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 )

Mr.

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.

Hi,
I'm pretty sure I'm not the first one to encounter this, so please share your solution
I'm trying to load a package with 2 dependencies, one of them has 5 dependencies..
is there a better tool / script / wizard for that?

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!

Welcome to Issue #27 of the InterSystems Ideas newsletter! Let's look at the latest news from the Ideas Portal, such as:

✓ General Statistics
✓ New sweepstakes!
✓ Recently implemented ideas by InterSystems

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?

Hi Community,

We're super excited to share that we launched another free, interactive tutorial designed to give you a little taste of InterSystems Data Studio.

🧑‍🏫 Introduction to InterSystems Data Studio 🧑‍💻

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.

Hello Community!

We're pleased to invite you to the upcoming webinar in Hebrew:

👉Getting Started with OAuth 2.0 on InterSystems👈

📅 Date & time: March 25th, 3:00 PM IDT

I would like to understand the mechanism of "How data is written to the IRIS Database and in what sequence data is written to Journal, WIJ and IRIS database"

Is it possible to run a test case by classname instead of loading it from a directory?

I need to skip any directory loading completely since the directory with the source code does not exist.

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.

Hello,

I have problem to get working my web application in IIS. On apache just works fine.

I had an app in wwwroot called test, there is index.html file where is tag

I created a new repo called ipm-module-budget from https://github.com/intersystems-community/intersystems-iris-dev-template template.

I cloned the repo to an EC2 instance in AWS. When I try to build image, I see this error:

#8 22.09 [IRISAPP|ipm-module-budget] Reload START (/home/irisowner/dev/)Segmentation fault (core dumped) #8 ERROR: process "/bin/sh -c pip3 install -r requirements.txt && iris start IRIS && \tiris session IRIS < iris.scri pt && iris stop IRIS quietly" did not complete successfully: exit code: 139

Already included in SystemPerformance

There are nfs disk commands (including nfsiostat) included with SystemPerformance, but disabled by default. Enable them by running:

$$Enablenfs^SystemPerformance()

Doing so will add the following nfs commands, for example, on Linux:

1. /usr/sbin/nfsstat -cn
2. /usr/sbin/nfsiostat [interval] [count]

Ensure the commands are installed and runnable from the OS :)

This can be subsequently disabled via $$Disablenfs^SystemPerformance()

Adding a generic command to SystemPerformance

Adding an arbitrary OS tool creates a "user" command under ^IRIS.

Issue

In the versions specified above, an instance may fail to start or may hang during operation if the database cache is greater than or equal to 2,097,152 MB (2 TB).

I have an issue and can't seem to find the problem.

Issue

 In some namespaces i get a 403 Page not Found error for healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.namespaceSelect.cls ; healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.finderDialog.zen  && healthconnect/csp/healthshare/[NAMESPACE]/_CSP.UI.Portal.About.zen

Iris setup

It is currently configured in a mirror group and on the other mirror-member i don't encounter the issue. (I have checked if it was because of the member-type Primary and Backup). 

The user that I am using has the %All role.

Hi Community,

We're super excited to share that we’ve just launched a new free, interactive tutorial designed especially for those who are new to InterSystems IRIS and looking for a clear, practical introduction to its core concepts.

🧑‍🏫 Data Models of InterSystems IRIS 🧑‍💻

Hello all,

I have a EnsLib.HTTP.GenericMessage inbound from a webhook with a GC stream.

My router is defined as the following:

There are lessons we learned from developing and maintaining code for interoperability components within a healthcare institutional environment.

The plane is already flying

Be prepared to rebuild, improve, extend, and fix the plane mid-flight.
 

Maintenance windows for hospital systems are often very limited, with some required to be operational 24/7. While the critical health systems such as imaging modalities or registration kiosks — or at least their critical functions — must operate autonomously, efficiency and usability may be compromised when interoperability components malfunction.

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

Hi community,

I've been working on a side project that I'd love to get some eyes on: a ground-up rebuild of the classic IRIS Production Monitor using a modern web stack. The existing ZEN/CSP-based portal does the job, but I wanted to explore what a contemporary, real-time version of it could look like.

What it is

A standalone Angular web application that connects to any Interoperability-enabled IRIS namespace and gives you a live view of your production — services, processes, operations, queues, event log, and message traffic — all in one screen.
