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

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.

159

If you want to specify the database directory you want to refer to, run the following:

I feel I may be in the "people unclear on the concept" group here.

System Default Settings is a great mechanism, and we use some custom code to deploy it in our pipeline after environment specific changes have been applied to the content. However, we are trying our best to reduce the amount of custom code we use in our system that does not relate directly to the business. For CI/CD, this means we are trying to leverage IPM for the heavy lifting.

Is there a method for handling System Default Settings in IPM that I am just overlooking?

Are you curious about how to run Python scripts directly in your InterSystems IRIS or Caché terminal? 🤔 Good news it's easy! 😆 IRIS supports Embedded Python, allowing you to use Python interactively within its terminal environment. 

How to access the Python Shell?

To launch the Python shell from the IRIS terminal, simply run the following command:

do##class%SYS.Python

This opens an interactive Python shell inside the IRIS terminal. From here, you can write and run Python code just as you would in a normal Python environment.

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

Good morning everyone,
In the facility we're working in, we have two separate installations for testing and production. In the test environment, we have production processes running properly, and we need to replicate production processes and settings in the production environment. Until now, when we move from a test environment to a production environment, we currently export the test classes, import them into production, and manually configure the production environment by connecting Services, Processes, and Operations and configuring the settings.

Hi, Community!

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?

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).

Optimizing Performance of Apache Web Server and Web Gateway

By Patrick Jamieson, M.D., Product Technical Manager, InterSystems IRIS for Health

When working with InterSystems IRIS or IRIS for Health, an external web server like Apache2 or NGINX is essential for managing HTTP workloads, especially for FHIR servers Starting with version 2023.3, the private Apache server was removed from the installation kit (except for Community Editions and Health Connect).

Hi,

To add or get information about a user for the management portal you can [within the portal]:
 System Administration > Security Management > Users 

Is it possible to:

1. List a user, user's properties including roles

2. Add a user and set user's properties including roles

3. Set a user's password

for the management portal using a program eg. Objectscript and/or SQL?
If so, how can this be done?
It would be great if you have examples.

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.

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.

Dear InterSystems-Maintainer Team,

I am currently conducting a comparative evaluation of FHIR clients as part of my
bachelor thesis in health informatics. One of my evaluation criteria is the response
time to support inquiries.

Therefore, I would like to kindly ask the following question as part of my analysis:
How can I read and write custom FHIR extensions using your client library?

If available, could you point me to any documentation or examples?

Many thanks for your time and support!

Kind regards,
Rüya Gökoglu

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.

        Catch ex Set 

Cant seem to find the %Logger class either.

I'm following this guide as well as the sample.cs file and getting an error message on this line
cache_connection.Connect();

The error is:
Caught GlobalsException: lc_conn::connect_device returned Db_err: source: lc_conn::connect()  message: lc_conn::connect: CacheSecureStart returned -15: <ACCESSDENIED>

I've tried many variations of Namespace + Username + Password and they all result in that error, even though I can connect to the namespace just fine using other means.
