I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

Hi Community,

This is my first post in the developer community - would appreciate any feedback!

For testing or demo purposes, you may want to send emails from your Interoperability Production. In this post then I will walk you through connecting an InterSystems IRIS Production to Gmail so you can use it to send emails alerts.

Introduction

HL7 messages often contain multiple repeating segments such as NTE, AL1, OBX, ZTX, DG1, and others. These segments sometimes require individual processing and routing to different downstream systems. This technical paper introduces a configurable template designed to automate the splitting of these repeating HL7 segments, improving message handling and integration efficiency.

Hi, Community!

🔥Does your organization work with HL7® FHIR® resources and need training, now or in the future?

Learning Services is exploring whether to create a new instructor-led course on FHIR support in InterSystems IRIS® for Health and HealthShare® Health Connect.

If you’re involved in approving or recommending training for your team, we’d love your input! Please take a few minutes to complete this short survey.

Your feedback will help us understand both current and future demand so we can build training that supports your needs.

Thanks in advance for sharing your perspective!

👉Take the survey.

hi everyone

we are migrating a legacy script that uploads the files to a SharePoint site through webdav to Health Connect engine.

I wonder if anyone has ever done that, if yes, what did you do to achieve this?

thanks in advance,

Frank

Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

Hi,

The utility returns the desired values from the text and display the multiple values if exists based on starting and ending string.

Class Test.Utility.FunctionSet Extends %RegisteredObject
{

/// W !,##class(Test.Utility.FunctionSet).ExtractValues("Some random text VALUE=12345; some other VALUE=2345; more text VALUE=345678;","VALUE=",";")
 

Building a Sensor Data Demo with Spring Boot and InterSystems IRIS

In the era of IoT and connected devices, sensor data is everywhere—tracking temperature in logistics, monitoring equipment performance, or recording environmental conditions. But capturing, storing, and analyzing this data in real time requires more than just hardware sensors.

Hi all,
I needed to pick up the username from a set of credentials configured for a business operation in an interop production, and it turned out to take a few steps, so I'm sharing my method here, in the dual hope that someone has an easier way to do it, or failing that, that it is useful to someone.
Best,
Otto

InterSystems FAQ rubric

One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Securing IRIS Integrations with Mutual TLS (mTLS): A Practical Guide

In today’s enterprise environments, secure communication between systems is not optional—it’s essential. Whether you're integrating InterSystems IRIS with cloud APIs, internal microservices, or third-party platforms, Mutual TLS (mTLS) offers a powerful way to ensure both ends of the connection are authenticated and encrypted.

This post walks through how to configure IRIS for mTLS and how to validate your certificates to avoid common pitfalls.

Building and Managing HL7 Integrations – In Person October 20-24, 2025 9:00am-5:00pm EDT

Build, configure, and manage HL7® V2 interfaces using InterSystems integration technologies.
This healthcare-focused 5-day course teaches implementation partners, integrators and analysts how to rapidly build HL7 integration solutions.
Students build a production that processes and routes HL7 messages.
Students learn how to work with the pre-built HL7 business services, business processes and business operations to receive and send HL7 messages.
Students also learn how to transform HL7 messages

Following on from JediSoft’s announcement of the general availability of JediSoft IRISsync®, I wanted to show how it can help prevent configuration drift and ensure your failover is always ready. 

When managing InterSystems IRIS production servers, even a minor configuration change can cause significant issues if it’s not replicated in your mirror environments. Often, these differences go unnoticed until your failover environment breaks.

This common, but critical, problem can lead to unexpected downtime at a vital moment and impact your business continuity.

BroadSea - Core OHDSI Walkthrough with InterSystems OMOP

Hi everyone,

My problem was separating HL7 messages by message type.  I had to create multiple File Operations.  So I with custom code I am able to use 1 File Adapter for 1 interface and multiple message types.  I did experiment pulling the MSH 4 out of the raw content to further access dynamic information, but that may open a need for more robust error checking / lookup default actions.

Using the recommended naming convention of "To_FILE_<IntegrationName>"

I decided to use a generic file name and path in the default settings.

I used to mannually test objectscript code in InterSystems Studio.  Does anyone know how to do this is VS Code?

Iris Health dashboard images not loading after first install, getting 404 on /csp paths, is there any setup I am missing?, found this old community post: https://community.intersystems.com/post/debugging-why-management-portal… but the links are outdated, can anyone please guide me to proper documentation. Thanks in advance.

Screenshot attached:

We are excited to announce the general availability of JediSoft IRISsync®, our new synchronization and comparison solution built on InterSystems IRIS technology.  IRISsync makes it easy to synchronize and compare IRIS instances.

IRISsync was voted runner-up in the "Most Likely to Use" category at InterSystems READY 2025 Demos and Drinks.

A huge thanks to everyone who supported us — we’re thrilled to see IRISsync resonating with the InterSystems user community!

Using OpenEHR with InterSystems IRIS

Occasionally. we get questions about using OpenEHR with InterSystems.   Typically, these discussions focus on why and how an organization wants to implement OpenEHR in building applications. Here’s a brief guide:

I would like to learn about the binary and document reference FHIR Resources. For the PDF data stored in those resources. But I think Binary Resource for the Document PDF stored in FHIR, so this resource is best for it. So sometimes Large PDF 15-page (~35md) data converts into base64 then data length is ~50 lac charecters length of base64binary data. this data store in Binary Resource on data field https://www.hl7.org/fhir/R4/binary.html follow this url this resource used in my case. so it's support the 50 lac charecter of the base64 length? This resource can be Insert into IRIS?

A benefit of using Doxygenerate is that Doxygen does more than just HTML output. Tweak the Doxyfile that tells Doxygen what to do and you can easily create a PDF. Our example MARINA application yielded a 524-page PDF. Here's what page 94 looks like:

You can browse the whole file here.

In the screenshot above, notice how we only get details of the superclass that is part of the app (AuditHistory). The primary superclass, %Library.SerialObject, is shown faded and with no details of what BankDetails inherits from it.

Hi,

Is there any way to recover management portal _system user password?

Thanks

Hi Community,

The new video from Global Summit 2019 is available on InterSystems Developers YouTube:

⏯ Reintroducing the Operational Data Store

The healthcare technology market is in strong evolution. Gartner's wave chart for healthcare technologies demonstrates what these technologies are, very well reflected by healthcare.digital. I call this HealthTech See:

These technologies can use InterSystems technologies (ISC Health Tech), see:

Consent Management uses InterSystems Healthshare Stack to do MPI and consent management, see:

I have been walking through this with a few team members and as such I thought there might be others out there who could use it, especially if you work with HL7 & Ensemble/HealthConnect/HealthShare and never venture out past the Interoperability section. 

First, I would like to establish that this is an extension of the already established documentation on importing and exporting SQL data found here: https://docs.intersystems.com/iris20241/csp/docbook/DocBook.UI.Page.cls?KEY=GSQL_impexp#GSQL_impexp_import

We currently have Business Operation that we built to use the EnsLib.SQL.OutboundAdapter so we can make Microsoft SQL Server Stored Procedure calls. The BO is attached to a Java Gateway Service.

Some of our MS SQL Databases have moved from being OnPrem to Azure Cloud. We have started seeing where we are receiving errors on the BO saying that we cannot connect to the Azure Database, but we never receive a Disconnect from the Azure Database.
