Hi Everyone,
We are looking for a way to disable production Business Services concurrently so that the whole process takes shorter amount time than just going sequentially in a loop and disable them one at a time (very slow). This is necessary for us to be able to stop all traffic to IRIS so that no data remains after we perform full production stop.
Thank you!
Hi,
I'm pretty sure I'm not the first one to encounter this, so please share your solution
I'm trying to load a package with 2 dependencies, one of them has 5 dependencies..
is there a better tool / script / wizard for that?
Hi Guys,
I've the below code to build JSON and send it via httpRequest called from business Operation.
But I'm getting this error, which I'm guessing that the formulated JSON doesn't have the correct format, so I was looking to convert the JSONStream to JSON string and try to validate it so see where the JSON is broken, problem is that I'm expecting that there will thousands of records in this JSON so it will hard to go through it, so is there a way to track for error or why this JSON is failing to send
Thanks
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
Scott

I have a question around mapping between different datasets during the HL7 -> SDA3 -> FHIR transformation.
We have a FHIR server which uses the standard ISC HL7->SDA3->FHIR conversion when ingesting HL7 messages. There is the odd requirement to enrich FHIR data from the original HL7 message. due to site specific HL7. Our approach is to extend HS.Gateway.HL7.HL7ToSDA3 with a custom GetSDA method that includes the original HL7 Message ID via CustomPairs.
Hi Guys,
I've the following code:
and I would like to convert the resulting json from JSONStream to JSON string?
thanks

⏯️ 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.

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)
NAMING THINGS RANDOMLY
We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare.
➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.
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.
The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).
Below is an update to the IRIS release calendar for 2026 and an early look at the planned changes for 2027. The key takeaway for 2026 is that maintenance release numbering will differ slightly from prior years.
2026: IRIS 2026.1 maintenance release numbering
This numbering change prepares us for the expanded maintenance cadence planned for 2027.
In v2026.2 (currently available as a Developer Preview), we are adding a feature that can help in a FHIR Endpoint SMART/OAuth authorization - more out-of-the-box flexibility in audience value validation.
One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.
If you are looking for high availability you could use:
a) Kong Traditional Mode: Multiple Node Clusters
b) Hybrid Mode
c) DB-less Mode
Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.
The Interoperability user interface now includes modernized user experiences for the DTL Editor and Production Configuration applications that are available for opt-in in all interoperability products. You can switch between the modernized and standard views. All other Interoperability screens remain in the Standard user interface. Please note that changes are limited to these two applications and we identify below the functionality that is currently available.
To try out the new screens prior to upgrading, you can download the 2025.
In v2026.1 we introduced support for a more robust and real-life secure authorization for your FHIR endpoints.
This is achieved by using SMART on FHIR v2 fine-grained scopes.
READY is right around the corner, and this year the Application Services team from InterSystems will be hosting a Embedded Git Users GroupMeeting during the conference!This will be held Thursday, April 30th during breakfast from 7:30 – 8:30 (breakfast will be served at the meeting room starting at 7:00am).
In case you're planning on deploying IRIS For Health, or any of our containerized products, via the IKO on OpenShift, I wanted to share some of the hurdles we had to overcome.
As with any IKO based installation, we first need to deploy the IKO itself. However we were getting this error:
Warning FailedCreate 75s (x16 over 3m59s) replicaset-controller Error creating: pods "intersystems-iris-operator-amd-f6757dcc-" is forbidden: unable to validate against any security context constraint:
proceeded by a list of all the security context constraints (SCCs) it could not validate against.
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!
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.
The George James Software team is looking forward to going to National Harbor for READY 2026!
As part of the conference, we'll be hosting our Deltanji Source Control User Group:
