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.

I created a table profile dashboard on Power BI, but I wonder if is possible to do it in Iris by creating a class.

Hi Community,

Preparing for InterSystems Certification examsrequires more than reading documentation. It calls for focused practice aligned with real exam objectives.If you are planning to validate your expertise in HL7, SQL, System Administration, or Development, structured preparation can make a significant difference.

🧑‍🏫 Exam preparation platform

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!

Hello to all the esteemed members of the InterSystems developer community in Spanish!

Although I often consult the developer community and have occasionally left a question here, this will be my first article, and what better occasion to do so than by participating in the 3rd technical article contest.

The topic I will cover in this article is the different tools that InterSystems IRIS provides us to optimize both the databases and the queries we run, as well as the new types of storage and data.

Hi Communtiy,
I am a begineer who is working and trying to understand Intersystems. I am developing an Ensemble interface which receives a XML message and converts it into HL7 format without using enslib.HL7 classes.

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 row.

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?

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.

Hi Community!

Welcome to Issue #27 of the InterSystems Ideas newsletter! Let's look at the latest news from the Ideas Portal, such as:

✓ General Statistics
✓ New sweepstakes!
✓ Recently implemented ideas by InterSystems

I have a json object coming in on a service with a field that has "NaN" as its value.

"ReferralInOutOfNetworkCd": "NaN",

In my DTL, I do a straight copy. yet what goes outbound is NaN, without being wrapped in double quotes

"consulting_provider_network_ordering_rd":NaN,

Has anyone experience this?  If so, did you find a way to fix or work around it?

Hi Community,

We're super excited to share that we launched another free, interactive tutorial designed to give you a little taste of InterSystems Data Studio.

🧑‍🏫 Introduction to InterSystems Data Studio 🧑‍💻

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.

 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.

Hey Community!

Have you attended one of the Global Summits or a previous READY 2025? We’d love your help to inspire others to join InterSystems READY 2026!

We’re inviting community members to record a short video (less than 1 minute) answering one or more of these questions:

• What did you find most valuable about attending?
• What surprised you?
• Why should others join READY 2026?
• Who would benefit most from attending?

Your authentic perspective helps future attendees understand the real impact of these events, beyond the agenda.
