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.

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.

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 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.

Hello Community!

We're pleased to invite you to the upcoming webinar in Hebrew:

👉Getting Started with OAuth 2.0 on InterSystems 👈

📅 Date & time: March 25th, 3:00 PM IDT

I would like to understand the mechanism of "How data is written to the IRIS Database and in what sequence data is written to Journal, WIJ and IRIS database"

Is it possible to run a test case by classname instead of loading it from a directory?

I need to skip any directory loading completely since the directory with the source code does not exist.

Hello,

I have problem to get working my web application in IIS. On apache just works fine.

I had an app in wwwroot called test, there is index.html file where is tag

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.

Issue

In the versions specified above, an instance may fail to start or may hang during operation if the database cache is greater than or equal to 2,097,152 MB (2 TB).

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 🧑‍💻

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.

Hello all,

I have a EnsLib.HTTP.GenericMessage inbound from a webhook with a GC stream.

My router is defined as the following:

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

Hi community,

I've been working on a side project that I'd love to get some eyes on: a ground-up rebuild of the classic IRIS Production Monitor using a modern web stack. The existing ZEN/CSP-based portal does the job, but I wanted to explore what a contemporary, real-time version of it could look like.

What it is

A standalone Angular web application that connects to any Interoperability-enabled IRIS namespace and gives you a live view of your production — services, processes, operations, queues, event log, and message traffic — all in one screen.

As part of the new Interoperability UI wave (see what was new in 2025.1, and 2025.3 by @Aya Heshmat), v2026.1 which is available already as a Developer Preview, and this could be a reason for you to give it a ride - will be shipping the new UI for the Message viewing and searching, including Visual Trace (and other UI goodies).

He's a quick teaser:

I may have mentioned this before: I believe the Visual Traces, these sequence diagrams with full content of each step, are a fantastic feature of the IRIS Data platform! Detailed information about how the API works internally, as a visual trace, can be very useful for projects on the IRIS platform. Of course, this applies when we are not developing a high-load solution, in which case we simply don't have time for saving/reading messages. For all other cases, welcome to this tutorial!

If you have ever dug through a large IRIS namespace looking for where a particular string, method call, or pattern was used, you know the pain: there was no built-in way to do a grep-style search across your server-side ObjectScript code from VS Code — at least not without jumping through some hoops.

That is what ObjectScript Search fixes.

Try it today with a simple install from the VS Code Marketplace. If you don't like it, uninstalling is just as easy. But I think you will like it — it is a huge quality-of-life improvement for anyone doing ObjectScript development in VS Code.

We are trying to track down significant growth within our Namespaces, one big culprit is Ens.AppData (EnsLib.SQL.Snapshot). 

Within many of our BPL's we use EnsLib.SQL.Snapshot to return Results from External SQL Stored Procedures or Query's. The same EnsLib.SQL.Snapshot context variable is used for many of these calls within a BPL. 

Is there something we should be doing at the end of the BPL to ensure that EnsLib.SQL.Snapshot gets cleaned up and purged from Ens.AppData?
