In my previous HttpRequests, I have used Content-Type = application/json but I have a vendor that is requesting we send application/x-www-form-urlencoded. How would I go about formatting the Payload as x-www-form-urlencoded?

Thanks

As applications grow, every database eventually hits scaling limits. Whether it's storage capacity, concurrent users, query throughput, or I/O bandwidth, single-server architectures have inherent constraints. This guide explains fundamental approaches to database scalability and shows how InterSystems IRIS implements these patterns to support enterprise-scale workloads.

We'll explore two complementary scaling strategies: horizontal scaling for user volume (distributing computational load) and sharding for data volume (partitioning datasets). Understanding the general principles behind these approaches will help you make informed decisions about when and how to scale your IRIS applications.

The examples in this guide use InterSystems IRIS in Docker containers.

IPM version 0.10.5 has been released on January 15, 2026. This new version contains a ton of improvements and bug fixes so be sure to check it out either directly from the GitHub page or from the Community Registry!

The big changes include the following:

• A rewrite of dependency resolution that drastically improves performance, including a 200x speed increase in very complicated cases
• A History Log that tracks the IPM installs, loads, updates, and uninstalls that can be viewed using zpm "log" 
• System expressions, like ${namespace}, and $$$ macros are now evaluated in CPF merge files allowing

How I Vibecoded a Backend (and Frontend) on InterSystems IRIS

I wanted to try vibecoding a real backend + frontend setup on InterSystems IRIS, ideally using something realistic rather than a toy example. The goal was simple: take an existing, well-known persistent package in IRIS and quickly build a usable UI and API around it — letting AI handle as much of the boilerplate as possible. Here is the result of the experiments.

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? ​

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.

IRIS Database Structure

What exactly is a database?An IRIS database is a single file that consists of a fundamental unit called the "block".

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:

1. Create and save a new VSCode workspace
2. Open a local directory 
3. Go to the InterSystems extension
4. Open "Projects" panel and right-click on the project you want to export
5. Click on "Export Project Contents"

Anyone can help me solving this issue?

Thank you

This article explains how to deploy InterSystems IRIS Community Edition on AWS using the AWS Marketplace and EC2. It covers prerequisites, instance selection, security settings, SSH access, and first verification steps. The deployment can be completed using the AWS Free Tier and is suitable for developers who want to quickly start working with IRIS in the cloud.

Who this guide is for.

This guide is intended for developers, solution architects, and DevOps engineers who want to deploy InterSystems IRIS Community Edition on Amazon Web Services (AWS). No prior AWS automation experience is required, but basic familiarity with EC2 and SSH is helpful.

What you will achieve.

After completing this guide, you will be able to:

1. Launch InterSystems IRIS Community Edition on AWS
2. Configure a secure EC2 instance
3. Connect to IRIS using SSH and the Management Portal
4. Verify that IRIS is running correctly

Prerequisites

Before you begin, make sure you have:

1. An active AWS account
2. Permissions to create EC2 instances and security groups
3. An SSH key pair configured in AWS
4. Basic knowledge of Linux command line

Deployment overview

The deployment process consists of the following steps:

1. Launch IRIS Community Edition from AWS Marketplace
2. Select an EC2 instance type
3. Configure networking and security
4. Connect to the instance via SSH
5. Verify IRIS installation

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 😅 )

Note, this article walks through deploying IRIS Community  on AWS, however the same guide can be followed to deploy IRIS for Health Community Edition, or with Bring-your-own-licence editions of IRIS and IRIS for Health, to deploy a fully licensed, production version of IRIS on AWS.

How can I programmatically retrieve a SQL query execution plan and analyze its results?

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….
   every clinician within your network
      who has administered a specific drug
         between the years of 2017-2019
    

Can the IRIS SQL engine be extended with custom optimization rules (e.g., prioritizing certain indices or join orders)? If not, is there a supported way to influence cost models?

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,

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

1. The namespace (TEST) exists and is correctly specified in the connection URL.
2. The credentials (username: test, password: test) are correct.

Some concepts make perfect sense on paper, whereas others require you to get your hands dirty. Take driving, for example. You can memorize every component of the engine mechanics, but that does not mean you can actually drive.

You cannot truly grasp it until you are in the driver's seat, physically feeling the friction point of the clutch and the vibration of the road beneath. While some computing concepts are intuitive, Intelligent Agents are different. To understand them, you have to get in the driver's seat.

In my previous articles regarding AI agents, we discussed such tools as CrewAI and La
