Question Sergey Pavlov · Aug 25, 2017

Is there a way to omit or skip rollback of some data changes during a transaction rollback?

Is there a way to omit or skip rollback of some data changes during a transaction rollback? Maybe some sort of "autonomous transaction"?

The issue is with error logging in transaction. For example we may have in nested calls the following structure:
TS
<some code>
<error happens>
TRO 1
<error log to database>
but if this code is in another transaction, and that rolls back we lose error data.

Is there a way to do something like
TS
<some code>
<error happens>
TRO 1

<autonomous transaction start\flag>
<error log to database>

so error log will be stored anyway?

Claude Code vs ISFS. Has anyone cracked how to get one to see the other?

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.

Scripting with .Net core 10 and Iris SDK

One of the newest features of .Net core 10 with C# 14 is the file-based apps. This feature allows you to execute C# code in a simple .cs file without the need to create a solution, a project, or any of the related structure.

For example you can create a script.cs file using the notepad with the content: 

Console.WriteLine(“This is a script in c#.”);

Then in the command line or the terminal you execute the command:

dotnet run script.cs

There is plenty of information about this new feature of .net 10.

[Demo Video] HL7 Validation Error Profiler: Rapid Insights into Batch HL7 Data Quality Issues

#North American Demo Showcase entry

⏯️ 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.

Teaching an AI Coding Agent to Work Safely with a Legacy InterSystems Caché Application

We didn't start with a big AI strategy.

We had a legacy InterSystems Caché 2018 application, a lot of old business logic, and a practical need: build a new UI and improve code that had been running for years. At first, I thought an AI coding agent would help only with a small part of the work. Maybe some boilerplate, some REST work around the system, and a bit of help reading old ObjectScript.

In practice, it became much more than that.

Supply Chain - Supply Chain Orchestrator (SCO)

Before finding the best solution for Supply Chain, we need to understand what Supply Chain is. Well, regardless of the language used, the term is known by the name already mentioned. For your information, the translation in Brazilian Portuguese is "Cadeia de Suprimentos" (Supply Chain), sometimes also called "Cadeia Logística" (Logistics Chain), but we will not dwell on the nomenclature, but rather on the meaning.

How I usually learn InterSystems IRIS (resources + notes)

Hi, every one. Again, it's me!!😀😀

Recently I was trying to organize some learning materials for InterSystems IRIS😆, and realized that the resources are actually quite scattered.🤐

So I put together a list here—grouped by categories—for anyone who:

  • is new to InterSystems
  • or wants to go deeper into specific areas

Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).

Practical ObjectScript Coding: From JSON to Globals to SQL

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

Prevent specific table data from being rolled back

InterSystems FAQ rubric

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.

Temporary Globals and the IRISTEMP Database

By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

How to use JobServer properly to have a certains amount of IRIS processes available amongs multiple Apache nodes ?

I use cspa24.so Apache module to connect to IRIS. I have notified that idle Apache processes will always result in connections being kept open to the IRIS server, and thus some amount of IRIS processes being kept alive (and dedicated to those apache processes) because of those connections.

Eg: if I have 50 idle Apache processes, I will have 50 IRIS processes being kept alive in IRIS even if there is no client connection being made at that time. 

It's even worse with multiple Apache nodes and a load balancer.

How to Download and Install InterSystems IRIS

Updated 14/04/26

Before you can start building with InterSystems IRIS, you need a working local or server installation. This guide walks through downloading the distribution and installing IRIS on Windows in a straightforward way, focusing on the steps and decisions that matter in a development setup.

I’ll cover where to get the appropriate version, what prerequisites to check before installing, and how to run through the installer on your platform. The goal is to get you to a clean, usable environment with minimal friction, so you can move on to writing code, exploring the data platform, and integrating with your existing tools.

To download a Community version, please read this article: How to get InterSystems IRIS Community Edition. It explains the different ways to obtain InterSystems IRIS Community Edition, highlighting options for local, containerized, and cloud-based setups. It shows how to use Docker to quickly pull and run a ready-to-use IRIS instance. You can also learn how to deploy IRIS in the cloud via marketplaces like AWS to avoid local installation. What's important here, this guide walks through downloading an install kit from the InterSystems Evaluation Service and selecting the right version and platform.

Convert Python %SYS.Python List to %Library.DynamicArray in Objectscript

As part of a recent documentation technical project to optimize the search, I needed to use Embedded Python in my ObjectScript code. The main blocker was passing a Python list from a Python class method to a ObjectScript method. Sending the list by reference to the python method, populating it with the Insert() method, and returning the reference to the ObjectScript method resulted in an list with type %SYS.Python, a process that was straightforward but not efficient.
I explored an alternative method: converting a Python list to an ObjectScript list using JSON as the intermediary format.

Code not always updated in Mirror?

This past weekend we ran into something odd. When we failed over our mirror from 2022.1.3 to 2025.1.3 the one of the Business Rules that was on what became the Primary (2025.1.3), had a rule within it that was removed back in January. When the Failover occurred, we had to scramble to backup, disable, and remove the Rule that shouldn't have been there. 

Both the Data and Code live within the same IRIS.dat that is the main MIRROR database for that Namespace. 

If this happened to one Class file, could it happen to others we do not know about?
