In the previous article, we used pyprod to create production components while relying on the UI for production configuration. That same production can now be defined entirely in Python:

from intersystems_pyprod import Production, ServiceItem, ProcessItem, OperationItem

iris_package_name = "HelloWorld"

class MyProduction(Production):
    services = [
        ServiceItem(
            "MyServiceName",
            "HelloWorld.MyService",
            host_settings={"target": "MyProcessName"},
        )
    ]
    processes = [
        ProcessItem(
            "MyProcessName",
            "HelloWorld.MyProcess",
            host_settings={"target": "MyOperationName"},
        )
    ]
    operations = [
        OperationItem("MyOperationName", "HelloWorld.MyOperation")
    ]

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.

On save the ClassMethod:

ClassMethod create() [ Language = python ] {

 print("python") 

}

it has received the error : Compilation started on 06/03/2026 02:15:21 with qualifiers 'cuk /multicompile=0'

 ERROR #7802: Worker job/s '1078:17' unexpectedly shut down in group '#Default:(9119826733444):0'.

 ERROR #7802: Worker job/s '1078:17' unexpectedly shut down in group '#Default:(9119826733444):0'.

Hi all,

I'm working on a DICOM router in InterSystems IRIS, based on the workshop-iris-dicom-interop (https://github.com/intersystems-ib/workshop-iris-dicom-interop) example on GitHub. I'm using EnsLib.DICOM.Process to route incoming images to different PACS destinations, where the target system is decided at runtime via a database lookup.

I've run into two issues I'd love some guidance on:

1. Dynamically changing the destination without disrupting transactions

Right now, if I want to send to a new PACS target, I'd need to add a new Business Operation and call

In the previous IoP article, I showed how IoP can expose Python messages to DTL by generating JSON schemas. That is useful when the message is primarily a Python object and we want the IRIS tooling to understand its structure.

This time, the direction is a little different.

Starting with IoP 3.7.1, a PersistentMessage can now be a native IRIS message body class. The Python class is still the source code you write, but the generated IRIS class extends Ens.MessageBody

READY is right around the corner, and this year the Application Services team from InterSystems will be hosting a IPM Users GroupMeeting during the conference!This will be held Wednesday, April 29^th during lunch from 12:30 – 1:30 (lunch will be served at the meeting room).

IPM version 0.10.7 was released on May 29th, 2026. As usual, you can check it out on the GitHub page or through the Community Registry.

Highlighted Features

Utility Scripts iriscli and ipm

IPM is now bundled with two convenience scripts that are runnable from a standard terminal. iriscli launches an interactive IRIS terminal and runs IPM commands directly. These are automatically installed to both ~/.local/bin/ and , so they work inside and outside of containers (Unix/Linux only).

Examples:

I have several Business Operations that share similar behavior, like building HTTP headers or parsing a specific response format. In C# I would extract this into a service class or a base class. What is the recommended way to do this in IRIS? Should I use a utility class, a common superclass, or is there another pattern the community prefers?

I have a Business Process that needs to call an external API that may take several seconds to respond. I'm worried that keeping the BP blocked waiting for the response could affect the overall Production throughput. Is there a recommended pattern for handling async calls inside a BPL or custom BP class to avoid this kind of bottleneck?

Hey everyone.

My team and I have a rare opportunity to start from scratch, and I am keen to know what things others that have gone through a similar process did differently. Obviously there's the immediate benefit of losing any technical debt that has built up over 10+ years of an ever changing environment along with many organisational changes and merges, but I'm thinking about the things that we can do to make life a lot easier for the next 10+ years.

Hi, we are trying to adapt the solution to use the IKO but we have problems deploying the webgateway on our company clusters, our clusters requires to have a specific definition on the securityContext due security concerns, it's possible to set those values trough the IrisCluster CRD? or we cannot use it from it? Should I open a WRC to handle this?

create Pod iris-webgateway-0 in StatefulSet iris-webgateway failed error: pods "iris-webgateway-0" is forbidden: ValidatingAdmissionPolicy 'prevent-root-run' with binding 'prevent-root-run' denied request: Containers should run with securityContext.runAsNonRoot or securityContext.runAsUser != 0.

I'm approaching the need to send notifications through a Microsoft Exchange or Gmail servers. however my last foray into this, I was blocked due to an issue inside my SSL certificate is what I thought after the attempt.

So my attention will be on trying to match the cryptography in the SSL certificate I produce compared to the mail server I'm trying to use.

Has anyone else had an issue with this approach? My other option is Amazon SNS potentially. I do have a functional MS Teams channel for alerts, and can make different notification channels as well.

Any help or insights are appreciated.

HealthShare Unified Care Record Fundamentals – In Person* June 22-26, 2026

*Please review the important prerequisite requirements for this class prior to   registering.

• Learn the architecture, configuration, and management of HealthShare Unified Care Record.
• This 5-day course teaches HealthShare Unified Care Record users and integrators the HealthShare Unified Care Record architecture and administration tasks. 
• The course also includes how to install HealthShare Unified Care Record. 
• This course is intended for HealthShare Unified Care Record developers, integrators, administrators and managers.

In our previous article, we explored the basics of unit testing in IRIS and the ways to apply it to a REST API. We even figured out how to test logic before finalizing network configurations and authentication, allowing us to focus solely on testing the API contents. Today, we will build upon that foundation and elevate our unit testing strategy by using another tool: %Populate .

At first glance, the %Populate class appears to be very simple. You can create a class that extends both %Persistent and %Populate and inherit a Populate method designed to generate randomized records.

Abstract

Common Table Expressions (CTEs) provide a structured framework for defining reusable intermediate result sets within SQL statements. InterSystems IRIS implements CTEs via the WITH clause, enabling clearer query composition and modular analytical processing while remaining fully integrated with the IRIS cost-based optimizer.

This article explores the semantics of CTEs in InterSystems IRIS, explains their interaction with query optimization, discusses appropriate deployment scenarios, and presents executable examples illustrating practical patterns for production environments.

We have a long running InterSystems Engine with an Interface Development Team.  We have implemented basic interface and code development processes using mostly manually created helper tasks and functions.
We are looking to upgrade these processes by installing and starting to use Embedded GIT in our DEV spaces first.  We will not use it to deploy changes to PRODUCTION at first, keeping our same current process that the team is very comfortable with.  
We plan to start by using the BASIC mode in GIT, to avoid confusion over multiple branches and other version control functions.

What tools or techniques do you use to debug a Production during development? I know the Management Portal shows the message queue and event log, but I'm wondering if there are better ways to trace a message through the full BS > BP > BO flow without relying only on logs.

Hello,

Looking for some additional help, maybe someone who has experience with this before, in setting up and configuring the Web Gateway with Kerberos.

Have read through the documentation (at the link below) and it's a good start but seems there are some details missing, or I'm not clear on. 

Questions: 

• Is there a external enterprise Kerberos server required, or is this set up contained within the local server?
• Is there a step-by-step instructions on what to do and configure to successfully complete this?
• Are there there config changes necessary for Apache?
