InterSystems IRIS for Health™ is the world’s first and only data platform engineered specifically for the rapid development of healthcare applications to manage the world’s most critical data. It includes powerful out-of-the-box features: transaction processing and analytics, an extensible healthcare data model, FHIR-based solution development, support for healthcare interoperability standards, and more. All enabling developers to realize value and build breakthrough applications, fast. Learn more.
A very important feature for HL7 FHIR has been introduced with the release of v2026.1 - the support for SMART on FHIR v2 fine-grained granular Scopes.
This enables you to be much stricter and more accurate in the access you provide to the data in your FHIR repository.
Part of this new support is to refuse requests that don't match the scopes, but an even more interesting ability is to filter the results according to the provided scopes.
I am regularly contacted by customers about memory sizing when they get alerts that free memory is below a threshold, or they observe that free memory has dropped suddenly. Is there a problem? Will their application stop working because it has run out of memory for running system and application processes? Nearly always, the answer is no, there is nothing to worry about. But that simple answer is usually not enough. What's going on?
Consider the chart below. It is showing the output of the free metric in vmstat
Hi Community,

The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS® for Health, and HealthShare® Health Connect is now Generally Available (GA). This is an Extended Maintenance (EM) release.
Hi Community,
Take a look at these new videos in online learning, and get familiar with new features and interfaces in the latest release of InterSystems® products. All videos are also available in the Learning Services YouTube channel.
Plus, check out a video for new ObjectScript developers, and a guide for HealthShare® users upgrading their deployments.
I created a persistent class with all the associated classmethods that will be needed. I am going to use it as a temp storage for data.
Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File.
We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.
Thanks

Hi, Community!
Are you working with large tables? See how partitioning helps you manage and query your data:
This demo walks you through the new Table Partitioning feature in IRIS SQL, explaining what it does and how it works along the way. We'll only use a few dozen rows to prove the concept, but obviously the capability is focused on datasets many orders of magnitude larger.
If you'd like a shorter, higher-level introduction to Table Partitioning, check out the online learning module Managing Tables with Partitioning in InterSystems IRIS
ℹ️ Table Partitioning is included in IRIS 2026.1 as an experimental feature
Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.
Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.

⏯️ AI-Assisted Rare and Complex Disease Detection
This demo shows how InterSystems Health Gateway can be used to pull in outside patient records from networks like Carequality, CommonWell, and eHealth Exchange, creating a more complete longitudinal view in a clinical viewer. That full record is then analyzed by AI to surface potential rare disease considerations with clear reasoning, helping clinicians see patterns they might otherwise miss.

Hi Team,
We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.
Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?
Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.
Thanks,
Ganesh

Hi Community,
Looking for a way to onboard your team with InterSystems IRIS® for Health? Unlock the full potential of this platform by using these InterSystems learning resources. With a mix of online and in-person training, you can support various roles in your organization and equip your team for success.
InterSystems FAQ rubric
There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.
Temporary Globals and the IRISTEMP Database
By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

Hi, every one. Again, it's me!!😀😀
Recently I was trying to organize some learning materials for InterSystems IRIS😆, and realized that the resources are actually quite scattered.🤐
So I put together a list here—grouped by categories—for anyone who:
Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).
If you don’t know where to begin, start here:
While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together.
1. Working with Dynamic Objects:
Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

This past weekend we ran into something odd. When we failed over our mirror from 2022.1.3 to 2025.1.3 the one of the Business Rules that was on what became the Primary (2025.1.3), had a rule within it that was removed back in January. When the Failover occurred, we had to scramble to backup, disable, and remove the Rule that shouldn't have been there.
Both the Data and Code live within the same IRIS.dat that is the main MIRROR database for that Namespace.
If this happened to one Class file, could it happen to others we do not know about?
Hi Community,
In our two preceding articles, we explored the fundamentals of the Interoperability Embedded Python (IoP) framework, including message handling, production setup, and Python-based business components.
In this third piece, we will examine advanced methodologies and practical patterns within the IoP framework that are pivotal for real-world interoperability implementations.
We will explore the following topics:
✅ DTL (Data Transformation Language) in IoP
✅ JSON Schema Support
✅ Effective Debugging Techniques
Collectively, these features help us create maintainable, validated, and easily troubleshootable production-grade interoperability solutions.
Hi Developers!
Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices?
if 10K lines OK? How do you cope with it? Please share?
A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.
A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.
