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:
Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).
If you don’t know where to begin, start here:
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:
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?
READY 2026 is almost here, and we’re really curious to hear what everyone is looking forward to this year 🚀
What are you most excited about? It could be a topic you want to explore, a question you’re hoping to get answered or something you’re simply curious about.
Share your thoughts below! We’d love to hear what’s on your mind and see what others are excited about too 💬
Feel free to read through the replies and like the ones you relate to! 😊
Why do we need this?
Lack of Compiled Context: AI tools only see source code; they don't know what the final compiled routine looks like.
Macro Hallucination: Because AI doesn't see our #include files or system macros, it often makes them up, wasting time during debugging.
The Documentation Gap: Deep logic optimization often requires understanding internal macros that aren't fully covered in public documentation.
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.
Hi Community,
In our two preceding articles, we explored the fundamentals of the Interoperability Embedded Python (IoP) framework, including message handling, production setup, and Python-based business components.
In this third piece, we will examine advanced methodologies and practical patterns within the IoP framework that are pivotal for real-world interoperability implementations.
We will explore the following topics:
✅ DTL (Data Transformation Language) in IoP
✅ JSON Schema Support
✅ Effective Debugging Techniques
Collectively, these features help us create maintainable, validated, and easily troubleshootable production-grade interoperability solutions.
Hi Community,
We're excited to invite you to the next Community webinar presented by George James Software, an InterSystems partner:

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.

hi 😊,
i'm able to LOAD DATA in IRIS from a rather complex, say Oracle's, query. It works pretty well but requires a target table created aforehand:
LOAD DATA FROM JDBC CONNECTION SOME_OTHER_SERVER QUERY 'complex query here' INTO TargetTableis there a way to base such target table on the same query ?
CREATE FOREIGN TABLE seems to require a column definition which I would prefer to be taken from the query
CREATE TABLE AS SELECT seems to be for local queries and other methods, like Linked Table Wizard or %SYSTEM.SQL.Schema.
Hello,
I am working on integrating a CELL-DYN Ruby hematology analyzer (Abbott) with InterSystems Ensemble using the ASTM E1394 protocol over TCP/IP via a Digi One SP serial-to-TCP converter. I am facing a persistent issue where the Link Test keeps failing on the CDRuby side and the Transmit button remains greyed out. I have overridden EOTOptional=1 in the service class file as Ensemble was not able to send ACK after ENQ. Now I am getting below logs like Machine sends ENQ, Ensemble sends back ACK and Machine sends EOT instead of STX.

Hi everyone,
I was wondering if it is possible to use the InterSystems Server VSCode Extension to work in client side mode but importing locally the content of a project without having to choose the files manually.
It would be awesome to have all project-related assets synchronized in one go. Relying on InterSystems Projects (.prj files) would be convenient for several reasons:
Claude Code has a strong understanding of IRIS, but unexpected issues still occur.
The first issue is one that has already happened several times and is likely to continue occurring if not properly addressed.
In IRIS, the collation for string data (%String) is set to SQLUPPER by default. As a result, when data is retrieved via SQL, it may be returned in uppercase (for example, when sorting and aggregating with GROUP BY).

Hi, Community!
Need help setting up OAuth on the FHIR Server? We'll guide you through the workflow:
Since I started using Claude Code, my motivation to create things has skyrocketed.
Previously, even if I wanted to build something, actually doing the coding felt like a hassle, so unless there was a very strong need, I rarely went as far as programming. But now, if I just jot down the specifications, Claude Code handles the rest automatically, resulting in a dramatic improvement in productivity.
I come from a generation native to ObjectScript, so I used to feel some hesitation when it came to switching to Python.
The first quarter of the year was full of exciting activities in the InterSystems Developer Ecosystem. In case you missed something, we've prepared a selection of the hottest news and topics for you to catch up on!
Hello,
can someone confirm to me if image for docker deployment of IRIS are ready for production? Also what about Healtshare products?
Thank you.
Is there a way to delete a message in a routing rule? For example, an HL7 message doesn't qualify for a rule, but instead of the message being passed on to the next rule, you delete the message.
Modern platforms usually treat observability as three core signals:
OpenTelemetry (OTel) is the standard way to produce and ship all three signals.
Hey Community!
We're happy to share the next video in the "Code to Care" series on our InterSystems Developers YouTube:
I am trying to built a Task that kicks off a Workflow to pull data into HSPD, and when I try to test the Task
I keep getting TestTask+3^OSU.Workday.TerminationsTask.1 *%Exception.StatusException ERROR <Ens>ErrConfigDisabled: Configuration item 'OSU.DataSource.Workday.TermService' is disabled
But within the Namespace the OSU.DataSource.Workday.TermService shows enabled.
Here is my Task that I am using...
Class OSU.Workday.TerminationsTask Extends %SYS.Hi all,
I'm trying to learn Intersystems Iris. And I have a question.
How can I use left arrow key with if function. Also if it is possible, teach me that how can I make backspace to edit data?
P.S Sorry for bad English.
w $char(27)_"[2J"_$char(27)_"[H"
s var="12345abcde"
s curPos=$length(var)+1
w $char(27)_"[3;1H"_"First var= "_var
for {
read *key
#; Left Arrow Key
if key="?" {
}
#; Right Arrow Key
elseif key="?" {
}
#; Backspace
elseif key=8 {
}
elseif key=9 {
quit
}
}
w !,"Last var= ",var
Kind Regards,
Ikh
This time, it’s not really programming per se, but we are using React as a front-end development tool for IRIS. When using a web development framework—not limited to React—one key consideration is which CSS framework to use. Up until now, we’ve been using Bootstrap, which is the standard and the easiest to get started with.
However, while it’s easy to use, I felt that it offers limited flexibility for customization. That said, even if we were to switch to another CSS framework, learning it and rewriting everything from scratch would be a significant effort, so we left things as they were.
Is your source control treating your InterSystems IRIS environment like a simple collection of files? Most source control tools lack the native intelligence to handle InterSystems IRIS, which is why your code is treated as such.
Deltanji is different. It understands how code and other artifacts are stored within IRIS and can manage them directly. This eliminates the friction that other tools introduce to the process.
Join us for an InterSystems-hosted webinar to see how Deltanji provides an enterprise-grade source control solution that is tightly integrated with your IRIS environment.
I have two RHEL 9.7 servers. One is running intersystems in docker no problem. But, I have now tried two other servers RHEL 9.7 one, podman and one docker and I get the following.
I need to translate these labels on the Whole Record page view:
Anyone knows how to do it?
Thanks
