#InterSystems IRIS

This great article sparked some recent private discussion, and I'd like to share some of my own thoughts from it.
The motivating concern boils down to: Why do we need coding rules or conventions at all? What happened to the wonderful era of the Renaissance artist-programmer forging their own path, prior to being supplanted by the craftsman and now (even worse) by AI?
In short, there are a few reasons why coding standards/guidelines are useful, and the Renaissance artist-programmer is not entirely gone.

Reason 1: These days, when you’re training a true novice artist, you start out by having them

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.

Does anyone know how to achieve this or do you have other means to distinguish between management-port

Hi Everyone,
Please suggest/share best practices and sample questions that would help me to secure InterSystems HL7 specialist Certification.

If you want to find out what exact version your Docker image is (and since the latest image tagging scheme you cannot just rely on the image tag; and assuming you don't want to actually run it just in order to find out) you can run this docker command:

Greetings dear community members!

Many of you will remember the NLP capabilities available in IRIS under the name iKnow, which were deprecated not long ago. But...is everything deprecated? NO! A small village resists deprecation: iFind indexes!

I have a custom Buffer class which is designed to capture written/printed statements to the device, to be able to transform the captured text to string or stream type. I have used this in ObjectScript to capture ObjectScript write statements and return a string. I would like to try to use this with a [ Language = python ] method as follows. This class will be called by a scheduled task.

Overview

The typeorm-iris project provides experimental support for integrating TypeORM with InterSystems IRIS, enabling developers to interact with IRIS using TypeORM’s well-known decorators and repository abstractions. This allows a more familiar development experience for JavaScript and TypeScript developers building Node.js applications with IRIS as the backend database.

While the project implements key integration points with TypeORM and supports basic entity operations, it’s not yet battle-tested or suitable for production environments.

It appears as though command history is not available via up/down arrow keyboard keys when using the SQL Shell. Is there anything in the works to change that?

Also, typing the colon character (:) as the first character after the prompt in Terminal Lite does odd things in 2025.1.1 ... every keystroke starting with the colon is echoed back and pressing Enter generates an error:

The red :SQL on the first line was echoed simultaneously as the :SQL in white was typed. Also, it's obvious that aliases don't work in Terminal Lite 😉

IrisTest is a light weight, powerful, user-friendly tool designed to simplify unit test report generation. It includes an interactive shell and API to facilitate communication, allowing developers to easily manage and generate reports for their test runs in various formats. Whether you're debugging or creating detailed reports for analysis, IrisTest makes the process smooth and efficient!

Reviewing my published packages, I identified a nasty bug in IRIS Native API

• There is a method in  %Net.DB.Iris named function ()
• It's equivalent to  ObjectScript $$label^routine(param) 
• It used to work fine 2 years ago, when I published my command-line-extension packages
• Now it is broken since at least 1 year and throws <PROTECT>
• I identified it for ObjecScript, Java, Python, Node.js
• It is reported as WRC# 1002589
• For all 4 cases, I also verified a workaround
  • Instead of calling an ObjectScript Function you call a Classmethod
  • It's by %Net.DB.Iris ClassMethodValue(...)

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.

If you’ve ever watched a true artisan—whether a potter turning mud into a masterpiece or a luthier bringing raw wood to life as a marvelous guitar—you know that magic isn’t in the materials, but in care, craft, and process. I know this firsthand: my handmade electric guitar is a daily inspiration, but I’ll admit—creating something like that is a talent I don’t have.

Yet, in the digital world, I often see people hoping for “magic” from generative AI by typing vague, context-free prompts like “build an app.” The results are usually frustratingly shallow—no artistry, no finesse. Too many expect

This article will introduce you to the concept of virtual environments in Python, which are essential for managing dependencies and isolating project from the OS.

What is a Virtual Environment?

A virtual environment is a folder that contains :

• A specific version of Python
• At start an empty site-packages directory

Virtual environments will help you to isolate your project from the OS Python installation and from other projects.

How to use it?

To use virtual environments, you can follow these steps:

1. Create a virtual environment: You can create a virtual environment using the venv module tha

I am brand new to using AI. I downloaded some medical visit progress notes from my Patient Portal. I extracted text from PDF files. I found a YouTube video that showed how to extract metadata using an OpenAI query / prompt such as this one:

Thirteen years ago, I attained dual undergraduate degrees in electrical engineering and math, then promptly started full-time at InterSystems using neither. One of my most memorable and stomach-churning academic experiences was in Stats II. On an exam, I was solving a moderately difficult confidence interval problem. I was running out of time, so (being an engineer) I wrote out the definite integral on the exam paper, punched it into my graphing calculator, wrote an arrow with “calculator” over it, then wrote the result. My professor, affectionately known as “Dean, Dean, the Failing Machine,”

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

The Problem: Dynamic SQL and SQL Injection

Dynamic SQL constructs queries as strings at runtime. While this offers flexibility, it also creates a vulnerability if user input is not handled correctly. For exa

Overview I'm excited to announce the release of testcontainers-iris-node, a Node.js library that makes it easy to spin up temporary InterSystems IRIS containers for integration and E2E testing. This project is a natural addition to the existing family of Testcontainers adapters for IRIS, including testcontainers-iris-python and testcontainers-iris-java.

Why testcontainers-iris-node? As a Node.js developer working with InterSystems IRIS, I often faced challenges when setting up test environments that mimic production. testcontainers-iris-node solves this by leveraging the testcontainers-node framework to create isolated IRIS environments on-demand.

This is particularly valuable for:

• Integration testing with IRIS databases
• Testing data pipelines or microservices
• Automating test environments in CI pipelines

Features

• Launches IRIS in Docker containers using Testcontainers
• Supports custom Docker images and configuration
• Wait strategies to ensure IRIS is ready before tests begin
• Clean teardown between test runs

Why Randomization is Key When Splitting Data for Machine Learning

Post:
Essentially, Machine Learning is about learning from data. Having "good" data leads to better models, and more importantly, the quality of the information being used plays a crucial role in improving prediction accuracy.

One critical step in the process is how we separate our data into training and validation sets. If this isn’t done properly, we risk introducing bias, overfitting, or unrealistic performance expectations for the model.

In this article, we’ll explore:

• Best practices for randomization when splitting d

Well... It's time for testing. We know that often, it's already over. So, what now? Can I improve the quality of my development?

The answer is: YES. Yes, you can. The Toolqa tool aims to do just that. It's a facilitator. What's its goal?

To ensure that APIs meet pre-established business requirements, while also protecting against <sarcasm>  future failed attempts </sarcasm>  to destroy your application, website, app, or anything else that uses your API.

Now you might be wondering, how does this happen? Where's the magic?

Hi everybody,

A customer would like to connect an IRIS database to Metabase BI.  But Metabase does not have a connector that supports the IRIS database.

Metabase only supports these databases:

- Amazon Athena
- BigQuery (Google Cloud Platform)
- Druid
- MongoDB (recommend version 4.2 or higher)
- MySQL (recommend version 8.0.33 or higher, as well as MariaDB version 10.4 or higher)
- Oracle
- PostgreSQL
- Presto
- Redshift (Amazon Web Services)
- Snowflake
- SparkSQL
- SQL Server
- SQLite
- Vertica

And a few others. 

However, it is possible to create a driver for Metabase that connect to IRIS.  Metabas

Hello everyone,

I would like to ask whether it is possible to run InterSystems API manager (IAM) on OpenShift. Is there some documentation describing how to do it? I was searching the forum as well as the internet and I have not found much unfortunately.

Any hints would be highly appreciated.
