Hi everyone,

I’m thrilled to share that after several years of deep diving into the InterSystems IRIS data platform, I have finally summarized my project experiences into a new book IRIS (Data Platform) Programming Technical Guide. It is published by Beihang University Press, a prestigious central-level comprehensive publisher renowned for its leading role in aerospace, science, and technology publishing.

Writing this book was a significant engineering challenge for me. My goal was to bridge the gap between "understanding the syntax" and "building a production-ready project.

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.

Intro

If you ever wondered how to debug some requests that are being made to or from IRIS, well here is a little tutorial on how to do that.

During a complex project, usually you get the specifications and implement the communication between IRIS and other things based on that. But from the paper to the real world there's usually a huge gap and you need to know why you are receiving an error on a parameter, on a header, you are not receiving the data and so on.

Data privacy regulations such as GDPR, LGPD, and HIPAA demand that organizations know exactly where Personally Identifiable Information (PII) lives inside their databases. Yet in practice, most teams rely on manual inventories, tribal knowledge, or external scanning tools that require data to leave the database engine — a process that itself creates privacy and security risks.

This article presents an MVP that takes a different approach: it runs PII detection inside InterSystems IRIS using Embedded Python, analyzing data where it lives and never exporting it to an external process.

In case you're planning on deploying IRIS For Health, or any of our containerized products, via the IKO on OpenShift, I wanted to share some of the hurdles we had to overcome.

As with any IKO based installation, we first need to deploy the IKO itself. However we were getting this error:

Warning FailedCreate 75s (x16 over 3m59s) replicaset-controller Error creating: pods "intersystems-iris-operator-amd-f6757dcc-" is forbidden: unable to validate against any security context constraint:

proceeded by a list of all the security context constraints (SCCs) it could not validate against.

Introduction

In healthcare interoperability environments, InterSystems Health Connect typically contains critical components such as productions, business processes, operations, services, utility classes, routines, and other ObjectScript artifacts. Traditionally, many deployments of these components have been done manually, by copying classes, importing XML, or using administrative tools from the management portal.

For those of you that weren't at READY last week, you may have missed the exciting announcement that the Early Access Program for AI Hub is officially open. It was announced during an amazing demo from @Benjamin De Boe and @Jeff Fried, I recommend catching up with this demo when the recording is released!  I had the opportunity to play with AI Hub in advance, and thought I might share an introduction with the community.

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.).

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.

A very important feature for HL7 FHIR has been introduced with the release of v2026.1 - the support for SMART on FHIR v2 fine-grained granular Scopes.

This enables you to be much stricter and more accurate in the access you provide to the data in your FHIR repository.

Part of this new support is to refuse requests that don't match the scopes, but an even more interesting ability is to filter the results according to the provided scopes.

I am regularly contacted by customers about memory sizing when they get alerts that free memory is below a threshold, or they observe that free memory has dropped suddenly. Is there a problem? Will their application stop working because it has run out of memory for running system and application processes? Nearly always, the answer is no, there is nothing to worry about. But that simple answer is usually not enough. What's going on?

Consider the chart below. It is showing the output of the free metric in vmstat

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

InterSystems FAQ rubric

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.

Temporary Globals and the IRISTEMP Database

By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

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:

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

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).

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.

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.

A Continuous Training (CT) pipeline formalises a Machine Learning (ML) model developed through data science experimentation, using the data available at a given point in time. It prepares the model for deployment while enabling autonomous updates as new data becomes available, along with robust performance monitoring, logging, and model registry capabilities for auditing purposes.

InterSystems IRIS already provides nearly all the components required to support such a pipeline. However, one key element is missing: a standardised tool for model registry.

Hi All,

First I want give a Shout Out to @Theo Stolker  and @Rupert.Young. Because they helped me with the solution.

 When you're using the EnsLib.SQL.Snapshot as a Property in the Response Message to return Snapshot data (,e.g.: from Business Operation to Business Process,) the Snapshot data won't be cleaned with the Purge messages task/service.

Class ResponseMessage Extends Ens.Response

{

    Property SnapshotProp As EnsLib.SQL.Snapshot;

}

The data will be stuck in the global: ^Ens.AppData. You can find it with this query in System>Globals:  ^Ens.AppData("EnsLib.SQL.

Working in healthcare IT as a young developer, especially on InterSystems TrakCare, you quickly realize one thing: it’s not just about HL7 messages or backend integrations. A hugepart of making TrakCare work smoothly for hospitals comes down to how it’s configured, customized, and supported on the application side.

That’s where people like me come in—techno-functional developers who understand both the tech and how it impacts actual hospital workflows.

We’re Not Just Techies (or Functional Consultants)

Our role sits right in the middle.
