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.

Hi Community,

A big perk of attending InterSystems READY 2026 (April 27–30) is the chance to talk to our experts!

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).

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.

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:

There are lessons we learned from developing and maintaining code for interoperability components within a healthcare institutional environment.

The plane is already flying

Be prepared to rebuild, improve, extend, and fix the plane mid-flight.
 

Maintenance windows for hospital systems are often very limited, with some required to be operational 24/7. While the critical health systems such as imaging modalities or registration kiosks — or at least their critical functions — must operate autonomously, efficiency and usability may be compromised when interoperability components malfunction.

Hey Developers,

Thank you for being part of the InterSystems Developer Ecosystem! 
We truly appreciate your participation across the Developer Community, Open Exchange, Global Masters, and the Ideas Portal.

Each year we run a short survey to understand how we can improve our platforms and better support developers like you. Your feedback helps us shape the future of the ecosystem.

Please take a few minutes to complete the survey:

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.

Hi, Community!

Welcome to InterSystems Online Learning 

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?

Hello everyone, thanks for reading this question.

I am currently working with Ens.Alerting.ManagedAlert in an interoperability production and I am using the alert suppression mechanism to avoid generating duplicate alerts within a defined time window (for example, 30 minutes).

The configuration works correctly in terms of preventing duplicate alerts from being generated, but I have a question regarding observability.

When an alert is suppressed during the configured time window, I can see log messages such as:

        "Managed alert not created for AlertRequest with ID 'XXXX' due to rule 'Rules.

How can I create a Task that tells a Ens.BusinessService to execute its SQL query using the EnsLib.SQL.InboundAdapter?

So far I have come up with

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

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

Method OnTask() As %Status
{
    try{
        // Call BusinessService
        set tSC = ##class(Ens.Director).CreateBusinessService("OSU.DataSource.Workday.TermService",.tService)

        if $IsObject(tService){
            set inputMessage = ##class(Ens.StringContainer).

Background

Emergency Medical Services (EMS) teams often arrive at the emergency department with patients whose demographics are incomplete or unknown—no medical record number (MRN), no confirmed name, and sometimes no date of birth. Yet EMS transportation notes still need to land in the correct chart.

To support safe and reliable documentation, EMS agencies, third-party integration services, and hospital integration teams build secure interfaces that exchange identifiers and clinical messages.

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.

I’m trying to find a way to manage globals from our Java application. We have two separate features:

• Managing tables normally using SQL

• Managing globals, since some globals exist without class or table definitions

Cache version : Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.1.1 (Build 108U_SU), Thu Jul 7 2016 09:39:04 EDT

I tried to retrieve the globals tree, update node values, and append nodes using SQL by calling stored procedures, but I couldn’t find any procedures for adding, updating, or deleting nodes.

I also tried using cacheextreme.jar to access the globals API directly.

How to execute a stored procedure in a remote DB2 database?

Hi Everyone,

I want to access a stored procedure in a remote DB2 database. The stored procedure in question is linked and receives a numeric value, returning a cursor with N number of rows. Sometimes the number of rows reaches hundreds of thousands, so I need to apply pagination.

I've been reading about the %ScrollableResultSet library, but it doesn't allow me to call a stored procedure.

Here's part of the code:
Set pValor=12345678
Set callSql="CALL Paquete.ClaseSpRemoto(?)"
Set rs=##class(%ScrollableResultSet).
