⏯️ The Ultimate 3D Industrial Simulation powered by a Game Engine with InterSystems IRIS

In this demo, InterSystems IRIS Interoperability comes alive in an amazing, game-like user experience based on our Ultimate Control Tower demo. We visualize machines in a virtual 3D factory building, interacting with InterSystems IRIS in real time—displaying current statuses and sensor data, simulating machine outages and predictive maintenance scenarios, and triggering workflow tasks and actions in InterSystems IRIS. By using a mobile app on a tablet—and even a VR headset for a fully immersive experience—we unleash the power of InterSystems IRIS.

Vector Search Performance

Test Objectives

InterSystems has been testing Vector Search since it was announced as an “experimental feature” in IRIS 2024.1. The first test cycle was aimed at identifying algorithmic inefficiencies and performance constraints during the Development/QD cycle. The next test cycle used simple vector searches for single threaded performance analysis to model reliable, scalable and performant behaviour at production database scale in IRIS, and performed a series of comparative tests of key IRIS vector search features against PostgreSQL/pgvector. The current test cycle models the expected behaviour of real-world customer deployments using complex queries that span multiple indices (vector and non-vector) and run in up to 1000 concurrent threads. These tests will be run against IRIS, PostgreSQL/pgvector, and ElasticSearch

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

Dear InterSystems-Maintainer Team,


I am currently conducting a comparative evaluation of FHIR clients as part of my
bachelor thesis in health informatics. One of my evaluation criteria is the response
time to support inquiries.


Therefore, I would like to kindly ask the following question as part of my analysis:
How can I read and write custom FHIR extensions using your client library?


If available, could you point me to any documentation or examples?


Many thanks for your time and support!

⏯️ Closing the Scientific Knowledge Gap with AI

For venture capitalists (VCs), evaluating research can be challenging. While researchers typically possess years of training and deep expertise in their field, the VCs tasked with assessing their work often lack domain-specific knowledge. This can lead to incomplete understanding of scientific data and an inability to direct organizational initiatives. To solve this problem, we have designed a solution that empowers VCs with AI-driven due diligence: ResearchExplorer. ResearchExplorer is powered by InterSystems IRIS and GPT-4o to help analyze private biomedical research alongside public sources like PubMed using Retrieval-Augmented Generation (RAG). Users submit natural language queries, and the system returns structured insights, head-to-head research comparisons, and AI-generated summaries. This allows users to bridge expertise gaps while securely protecting proprietary data.

Hi,

I have a mirrored database called ROUTER.

I have a primary server T1 and a "Disaster Recovery" server T2.

When I activate ROUTER database on T2, I get the error it says the "Database could not be mounted".

I went to the audit database and it shows "Attempt to access a protected database".

T2 in mirror monintor shows "Connected" "Caught up" "Warning! Some databases need attention"

T2 show the ROUTER database as being "Mounted/R"

Both T1 & T2 are Linux servers. The ROUTER database file IRIS.DAT have the same Linux permissions

Metabase IRIS Driver

Hi InterSystems Community! I'm Sidd one of the interns at the Singapore office and I recently had the chance to develop to develop a driver to connect IRIS to Metabase to help some of the Sales Engineers here. I was encouraged to share it here so that if any others have a similar issue they can use the driver and as well as get some feedback on potential improvements. The full GitHub repo with the quick start step, brief overview and the driver building process can be found here.

In the modern world, the most valuable asset for companies is their data. Everything from business processes and applications to transactions is based on data which defines the success of the organization's operations, analysis, and decisions. In this scenario, the data structures need to be ready for frequent changes, yet in a managed and governed way. Otherwise, we will inevitably lose money, time, and quality of corporate solutions.

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

InterSystems IRIS 2025.2 introduces the IRISSECURITY database, the new home for security data. Unlike IRISSYS, the previous home for security data, IRISSECURITY can be encrypted, which secures your sensitive data at rest. In a future version, IRISSECURITY will be mirrorable.

This version also introduces the %SecurityAdministrator role for general security administration tasks.

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?
