In my previous article introducing gj :: configExplorer I flagged up how an apparent bug in the Windows elements of the Native API for Node.js means it's not currently available to run in VS Code on a Windows desktop. In a comment on that article I offered a workaround, but this requires a Docker-equipped Linux host you can SSH to.

If you don't have a suitable target it's now possible to leverage your local Windows Docker Desktop. Here's how:

1. Open a new VS Code window.

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

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:

How do you assign a property in a RUL (not a DTL or BPL) from a function value?  I've tried with the package/classname, without, with .., without and even looked all the way down to the parser but still can't see how.  There is no examples and the documentation doesn't help

So this works

<assign property="RuleActionUserData" value="&quot;A01&quot;"></assign>
 

This doesn't complile

<assign property="RuleActionUserData" value="##class(SomePackage.SomeClass).EventTypeToHL7Type(Document)"></assign>

SomePackage.SomeClass extends EnsRules and the method is a classmethod and final

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.

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.

Kong Traditional Mode

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
}

I get the error:

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.

It seems to me that for some reason this didn't make its way to the official documentation
and seems to be rather unknown though implemented already in IRIS 2020.1

Thanks to @Dan Pasco I got a hint on the classes involved.
I used the recommended sequence of how to use it. 
it is all directly taken from Class Reference and I just collected it to create a first overview.

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
irispy.set("myGlobal", "hello world!") 

To establish a connection, you must either hard-code connection information in your script or you must prompt the user for the information.

To help manage these IRIS connections in my own projects, I created irisconns on Open Exchange.

irisconns allows you to decouple your connection information from your project/code by allowing you to save that connection information into files that are separate from your code. (Think "DSN" and "ODBC" for your IRIS Native SDK connections.)

Getting Started

To get started with irisconns, create either an irisconns or .irisconns file in your project's working directory, any parent directory to your working directory, or your home directory. Populate your irisconns file with connection information in an INI file format:

# 'default' is the connection returned if no name is provided.
[default]
hostname = localhost
port = 1972
namespace = USER
username = _SYSTEM
# confirm password? true or false?
confirm = false

# This connection name is "TEST".
[TEST]
hostname = test-server
port = 1972
namespace = USER
username = _SYSTEM
# confirm password? true or false?
confirm = false

# This connection name is "PROD".
[PROD]
hostname = prod-server
port = 1972
namespace = %SYS
username = _SYSTEM
# confirm password? true or false?
confirm = false

You will also need to copy the associated irisconns.py or irisconns.js libraries into your project so that you can import the irisconns module from your code. (Currently, only Python and Node.js libraries exist.) You also need to install the IRIS native packages for your programming language:

# Install Dependencies for Python
cp /path/to/irisconns/irisconns.py ./irisconns.py
pip install intersystems-irispython

# Install Dependencies for Node.js
cp /path/to/irisconns/irisconns.js ./irisconns.js
npm install @intersystems/intersystems-iris-native

Using "irisconns"

Once installed, you should be able to use/prompt for your connection configuration:

# Python Connection Example
import irisconns

# default connection
irispy = irisconns.get_irispy()

# named connection
irispy = irisconns.get_irispy('TEST')

# usage
irispy.set('hello world!', 'test', 1)

// Javascript Connection Example

// Import the package
const irisconns = require('./irisconns.js');

// Wrap in an async function so we can await the connection...
(async () => {
  // 'default' connection
  const iris = await irisconns.get_iris();

  // named (i.e. "PROD") connection
  // const iris = await irisconns.get_iris('PROD');

  // usage
  iris.set('hello world!','test',1);
})()

The above code will produce prompts, similar to the following:

# Connecting to default
Hostname    : localhost (default)
Port        : 11972
Namespace   : USER (default)
Username    : _SYSTEM
Password    : [hidden]
Confirm     : [hidden]

Closing

You can find more information about irisconns on the Open Exchange page. Hopefully you will find it useful!

Thanks!

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.

Hi,

I do have the problem to send mails to outlook after getting the new OAUTH2 token. 

 I have no problem getting the token, but after I got the token I try to send the mail thru smtp but authorization failed , please see my try to send the token thru the %Net.Authenticator mechanism %Net.SASL.XOAUTH2

Is this ok?

Or is there an other method to authenticate using the needed bearer method instead of user/pwd with the authenticator? 

 ....code to get the token is working..

Hi Guys,

I'm looking to setup an MQTT adapter that also acts as broker to connect directly to an MQTT clients, is there an IRIS adapter or client that can be used as Broker as well?

Thanks

Hi,

%SYS.LDAP - InterSystems IRIS Data Platform 2025.2 - including private class members   states that
 

"abstract class %SYS.LDAP

Requires %syLDAP.INC to be included in your COS routine for some macro definitions."

How can I include %syLDAP.INC for the compilation of my code which uses %SYS.LDAP ?   I need the definitions for the $$$LADPxxxx macros (such as $$$LDAPSUCCESS).

Thank you.

Hi,

I am trying to include in my Data Transform, if OBX 5.1 (Observation Value) Contains certain text i.e. DETECTED then populate the Abnormal Flag field with a certain letter.

Sometimes the text can be uppercase, lowercase or a multiple of both.

Any help would be much appreciated.

Thanks

Jason

Hi,

Does calling the BIND method of %SYS.LDAP, with the username, domain and password of the user that  needs to be authenticated- the right way to authenticate him/her ?

Also - am I correct in assuming that something like this is independant to (and I don't  need to specify setting for),  System Security -> LDAP Options 

Thanks

Steve
