Hi Community,
A big perk of attending InterSystems READY 2026 (April 27–30) is the chance to talk to experts like @Sam Schafer!
Are you familiar with SQL databases, but not familiar with IRIS? Then read on...
About a year ago I joined InterSystems, and that is how IRIS got on my radar. I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew. However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better. With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc. I hope I can make things clearer and simpler for you and save you some time getting started.
SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.
The Problem: Dynamic SQL and SQL Injection
Dynamic SQL constructs queries as strings at runtime. While this offers flexibility, it also creates a vulnerability if user input is not handled correctly.

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.

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!

Hi Community,
In this article, I will introduce my application iris-HL7v2Gen .
IRIS-HL7v2Gen is a CSP application that facilitates the dynamic generation of HL7 test messages. This process is essential for testing, debugging, and integrating healthcare data systems. The application allows users to generate a wide variety of HL7 message types, validate their structure against HL7 specifications, explore the message hierarchy, and transmit messages over TCP/IP to production systems. These features are particularly useful in settings where compliance with HL7 standards is mandatory for interoperability between different healthcare organizations or systems.

Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.
What Changed
Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.

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.
Hello InterSystems Community,
I hope you're all doing well. I'm reaching out to ask if there's any way to enable a dark theme or dark mode for the HealthShare Management Portal.
Background
I have a visual impairment (amblyopia/lazy eye) which means I'm nearly blind in one eye. Like many people with visual difficulties, I find that bright white backgrounds and interfaces cause significant eye strain and fatigue. This makes it challenging to work with the Management Portal for extended periods.
Introduction
Earlier this year, I set about creating kit to introduce young techy folk at a Health Tech hackathon to using InterSystems IRIS for health, particularly focusing on using FHIR and vector search.
I wanted to publish this to the developer community because the tutorials included in the kit make a great introduction to using FHIR and to building a basic RAG system in IRIS.

I may have mentioned this before: I believe the Visual Traces, these sequence diagrams with full content of each step, are a fantastic feature of the IRIS Data platform! Detailed information about how the API works internally, as a visual trace, can be very useful for projects on the IRIS platform. Of course, this applies when we are not developing a high-load solution, in which case we simply don't have time for saving/reading messages. For all other cases, welcome to this tutorial!
In this article I'll show you how to set up in your laptop, very quickly, a cluster of IRIS nodes in sharding. It's not the goal of this article neither to talk about sharding in detail nor define a deployment of a production ready architecture, but to show how to set up quickly, in your own machine, a cluster of IRIS instances configured as shard nodes, with which you'll able to play and test this functionality. If you're insterested in knowing more about sharding in IRIS, take a look at the documentation clicking here.
First and foremost, I want to remark that IRIS sharding will allow us 2 things:
- Define, load and query shard tables, which data will be distributed transparently between the cluster's nodes
- Define federated tables, which offer a global and composed view of data belonging to different tables that will be physically stored in different distributed nodes
So, as I said, we let for other article playing with shard or federated tables, and just focus now in the previous step, that is, setting up the cluster of shard nodes.

If you have ever dug through a large IRIS namespace looking for where a particular string, method call, or pattern was used, you know the pain: there was no built-in way to do a grep-style search across your server-side ObjectScript code from VS Code — at least not without jumping through some hoops.
That is what ObjectScript Search fixes.
Try it today with a simple install from the VS Code Marketplace. If you don't like it, uninstalling is just as easy. But I think you will like it — it is a huge quality-of-life improvement for anyone doing ObjectScript development in VS Code.

We are trying to track down significant growth within our Namespaces, one big culprit is Ens.AppData (EnsLib.SQL.Snapshot).
Within many of our BPL's we use EnsLib.SQL.Snapshot to return Results from External SQL Stored Procedures or Query's. The same EnsLib.SQL.Snapshot context variable is used for many of these calls within a BPL.
Is there something we should be doing at the end of the BPL to ensure that EnsLib.SQL.Snapshot gets cleaned up and purged from Ens.AppData?
