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.

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..

...   set s=##class(%Net.SMTP).%New()
    
    set m=##class(%Net.MailMessage).%New()

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,

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

I was really surprised that such a flexible integration platform with a rich toolset specifically for app connections has no out-of-the-box Enterprise Service Bus solution. Like Apache ServiceMix, Mule ESB, SAP PI/PO, etc, what’s the reason? What do you think? Has this pattern lost its relevance completely nowadays? And everybody moved to message brokers, maybe?

Why This Matters

Managing IAM can be tedious when done manually — especially when your APIs are already well-documented using OpenAPI (Swagger) specs. Wouldn't it be great if you could automatically generate Kong services and routes directly from your OpenAPI spec?

That's exactly what this ObjectScript method does: it reads an OpenAPI 2.0 spec stored in the XData block of your spec class and generates a decK-compatible YAML file that can be used to sync your IAM configuration.

This approach:

• Reduces manual configuration errors
• Keeps your gateway in sync with your API spec
• Speeds up deployment

InterSystems FAQ rubric

The ^%GCMP utility can be used to compare the contents of two globals.

For example, to compare ^test and ^test in the USER and SAMPLES namespaces, it would look like this:
*In the example below, 700 identical globals are created in the two namespaces, and the contents of one of them is changed to make it the detection target.

USER>kill^test
USER>for i=1:1:100 { forj=1:1:7 { set^test(i,j)="Test"_i } }
 
USER>zn"samples"// change namespace to SAMPLES
SAMPLES>kill^test
SAMPLES>for i=1:1:100 { forj=1:1:7 { set^test(i,j)="Test"_i } }
 
SAMPLES>set

Hi community,

A colleague gets ERROR #822: Access denied every time he tries to log in via Management portal. It is NOT the case of wrong credentials: I reset his password password to a temporary one so it would prompt him to create a new one upon first login. He did get the prompt, changed his password and his next attempt at logging in displayed the same error.

The audit log record displays this:

I am truly excited to continue my "InterSystems for Dummies" series of articles, and today, we want to tell you everything about one of the most powerful features we have for interoperability.

Hey, even if you have already had a go, we plan to take a really close look at how to get the most out of them and make our production even better.

I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.

Has anyone here implemented such an integration successfully?

For example:

• Would it make sense to leverage IRIS’s Business Service + REST API adapter to connect to Google’s Pub/Sub REST endpoints?
• Or perhaps use an intermediate

I want to integrate Google Cloud Pub/Sub with InterSystems IRIS(HealthShare) and I see that InterSystems does not provide any out of the box Inbound/Outbound adapters for this integration though it has adapters for Kafka and other similar services. Any suggestions would be really appreciated.

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

✨ Why try it?

InterSystems IRIS Data Platform is a comprehensive, multi-model, multi-workload data platform that is ideal for accommodating the challenging requirements of applications for the Internet of Things. It is a complete platform for developing, executing, and maintaining IoT applications in a single, consistent, unified environment. It features a distributed architecture to support massive data-ingest rates and data volumes, while providing the flexibility and durability of an enterprise-grade transactional multi-model database to ingest, process, and persist data from a wide range of devices in different formats. It features a complete set of integration, event-processing, and integrated analytics capabilities, including full SQL support and text processing, business process orchestration, and a standards-based development environment.

Connect to, ingest, and persist a wide range of disparate device data types and formats

The data types associated with IoT applications are often heterogeneous, as they may originate from various devices with diverse functions and manufactured by different vendors. The underlying data platform must be able to ingest and process a wide range of raw data types in their original formats. Many applications also require the data platform to persist all of the disparate source data to detect deviations from normal ranges, accommodate downstream ad hoc analytics, maintain regulatory compliance, and fulfill other purposes.

The default request class, Ens.Request is fine for our initial workflow.  

We want to define other workflows that will reuse the same BPL class.  These workflows would send messages inbound to the BPL as different request classes.

Is this possible or is it required that we send in a request class matching the context request class in the context tab?

Thank you

One of the most common kinds of integration we are asked to do is emailing. One of the most typical email services our customers use is Microsoft’s Office 365. After setting up the right configuration on the Microsoft side, we can email from IRIS with two HTTP requests. By the end of this article, we will be able to send an email with an attachment through our Microsoft 365 service!

Microsoft’s REST API, called Graph, allows you to do a lot of things within Microsoft’s various apps, and it is precisely what we will employ to send our email.

Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

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

Building a Sensor Data Demo with Spring Boot and InterSystems IRIS

In the era of IoT and connected devices, sensor data is everywhere—tracking temperature in logistics, monitoring equipment performance, or recording environmental conditions. But capturing, storing, and analyzing this data in real time requires more than just hardware sensors.

It’s a practical example that combines Spring Boot, InterSystems IRIS, and a simple sensor simulation script to show how sensor data can flow from generation to storage and alerting.
Basically, the idea of ​​this project is to show all the integration

Finishing my previous example for multiple IRIS instances, I tried
to compose a local single instance version.  The step from the external
Python app to a version using embedded Python seemed to be obvious.
This was a wrong assumption, as some Python libraries just refused installation
into my local Windows-based environment.
