Hola amigo! 😊 Cómo estás hoy,

I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors. 

How does a Payment Machine actually work?

It's simple, start by initiating/creating a transaction, then retrieve its payment status.

Here, initiate/create refers to POST method and Retrieve refers to GET.

IRIS 2023.3.0 ASQ

Abstract Set Query, ASQ, is a super set of JSON Path Language, JPL, which was first introduced by the 2016 ISO SQL Standard. JPL is only defined within the context of SQL. In 2023.3, we introduced classes that implement ASQ. It works on any implementation of %Library.AbstractSet. The complete syntax for ASQ will be documented later. This is just a quick introduction to a few of its features. This implementation comes with a nice utility as well. You will know it when you see it!

First, let's get some data from the NHL database.This step requires a valid SSL/TLS configuration.

Hi,

We currently have a zen page we created to show all existing tasks and their states (Running or Stopped) as below, is the a way to do the same and create a page where we can list all Business Services of a production, state and to either Stop or restart them?  

Thanks

For developers building external applications, especially those using familiar technologies like C#, ODBC (Open Database Connectivity) is a crucial, standardized bridge to any relational database, including InterSystems IRIS. While InterSystems offers its own native ADO.NET provider, the ODBC driver is often the most straightforward path for integration with generic database tools and frameworks.

Here is a step-by-step guide to getting your C# application connected to an IRIS instance using the ODBC driver, focusing on DSN-less connection string.

Step 1: Install the InterSystems IRIS ODBC Driver

The InterSystems ODBC driver is installed by default when you install InterSystems IRIS on a Windows machine.

• If IRIS is on the same machine: The driver is already present.
• If IRIS is on a remote server: You must download and install the standalone ODBC client driver package for your client operating system (Windows, Linux, or macOS) and bitness (32-bit or 64-bit) from WRC website if you're a client or by installing Client components and copying ODBC driver.

Once installed, you can verify its presence in the ODBC Data Source Administrator tool on Windows (look for the InterSystems IRIS ODBC35 driver).

Hi everyone,
I'm getting prepared to take the following certification exam: "InterSystems IRIS Development Professional".

Can you give some advice on how to prepare (aside from the official course page: https://www.intersystems.com/certifications/intersystems-iris-development-professional/ )?
Do you have examples of quiz questions that simulate the real exam or any material that helped you getting prepared?

Thanks you in advance,

Arber

Hello 

I'm using from visual code. My routines are server-side files. If I try to search patterns in files (e.g find all routines containing the string "version=3") , the search runs but didn't find anything. If I do the same search from the management portal, it finds all routines including this pattern with a good performance.

Modern data architectures utilize real-time data capture, transformation, movement, and loading solutions to build data lakes, analytical warehouses, and big data repositories. It enables the analysis of data from various sources without impacting the operations that use them. To achieve this, establishing a continuous, scalable, elastic, and robust data flow is essential. The most prevalent method for that is through the CDC (Change Data Capture)  technique. CDC monitors for small data set production, automatically captures this data, and delivers it to one or more recipients, including analytical data repositories. The major benefit is the elimination of the D+1 delay in analysis, as data is detected at the source as soon as it is produced, and later is replicated to the destination.

This article will demonstrate the two most common data sources for CDC scenarios, both as a source and a destination. For the data source (origin), we will explore the CDC in SQL databases and CSV files. For the data destination, we will use a columnar database (a typical high-performance analytical database scenario) and a Kafka topic (a standard approach for streaming data to the cloud and/or to multiple real-time data consumers).

Overview

This article will provide a sample for the following interoperability scenario:

Hi developers!

How do you debug implementation code in .impl classes of REST.API in InterSystems IRIS?

Especially if you don't have access to globals, so no things like: 

Set^AAA="here we are"

not possible in this case.

Suppose I have the following signature of the REST.API method called as POST and containing JSON. :

In my previous article, I structured network communications
in these 3 possible layers, and covered the last

• Client <---> Transport
• Server <---> Transport
• Client <---> Server

In fact, you have the most control over the last one.
The IRIS side as a server is yours and under your full control. 
Up to now, the Transport layer was assumed to be as passive as a bare wire.

This assumption should be verified. I once met a Windows environment with
a quite surprising setup where a Firewall-like filter was isolating internal
processes and causing a lot of trouble.

? What can you do about the  Transport

Chasing errors or misbehavior in the network can be quite a challenge.
Differently to  a local application on the DB server, you always have at least 3 players:

• A client  to place a request 
• some kind of transport layer
• and a server to provide a reply.

