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!

Hello all,

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

My router is defined as the following:

General Message Routing Rule

The msgClass for said rule is: EnsLib.HTTP.GenericMessage

I have tried a few variants of using a Contains in the condition to check the following: Document.StreamGC.Attributes.

I want to check the Stream for "HITL".  If it contains that, we send downstream.

Is there a way to do this within the condition in the rule?

Is the best solution to instead write a function that rewinds the stream and returns a flag?

Thank you!

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!

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:

READY 2026 is almost here and some people are still deciding whether to go 👀

Imagine a colleague asks you: “Why should I attend READY this year?”

You only get one sentence to convince them.
💙 Read other responses and like the ones that stand out to you. The comment with the most likes will receive 500 bonus points on Global Masters.

Drop your best argument below 👇

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

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.

Please, provide Code example to build a %Library.DynamicObject or a %Library.DynamicArray from Resultset followed by converting to JSON

The InterSystems Ready 2026 Conference  is approaching fast — it's a great time to prepare and check your knowledge before attempting one of the Certification exams onsite .

InterSystems certifications aren't easy: you need to practice with questions aligned to the real exam objectives.

exam-prep.es is a free platform built for exactly that: practice, identify weak spots, and show up better prepared.

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.

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"

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).

Hi Community,
