in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?

Hello Community

The InterSystems IRIS Community License for Iris version 2024.1 is about to expire. I would like to know if there’s a way to extend this license, or if I need to upgrade to the latest version of Iris.

Thanks!

Hi Community!

We’re pleased to announce that several Early Access Programs (EAPs) are now open for registration. These programs provide developers with the opportunity to explore upcoming features and technologies from InterSystems before their general release.

By joining an EAP, you can:

• Evaluate and test new functionality
• Provide direct feedback to product teams
• Help shape the future direction of InterSystems platforms

If you're interested in contributing to the evolution of our tools and getting early insight into what's coming next, we encourage you to review the following available programs and sign up:

At hackathons that InterSystems participated and I supported, many students were asking how all their teammates could use the same IRIS database that they spun up in a container. I suggested using ngrok to expose their localhost IRIS and realized we don't have documentation on that. Hence, I thought this would be great to let more people knwo about this powerful technique for enhancing collaboration during development and testing.

Step-by-Step Guide to Exposing InterSystems IRIS with ngrok

This will be an introduction to Python programming in the context of IRIS.

Before anything I will cover an important topic: How python works, this will help you understand some issues and limitations you may encounter when working with Python in IRIS.

All the articles and examples can be found in this git repository: iris-python-article

How Python works

Interpreted Language

Python is an interpreted language, which means that the code is executed line by line at runtime even when you import a script.

What does this mean ? Let's take a look at the following code:

Hello Again,

Hey Community!

We're happy to share the next video in the "Code to Care" series on our InterSystems Developers YouTube:

⏯  Agentic AI in Action: Building a Decision-Making Loop with LLMs

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

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:

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"
}}

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,

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:

There is nothing in the application error log. How can I troubleshoot this?

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. This statelessness, along with the use of standard HTTP methods, makes REST APIs highly

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! Also, a note on the code snippets: many of them are labeled

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.

⏯  InterSystems IRIS: Easy to Consume and Easy to Use @ Global Summit 2024

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?

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class. Then also there is a screenshot of my web application I made specifically
