I've modified the class file, but messages still arrive as a single line (e.g., "H|.../rQ|.../rL") instead of separate lines in the ASTM service. The <ENQ>..<EOT> header looks correct, logs show no errors, and the service receives messages fine. Is there an Ensemble 2018.1 engine setting (like line terminator handling or TCP framing) to fix the line splitting? ​

When using InterSystems IRIS as an interoperability engine, we all know and love how easy it is to use the Message Viewer to review message traces and see exactly what's going on in your production. When a system is handling millions of messages per day, you may not know exactly where to begin your investigation though.

Over my years supporting IRIS productions, I often find myself investigating things like...

Hi everyone,

Does anyone know how to export projects via VSC?

I opened the project through the "InterSystems Tools" plugin (command is "Edit Code in Project") and I can correctly work on it.

However, when I try using the "ObjectScript" plugin to export the project (right click on the project -> "Export Project Contents")

This message appears and it is not possible to export the project:

An Overview of Database Degrade

Introduction

Hello! In this article, I will be discussing database degrade, a type of data integrity issue one can face when using IRIS. First, I will be going over a review of the structure of IRIS databases. I'll then discuss how database degrade can manifest and common causes of degrade issues. I'll then conclude with general tips we give our customers about how to prevent or prepare for database degrade issues.

Hello everybody,

I would like to export project contents using Visual Studio Code, as well as I do with InterSystems Studio.

However, while attempting the export through the InterSystems extension I get the following error:

- There are no folders in the current workspace that code can be exported to.

These are the step to reproduce my error:

Hi Community! 👋

As 2026 gets underway, we’d love to hear what you’re focusing on this year.

This discussion is a space to share your resolutions, goals, and focus areas for 2026 - technical, professional or community-related.

These don’t have to be traditional New Year’s resolutions. Think of them as intentions or priorities you’d like to work on this year.

Hi Community,

We’re excited to invite you to take part in shaping the next generation of ObjectScript development tools. We’re working on an AI-powered ObjectScript coding assistant designed specifically for IRIS developers. Not a generic AI adapted for ObjectScript, but a solution built from the ground up to understand ObjectScript idioms, IRIS APIs, interoperability productions, and real-world developer workflows.

To make sure we build something truly useful, we need your input.

Hi Gang!

Did you know you can deploy InterSystems IRIS Community Edition on the cloud without paying for a license? You can try for free, and it could even come in handy if you want to show off that shiny new app you've created (maybe for the full stack competition..?)

In this article I will provide a complete walkthrough on how to deploy IRIS on Amazon Web Services (AWS), and will also add a follow up for deploying on Azure.

Now before I begin the walkthrough, I want to admit that I was terrified of using AWS the first time because I'd seen memes about how easy it is to rack up costs on AWS. So if you're thinking the same, I suggest you start by signing up to a Free Tier Account, which gives you $100 free credit to evaluate, and automatically shuts off to prevent charges. InterSystems IRIS Community Edition has a free license so if you pair the two, you can deploy without risk and completely for free. (Disclaimer: although I'm sure this is true, please do read the free account terms and make your own decisions 😅 )

Here at InterSystems, we often deal with massive datasets of structured data. It’s not uncommon to see customers with tables spanning >100 fields and >1 billion rows, each table totaling hundred of GB of data. Now imagine joining two or three of these tables together, with a schema that wasn’t optimized for this specific use case. Just for fun, let’s say you have 10 years worth of EMR data from 20 different hospitals across your state, and you’ve been tasked with finding….

A .iostream file got stored in /intersystems/HCENG01B12/mgr/Temp for a BatchFileOperation class while HC was on the secondary node. HealthConnect is now on the primay node and cannot find that .iostream file path. The operation starts throwing errors when the RolloverSchedule is reached

OnKeepalive() returned ERROR #5012: File '/intersystems/HCENG01B12/mgr/Temp/QWhoZAwFF3f9jQ.iostream'
does not exist

How can I resolve this issue?

New AI CCR Assistant

CCR now includes an AI-powered 'CCR Assistant', available to beta testers. The CCR Assistant helps you quickly get answers about common CCR workflows, terminology, or best practices. Every response includes references to relevant ICC Training courses, making it easy to dive deeper into any topic. As a future improvement, the links will point directly to the specific page of the ICC Training PDF that was used to generate the response.

Currently in the health connect code, we are using Epic FHIR API Patient.Create, code return 200 or 201 status values, we process the message based on this return values.

How many times have you had to receive or generate a JSON and wished you could work on it using DTLs without having to deal with DynamicObjects trying to remember the name of each field? Do you want to break down and make your giant JSON file more digestible?

In my case, never, but I thought that someone might find it useful to have a feature that captures your JSON and breaks it down into a series of ObjectScript classes that you can work with more easily and conveniently.

Well then...behold JSON2Class in all its glory!

Hello Community,

I am facing a JDBC connection issue after migrating from Caché 2016 to Caché 2018.1. When I attempt to connect using the following connection settings:

CACHE_DATASOURCE_URL=jdbc:Cache://localhost:1972/TEST

CACHE_DB_USERNAME=test

CACHE_DB_PASSWORD=test

I consistently receive the following error:

[Cache JDBC] Communication link failure: Access Denied

This configuration worked perfectly with Caché 2016. I have verified the following:
