The problem

How many times have we migrated an IRIS Instance to another machine, maybe even another version, and after a few days realized we forgot that one SSL Configuration critical for a Business Operations to work? Or maybe a credential, or a lonely class in a package by itself?

The solution

The simple solution is to make a checklist¹. A checklist of the entities we have to move. But simple checklists on Word documents are often forgotten, or just ignored.

Announcement Mariam Makhmutova · 9 hr ago

Hi Community,

Out of almost 200 applications, 26 selected teams will begin a 3-month fully virtual journey at Caelestinus. The cohort brings together pre-seed to seed stage startups from across the globe, spanning the United States, South America, Europe, South Korea, and Singapore.  

During the program, teams will enhance their solutions by building in interoperability, gaining an understanding of key digital health standards, and transforming them using InterSystems IRIS for Health and FHIR Server with the help of InterSystems experts.

We're pleased to invite everyone to watch the Caelestinus 2026 Kickoff Event streaming, where you can discover which teams were selected and learn about their innovative ideas.

Please watch the streaming via www.caelestinus.tech starting at 9 AM ET / 2 PM CET on March 25th 2026.

You can also watch the recording of the opening event here.

Question Alexandra Stuck · Mar 18

 Hi everyone,

I’m currently working with InterSystems IRIS and handling large datasets where some queries are starting to take longer than expected.

So far, I’ve tried basic indexing and reviewing query structures, which helped a bit, but I still feel there is room for improvement. My goal is to reduce response time, especially for frequently used queries in a production environment.

Hi Community!

We’re building a series of short, hands-on Instruqt tutorials to help newcomers get up to speed with InterSystems technologies faster and more effectively. To kick things off, we’ve just released a new tutorial, “Data Models of InterSystems IRIS,” covering the fundamentals of the IRIS multimodel approach. This is exactly the type of focused, concise, practical learning experience we want to expand. And this is where you come in!

We’d love to hear your ideas for other tutorial topics to help developers new to InterSystems IRIS take their first steps with confidence. Please welcome the new sweepstakes:

Question Scott Roth · Mar 18

While reviewing our Orphan messages, we noticed that there are some Orphans that look like they are the start of an HL7 message.

MSH|^~\&

Since this does not link to any Message Header, and most of the information in EnsLib_HL7.Message is NULL, is there a way to track down what Object maybe creating these so we can nip it in the bud.

Only way that I know of is to go through each of our Schema's and make both the MSH and Encoding Characters optional.

I created a new repo called ipm-module-budget from https://github.com/intersystems-community/intersystems-iris-dev-template template.

I cloned the repo to an EC2 instance in AWS. When I try to build image, I see this error:

Already included in SystemPerformance

There are nfs disk commands (including nfsiostat) included with SystemPerformance, but disabled by default. Enable them by running:

$$Enablenfs^SystemPerformance()

Doing so will add the following nfs commands, for example, on Linux:

  1. /usr/sbin/nfsstat -cn
  2. /usr/sbin/nfsiostat [interval] [count]

Ensure the commands are installed and runnable from the OS :)

This can be subsequently disabled via $$Disablenfs^SystemPerformance()


Adding a generic command to SystemPerformance

Adding an arbitrary OS tool creates a "user" command under ^IRIS.

Question Jesse Jones · Mar 16

I have an issue and can't seem to find the problem.

Issue

 In some namespaces i get a 403 Page not Found error for healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.namespaceSelect.cls ; healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.finderDialog.zen  && healthconnect/csp/healthshare/[NAMESPACE]/_CSP.UI.Portal.About.zen

 

Iris setup

It is currently configured in a mirror group and on the other mirror-member i don't encounter the issue. (I have checked if it was because of the member-type Primary and Backup). 

The user that I am using has the %All role.

Question Luis Gallardo · Mar 17

We are trying to run the HS solution inside of a container, but we are getting the following errors un start up
03/17/26-10:19:05:108 (1386) 1 [Generic.Event] Cannot lock /usr/irissys/mgr/hslib/ err(13): will try accessing readonly
03/17/26-10:19:08:174 (1386) 1 [Generic.Event] Cannot lock /usr/irissys/mgr/enslib/ err(13): will try accessing readonly

I understand that those databases should be mounted as read only don't needing the lock, any idea how to fix it? or where should I look to configure it correctly?
Thanks!

Announcement KC Lu · Mar 16

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.

What Changed

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.