This results in a minimum of 3 possible communication layers

• Client <---> Transport
• Server <---> Transport
• Client <---> Server

The last one is probably the easiest  to check, while the other 
two deal with the same counterpart just from opposite sides.

?  Do both ends use the same communication protocol ?

I met more than once that one end

Over the past several years, the InterSystems Developer Community has accumulated more than 1,000 open-source projects. Many of them serve as examples and learning materials — but a significant number have become useful tools, libraries, integrations, and real-world components used in production.

Some of these projects are mine, and like many community developers, I’ve seen the same recurring problem:

• It’s easy to create an open-source project.
• It’s hard to maintain, support, and develop it sustainably — especially without funding.

Writing code is one thing.
Supporting it for years, keeping up with new IRIS versions, building CI pipelines, writing documentation, fixing issues, reviewing PRs — all of this demands both time and motivation, and the biggest motivator is often financial support.

This is not a new challenge.
The global open-source world has faced this for decades and has developed various models to support OSS ecosystems.

I believe it’s time for the InterSystems community to start a discussion about adopting a similar model.

I would like to share with you a little trick to customize how messages are displayed in the Message Viewer. In particular, how you can display messages as JSON (instead of the default XML representation).

Messages are objects that are used to communicate interoperability productions components. In my example I have defined a message that later I serialize as JSON to send to an external API. This message is defined as a regular message and also as a %JSON.Adaptor so I can export / import directly to or from JSON.

Class interop.msg.DeviceOrderReq Extends (Ens.Request, %JSON.Adaptor)

⏯ Using SerenityGPT to Build Out an Application GenAI Middleware at InterSystems @ Ready 2025

Introduction

In this article, we will explore various approaches to extending and customizing the behavior of InterSystems IRIS (and IRIS Health) built-in interoperability message routers.

Message routers perform one of the core functions of Enterprise Application Integration (EAI) and are among the most frequently used business processes in interoperability productions.

After a brief overview of the built-in message router classes in InterSystems IRIS and IRIS for Health, the article will demonstrate how to enhance their capabilities to achieve specific outcomes—without the need to develop a

When IRIS 2023.2 reaches general availability, we’ll be making some improvements to how we tag and distribute IRIS & IRIS for Health containers.

IRIS containers have been tagged using the full build number format, for example 2023.1.0.235.1.  Customers have been asking for more stable tags, so they don’t need to change their dockerfiles/Kubernetes files every time a new release is made.  With that in mind, we’re making the following changes to how we tag container images.

Major.Minor Tags:  Containers will be tagged with the year and release, but not the rest of the full build number.   For

⏯ Operations & Scalability with InterSystems IRIS - From Zero to Hero @ Ready 2025

Hello!

I'm trying to create some foreign tables to a PostgreSQL database. In some cases, columns with certain datatypes cannot be consumed by IRIS and the following error is thrown:

 [SQLCODE: <-237>:<Schema import for foreign table did not return column metadata>]

  [%msg: <Unkown data type returned by external database>]

For example: serial4 typed ID columns are typical examples. Is it possible, what's the best way of resolving these datatypes, which- seemingly- don't have proper JDBC metadata mappings?

Of course, explicitely defining columns and types as part of the CREATE FOREIGN TABLE

As a developer who uses Cache as DB for a couple of projects, I'm using REST API's every time, knowing how to consume a resource from REST API, in my opinion, it's crucial to know how to consume external REST Api's using %Net.HttpRequest because it enables integration with modern web applications and services, and it's a crucial skill for a backend developer who loves and uses Cache as a DB.

What and who is %Net.HttpRequest

its just a class but this is the proper way of making request outside of the framework, this is just a simple class who provide HTTP methods like GET, POST and PUT and all

Introduction

The InterSystems IRIS Data Platform has long been known for its performance, interoperability, and flexibility across programming languages. For years, developers could use IRIS with Python, Java, JavaScript, and .NET — but Go (or Golang) developers were left waiting.

That wait is finally over.

The new go-irisnative driver brings GoLang support to InterSystems IRIS, implementing the standard database/sql API. This means Go developers can now use familiar database tooling, connection pooling, and query interfaces to build applications powered by IRIS.

Why GoLang Support Matters

GoLang is a language designed for simplicity, concurrency, and performance — ideal for cloud-native and microservices-based architectures. It powers some of the world’s most scalable systems, including Kubernetes, Docker, and Terraform.

Bringing IRIS into the Go ecosystem enables:

• Lightweight, high-performance services using IRIS as the backend.
• Native concurrency for parallel query execution or background processing.
• Seamless integration with containerized and distributed systems.
• Idiomatic database access through Go’s database/sql interface.

This integration makes IRIS a perfect fit for modern, cloud-ready Go applications.
