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.

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

• %-variables (process variables). Reusing only in the same process
• Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

• Using Interoperability Production.

Hello, community.

I've been working with Intersystem Caché for two years, and right away I was excited about the rich ecosystem that Caché provides. However, I was disappointed with calls using #call, and I understand that it was a limitation of the time. Well, the frustration is that #call returns null by default, meaning an AJAX request is executed, but there's no hook to retrieve the return from that request. The only way to retrieve the data from that request is by building a callback on the server side using &js<>.

What is a Microservice?

A microservice is an architectural style that structures an application as a collection of small, autonomous services. Each component is developed around a specific business capability, can be deployed independently, and is typically managed by a miniature, specialized, self-governing team. (Source: https://microservices.io/)

During my work with customers and also following I often met the 
explicit or embedded question: What is this "GLOBALS" ?
I'll try to explain the history to unfold the context.

Has anyone done this successfully?  Customer wants to receive HL7 data over https using OAUTH 2.0 client credentials.  I am assuming a custom Operation will be needed?  I tried using CoPilot for assistance but was unsuccessful.  I am not great with Object script :( 

Introduction
InterSystems IRIS Adaptive Analytics is an optional extension that provides a business-oriented, virtual data model layer between InterSystems IRIS and popular Business Intelligence (BI) and Artificial Intelligence (AI) client tools. Adaptive Analytics is powered by AtScale, the AtScale documentation can be found at this link: https://documentation.intersystems.atscale.com

This article will showcase some AtScale features that can facilitate data analysis:

1. Cube creation
2. Excel visualization
3. Parallel Period
4. Queries
5. Snowflake
6. Security

7. Aggregates

The 2025.1.4 and 2024.1.6 maintenance releases of InterSystems IRIS^® data platform, InterSystems IRIS^® for Health, and InterSystemsHealth Connect™ are now Generally Available (GA). These releases include the fixes for a number of recently issued alerts and advisories, including the following: 

• April 15, 2026 – Alert: Removal of InterSystems IRIS for Health and Health Connect 2024.1.4 and 2024.1.5 Due to Health Interoperability Issues | IDC

Before finding the best solution for Supply Chain, we need to understand what Supply Chain is. Well, regardless of the language used, the term is known by the name already mentioned. For your information, the translation in Brazilian Portuguese is "Cadeia de Suprimentos" (Supply Chain), sometimes also called "Cadeia Logística" (Logistics Chain), but we will not dwell on the nomenclature, but rather on the meaning.

Hi, every one. Again, it's me!!😀😀

Recently I was trying to organize some learning materials for InterSystems IRIS😆, and realized that the resources are actually quite scattered.🤐

So I put together a list here—grouped by categories—for anyone who:

• is new to InterSystems
• or wants to go deeper into specific areas

Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).

1. For starters

If you don’t know where to begin, start here:

• https://developer.intersystems.com/
• https://developer.intersystems.com/resources/
• https://developer.intersystems.com/intersystems-iris-getting-started/

Over the past year there have been a few DC articles offering MCP servers designed to connect to IRIS and help the AI features of VS Code and its cousins do a better job. For example:

• Hey chat, what's up with my Interoperability by @Dmitry Maslennikov 
• No-Hallucinate MCP: Real-time Routine Context for ObjectScript by @Jinyao 
• iris-mcp-atelier introduced by @Ernest Salas in his comment on the post by @Mark Charlton

I use cspa24.so Apache module to connect to IRIS. I have notified that idle Apache processes will always result in connections being kept open to the IRIS server, and thus some amount of IRIS processes being kept alive (and dedicated to those apache processes) because of those connections.

Eg: if I have 50 idle Apache processes, I will have 50 IRIS processes being kept alive in IRIS even if there is no client connection being made at that time. 

It's even worse with multiple Apache nodes and a load balancer.

This past weekend we ran into something odd. When we failed over our mirror from 2022.1.3 to 2025.1.3 the one of the Business Rules that was on what became the Primary (2025.1.3), had a rule within it that was removed back in January. When the Failover occurred, we had to scramble to backup, disable, and remove the Rule that shouldn't have been there. 

Both the Data and Code live within the same IRIS.dat that is the main MIRROR database for that Namespace. 

If this happened to one Class file, could it happen to others we do not know about?

Motivation

Why do we need this?

1. Lack of Compiled Context: AI tools only see source code; they don't know what the final compiled routine looks like.

2. Macro Hallucination: Because AI doesn't see our #include files or system macros, it often makes them up, wasting time during debugging.

3. The Documentation Gap: Deep logic optimization often requires understanding internal macros that aren't fully covered in public documentation.

4. Manual Overhead: Currently, the only way to fix this is to manually use the IRIS VS Code extension to find the "truth" in the routine.

The PACELC theorem was created by Daniel Abadi (University of Maryland, College Park) in 2010 as an extension of the CAP theorem (created by Eric Brewer - Consistency, Availability, and Partition Tolerance). Both help design how to architect the most suitable operation of data platforms in distributed environments under the aspects of consistency versus availability. The difference is that PACELC also allows analysis of the best option for non-distributed environments, making it the gold standard for considering all possible scenarios to define your deployment topology and architecture.

The CAP theorem states that in distributed systems, it is not possible to have consistency, availability, and partition tolerance simultaneously, requiring a choice of two out of three, according to the following diagram.
