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 everyone,

I am trying to configure a FHIR Server to authenticate against an external OAuth server using the OAuth FHIR Client Quickstart, which is available in the newer versions of InterSystems IRIS for Health.

During the configuration process I am encountering an issuer validation error.

I have already verified the issuer URL, and it exactly matches the value returned by the OAuth server’s OpenID configuration endpoint (.well-known/openid-configuration).

Example:

Issuer configured in IRIS
https://login.microsoftonline.com/{tenant-id}/v2.0

Issuer returned by the OpenID configuration
https://login.

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... 

Challenge:

Create a function which takes a string as a parameter, and returns the length of thelongest sequence of alternating consonants and vowels. The sequence is broken by having two vowels or two consonants in a

Let’s see who can make READY 2026 impossible to resist.

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.

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.

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 🧑‍💻

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

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.

I have a global with multiple nodes : 

^A("ABC") = ""
^A("DEF") = ""
^A(123) = ""

How to create a new single node in that global, in a way it's always at the end of the global (eg: this will be the very last node being enumerated)

I end up with this code but maybe there is a cleaner and simpler approach : 

set ^A($char(65535)) = "" //should be bigger than any character inserted
set ^A($char(255)) = ""   //some systems does not seems to support >255 characters, this might be safer

I only need to write it once, this code is not intended to be used in a loop or something, just to add something at

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.
