Hi Community,

We're super excited to share that we’ve just launched a new free, interactive tutorial designed especially for those who are new to InterSystems IRIS and looking for a clear, practical introduction to its core concepts.

🧑‍🏫 Data Models of InterSystems IRIS 🧑‍💻

Why This Integration Matters

InterSystems continues to push AI capabilities forward natively in IRIS — vector search, MCP support, and Agentic AI capabilities. That roadmap is important, and there is no intention of stepping back from it.

But the AI landscape is also evolving in a way that makes ecosystem integration increasingly essential. Tools like Dify — an open-source, production-grade LLM orchestration platform — have become a serious part of enterprise AI stacks.

We have an HL7 feed that contains Lab Results. Each message contains a set of results, identified by a LabReportId. Some LabReportIds can get more than one message / set of results - these are updates, as new results become available, and must be processed in order. Results for different LabReportIds can be processed in any order.

As each message is used to build a PDF, which takes time, we want to run these through a production where the key business process has a Pool Size > 1, while still ensuring that messages for each LabReportId are processed in order.

Anyone up for a round of golf?

Are you fed up of making a machine write code for you? Do you miss thinking through problems yourself? Then you are in luck, this round, I propose adding the rule of no AI use. obviously its a game of honor with no prize, so I shan't be enforcing this, but you'll know...

I have installed IRIS community edition on a local directory in Redhat Linux 9.4.

Created a 10G database on a separate mount point directory  which comes out of a storage volume of 50G.

Also placed Journal and WIJ on 2 separate mount point directories  which comes out of two different storage volume of 50G each.

I want to take a snapshot and recover the snapshot on a secondary host and check the consistency of the database. 

As Storage snapshot will be taken, only Data, Journal and WIJ file placed on Storage volumes will be snapshotted.

Is there any Cache setting that needs to be checked while configuring IRIS Community Edition 2025.2 and does it impact WIJ recovery.

Also I have kept Database, WIJ and JOURNAL on the same snapshot group with Consistency . Is it the recommended settings? Am I getting the WIJ mismatch error due to this setting?

Please, provide Code example to build a %Library.DynamicObject or a %Library.DynamicArray from Resultset followed by converting to JSON

I am currently managing environments running InterSystems IRIS and Caché on Windows servers.

I’m reviewing storage optimization best practices and I have a question regarding a specific Windows drive setting: "Allow files on this drive to have contents indexed in addition to file properties."

Based on my research, everything indicates that it is better to disable this option, especially on drives used by databases. However, I couldn't find a specific "official" stance in the documentation explicitly mentioning this checkbox.

Hi Community,

Configuration differences between environments are not always mistakes, but they should always be intentional and governed. 

We're excited to announce that version 3.6 of JediSoft IRISsync® is now available, bringing enhancements designed to give teams more control and visibility when managing configuration settings across multiple IRIS instances.

What's new in IRISsync 3.6: 

• Accepted differences - Mark intentional configuration differences to provide further clarity in comparison results.

Hi 

Is there a sample that I can use to create a simple alert code, and do I need to set up or pay a service provider? 

Thanks

I am stuck at a crossroad and was wondering if I could get a second pair of eyes to help with a query that I am sending from a Task to a Service to process some data.

I have a Linked Table (view) that points back to a MS SQL View that I am trying to query. However, my execution keeps either failing or not returning any rows. When I take the SQL Query and execute it within the Management Portal I get results, however Cache is not seeing it when trying to execute this code.

I had configured the environment as follows:

OS: Redhat Linux 9.4

IRIS 2025.2 installed on local directory

IRIS Database: One LVM is created with 20 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that

Primary and Alternate Journal: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

WIJ: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

So Data, WIJ and Journal is mounted on 3 separate mount point.

Role Summary

We are building a federated healthcare data platform enabling secure, privacy-preserving research across hospitals and medical devices in multiple regions.

We are seeking a Team Lead for Development who will own the technical delivery and execution of this platform — translating architectural direction into implemented systems and coordinating multidisciplinary engineering teams.

This role sits between architecture design and operational deployment.

I am trying to create a task that has a variable property that a user can specify DaysBack but it keeps coming up blank when I ask the system to get the date as of DaysBack from the CURRENT_DATE. Can someone tell me why I am not getting a value back in my tDate variable?

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition
{

Parameter TaskName As STRING = "OSU - Workday Termination Update";

Property DaysBack As %Integer [ InitialExpression = 1 ];

Method OnTask() As %Status
{
	Set tSC=$$$OK
	#Dim tException as %Exception.

Hello everyone,

I am André from MedVertical. We are exploring InterSystems-native ways to operationalize continuous FHIR conformance: repeatable regression runs, baseline/delta comparisons, and evidence-style reporting to detect drift after releases and IG changes.

In many FHIR implementations, validation is done “point-in-time” in pre-prod, but conformance degrades in production due to IG/profile updates, terminology changes, mapping evolution, upstream releases, and configuration drift.

If one of your packages on OEX receives a review, you get notified by OEX only of YOUR own package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you made a major change and expect a changed review, just let me know.

Hello!

I am requesting feedback on the usage and experience of the Schema Viewer feature available in Interoperability-enabled products (IRIS, IRIS for Health, Health Connect). This feature is accessible via Interoperability > Interoperate. 

Some questions to jog your discussion/comments below:

1. What's one enhancement that would drastically change your experience or enable faster schema configurations?
2. If you are not a user of this feature (but need to create custom schemas/view your schemas), why do you not use the schema viewer?

I am issuing "iris freeze <instance_name> to freeze the instance. I want  confirmation that no IO is going to the database so taht I can take a snapshot.

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?
