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.

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).

Welcome to the monthly recap of updates and releases to VS Code and InterSystems-related extensions relevant to IRIS developers. 

If you're migrating from InterSystems Studio to VS Code, or want to deepen your knowledge check out the VS Code training courses from George James Software: georgejames.com/vscode-training.

VS Code version 1.110
Kitty graphics protocol in the Terminal - The integrated terminal now supports the Kitty graphics protocol, allowing for high-fidelity image rendering directly in the terminal pane.

IPM version 0.10.6 was released on February 24th, 2026. This version is mostly bug fixes, but does add the -export-python-deps flag to the package and publish  commands to include Python dependencies with the IPM module itself. As usual, you can check it out on the GitHub page or through the Community Registry. 

Here's the complete changelog:

Added

• #1024: Added flag -export-python-deps to publish command

Fixed

• #996: Ensure COS commands execute in exec under a dedicated, isolated context
• #1002: When listing configured repositories, only show the TokenAuthMethod when a token is defined.

Hi, Community!

Working with large volumes of data? See how streams can help:

Storing Large Amounts of Data with Streams in ObjectScript 

Hi everyone,

I am trying to configure a FHIR Server to authenticate against an external OAuth server using the OAuth FHIR Client Quickstart, which is available in the newer versions of InterSystems IRIS for Health.

During the configuration process I am encountering an issuer validation error.

I have already verified the issuer URL, and it exactly matches the value returned by the OAuth server’s OpenID configuration endpoint (.well-known/openid-configuration).

Example:

Issuer configured in IRIS
https://login.microsoftonline.com/{tenant-id}/v2.0

Issuer returned by the OpenID configuration
https://login.

We have an HL7 feed that contains Lab Results. Each message contains a set of results, identified by a LabReportId. Some LabReportIds can get more than one message / set of results - these are updates, as new results become available, and must be processed in order. Results for different LabReportIds can be processed in any order.

As each message is used to build a PDF, which takes time, we want to run these through a production where the key business process has a Pool Size > 1, while still ensuring that messages for each LabReportId are processed in order.

I had configured the environment as follows:

OS: Redhat Linux 9.4

IRIS 2025.2 installed on local directory

IRIS Database: One LVM is created with 20 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that

Primary and Alternate Journal: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

WIJ: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

So Data, WIJ and Journal is mounted on 3 separate mount point.

I am currently managing environments running InterSystems IRIS and Caché on Windows servers.

I’m reviewing storage optimization best practices and I have a question regarding a specific Windows drive setting: "Allow files on this drive to have contents indexed in addition to file properties."

Based on my research, everything indicates that it is better to disable this option, especially on drives used by databases. However, I couldn't find a specific "official" stance in the documentation explicitly mentioning this checkbox.
