As mentioned in the previous article, it is possible to configure the way you wish your collections to be stored and queried in SQL.

To set this up, you will need to use the following field parameters and settings:
In InterSystems IRIS, when you compile a persistent class, you automatically get a SQL table. Sometimes, there are situations that require having a slightly (or not so slightly) different names/options in SQL compared to Object model. Here are some of the settings that you can change to make it happen.
Class-level settings
They define the "Face" of your class when it appears as a table in the SQL catalog.
SqlTableName allows you to change the name of SQL table that holds objects from your class. This is especially useful, when your class name uses reserved SQL words in a name, e.g. Group.
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.

This article introduces SHAP explainability methods as an approach to understand the reasons behind predictions in machine learning black-box models. It also includes a simple Jupyter notebook that you can use and modify to gain hands-on experience with these concepts:

When managing critical healthcare data through an integration engine you want to know the moment a queue starts backing up or a service drops.
Unfortunately, this usually leads to an email inbox stuffed full of notifications that can sometimes seem impossible to maintain.
Well, I’ve not solved that problem.
But I have created something that could help...

As an experiment in agentic coding in ObjectScript I'm using VS Code to try and create an implementation of an SFTP server.
SFTP is built on top of SSH, so the first phase involves implementing an SSH server. While working on the KEX part of that the agent (using GPT-5.3-Codex) reported:
- IRIS has what we already need for signing and hashing: RSASHASign, RSASHAVerify, RSAGetLastError, SHAHash, SHA1Hash, SHA3Hash.
- It does not list a Diffie-Hellman key exchange or modular exponentiation API in %SYSTEM.Encryption.
It then offered these options:
- Keep using IRIS APIs for cert/key/sign/hash.
Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)
NAMING THINGS RANDOMLY
We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare.
➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.
I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.
1. Getting lost among system classes and where to start
The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

Welcome to the next chapter of my CI/CD series, where we discuss possible approaches toward software development with InterSystems technologies and GitLab.
Today I want to share a few approaches that will decrease your compilation time (especially if you're doing incremental/diff compilation rather than a full build).
Compiler flags and qualifiers
Code load and compilation are affected by a variety of flags and qualifiers. If you write deployment scripts for InterSystems platforms, I highly recommend reading them at least once through.
Hi Community!
We have another great initiative for you to sink your teeth into! Following last year's resounding success, we're hosting a new edition of the Demo Games. But with a twist: our North American Sales Engineers have submitted their best demo videos, but this time, you're the ones to take part and win a prize.
Please welcome the North American Demo Showcase! 🎉

Below is an update to the IRIS release calendar for 2026 and an early look at the planned changes for 2027. The key takeaway for 2026 is that maintenance release numbering will differ slightly from prior years.
2026: IRIS 2026.1 maintenance release numbering
- July 2026: first maintenance release for IRIS 2026.1 (planned version: 2026.1.4)
- October 2026: next maintenance release (planned version: 2026.1.5)
- February 2027: following maintenance release (planned version: 2026.1.6)
This numbering change prepares us for the expanded maintenance cadence planned for 2027.

Hello and welcome to the April 2026 Developer Community YouTube Recap.
Every great community is enriched by those who work tirelessly behind the scenes, crafting the knowledge and resources that help others grow. In the InterSystems Developer Community, one such person is @Derek Robinson — a dedicated educator, whose passion for teaching has helped shape how developers everywhere learn to work with InterSystems technologies.
👏 Let's take a closer look at Derek's journey in the InterSystems ecosystem.

I am working on setting up OAUTH with FHIR and Microsoft Entra. I have configured the Client and configured it in the FHIR Server successfully. However, I get 401 when authenticating with a token. Looking at ^ISCLOG I see:
^ISCLOG("Data",9,0)="accessToken=<jwt token>, scope=, aud="
^ISCLOG("Data",10)=$lb(3,"OAuth2","[OAuth2.ServerDefinition:ValidateJWT]","171430","%SYS","2026-04-28 17:41:25.305549397","OAuth2.ServerDefinition.1","","zwKKakZZZx2")

We have a large, existing production taking a feed from a single up-stream system and sending to a wide-variety of downstream systems. One of the downstream systems has been decommissioned, and we have deleted the classes that implemented the routing/transformations from the namespace, and deleted the components from the production (Wardview and WV Out in the diagram below). We now want to delete the messages associated with those components without deleting the messages associated with any other components.

Ever since I started using IRIS, I have wondered if we could create agents on IRIS. It seemed obvious: we have an Interoperability GUI that can trace messages, we have an underlying object database that can store SQL, Vectors and even Base64 images. We currently have a Python SDK that allows us to interface with the platform using Python, but not particularly optimized for developing agentic workflows. This was my attempt to create a Python SDK that can leverage several parts of IRIS to support development of agentic systems.
What's a good way to add a custom hyperlink to a table item in Clinical Viewer (CV2)? I am customizing the Diagnostic Studies page, and have a custom transform that returns the HTML code for the hyperlink. The hyperlink is supposed to open a custom CSP page in a new window or tab.
Using the layout editor, I then tried adding several "items" to the table like an Icon or External Viewer Link, and use the custom transform to get the hyperlink, but these items only show up as plain text and do not link to any page. How do I turn these items into a hyperlink?
One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.
If you are looking for high availability you could use:
a) Kong Traditional Mode: Multiple Node Clusters
b) Hybrid Mode
c) DB-less Mode
Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.
