Is there any dedicated place on the InterSystems site to complain about "Ask DC AI" lack of rather simple knowledge? I'd say, as a bare minimum it should be trained on ALL InterSystems usually excellent documentation and know how to quote from it. A couple of recent examples, all of them "beyond my knowledge", which really should not be "beyond my knowledge". Common language rephrasing did help with a couple of requests below, but AI should be able to rephrase itself.

* iris-certified-agents are not actually certified in anything

Studying for an InterSystems certification?  Eliminated your entire staff and need to make good on your commitment to AI to support your workload? New to InterSystems products or building your startup on InterSystems technologies?  Onboard these intersystems agents compatible with your model and agentic IDE of choice and speak InterSystems technologies like a protocol droid.

Quick Start  

So if you just want to cut to the chase, got get your agents @ https://github.com/sween/iris-certified-agents

Hi Community, 

If you’re new to InterSystems, check out the InterSystems Developer Hub.

Start working with InterSystems technologies — install InterSystems IRIS, connect to it, run something real, or try products directly in a browser-based interactive environment (no setup required).

If you’re wondering where to begin, here’s what you’ll find there:

⏯️ Message Operational Data Store

Create an operational data store using the data flowing through your production. Create user-defined analytics tables based on fields and paths to their data from incoming documents with varying standards (FHIR, CDA, HL7v2, etc.).

Hey Community,

We’re launching a new initiative in which ideas from the Ideas Portal become real applications on Open Exchange, and their authors are rewarded through Global Masters:

💡 Community Bounty Program “Idea to Application” ⚙️

The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS^® for Health, and HealthShare^® Health Connect is now Generally Available (GA). This is an Extended Maintenance (EM) release.

Hi Community,

Take a look at these new videos in online learning, and get familiar with new features and interfaces in the latest release of InterSystems® products. All videos are also available in the Learning Services YouTube channel.

Plus, check out a video for new ObjectScript developers, and a guide for HealthShare® users upgrading their deployments.

• Goal: Learn about enhancements to the interoperability UI in version 2026.1 of InterSystems products.

I created a persistent class with all the associated classmethods that will be needed. I am going to use it as a temp storage for data.

Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File. 

We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.

Thanks

Scott

Hi, Community!

Are you working with large tables? See how partitioning helps you manage and query your data:

Managing Tables with Partitioning in InterSystems IRIS

I have a daily service that consumes x number of files, each file name chronologically suffixed sequentially by _1, _2, etc. I only want to process the latest file.

How do I build a business rule so it will only process the last file?

Today I have published a new Open Exchange package for generation of Synthetic Data directly into IRIS.

 It can be a frustrating process to find decent datasets when you are looking to make a demo app. Maybe the dataset doesn't matter that much, but you still want it to appear somewhat genuine and with several linked tables that are usable directly within IRIS with the neat implicit joins with ->. Maybe you just want linked tables that are easily installable with IPM to benchmark queries, this dataset generation would be perfect.

Hi Community!

Thank you to everyone who participated in the "Suggest topics for our next free hands-on tutorials" sweepstakes! Your ideas and suggestions are invaluable and will definitely influence our tutorials roadmap! 

Now, it's time to announce the winner – watch the video to see the sweepstake drawing:

Table Partitioning Demo

This demo walks you through the new Table Partitioning feature in IRIS SQL, explaining what it does and how it works along the way. We'll only use a few dozen rows to prove the concept, but obviously the capability is focused on datasets many orders of magnitude larger.

If you'd like a shorter, higher-level introduction to Table Partitioning, check out the online learning module Managing Tables with Partitioning in InterSystems IRIS

ℹ️ Table Partitioning is included in IRIS 2026.1 as an experimental feature

In last post I talked about iris-copilot, an apparent vision that in near future any human language is a programming language for any machines, systems or products. Its agent runners were actually using such so-called 3rd generation of agents. I want to keep/share a detailed note on what it is, for my own convenience as well. It was mentioned a lot times in recent conversations that I was in, so probably worth a note.

Hey Community!

We're happy to share the next video in the "Code to Care" series on our InterSystems Developers YouTube:

⏯ MCP Explained: Bridging the Gap between AI Agents and Tools

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.

⏯️ AI-Assisted Rare and Complex Disease Detection

This demo shows how InterSystems Health Gateway can be used to pull in outside patient records from networks like Carequality, CommonWell, and eHealth Exchange, creating a more complete longitudinal view in a clinical viewer. That full record is then analyzed by AI to surface potential rare disease considerations with clear reasoning, helping clinicians see patterns they might otherwise miss.

I am connecting to an intersystems cache database via C# and I need to obtain a list of all available namespaces.

I am using code like this:

The George James Software team is looking forward to going to National Harbor for READY 2026!

As part of the conference, we'll be hosting our Deltanji Source Control User Group:

Date: Wednesday, April 29th 
Time: 8 - 9am (breakfast will be provided) 
Location: Azalea 1 
RSVP by emailing laurelj@georgejames.com. 

We'll be showing what will be included in the next release of Deltanji, version 8.2, as well as providing an opportunity for questions and discussion. We welcome both current and prospective users to join us.

The Management Portal doesn't have a native way to switch to Dark Mode. This can be resolved using a Chrome extension called Dark Reader. See the result:

To install and use the Dark Reader:

I'm starting to play more with AI enabled coding. 
I've been using Github Copilot inside Visual studio code, which is very good at coming up with autocomplete suggestions that are accurate and useful. (Along with some utter rubbish, naturally).
For web development I'm starting to use Claude Code in VS Code to help create web sites and integrations. I want to see how it can help with IRIS development. 

However I can't get claude to read any iris code directly as I'm connected to my server via isfs server connections.

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.
