InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Hi folks!

I'm building a very simple REST API.

But before testing it via a Web Server what I want to make sure that REST API methods work in principle.

Is it an easy way to "fake" the web-server request and get a result e.g. of the method with signature like that?

ClassMethod GetAllRecords(pRequest As %CSP.Request, pResponse As %CSP.Response) As %Status

e.g. calling it in Terminal?

Introduction

In InterSystems IRIS 2024.3 and subsequent IRIS versions, the AutoML component is now delivered as a separate Python package that is installed after installation. Unfortunately, some recent versions of Python packages that AutoML relies on have introduced incompatibilities, and can cause failures when training models (TRAIN MODEL statement). If you see an error mentioning "TypeError" and the keyword argument "fit_params" or "sklearn_tags", read on for a quick fix.

Hello,

Very much keen if we could gather the per namespace and business component utilization of InterSystems cache server.

For e. I have a PRD server where its CPU utilization is at max all the time and I want to know which namespace and its business process (service/Operation/Process) is utilizing what number of CPU and memory.

** I can get the CPU and Memory utilization per Cache.exe and PID, but not able to get the Namespace and ConfiguratioName to which that particular PID belongs.

Thank you,

The latest "Bringing Ideas to Reality" InterSystems competition saw me trawling through the ideas portal for UI problems to have a go at.

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or 

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

Hello IRIS community,

InterSystems Certification is currently developing a certification exam for InterSystems IRIS SQL professionals, and if you match the exam candidate description given below, we would like you to beta test the exam! The exam will be available for beta testing starting May 19, 2025.

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:

We have an ObjectScript application that runs in Cache' and IRIS. Our typical installation involves a .zip file containing several files necessary for the installation and operation of the application. Steps are: expand the .zip file to a folder that will not be used by the application. Do ^%RI for the installation routines in the production namespace. Do the Installation routine. We have a customer that is trying to do a silent installation. He does not want to have to respond to any prompts on the installation.

Hi,

I tried to create what is know as a "class variable". As far as I understand the only analogy to class variables would be the "class parameters".

I tried to use a class parameter but I cannot change its value at runtime.

Parameter STATUSES = {{}};

Property repr As %String;

Method %OnNew(repr) As %Status
{
w ##class(Test...).#STATUSES
w ..#STATUSES

...

}

The InterSystems platforms have always offered dynamic documentation of the packages and classes in a namespace, a feature known informally as Documatic. But what if you need to publish this class reference information on a website without requiring the site to be connected to an IRIS server containing the actual classes?

Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance. Do you know all the parameters that affect the memory allocated by IRIS ?
