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?

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?

InterSystems Kubernetes Operator (IKO) 3.9 is now Generally Available.  IKO 3.9 adds new functionality along with numerous bug fixes and security updates.  Highlights include:

• podTemplate initContainers can now specify volumeMounts
• computeAffinity allows compute nodes to move to the zone of your primary data node

Follow the Installation Guide for guidance on how to download, install, and get started with IKO.  The complete IKO 3.9 documentation gives you more information about IKO and using it with InterSystems IRIS and InterSystems IRIS for Health.

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.

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.

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.

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.

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.

What tools or techniques do you use to debug a Production during development? I know the Management Portal shows the message queue and event log, but I'm wondering if there are better ways to trace a message through the full BS > BP > BO flow without relying only on logs.

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?

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.

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.

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!

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?

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.

Hi community.

How do i count distinct values over cumulative date dimension?

I got calculated measure function defined in cube: COUNT([dimension].[H1].[dimension].Members, EXCLUDEEMPTY)

[dimension].[H1].[dimension] = non-unique numerical fields of ids

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:

ERROR #5001: No member provider object found for member function: MEMBER(5)

All syntax is correct. I checked it twice.

Hey Community,

We're pleased to invite everyone to the upcoming Kick-off Webinar for InterSystems Programming Contest: AI Agents for FHIR!

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
