Hey Developers,

Get an introduction to Apache Kafka, a popular event-streaming platform, and see a demonstration of the upcoming Kafka integration with InterSystems IRIS Interoperability:

I combined @Rodolfo Pscheidt https://github.com/RodolfoPscheidtJr/ollama-ai-iris with some files from @Guillaume Rongier https://openexchange.intersystems.com/package/iris-rag-demo.

My own project is https://github.com/oliverwilms/ollama-ai-iris

I can run load_data.py and it connects to IRIS (same container).

When I try to run query_data.py https://github.com/oliverwilms/ollama-ai-iris/blob/main/query_data.py , it cannot connect to ollama:

ConnectionError: Failed to connect to Ollama. Please check that Ollama is downloaded, running and accessible.

I wonder if I need to add in query_data.py, how it

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:

As we all know, InterSystems is a great company.

Their products can be just as useful as they are complex.

Yet, our pride sometimes prevents us from admitting that we might not understand some concepts or products that InterSystems offers for us.

Today we are beginning a series of articles explaining how some of the intricate InterSystems products work, obviously simply and clearly.

In this essay, I will clarify what Machine Learning is and how to take advantage of it.... because this time, you WILL KNOW for sure what I am talking about.

Hi,

What is the best way to develop Angular applications while working with CCR?

CCR peer reviewers require submitting Angular source files, so that a peer reviewer has something readable to review. However, CCR environments require that you deploy compiled Angular applications to them.

I think I found my solution but I'm trying to understand better why it works. Forgive me as my descriptions here may be scattered but I'm trying to piece the puzzle together.

Scenario: I've found there are times when I make a request using a %Net.HttpRequest object and as I'm debugging and stepping through via the debugger in VSCode, if I try to access an object in the 'variables' menu, sometimes when I click that little expand button it will just spin and never load what's in the object to the viewer.

Hi Guys,

I'm a newbie that doesn't know much about integratedML and looking for a first push into it, I've setup VSCode with my IRIS 2024.3 running in Linux and my understanding is that we can create models using SQL, so first, do I need to setup a specific environment where I can run my SQL commands to create & train Models or just using SMP, and do I need to install or enable Python ..etc things required to setup the environment?

Then if there are easy samples or training materials on how to create, train & deploy my model?  

Thanks

Hi Community,

How Can I do to return ID when I call %JSONExport()?

Prefer not to read? Check out the demo video I created:

I've conducted some tests using different InterSystems IRIS Community Edition container images, which I pulled from https://containers.intersystems.com.

During this process, I noticed some inconsistencies that I’d like to clarify:

• The tag latest-preview pulls: InterSystems IRIS Version 2025.1.0.204
• The tag latest-cd pulls: InterSystems IRIS Version 2024.3.0.217
• The tag 2025.1 pulls: InterSystems IRIS Version 2025.1.0.223

This behavior was a bit confusing to me, especially since latest-preview does not point to the most recent 2025.1 build.

Could someone please confirm if this is the

I was wondering if someone could help me. In the past I have been able to call external Stored Procedures through a SQL Outbound Connection and have them return me the EnsLib.SQL.Snapshot to use within a BPL to extract data.

But this time instead of using a SQL Outbound BO to make the Stored Procedure call, I decided to create a Linked Stored Procedure through the %JDBC_Server to point to the Stored Procedure out on MS SQL.

However, I am struggling to get the code just right to return the Column value from the Linked Stored Procedure.

set result = ##class(EnsLib.SQL.Snapshot).%New()
 set result

The InterSystems IRIS is a great data platform and it is met the current features required by the market. In this article, you see the top 10:

Note: this list was updated because many features are added to IRIS in last 3 years (thanks @Kristina Lauer)

Hi guys,

Would like to replace our scheduled Tasks to instead run in a production, so basically the same code running in OnTask () to be instead called in a Business Service (I guess) and use the Interval filed to specify the iteration, so with adapter would be suitable in this case, and I noticed the Schedule filed as well but not sure how to use it? 

