One of the newest features of .Net core 10 with C# 14 is the file-based apps. This feature allows you to execute C# code in a simple .cs file without the need to create a solution, a project, or any of the related structure.
For example you can create a script.cs file using the notepad with the content:
Console.WriteLine(“This is a script in c#.”);
Then in the command line or the terminal you execute the command:
FastJsonSchema: High-Performance JSON Validation in IRIS
Validating JSON data against JSON Schema is a common requirement for modern applications. FastJsonSchema brings this capability natively to InterSystems IRIS, combining speed, simplicity, and full schema compliance.
Unlike traditional validation approaches, FastJsonSchema generates native ObjectScript code from your JSON Schemas and compiles it directly to iris object code, enabling idiomatic performance without relying on external libraries or runtimes.
Hello Developers! 👋 I’m excited to introduce IRIS IO Utility, my submission for the InterSystems "Bringing Ideas to Reality" Contest 2025. This VS Code extension provides you an intuitive and powerful interface for importing and exporting data without leaving your IDE.
I am using Object Script with Phyton to import an Excel File.
Please see the below code. Its works fine for all text and numeric Columns. But by importing a DATE formated column in Excel (birthdate) , Iam facing the below issue as result:
As part of an ongoing mission to track down orphaned HL7 Messages in our integration engine, I have been digging into our environment to track down the causes.
Having looked at various posts here (including one of my own) there are a few scenarios that can create orphaned messages resulting in excessive disk space usage. These scenarios are generally:
In some cases, it's necessary to manipulate data from one namespace to another. For example, a routine in the "N1" namespace needs data from the "N2" namespace. In legacy systems (using only globals), it's common to make the global universal, but what about persistent classes? Is this type of globalization also possible?

We are a group of interface analysts in a healthcare setting, running IRIS for Health 2024, having upgraded over time from an old ENSEMBLE environment. We have been working on a wish list of development goals, but are having trouble finding the correct, best practice method/path for getting to what we envision.
I’m facing an issue with a CSP-based web application. The default.csp page loads correctly on both servers. However, when I try to open or submit the login.csp page on one server, it shows the error:
InterSystems IRIS provides extensive configurable security options, yet many developers primarily use roles and resources to secure entire tables or routines. Today, we will delve deeper. We can also secure individual columns and rows separately, but these two mechanisms operate very differently. Let's begin with the columns.
Column Security
For testing and demonstration, we will keep our table structure concise and straightforward. We have a table called "Person" in the USER namespace that contains an ID column, a date of birth column (DOB), first name, and last name.
I am using IRIS for Windows (x86-64) 2022.1 (Build 209) Tue May 31 2022 12:27:55 EDT [Health:3.5.0]. I created Interoperability Production with a Service to read file from S3 bucket and an Operation to write files to a different S3 bucket. I specified AWS ProviderCredentialsFile.
I see "Terminating Job 7096 / 'From S3 Bucket' with Status = ERROR #5023: Remote Gateway Error: Connection cannot be established, %QuitTask=
Do I need anything like Python libraries or AWS CLI to make this work?
Recently, we implemented some Java-based services using JDBC. And some time ago, I refactored some legacy PHP programs that used "csession" for communication between systems to use PDO with ODBC.
This raised a question for me about how license management is done in this scenario. Is a license used per pool? Or per connection? How is this management done?
Want to build smoother communication between payer systems and providers? See how the Prior Authorization Support (PAS) module of the InterSystems Payer Services ePrior Authorization solution can help:
There's a pattern I've encountered several times where I need to use a temp file/folder and have it cleaned up at some point later.
The natural thing to do here is to follow the patterns from "Robust Error Handling and Cleanup in ObjectScript" with a try/catch/pseudo-finally or a registered object to manage cleanup in the destructor. %Stream.File* also has a "RemoveOnClose" property that you can set - but use with care, as you could accidentally remove an important file, and this flag gets reset by calls to %Save() so you'll need to set it back to 1 after doing that.
There's one tricky case, though - suppose you need the temp file to survive in an enclosing stack level. e.g.:
We're working on new capabilities to help you build Agents and AI applications faster with InterSystems IRIS. In order to better understand which entry points and development methodologies would help you most, we've created this brief survey: Building AI solutions with InterSystems IRIS.
Filling it in should not take much more than 5 minutes, and your feedback on this exciting topic will help us fine tune our designs and prioritize the right features.
Security is fundamental to enterprise application development. InterSystems IRIS provides a comprehensive security framework that protects data, controls access, and ensures compliance. This guide introduces essential security features for developers new to IRIS, covering authentication, authorization, encryption, and practical implementation strategies.
