I'm using this service to create a FHIR facade.

I want to return OperationOutcome to the calling application when I detect an error.

My code at present is :

What is a FHIR Profile?

A FHIR profile is a collection of rules and constraints used to customize and refine a base Fast Healthcare Interoperability Resources (FHIR) resource. Profiling is a vital process that adapts the base FHIR resource standard to satisfy the unique requirements of a specific use case, geographic region, medical institution, or clinical workflow.

While the base FHIR specification provides generic, flexible definitions for resources (such as Patient, Observation, or Medication), profiles transform these generic resources into more precise ones. This ensures consistent and interoperable data exchange tailored for a particular community or implementation.

FHIR is designed to cover various healthcare scenarios globally. Profiles allow implementers to adapt this general platform without losing the benefits of standardization.

Given a sting beginning with "-----BEGIN CERTIFICATE-----" and ending with "-----END CERTIFICATE-----", how do I save the string as X509 certificate in ObjectScript?

Hi

I see AlertGroups dropdown shows emails under operations and processes.

Need help where I can find email accounts which shows under AlertGroups dropdown?

We’re excited to announce the first mini hackathon “Building AI Agents with InterSystems”, taking place on a pre-conference day as part of InterSystems READY 2026.

In this hands-on challenge, participants will design and build AI agents using upcoming InterSystems capabilities, exploring how intelligent automation, orchestration, and reasoning can be applied to practical use cases.

📅 Event date: 27 April 2026
📍 Location: Gaylord National Resort & Convention Center, National Harbor, Maryland

Needs some help with FHIR return code 200 or 201 when processing HL7 messages in HealthConnect.

Issue:

1. If FHIR code is 200 or 201, HealthConnect keep processing HL7 messages

2. If FHIR code is NOT 200 or 201, HealthConnect keep suspend the HL7 messages in the messages queue, then keep processing NEXT subsequent HL7 messages in the TEXT file if the FHIR code is 200 or 201

Over the last 9 years, I published more than 90 packages in OEX.
And over this time, conditions and environments changed.
In the beginning, there was

• no Docker
• no IPM/ZPM
• no embedded Python, no AI
• Caché, Ensemble, CSP, ZEN, .... were dominating

As time changed, also product versions and external languages changed.
Adjustment of a few packages was no issue in the beginning,
and was a matter of support quality to my "consumers".

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.

RabbitMQ is a message broker that allows producers (those who send a data message) and consumers (those who receive a data message) to establish asynchronous, real-time, and high-performance massive data flows. RabbitMQ supports AMQP (Advanced Message Queuing Protocol), an open standard application layer protocol.
The main reasons to employ RabbitMQ include the following:

• You can improve the performance of the applications using an asynchronous approach.
• It lets you decouple and reduce dependencies between services, microservices, and applications with the help of a data message mediator, meaning that there is no need for producers and consumers of exchanged data to know each other.
• It allows the long-running processing of sent data (with the results) to be delivered after utilizing a response queue.
• It helps you migrate from monolithic to microservices, where microservices exchange data via Rabbit in a decoupled and asynchronous way.
• It offers reliability and resilience by making it possible for messages to be stored and forwarded. A message can be delivered multiple times until it is processed.
• Message queueing is the key to scaling your application. As the workload increases, you will only have to add more workers to handle the queues faster.
• It works well with data streaming applications.
• It is beneficial for IoT applications.
• It is a must for Bots’ communication.

There are numerous excellent tools available for testing your REST APIs, especially when they are live. Postman, various web browser extensions, and even custom ObjectScript written with %Net.HttpRequest objects can get the job done. However, it is often difficult to test just the REST API without inadvertently involving the authentication scheme, the web application configuration, or even network connectivity. Those are a lot of hoops to jump through just to test the code within your dispatch class. The good news is that if we take our time to understand the inner workings of the %CSP.REST class, we will find an alternative option suited for testing only the contents of the dispatch class. We can set up the request and response objects to invoke the methods directly.

Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance. Do you know all the parameters that affect the memory allocated by IRIS ?