Thanks

Hi - I'm refreshing my IRIS instance, now upgraded to 2025.1, and ensuring IPM is installed in each namespace, as well as git-source-control, but in my first attempt I get this error. 

Everything else seems to work - but why the error (I'd like to get rid of it) ?

Hi all,

I can't find the list of business host setting sections and (crucially) how to refer to them in the SETTINGS parameter, as marked in purple here:

Does anyone know where this list lives?

For my hundredth article on the Developer Community, I wanted to present something practical, so here's a comprehensive implementation of the GPG Interoperability Adapter for InterSystems IRIS.

Every so often, I would encounter a request for some GPG support, so I had several code samples written for a while, and I thought to combine all of them and add missing GPG functionality for a fairly complete coverage. That said, this Business Operation primarily covers data actions, skipping management actions such as key generation, export, and retrieval as they are usually one-off and performed manually anyways. However, this implementation does support key imports for obvious reasons. Well, let's get into it.

InterSystems IRIS 2025.2.0 introduces several features to improve the user experience of configuring OAuth2.

- OAuth2 is now a native authentication type and can be easily enabled for your services and web applications. Previously, OAuth2 was a type of delegated authentication.

- You can now create resource servers with the new OAuth2.ResourceServer class, which simplifies resource server configuration significantly. Previously, resource servers were instances of OAuth2.Client.

- The OAuth2.ResourceServer class and provides a sample authenticator for determining user permissions which, for

I have written a new script for csv file export, which writes lines to a %Library.File file based on a SQL query.

The code is simplified into the following as 

try {
    // set up file as %Libary.Fileset f = ##class(%Library.File).%New()
    set f.Name = "export.csv"if (##class(%File).Exists(f.Name)) { $$$ThrowOnError(##class(%File).Delete(f.Name)) }
    $$$ThrowOnError(f.Open("WUN"))
    $$$ThrowOnError(f.LineTerminatorSet($C(13,10)))
    
    // Write lines from SQL 
    &sql(DECLARE cur CURSORFORSELECT a, b into :a, :b	FROMtable)
    &sql(OPEN cur)
    &sql(FETCH cur)

Say I have an ObjectScript object called Book. It has 2 properties title and author. It extends JSON.%Adaptor, so I can call book.%JSONExport() and get this output:

In my web service I want to have a search function that returns an array of Books along with the total number of responses, like this:

An experiment on how to use the LangChain framework, IRIS Vector Search, and LLMs to generate IRIS-compatible SQL from user prompts.

This article was based in this notebook. You can run it with a ready to use environment with this application in OpenExchange.

Setup

First, we need to install the necessary libraries:

!pip install --upgrade --quiet langchain langchain-openai langchain-iris pandas

Next, we import the required modules and set up the environment:

import os
import datetime
import hashlib
from copy import deepcopy
from sqlalchemy import create_engine
import getpass
import pandas as pd

If you look at the values.yaml of the IKO's Helm chart you'll find:

useIrisFsGroup:false

Let's break down what it is and in what situations you may want to set it to true.

FsGroup refers to the file system group.

By default, Kubernetes volumes are owned by root, but we need IRIS to own its files (IRIS in containers is installed under irisowner user). To get around this we employ one of two methods:

1) initContainers

The initContainers run before app containers (like IRIS) in a pod.They generally set up the environment for the application and then run to completion/terminate.

There is a list of numbers from 1 to 190.

AllList="1,2,3,4,5,6,7,8,9,.....,187,188,189,190"

There is a collection of sets of these values:

List(1)="3,5,6,7,9"
List(2)="1,2,6,9"
List(3)="5,8,9"
List(4)="2,4,6,8"
List(5)="4,7,9"

What is an elegant approach in Object Script to pick the least number of list items:

• List(1)
• List(5)
• List(n)

That together would cover as many numbers as possible from the AllList.

Interested in best coverage over efficiency.
