Okay… first things first - sorry it took me so long to write this up. There was just too much happening, too many conversations, too many photos, too much travel and honestly… too much excitement to sit down and write right away.

READY 2026 started the way it always does, with that unique mix of anticipation and energy in the room. Look at these excited faces!

Question Yuriy Borokhov · 10 hr ago

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!

Question Touggourt · May 5

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

Question Davi Massaru Teixeira Muta · 9 hr ago

How can I remove UNIQUE NOT NULL from an existing column via DDL?

I currently have a table in production that was originally created via DDL, where the column was defined as UNIQUE NOT NULL:

CREATE TABLE database.Books ( ID %Library.UniqueIdentifier PRIMARY KEY, TagExternal VARCHAR('') UNIQUE NOT NULL,  

I now need to change this column so that it is no longer UNIQUE and no longer NOT NULL, making it equivalent to:

TagExternal VARCHAR(''),

As promised, here comes the second part.

But before I begin, here's the view from my hotel window in Boston, where I went before the READY. And a grand building on the right is the office of InterSystems. Not bad, ha?

Anyway, after getting some sleep after the Demos and Drinks the day before, we were back at it the next day, which started with more keynotes.

Question Scott Roth · Apr 23

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

Question Luis Gallardo · 16 hr ago

Hi! 
We are working on containerizing our IRIS product. We want to extract the message log that is shown in the terminal, but if possible, we want to format the output as JSON and include some extra fields from the instance to enhance our monitoring. Is this possible?
Any guide or example about it?
Thanks!

Question Glenn Elliott · 17 hr ago

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.

Question John Murray · Feb 27

I am configuring a set of Linux (RHEL 9) servers to operate as an IRIS 2025.1 mirror set. Mirroring traffic is using TLS, so each IRIS server has the necessary TLS configurations. However installation of ISCAgent on the dedicated arbiter host didn't make any mention of TLS or certificates. Nor did I find anything about this when searching IRIS documentation.

Am I missing something? Does the traffic between the IRIS hosts and the arbiter host use TLS? Should I be installing any certs on the arbiter host to facilitate secure communication?

Abstract

Solar irradiance forecasting is critical for grid stability in photovoltaic (PV) power plants. This article replicates and extends the methodology of Lara-Benítez et al. (2023) "Short-term solar irradiance forecasting in streaming with deep learning" replacing the original offline simulation with a fully operational streaming pipeline built on InterSystems IRIS. We leverage IRIS Interoperability Productions as the streaming backbone, Embedded Python to run MLP, LSTM, and CNN deep learning models, and IntegratedML as an AutoML baseline.

In InterSystems IRIS, when you compile a persistent class, you automatically get a SQL table. Sometimes, there are situations that require having a slightly (or not so slightly) different names/options in SQL compared to Object model. Here are some of the settings that you can change to make it happen.

Class-level settings 

They define the "Face" of your class when it appears as a table in the SQL catalog.

SqlTableName allows you to change the name of SQL table that holds objects from your class. This is especially useful, when your class name uses reserved SQL words in a name, e.g. Group.

Despite the fact that LOCK (docs) is a foundational part of InterSystems IRIS, responsible for concurrency, there is not a lot of discussion on the Developer Community about it. Which is understandable, considering it's stable and fairly low-level command. In this article, I will show a simple example of how to use locks with interoperability.

When managing critical healthcare data through an integration engine you want to know the moment a queue starts backing up or a service drops. 

Unfortunately, this usually leads to an email inbox stuffed full of notifications that can sometimes seem impossible to maintain.

Well, I’ve not solved that problem. 

But I have created something that could help...

Question John Murray · May 4

As an experiment in agentic coding in ObjectScript I'm using VS Code to try and create an implementation of an SFTP server.

SFTP is built on top of SSH, so the first phase involves implementing an SSH server. While working on the KEX part of that the agent (using GPT-5.3-Codex) reported:

  1. IRIS has what we already need for signing and hashing: RSASHASign, RSASHAVerify, RSAGetLastError, SHAHash, SHA1Hash, SHA3Hash.
  2. It does not list a Diffie-Hellman key exchange or modular exponentiation API in %SYSTEM.Encryption.

It then offered these options:

  1. Keep using IRIS APIs for cert/key/sign/hash.

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.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).
