Hi Developers!
Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices?
if 10K lines OK? How do you cope with it? Please share?

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.
Hey Developers,

Hey Community,
We're bringing our Developer Ecosystem session back to READY 2026.
👥 Streamlining Development Workflow with InterSystems Developer Community and Ecosystem
🗓️ Wednesday, April 29, 2026
🕑 3:30 PM – 3:50 PM ET

A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.
A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.
If you already know Java (or .Net) and perhaps also have used other document databases (or looking for one), but you are new to the InterSystems world, this post should help you.
InterSystems IRIS Cloud Document is a fully managed document database that lets you store JSON documents and query them with familiar SQL syntax, delivered as a cloud service managed by InterSystems.
In this article pair I’ll walk you through:
- Part I - Intro and Quick Tour (this article)
- What is it?
- Spinning up an InterSystems IRIS Cloud Document deployment
- Taking a quick tour of the service via the service UI
- Part II - Sample (Dockerized) Java App (the next article)
- Grabbing the connection details and TLS certificate
- Reviewing a simple Java sample that creates a collection, inserts documents, and queries them
- Setting up and running the Java (Dockerized) end‑to‑end sample
The goal is to give you a smooth “first run” experience.
Starting with InterSystems IRIS 2025.1, the way dependent cubes are handled in cube builds and cube synchronizes was changed.
This change may require modifying custom build/synchronize methods. If you are using the Cube Manager, these changes are already considered and handled, which means no action is needed.
Prior to this change, cubes were required to be built and synchronized in the proper order and account for any cube relationships/dependencies. With this change, dependent cubes are automatically updated as needed when using the %BuildCube or %SynchronizeCube APIs.
Please, provide Code example to build a %Library.DynamicObject or a %Library.DynamicArray from Resultset followed by converting to JSON

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:
- Projects bundle different file types (CLS, MAC, INT, CSP). Importing the project as a whole is much more efficient than picking individual files piece by piece.

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 developers!
In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:
Classmethod Planets() as %DynamicObject {
set val1="Jupiter"
set val2="Mars"
// this doesn't work! cannot compile
return {"value1":val1, "value2":val2}
}So I need to do the following:
Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

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.

Hello and welcome to the Developer Ecosystem News!
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!
Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.
InterSystems Studio
Exporting Server Connections
Migrating Studio connections was the most challenging part.

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:
- Metrics
- Logs
- Traces
OpenTelemetry (OTel) is the standard way to produce and ship all three signals.

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
ClassMethod TestTask()
{set tTask = ##class(OSU.Workday.TerminationsTask).%New()set tTask.DaysBack = 1 $$$ThrowOnError(tTask.OnTask())}
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...

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,

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.
The InterSystems Ready 2026 Conference is approaching fast — it's a great time to prepare and check your knowledge before attempting one of the Certification exams onsite .
InterSystems certifications aren't easy: you need to practice with questions aligned to the real exam objectives.
exam-prep.es is a free platform built for exactly that: practice, identify weak spots, and show up better prepared.
