Audience

Those curious in exploring new GenerativeAI usecases.

Shares thoughts and rationale when training generative AI for pattern matching.

Challenge 1 - Simple but no simpler

A developer aspires to conceive an elegant solution to requirements.
Pattern matches ( like regular expressions ) can be solved for in many ways. Which one is the better code solution?
Can an AI postulate an elegant pattern match solution for a range of simple-to-complex data samples?

Consider the three string values:

• "AA"
• "BB"
• "CC"

The expression: "2 Alphabetic characters" matches all these values and other intuitively

You can check the free disk space at any time using the system utility class: SYS.Database and query: FreeSpace.

Here's how to try it in the IRIS terminal (go to the %SYS namespace and then run it):

zn"%SYS"set stmt=##class(%SQL.Statement).%New()
set st=stmt.%PrepareClassQuery("SYS.Database","FreeSpace")
set rset=stmt.%Execute()
do rset.%Display()

The output result example is as follows:

*In the command execution example, all databases are located on the same disk, so the free disk space (DiskFreeSpace) returns the same value.

Dumping result #1

Hello Community
I was running code in the terminal and attempted to interrupt its execution. During that process, I encountered an application error with a log entry dated 01/06/1841, the date seems unusual.

Error <INTERRUPT>ErrST+6^%ETN occurred within %ETN itself. Detailed information cannot be logged.

We have messages that are in a queued state for various reasons and when we do a manual shutdown of the instance, they are moved to a Suspended state. I thought I saw in the documentation somewhere a setting to make sure these messages stay in a queued state and not suspend them. Can someone confirm and point me in the correct location for that documentation, as I am trying to ensure that if we do have to manually shutdown a instance, someone doesn't have to remember to go back in and check for suspended messages and resubmit them?

Thanks

Modules what a topic! We don't have this notion in ObjectScript, but it's a fundamental concept in Python. Let's discover it together.

What is a Module?

I see modules as an intermediate layer between classes and packages. Let see it by example.

A bad example :

# MyClass.py
class MyClass:
    def my_method(self):
        print("Hello from MyClass!")

When you try to use this class in another script, you would do:

# class_usage.py
from MyClass import MyClass # weird, right?

my_instance = MyClass()
my_instance.my_method()

Why this is a bad example?

First because file names should be in snake_case accor

Hi,

I tried to create a client for Google Cloud Storage using a private endpoint.

like this:

S client=##class(%Net.Cloud.Storage.Client).%New()

S sc=client.CreateClient("",2,credentialsFile,"",.out,privateEndpoint)

But privateEndpoint seems not to be used when trying to send blob from a file:

D sc.UploadBlobFromFile(bucketname,blobname,filename)

We can see at the firewall that the client still tries to use the public endpoint for GCS.  

Even if the private endpoint is definitely reachable.

When we allow the public endpoint in the firewall then it is working as expected.

Is that a bug?

Users of the %UnitTest framework can now get test coverage information inside VS Code by combining the latest release (v2.0.0) of the InterSystems Testing Manager extension with @Timothy Leavitt's impressive Test Coverage Tool.

Above you can see the Test Coverage pane, which I have moved to the secondary sidebar on the right so it can more easily be explored in conjunction with the Test Explorer on the left.

Notice how the most recent test run (of all Test Coverage Tool's own unit tests) covered the BitValue method of TestCoverage.Procedures but not the BitCount method (nor 6 other methods).

InterSystems is pleased to announce the General Availability (GA) of the 2025.2 release of InterSystems IRIS® data platform. This is a Continuous Delivery (CD) release. Please note that the GA versions of InterSystems IRIS for Health™ and HealthShare® Health Connect™ 2025.2 are currently withheld due to mirroring limitations introduced by security updates (details below).

Release Highlights

This release introduces impactful enhancements across security, developer experience, operations, and interoperability. Notable new features include:

1.       Security Enhancements with the New IRISSECURITY

Working on wrapping an IRIS Cache ObjectScript method that runs for a few seconds. Trying to get UI updates to show BEFORE the method runs in an async/await function. But it seems to be running synchronously rather than asynchronously . So my question is does IRIS/ObjectScript CSP pages support futures with JavaScript or does it run all synchronously.

Are you familiar with SQL databases, but not familiar with IRIS?  Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar.  I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew.  However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better.  With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc.   I hope I can make things clearer and simpler for you and save you some time getting started.

Test Objectives

InterSystems has been testing Vector Search since it was announced as an “experimental feature” in IRIS 2024.1. The first test cycle was aimed at identifying algorithmic inefficiencies and performance constraints during the Development/QD cycle. The next test cycle used simple vector searches for single threaded performance analysis to model reliable, scalable and performant behaviour at production database scale in IRIS, and performed a series of comparative tests of key IRIS vector search features against PostgreSQL/pgvector. The current test cycle models the expected behaviour of real-world customer deployments using complex queries that span multiple indices (vector and non-vector) and run in up to 1000 concurrent threads. These tests will be run against IRIS, PostgreSQL/pgvector, and ElasticSearch

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

This part will now discuss and show in detail the steps needed to configure IAM to validate the access token present in the incoming request and forward the request to the backend if the validation

I am trying to catch an exception and write it to the Application Error Log, but cant find any details on how to do this in IRIS health.

Cant seem to find the %Logger class either.

This will be a short article about PEP 8, the Python style guide.

What is PEP 8?

In a nutshell, PEP 8 provides guidelines and best practices on how to write Python code.

• variable names should be in snake_case
• class names should be in CamelCase
• function names should be in snake_case
• constants should be in UPPER_CASE
• indentation should be 4 spaces (no tabs)
• private variables/functions should start with an underscore (_)
  • because in Python private variables and fonctions doesn't exist, it's just a convention
• your script should not run when imported
  • remember that when you import a script, the

I am trying to create users who only have `%SQL` Role for the INSTANCE. But I am unable to find any documentation on the `Security.Users` class.

See:

// Instantiate the Security.Users objectSet userObj = ##class(Security.Users).%New()// Set the username and passwordSet userObj.Name = userNameSet userObj.FullName = userFullNameSet userObj.Namespace = "USER"Set userObj.Roles = "%SQL"

Hi InterSystems Community! I'm Sidd one of the interns at the Singapore office and I recently had the chance to develop to develop a driver to connect IRIS to Metabase to help some of the Sales Engineers here. I was encouraged to share it here so that if any others have a similar issue they can use the driver and as well as get some feedback on potential improvements. The full GitHub repo with the quick start step, brief overview and the driver building process can be found here. The main purpose of this post will be to go more into detail into the main driver code and talk about ideas on how

🛠️ Managing InterSystems InterSystems API Manager (IAM = Kong Gateway) configurations in CI/CD

🔍 Context: InterSystems IAM configurations 

As part of integrating InterSystems IRIS into a secure and controlled environment, InterSystems IAM relies on Kong Gateway to manage exposed APIs.
Kong acts as a modern API Gateway, capable of handling authentication, security, traffic management, plugins, and more.

However, maintaining consistent Kong configurations (routes, services, plugins, etc.) across different environments (development, testing, production) is a major challenge. This is where tools like
