Faced with the enormous and evergrowing amounts of data being generated in the world today, software architects need to pay special attention to the scalability of their solutions. They must also design systems that can, when needed, handle many thousands of concurrent users. It’s not easy, but designing for massive scalability is an absolute necessity.

Software architects have several options for designing scalable systems. They can scale vertically by using bigger machines with dozens of cores. They can use data distribution (replication) techniques to scale horizontally for increasing numbers of users. And they can scale data volume horizontally through the use of a data partitioning strategy. In practice, software architects will employ several of these techniques, trading off hardware costs, code complexity, and ease of deployment to suit their particular needs.

This article will discuss how InterSystems IRIS Data Platform supports vertical scalability and horizontal scalability of both user and data volumes. It will outline several options for distributing and partitioning data and/or user volume, giving scenarios in which each option would be particularly useful. Finally, this paper will talk about how InterSystems IRIS helps simplify the configuration and provisioning of distributed systems.

As foreign tables are behind a paywall (booo); we have a external cache system using the intersystems ODBC driver or usually a .jar CacheDB.jar. 

The requirement is :

"Create a copy of the external table once a day to perform comparisons to detect changes"

We could go full code and this is what we will do but trying the following should ideally work 

CREATETABLE Sample.YoungPeopletwo ASSELECT *
FROM Pennine_TIE_Clinicom_Link.PMISPECIALREGNCA
WITH STORAGETYPE = COLUMNAR

This resulted in 

[SQLCODE: <-400>:<Fatal error occurred>]

Hello,

I need to expose InterSystems HealthInsight dashboards over the internet to external operators. The authentication flow is managed externally. When a user is authenticated, our system receives an HTTP request with specific headers (e.g., operator’s fiscal code and hospital identifier) that we need to extract in order to:

• Authorize the user to access the dashboards.
• Apply row-level security on the dashboards, filtering the data by hospital and user role.

I created a new Web Application on IRIS as shown in the screenshot:

I follow this page of the documentation for the settings: https://

Hi,

Using the below code to connect and get data from a server:

Class SX3.Production.HTTP.AdvCredenials Extends (%RegisteredObject, %Net.WebSocket.ICredentials)
{Method GetUsername() As %String
{
quit ""
}/// Returns the password to use for authentication with the web socket
/// @API.Overrideable
Method GetPassword() As %String
{
quit ""
}Method GetSSLConfiguration() As %String
{
q "RTLS"
}}

Class SX3.Production.HTTP.AdvListener Extends (%RegisteredObject, %Net.WebSocket.IEventListener)
{Method OnOpen()
{

if $increment(%ct("O")) set io=$io use 0 write "OPEN",! break:$get(%b) use io
}/

So I would like to start a production with a service that has an SQL trigger for after and INSERT. Then I would like it to start a process. Could someone help me in the direction of a solution, please and thanks.

Hi,

We have just upgraded the Trusts test Health Connect instance from 2021.1 to 2025.1 and now the the Rules and DTL editors, in the Management Portal, timeout after 10 - 20 minutes of inactivity.
In 2021.1 we were able to disable this timeout using: set ^EnsPortal("DisableInactivityTimeout","Portal") = 1, however this no longer works with 2025.1, and is being ignored.
It may be being ignoring this global setting because the editors are no longer using the default Web Application for the Namespaces, and are using the: /ui/interop/rule-editor and /ui/interop/dtl-editor Web Applications.

Hi Guys,

I'm using below to retrieve advertising data from Cassia AC server, but the problem is that its a live connection so the Httprequest.Get(HttpURL) call will hang and doesn't exit & return the data so is there a way for return and after say 30 secs from this live data? or is there something EventSource or something similar where I can pass the URL call then after say 30 secs I can end & exit the call to return the collected data?

Hello InterSystems Community,

I'm working with HealthShare, and need to create a user account for our development environment with specific access requirements. This user will need only to:

    Review messaging and environments
    See production and namespaces
    NOT modify anything (read-only access)

After reviewing the documentation on user roles and rights management, I can see the default roles available in our system include:

Ensemble/Interoperability Roles:

    %EnsRole_Administrator - Interoperability Administrator
    %EnsRole_AlertAdministrator - Interoperability user with administrative

REST API (Representational State Transfer Application Programming Interface) is a standardized way for web applications to communicate with each other using HTTP methods like GET, POST, PUT, DELETE, etc.It's designed around resources, which can be anything from a user to a file.Each resource is identified by a unique URL, and interactions with these resources are stateless, meaning each request from a client to a server must contain all the information needed to understand and process the request.

Dear community, I have a confession to make.I have not gotten over Zen yet.Alas, all good things must come to an EOF, so I am currently learning about Angular.I am working on proving to myself that with the right back end and Angular components, I can deliver to myself and my team a very Zen-like experience in this environment.Since this is my first attempt, here is a fair warning: I will be providing some rather large code samples before discussing them.Please warm up your mouse and hand for extensive upcoming scrolling!

We wonder if there is a way to filter EnsLib.DICOM.Document, by using its DataSet properties on the Message Viewer.

For example, we would like to find the following DICOM.Document which DataSet.AccessionNumber is SR115985013100

By using the Message Viewer Filter we have tried the following:

Because when we look fod a Body Property of the EnsLib.DICOM.Document it shows this drop down menu:

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

• How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
• Do I have to then do another "fromDao" to pull the list into string format?
• How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

For my intern project, I am building a Flask REST API backend. My goal is to host it on InterSystems IRIS using the WSGI interface. This is a relatively new approach and is currently only being used in a handful of projects such as AskMe. To help others get started, I decided to write this article to simplify the process.

Creating a Basic Flask App

First, let’s create a minimal Flask application. Here is the code:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

@app.route('/test')deftest():return"Test"if __name__ == "__main__":

Hi Developers!

There is a free ObjectScriptQuality tool for ObjectScript developers who upload solutions on GitHub. This tool helps developers validate ObjectScript code using a variety of rules, based on common code errors.

There are currently 16 rules in this tool, but there are definitely many more rules to consider when testing ObjectScript code.

Could you suggest any other rules to add to this tool?

Introducing Care Compass: AI-Powered Case Prioritization for Human Services

In today’s healthcare and social services landscape, caseworkers face overwhelming challenges. High caseloads, fragmented systems, and disconnected data often lead to missed opportunities to intervene early and effectively. This results in worker burnout and preventable emergency room visits, which are both costly and avoidable.

Care Compass was created to change that.

Hello,

I'm trying to connect a Python backend application to an InterSystems IRIS Community Edition instance running in a Docker container on an AWS EC2 instance. I'm facing persistent connection issues and an SSL Error despite the Superserver apparently having SSL disabled. I'm hoping for some insight into what might be causing this contradictory behavior.

My Setup:

• InterSystems IRIS: Community Edition (Docker image intersystems/iris-community:2025.1)
• Deployment: AWS EC2 (Ubuntu) instance.
• Port Mapping: Host port 9091 mapped to container port 1972 (Superserver). Host port 9092 mapped to
