Has anyone done this successfully?  Customer wants to receive HL7 data over https using OAUTH 2.0 client credentials.  I am assuming a custom Operation will be needed?  I tried using CoPilot for assistance but was unsuccessful.  I am not great with Object script :( 

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

• %-variables (process variables). Reusing only in the same process
• Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

• Using Interoperability Production.

During my work with customers and also following I often met the 
explicit or embedded question: What is this "GLOBALS" ?
I'll try to explain the history to unfold the context.

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh

⏯️ HL7 Validation Error Profiler: Rapid Insights into Batch HL7 Data Quality Issues

This demo highlights how HL7 validation logs can be transformed into scalable, actionable data quality insights using a lightweight application built on top of Health Connect.

• Batch ingestion and parsing of HL7 validation error logs into structured data
• Aggregation of errors by segment, field, and type to reveal systemic issues
• Interactive dashboard (Streamlit) for filtering, exploration, and root cause analysis
• Rapid identification of top error patterns across entire data feeds
• Natural language chatbot for intent-driven data investigation and querying
• PDF report generation for sharing clear, evidence-based feedback during data source onboarding 

Special thanks to @Henry Wojnicki for his contributions to designing and refining the application workflow.

Hi, Community!

Here's another way AI can speed up your processes—take a look! 👇

Generating Transformation Descriptions with the DTL Explainer

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).

Every great community is enriched by those who work tirelessly behind the scenes, crafting the knowledge and resources that help others grow. In the InterSystems Developer Community, one such person is @Derek Robinson — a dedicated educator, whose passion for teaching has helped shape how developers everywhere learn to work with InterSystems technologies.

👏 Let's take a closer look at Derek's journey in the InterSystems ecosystem.

Hi Community!

Introduction
InterSystems IRIS Adaptive Analytics is an optional extension that provides a business-oriented, virtual data model layer between InterSystems IRIS and popular Business Intelligence (BI) and Artificial Intelligence (AI) client tools. Adaptive Analytics is powered by AtScale, the AtScale documentation can be found at this link: https://documentation.intersystems.atscale.com

This article will showcase some AtScale features that can facilitate data analysis:

1. Cube creation
2. Excel visualization
3. Parallel Period
4. Queries
5. Snowflake
6. Security

7. Aggregates

The 2025.1.4 and 2024.1.6 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: 

• April 15, 2026 – Alert: Removal of InterSystems IRIS for Health and Health Connect 2024.1.4 and 2024.1.

I'm starting to play more with AI enabled coding. 
I've been using Github Copilot inside Visual studio code, which is very good at coming up with autocomplete suggestions that are accurate and useful. (Along with some utter rubbish, naturally).
For web development I'm starting to use Claude Code in VS Code to help create web sites and integrations. I want to see how it can help with IRIS development. 

However I can't get claude to read any iris code directly as I'm connected to my server via isfs server connections.

Summary

Issue

• The impacted versions of InterSystems IRIS for Health and Health Connect are being removed from WRC distribution sites due to issues identified in several FHIR and healthcare interoperability features.
