgot that one SSL Configuration critical for a Business Operations to work? Or maybe a credential, or a lonely class in a package by itself?

The solution

The simple solution is to make a checklist¹. A checklist of the entities we have to move. But simple checklists on Word documents are often forgotten, or just ignored.

I have a json object coming in on a service with a field that has "NaN" as its value.

"ReferralInOutOfNetworkCd": "NaN",

In my DTL, I do a straight copy. yet what goes outbound is NaN, without being wrapped in double quotes

"consulting_provider_network_ordering_rd":NaN,

Has anyone experience this?  If so, did you find a way to fix or work around it?
