I am regularly contacted by customers about memory sizing when they get alerts that free memory is below a threshold, or they observe that free memory has dropped suddenly. Is there a problem? Will their application stop working because it has run out of memory for running system and application processes? Nearly always, the answer is no, there is nothing to worry about. But that simple answer is usually not enough. What's going on?

The 2025.1.2 and 2024.1.5 maintenance releases of InterSystems IRIS^® data platform, InterSystems IRIS^® for Health^TM, and HealthShare^® Health Connect are now Generally Available (GA). These releases include the fixes for a number of recently issued alerts and advisories, including the following: 

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

If you are looking for high availability you could use:

a) Kong Traditional Mode: Multiple Node Clusters

b) Hybrid Mode

c) DB-less Mode

Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.

Kong Traditional Mode

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

Hi, I'm wondering what are the diferences between a method or classmethod with the language set at tsql and a querry writen in sql.
If anyone know if there is some difference and what they are, I would be glad to learn. 😊

I was wondering what best practice was for using macros in Embedded Python, i.e. iris.execute('$$$MACRO()') or something else. Does anyone have insight into this?

Hi everyone,

It's me again😁. As usual I would like to share something I study recently, and today, I would like to share about the document DB😁.

1st of all, let's go to the documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GDOCDB_intro
Well, I must say, this one is much better to follow than the others, which I read before. 😭 Finally😭😭

Ok, let's start walking through it together

Here we go😀, we start a terminal from VSCode to connect to our IRIS

We are going to created Document DB demo.docpatient

Hi Community,

We’re excited to introduce the AskMe assistant—try it out for yourself!

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

Intro

In the process of trying to get more familiar with Objectscript I decided to try to build a general priority queue since I wasn't able to find an implementation anywhere. My though process for implementing this followed this general path.

Binary Heap

My first though to try to make this work quickly was to implement a binary heap and my first attempt at this used a multidimensional to build it. This version was relatively efficient, worked for strings/numbers natively, and worked for objects be letting the user override the comparitor.

As of InterSystems IRIS® data platform version 2025.1, InterSystems is officially deprecating MultiValue and including it in the Deprecated and Discontinued Features list. While InterSystems will continue to support existing customers using MultiValue, it is not recommended for new applications.

What This Means for You:

February 19, 2025 – Alert: SQL Queries Returning Wrong Results

InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.

Hi Community,

We're pleased to invite you to the upcoming webinar in Hebrew:

👉 Hebrew Webinar: GenAI + RAG - Leveraging Intersystems IRIS as your Vector DB👈

📅 Date & time: February 26th, 3:00 PM IDT

All pods are assigned a Quality of Service (QoS). These are 3 levels of priority pods are assigned within a node.

The levels are as following:

1) Guaranteed: High Priority

2) Burstable: Medium Priority

3) BestEffort: Low Priority

It is a way of telling the kubelet what your priorities are on a certain node if resources need to be reclaimed. This great GIF below by Anvesh Muppeda explains it.

The latest extended maintenance releases of InterSystems IRIS, InterSystems IRIS for Health, and HealthShare Health Connect are now available.
