#InterSystems IRIS for Health

Hi Community,

Here we have requirement to process messages min 10 sec delay. Current time it is taking my businessProcess is less than 1 sec.

To implement this requirement , I need to sleep 10 sec in business process custom code.

Could somebody help me to implement delay in BusinessProcess.

Thanks,

Hi developers!

In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite
select top 10 ID from some_table where row_status in ('I','U') order by ID - the same
select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I asked Gemini and it recommended me rewrite the query as

Hi,
I need to create a bundle of synthetic data in order to populate FHIR servers (not mine).

Can I use a predefined ids, or is it possible the one of the servers will not allow using my IDs and replace them with it's automatic numbering?

Hello, I am trying to get some fields from HL7 message and create a file using BPL. The values I need are in a repeating segment (AIG). Even in the repeating segment, I just want the iteration that has a certain field (AIG:3 populated). With the help of documentation and community posts, I was able to create the BPL to loop through all of AIG and create the file. But when I try to narrow the results even further (AIG:3 present), the process gets stuck. I am not sure I am missing anything or have anything incorrectly set up. Also, since the process gets stuck, it doesn't even seem to h

Hi,

I want to consume an API that provides HL7 messages. To achieve this, I have thought of the following workflow:

I have created a business service that periodically triggers a business process. The trigger request is forwarded to a business operation. There, a %Net.HttpRequest is assembled from scratch and then sent to the API endpoint. The corresponding HttpResponse then contains several HL7 messages encoded in UTF-8 in the message body. To further process the HL7 messages, the operation sends the HttpResponse back to the business process as EnsLib.HTTP.GenericMessage.

I have always struggled with Iterating through a JSON response to pull out certain fields into a Data Class Structure to use to populate fields in a DTL. So I defined the whole structure for the following JSON, with the base structure extending Ens.Response, %XML.Adaptor, and %JSON.Adaptor.

TL;DR This article explains how to deploy InterSystems IRIS Community Edition on Azure using the Azure Marketplace and a Virtual Machine. It covers prerequisites, instance selection, authentication, SSH access, first verification steps, and how to delete resources to avoid charges. The deployment can typically be done using Azure free credits 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 Microsoft Azure. No prior Azure automation experience is required, but basic familiarity with the Azure Portal and SSH is helpful.

After following this guide, you will be able to:

• Launch InterSystems IRIS Community Edition from the Azure Marketplace
• Configure a small, secure Azure VM
• Connect to IRIS using SSH and the Management Portal
• Reset the default IRIS password and verify that IRIS is running

Prerequisites

• An active Azure subscription (new accounts may have free credits)
• Permissions to create resource groups, VMs, and networking resources
• An SSH client and a private key (.pem) you can store securely
• Basic knowledge of Linux command line

Deployment overview

• Open the IRIS Community Edition listing in Azure Marketplace and click Get it now
• In Azure Portal, choose Start with a pre-set configuration (or Create)
• Configure Basics: subscription, resource group, VM name, region, image, and size (a small VM is usually sufficient)
• Choose SSH key authentication and generate/download the key if needed
• Review + Create, accept terms, and deploy; then Go to resource → Connect → SSH
• First SSH login: run iris password to change _SYSTEM/SYS; start a session with iris session iris
• Management Portal: http://YOUR_VM_IP:52773/csp/sys/UtilHome.csp

Who hasn't been developing a beautiful example using a Docker IRIS image and had the image generation process fail in the Dockerfile because the license under which the image was created doesn't contain certain privileges?

In my case, what I was deploying in Docker is a small application that uses the Vector data type. With the Community version, this isn't a problem because it already includes Vector Search and vector storage. However, when I changed the IRIS image to a conventional IRIS (the latest-cd), I found that when I built the image, including the classes it had generated, it returned this error:

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

i am install the IRISHealth on Mac,however,it met below error,can someone help on this issue:

below is the setup when do install,id/group irisusr is create during install setup.

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...

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!

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.
