How to properly handle long-running processes in a Business Process without blocking the Production?

I have a Business Process that needs to call an external API that may take several seconds to respond. I'm worried that keeping the BP blocked waiting for the response could affect the overall Production throughput. Is there a recommended pattern for handling async calls inside a BPL or custom BP class to avoid this kind of bottleneck?

A Fresh Start - What would you do differently a second time round?

Hey everyone.

My team and I have a rare opportunity to start from scratch, and I am keen to know what things others that have gone through a similar process did differently. Obviously there's the immediate benefit of losing any technical debt that has built up over 10+ years of an ever changing environment along with many organisational changes and merges, but I'm thinking about the things that we can do to make life a lot easier for the next 10+ years.

I'm approaching the need to send notifications through a Microsoft Exchange or Gmail servers. however my last foray into this, I was blocked due to an issue inside my SSL certificate is what I thought after the attempt.

So my attention will be on trying to match the cryptography in the SSL certificate I produce compared to the mail server I'm trying to use.

Has anyone else had an issue with this approach? My other option is Amazon SNS potentially. I do have a functional MS Teams channel for alerts, and can make different notification channels as well.

Any help or insights are appreciated.

What is the right approach to share common logic across multiple Business Operations?

I have several Business Operations that share similar behavior, like building HTTP headers or parsing a specific response format. In C# I would extract this into a service class or a base class. What is the recommended way to do this in IRIS? Should I use a utility class, a common superclass, or is there another pattern the community prefers?

Randomizing Unit Tests With %Populate

In our previous article, we explored the basics of unit testing in IRIS and the ways to apply it to a REST API. We even figured out how to test logic before finalizing network configurations and authentication, allowing us to focus solely on testing the API contents. Today, we will build upon that foundation and elevate our unit testing strategy by using another tool: %Populate .

At first glance, the %Populate class appears to be very simple. You can create a class that extends both %Persistent and %Populate and inherit a Populate method designed to generate randomized records.

Enhancing FHIR Data Exploration with Local LLMs: Integrating IRIS and Ollama

Introduction

In my previous article, I introduced the FHIR Data Explorer, a proof-of-concept application that connects InterSystems IRIS, Python, and Ollama to enable semantic search and visualization over healthcare data in FHIR format, a project currently participating in the InterSystems External Language Contest.

In this follow-up, we’ll see how I integrated Ollama for generating patient history summaries directly from structured FHIR data stored in IRIS, using lightweight local language models (LLMs) such as Llama 3.2:1B or Gemma 2:2B.

The goal was to build a completely local AI pipeline that can extract, format, and narrate patient histories while keeping data private and under full control.

All patient data used in this demo comes from FHIR bundles, which were parsed and loaded into IRIS via the IRIStool module. This approach makes it straightforward to query, transform, and vectorize healthcare data using familiar pandas operations in Python. If you’re curious about how I built this integration, check out my previous article Building a FHIR Vector Repository with InterSystems IRIS and Python through the IRIStool module.

Both IRIStool and FHIR Data Explorer are available on the InterSystems Open Exchange — and part of my contest submissions. If you find them useful, please consider voting for them!

Common Table Expressions (CTEs) in InterSystems IRIS SQL

Abstract

Common Table Expressions (CTEs) provide a structured framework for defining reusable intermediate result sets within SQL statements. InterSystems IRIS implements CTEs via the WITH clause, enabling clearer query composition and modular analytical processing while remaining fully integrated with the IRIS cost-based optimizer.

This article explores the semantics of CTEs in InterSystems IRIS, explains their interaction with query optimization, discusses appropriate deployment scenarios, and presents executable examples illustrating practical patterns for production environments.

#Embedded GIT initial setup question with IRIS for Health 2025.1.3

We have a long running InterSystems Engine with an Interface Development Team.  We have implemented basic interface and code development processes using mostly manually created helper tasks and functions.
We are looking to upgrade these processes by installing and starting to use Embedded GIT in our DEV spaces first.  We will not use it to deploy changes to PRODUCTION at first, keeping our same current process that the team is very comfortable with.  
We plan to start by using the BASIC mode in GIT, to avoid confusion over multiple branches and other version control functions.

Web Gateway access with Kerberos

Hello,

Looking for some additional help, maybe someone who has experience with this before, in setting up and configuring the Web Gateway with Kerberos.

Have read through the documentation (at the link below) and it's a good start but seems there are some details missing, or I'm not clear on. 

Questions: 

  • Is there a external enterprise Kerberos server required, or is this set up contained within the local server?
  • Is there a step-by-step instructions on what to do and configure to successfully complete this?
  • Are there there config changes necessary for Apache?

How to refresh user credentials used by the VSCode InterSystems Server Manager Extension?

Hello everyone, I am working with the VSCode extension by connecting to clients' IRIS servers remotely with my personal user (pdileo). However, one of the development environments was recently updated and my user was created for the second time with a different password.

I noticed that the VSCode extension no longer allows me to log in because the password has been changed, without asking me for a new one, only showing the 401 AxiosError.

