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?

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

Using %Net.WebSocket.Client

Hi Guys,

I'm trying to use %Net.WebSocket.Client to collect data from a sever,

and part of that I needed to implement Two classes (SX3.Production.HTTP.AdvCredenials & SX3.Production.HTTP.AdvListener) as below for the purpose of Credentials & EventListener properties,

I am looking to create a Python virtual environment (venv) so that my imported/installed python packages can be separate on different namespaces in IRIS. I am able to go and create an environment, activate it, and install packages, but I am not sure how to ensure that Embedded Python methods actually point to this virtual environment.

Is the best solution to just load the virtual environment at runtime, in each method? That seems like a bad solution. Has anyone run into this and found a good solution?

I have notified that on several servers the IRISTEMP database is reported as only a few GB in size while on the disk where it's located, the IRIS.DAT file is much bigger (eg: 3GB reported in Portal (including free space) while file on the disk file is 121GB). The last modification date of IRIS.DAT is recent so I'm not looking into a location no more in use.

Is there an explanation for that difference in size ?

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.

I have a class with a projection that creates some persistent classes (chunks) and a non-persistent "Daemon" class that I want to have running in the background, doing some processing. The daemon needs to look at the "chunk" classes, and I want it to be simple to start the daemon -- I am currently calling the daemon's start method at the end of the CreateProjection method.

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.

What is wrong?

Thanks in advance

#InterSystems Demo Games entry

⏯️ The Ultimate 3D Industrial Simulation powered by a Game Engine with InterSystems IRIS

In this demo, InterSystems IRIS Interoperability comes alive in an amazing, game-like user experience based on our Ultimate Control Tower demo. We visualize machines in a virtual 3D factory building, interacting with InterSystems IRIS in real time—displaying current statuses and sensor data, simulating machine outages and predictive maintenance scenarios, and triggering workflow tasks and actions in InterSystems IRIS. By using a mobile app on a tablet—and even a VR headset for a fully immersive experience—we unleash the power of InterSystems IRIS.

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.

I would have to clear my cache files or browser history for it to reload and work.

I'm trying to open a TCP connection to a remote system. The Caché command I'm using to open the connection is OPEN "|TCP|"_PORT:(IP::"PSE"):10 where PORT is a port number in the range 40000 to 40100 and IP is a standard IPv4 addess like 10.200.100.50
the connection appears to open because $TEST becomes 1.
I'm then writing to the open port with USE "|TCP|"_PORT:(::"S") WRITE "some text",*-3
It's a windows system

I like Application Error Log a lot, both for its full stack and a big list of variables. I'd like to "hack" this functionality and record the same in this log when a certain variable has a certain value. This quasi error should not be visible to the user, and it should not interrupt the application flow. Is that possible?

Throwing an error in a try-catch block does not record the error, tested. I am considering recording variables and the stack differently, I know how to do both, but that would miss the nice Application Error Log functionality.

I am trying to get the value of a Submit button on a CSP object page.

<input type="Submit" value="Assign" name="action" id="action">

I tried getting it thru $GET(%Request.Data("action")), but it throws an Undefined error. Isnt $GET supposed to handle it if its undefined anyway?

How do I get the "value" of the button pushed when the form is set to POST?

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

Hi all,

We're developing a medical appointment app that connects doctors' schedules to an appointment provider.

The provider is returning us the appointment in the following format:

Thu Jul 03 08:20:00 CEST 2025

It means, 03 july 2025 at 08:20:00 Central European Summer Time (UTC+2)

But we need the following format:

2025-07-03 08:20:00+02:00

Is there any option to convert zone time code (CEST) to a UTC+x ?

How to convert zone time code (CEST, CET, ET, EDT, etc..) in its zone time in UTC (UTC+2, UTC+1, UTC-5, etc..) ?

⏯️ Eliminating Waste in Healthcare Supply Chains

Between recalled supplies, expired inventory, and rogue spending, an estimated $25 billion per year goes to waste in healthcare supply chains. We know how critical supply chain is in healthcare, so we know this is a problem worth solving! What could a proposed solution look like? Watch and find out!

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.

A workload averaging 1000 1-kilobyte queries per second is compared with another involving 10 1-terabyte queries per hour

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.
