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

Question Oliver Wilms · 3 hr ago

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?

Question Luis Gallardo · Mar 17

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 )

I created a table profile dashboard on Power BI, but I wonder if is possible to do it in Iris by creating a class.

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.

Hello to all the esteemed members of the InterSystems developer community in Spanish!

Although I often consult the developer community and have occasionally left a question here, this will be my first article, and what better occasion to do so than by participating in the 3rd technical article contest.

The topic I will cover in this article is the different tools that InterSystems IRIS provides us to optimize both the databases and the queries we run, as well as the new types of storage and data.

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.

Hi Community,

Out of almost 200 applications, 26 selected teams will begin a 3-month fully virtual journey at Caelestinus. The cohort brings together pre-seed to seed stage startups from across the globe, spanning the United States, South America, Europe, South Korea, and Singapore.  

During the program, teams will enhance their solutions by building in interoperability, gaining an understanding of key digital health standards, and transforming them using InterSystems IRIS for Health and FHIR Server with the help of InterSystems experts.

We're pleased to invite everyone to watch the Caelestinus 2026 Kickoff Event streaming, where you can discover which teams were selected and learn about their innovative ideas.

Please watch the streaming via www.caelestinus.tech starting at 9 AM ET / 2 PM CET on March 25th 2026.

You can also watch the recording of the opening event here.

 Hi everyone,

I’m currently working with InterSystems IRIS and handling large datasets where some queries are starting to take longer than expected.

So far, I’ve tried basic indexing and reviewing query structures, which helped a bit, but I still feel there is room for improvement. My goal is to reduce response time, especially for frequently used queries in a production environment.

While reviewing our Orphan messages, we noticed that there are some Orphans that look like they are the start of an HL7 message.

MSH|^~\&

Since this does not link to any Message Header, and most of the information in EnsLib_HL7.Message is NULL, is there a way to track down what Object maybe creating these so we can nip it in the bud.

Only way that I know of is to go through each of our Schema's and make both the MSH and Encoding Characters optional.
