InterSystems worked closely with the Red Hat Insights team to implement a curated set of recommendations for system administrators to ensure the best experience running InterSystems IRIS on Red Hat Enterprise Linux (RHEL). Included with all RHEL subscriptions, the Insights service proactively identifies potential issues with monitored platforms and applications running on RHEL. Through our joint collaboration, Insights now watches for common scenarios that decrease the performance of IRIS in most cases and offers an InterSystems-approved recommendation for consideration.

It's been a while (and everyone is well-rested after Advent Of Code!) so let's run another round of Code Golf.

Your task is navigating in a grid-like labyrinth in a clockwise spiral pattern. As it traverses the matrix, it collects characters, revealing a secret message. Your challenge: find the shortest, most elegant code to decode this spiral cipher.

Hello!

This article is a small overview of a tool that helps to understand classes and their structure inside the InterSystems products: from IRIS to Caché, Ensemble, HealthShare.

In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Studio and examine the code there.

If you are learning InterSystems products, reviewing projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of ObjectScript Class Explorer!

Hi Community,

This is a detailed, candid walkthrough of the IRIS AI Studio platform. I speak out loud on my thoughts while trying different examples, some of which fail to deliver expected results -  which I believe is a need for such a platform to explore different models, configurations and limitations. This will be helpful if you're interested in how to build 'Chat with PDF' or data recommendation systems using IRIS DB and LLM models.

So the title says it all:
What causes a broker RESPONSE to have Transfer-Encoding:chunked?
sometimes the response seems to not have the "Transfer-Encoding:chunked" but sometimes it does, what may casue this behaviour?

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.

Hello all,

We are currently developing a set of cubes in Unified Care Report (UCR) for data analysis purposes. However, we are encountering issues with cube dependencies, where certain cubes rely on others to be compiled beforehand. The complexity of these dependencies is becoming increasingly difficult to manage, particularly when attempting to deploy the cubes.

The problem arises when trying to compile a cube that depends on another cube, which may also have its own dependencies. For instance, when compiling the Test.Cube.

I am using an Apache webserver on RH8, which is working fine. However, I get the following message:

Directory /opt/webgateway/conf/temp/ does not exist or has incorrect permissions. This will limit the Web Gateway's functionality.

The folder is indeed missing, but in what way is it limiting functionality?

Hello! 
So my question is quite simple, Do the different data models of Intersystems all support the ACID properties?
I assume that for the SQL data model implementation it does, But does it also work for global (i.e the hierarchical  data model)?
I searched the docs and the different articles, It seems for example that here its implied that the different data models of Intersystems  DO indeed support the ACID properties and allow for safe insertion, deletion etc... in concurrent operations to the server that is.

Would love to get a clarification, Thx!

REST API with Swagger in InterSystems IRIS

Hello

The HTTP protocol allows you to obtain resources, such as HTML documents. It is the basis of any data exchange on the Web and a client-server protocol, meaning that requests are initiated by the recipient, usually a Web browser.

REST APIs take advantage of this protocol to exchange messages between client and server. This makes REST APIs fast, lightweight, and flexible. REST APIs use the HTTP verbs GET, POST, PUT, DELETE, and others to indicate the actions they want to perform.

Hi Community,

Hey guys!

I'm working on a Java application that connects to Iris via JDBC.
I need to disable SharedMemory via connection URL.
I would like to know how I can check if the parameter was turned on or off within Iris when connecting to Java.
Thanks for your help!

⏯ FHIR Repository and FHIR SQL Builder @ Global Summit 2024

For example we have a docker app that receives a .csv file from windows environment and then do some processing on it in docker linux environment.

Windows encode new line in CRLF format, but linux can understand only LF and throw an unexpected errors like
 

ERROR #7207: Datatype value '100 ' is not a valid number > ERROR #5802: Datatype validation failed on property 'esh.i14y.csv.CelciusCSV.Record:Temperature', with value equal to "100 "

Is there a way to convert new line logic inside iris container in cases when .csv file (and other possible files) comes from windows environment ?

For some build scripting with the InterSystems Package Manager, I'd like to first uninstall a package with `zpm "uninstall"` and then load it from disk using `zpm "load"`. That way anything that got deleted from the source will also be deleted from IRIS. 

The problem is that `zpm "uninstall"` takes in a module name and I only have the directory path to the package source. Is there a way to get the module name for an installed IPM module given the source path? It's okay  to assume that it has previously been installed from that same directory with `zpm "load"`.

I have an Iris Intersystems instance that works with Apache server  on Windows 11 machine. Are there any clear and simple instruction or documentation  that explain how to migrate from Apache server to Nginx server?

Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Minimum working example

Hi all! Here I would like to share how we use vector search and GenAI with InterSystems technology. As an example, I'll describe BG-AppealAI project, which our company submitted to the InterSystems Vector Search, GenAI and ML Contest. BG-AppealAI application can write an appeal if you upload an insurance contract and the insurance company’s letter with a refusal to pay medical expenses. Of course, we are aware that at the moment AI has not reached such a level as to create ready-made legal documents.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)

In this post, I show strategies for backing up InterSystems IRIS using External Backup with examples of integrating with snapshot-based solutions. Most solutions I see today are deployed on Linux on VMware, so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Hello All,

Using Flask, REST API, and IAM with InterSystems IRIS

Part 3 – IAM

InterSystems API Manager (IAM) is a component that allows you to monitor, control, and manage traffic from HTTP-based APIs. It also acts as an API gateway between InterSystems IRIS applications and servers.

Using Flask, REST API, and IAM with InterSystems IRIS

Part 2 – Flask App

Flask is a web development microframework written in Python. It is known for being simple, flexible, and enabling rapid application development.

Installing Flask is very simple. Once you have python installed correctly on your operating system, we need to install the flask library with the pip command. For REST API consumption, it is advisable to use the requests library. The following link provides a guide to installing flask: https://flask.palletsprojects.com/en/stable/installation/

Is it possible to change the WebGateway Port i.e. from i.e. 57773 to 443 to use it as:

Meaning: https://myserver:443/iris/csp/sys/%25CSP.Portal.Home.zen

Are there any known problems or other suggestions?
