Hi Guys,

I've created Business service with MQTT Inbound Adapter and here is my settings, BTW I'm using an IP with port not sure if it must be a url?

and this is my class:

Class SX3.Production.MQTTService Extends Ens.BusinessService
{Parameter ADAPTER = "EnsLib.MQTT.Adapter.Inbound";Method OnProcessInput(pInput As %RegisteredObject, Output pOutput As %RegisteredObject) As %Status
{set tsc=$$$OK
   set ^messageContent = pInput.StringValue
   
   Quit tsc
}}
 

But I'm getting the below error, not sure what I'm doing wrong?

Thanks

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

• Does not support access mode "ReadWriteMany"
• Does not support being mounted on more than one pod at a time
• Does not support access across availability zones

However, some Kubernetes add-ons (both provider and

For historic reasons we've got a mix of ADT feeds coming out of our PAS (TrakCare) to a wide range of downstream systems. In particular, there are some that are direct from TrakCare to the downstream systems, and many more that pass through Ensemble as our integration engine.

This is complicating management of the integrations, and so we'd like everything to go through the integration engine. In other words move from the flow in the top of the diagram to the flow in the bottom of the diagram:

So we want to build a couple of pass-through interfaces in Ensemble that respond identically to the

When we need to integrate Caché/IRIS with other relational databases, one common question arises: “How do I set up the JDBC connection?”.
The official documentation doesn’t always provide a straightforward step-by-step guide, which can be frustrating, especially for beginners.

In this article, I’ll walk you through the entire process of configuring a JDBC connection with MySQL, from downloading the connector to linking tables in Caché/IRIS.

Note: JDBC connections in Caché/IRIS have some limitations, especially regarding caching and the use of ResultSet. In many cases, you may need to adapt

A step by step implementation path to a cross regional stretched IrisCluster with Mirroring using the Intersystems Kubernetes Operator (IKO), Google Cloud Platform, and Tailscale.

I am giving this distraction the code name "Compliment Sandwich" for a reason yet to be realized, but I'd rather the community go right for the jugular shooting holes in a solution that implements wireguard based connectivity for our workloads in general, as I would like to refine it as a fall project leading up to KubeCon in Atlanta and if I miss the mark, Ill get it done before Amsterdam. 

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

If you are looking for high availability you could use:

a) Kong Traditional Mode: Multiple Node Clusters

b) Hybrid Mode

c) DB-less Mode

Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.

Hi Community,
I’m trying to execute a directory query in InterSystems IRIS using %SQL.Statement, but encountering an unexpected error.

Details:
The following command confirms that the directory exists:

Set dirPath="\\MYNETWORK_DRIVE\DFS-Shared_Product\GXM"
Write ##class(%File).DirectoryExists(dirPath)

It returns 1, meaning the path is valid and accessible.

However, when I try to execute this SQL query:

Set File=##Class(%SQL.Statement).%New()
Set Status=File.%PrepareClassQuery("%File","FileSet")
Set Result=File.%Execute(dirPath)
If Result.%SQLCODE {
    Write Result.%Message
}

Since we reached two important milestones for Go developers working with InterSystems IRIS:

• The Wait Is Over: Welcome GoLang Support for InterSystems IRIS — where we unveiled the new go-irisnative driver, providing a native database/sql interface for Go.
• GORM Meets InterSystems IRIS: Introducing gorm-iris — where we showed how to integrate IRIS with GORM, one of the most popular Go ORM libraries.

Now it’s time to see everything working together.

To demonstrate how easily Go developers can adopt InterSystems IRIS, I took an existing production-grade open-source project — the RealWorld Example App — which showcases a full-stack Medium.com-style clone implemented with Go Fiber, GORM, and SQLite.

With just a few configuration tweaks, I swapped out SQLite for gorm-iris, keeping everything else unchanged. The result?
A fully functional Go + Fiber application powered by InterSystems IRIS — no code rewrites, no ORM gymnastics, just a different database backend.

You can find the complete working demo here: github.com/caretdev/golang-fiber-iris-realworld-example-app

Every thriving community has members whose energy, creativity, and commitment help shape it into something extraordinary. In the InterSystems Developer Community, one such member is @Henry Pereira — a developer, open-source contributor, contest winner, and true believer in the power of collaboration.

👏 Let’s take a closer look at Henry’s remarkable journey and his continuing legacy in the InterSystems ecosystem.

While working with external languages for IRIS (such as Python and Node.js), one of the first things you must accomplish is making a connection to an IRIS instance.

For instance, to make a connection in python (from https://pypi.org/project/intersystems-irispython/):

import iris

# Open a connection to the server
args = {
	'hostname':'127.0.0.1', 
	'port': 1972,
	'namespace':'USER', 
	'username':'username', 
	'password':'password'
}
conn = iris.connect(**args)

# Create an iris object
irispy = iris.createIRIS(conn)

# Create a global array in the USER namespace on the server

If you thought native Go support for IRIS was exciting, wait until you see what happens when GORM enters the mix.

Just recently, we welcomed native GoLang support for InterSystems IRIS with the release of go-irisnative. That was just the beginning. Now, we’re kicking things up a notch with the launch of gorm-iris — a GORM driver designed to bring the power of Object Relational Mapping (ORM) to your IRIS + Go stack.

Why GORM?

GORM is one of the most popular ORM libraries in the Go ecosystem. It makes it easy to interact with databases using Go structs instead of writing raw SQL. With features like auto migrations, associations, and query building, GORM simplifies backend development significantly.

So naturally, the next step after enabling Go to talk natively with IRIS was to make GORM work seamlessly with it. That’s exactly what gorm-iris does.

At the moment, we have 10 HealthShare instance servers (5 x mirrored pairs), where we implement an External Backup approach, using the freeze/thaw commands against whichever server of the pair is the backup mirror member, to complete a VM level backup. These backups are stored to a disk within our control, to purge as required. This approach allows us to deliver a zero downtime backup approach.

Our future backup solution will be storing immutable backups, with the main concern being that the 10 HealthShare instance servers are quite sizable and that our current approach of backing up the