Similar in Meaning, Opposite in Logic? - A Practical Workflow to Complement Vector Search with LLMs

Vector search is a retrieval method that converts text, images, audio, and other data into numeric vectors using an AI model, and then searches for items that are semantically close. It enables “semantic similarity search” from free text, which is difficult with keyword search alone.

However, in real use, I encountered cases where results that are “close in meaning” but logically the opposite appeared near the top of the search results.

This is a serious issue in situations where affirmation vs. negation matters. If the system returns the wrong answer, the impact can be significant, so we cannot ignore this problem.

This article does not propose a new algorithm. I wrote it to share a practical way I found useful when semantic search fails due to negation.

ClassMethods Are Not Your Friends

There seems to be a generous use of ClassMethods in ObjectScript code generally. I hope my own experiences aren't representative, but I bet they are. Forgive me for giving away the ending of this article, but in short: don't use them. Unless you can make a pretty convincing case that you have to, just never use them.1

What is a ClassMethod? In an ObjectScript class, you can define methods in two different ways: in a Method, you must instantiate an instance of the class to call the method, and in a ClassMethod, you can call the method without instantiating the class. Of course, in a ClassMethod, you don't have access to any properties of the object (because there's no object), but you can access globals (they are global, after all) and Parameters (which are class constants).

GraphRAG Inside InterSystems IRIS: Hybrid Retrieval for Fraud Detection (and other complex problems)

TL;DR: This article demonstrates how to run GraphRAG-style hybrid retrieval—combining vector similarity, graph traversal, and full-text search—entirely within InterSystems IRIS using the iris-vector-graph package. We use a fraud detection scenario to show how graph patterns reveal what vector search alone would miss.

Why Fraud Detection Needs Graphs

Every year, businesses and consumers lose billions to fraud. In 2024 alone, consumers reported $12.5 billion lost—a 25% increase year over year. What makes modern fraud so difficult to detect is that fraudsters rarely work alone.

An Introduction to AI Hub, Part 2: Custom MCP Servers

Welcome back to a series of introductory articles on AI Hub, the new product feature currently in an early access program! (links: EAP Site for download, documentation)

In the last article, we covered how to create agents and agent tools directly in ObjectScript using the new %AI classes. However, sometimes, instead of creating a new agent, you just want to add some custom tools to an existing agent so you can ask your local claude code, codex, copilot or other agent of choice to query your data directly. This is where MCP Servers might come in.

What is the FHIR equivalent of %NOINDEX for bulk loading and rebuilding?

Hi Community,

In traditional InterSystems SQL, I can use the %NOINDEX keyword during a bulk INSERT to improve performance and then run BUILD INDEX %ALL afterward to populate the indices.

I am looking to implement a similar strategy for an InterSystems FHIR Server.

  1. Is there a way to import/save FHIR resources while skipping the search table extraction (the FHIR version of %NOINDEX)?
  2. Once the data is loaded, what is the correct programmatic way to "rebuild" the search tables?

Thank you!

Interoperability metrics persisting in /api/monitor after calling DisableSAMForNamespace

Hi Community,

Interoperability metrics were enabled for a production using ##class(Ens.Util.Statistics).EnableSAMForNamespace(). However, after running DisableSAMForNamespace() and DisableStatsForProduction(), the metrics continue to appear in the endpoint output.

Is there a way to completely stop these interoperability metrics from displaying in the API metrics stream? Is there an additional step or cache clear required?

Set network interface on client host to be used for Cache connections

I'm connecting to Intersystems Cache database using Intersystems JDBC Driver. There are several network interfaces on client host. I need to make all the Cache traffic to go through a particular interface. Is there a way to choose which network interface to use for Cache connection via JDBC Driver API or somehow via Java code? The approach to use ip route add is suitable but I'm looking for a Java-way like setLocalAddress() on some APIs or something.

Custom Application Metric

I made a custom application metric, imported it to the USER namespace and used:

set status = ##class(SYS.Monitor.SAM.Config).Add.ApplicationClass("historymonitor.errorSensor", "USER")

to add it. When I do 'w status' it returns 1 so it is added but I still can't see the custom metric in the api/monitor/metrics endpoint. Even though I added %DB_USER in the application roles for api/monitor.

Does anyone know where the problem might be that the metrics endpoint still doesn't show my metric?

Then i got AGGREGATION function defined in Analyzer (that stored in ^DeepSee.CalcMbrs):

AGGREGATE(%TIMERANGE(TimeDimension.hierarchy.level,TimeDimension.hierarchy.level.CurrentMember),Measures.Measure)

This return an error:

LOAD DATA from file erroring after upgrade to 2025.1

We have a task that runs objectscript code to load data into a linked external table.  After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message.  The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is.  The result is the same with and without the USING clause, so don't let that confuse you.

`iris-persistence`: a Python-first persistence layer for InterSystems IRIS

With Embedded Python and the Native API, it is becoming increasingly natural to write part of IRIS application logic in Python. But one question quickly comes up: how can you manipulate IRIS persistent objects from Python without losing the connection to the native object model, class dictionary, indexes, storage, and SQL projections?

 

iris-persistence explores that question. The project provides a Python object persistence layer for InterSystems IRIS, inspired by %Persistent
