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 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..) ?

Hello everybody,

I would like to export project contents using Visual Studio Code, as well as I do with InterSystems Studio.

However, while attempting the export through the InterSystems extension I get the following error:

- There are no folders in the current workspace that code can be exported to.

These are the step to reproduce my error:

Hi,

I'm trying to install NodeJs (javascript runtime environment) in IRIS container so I can execute JS files?
It was easy to install it outside the container but I got the attached error when trying in the container:

Hello, good morning, thank you so much for reading this question. ☺️🙂👍

We are developing a code to get information about our Production's items: services, processes and operations.

We know we can get various configurations of a given item: Category, Port, Enabled...

But we wonder how we could get the date time of the last mesage (most recent) received in an item.

To give a code snippet a small section of the code we have developed (and tested), it looks like:

Hi Community

I'm working on a complex piece of rules that needs to check each OBX and evaluate if 3 of the fields match certain criteria. I've tried to achieve this using a Foreach loop, which does work, however it is not as clean as I wanted it. I was hoping I could assign temp variables inside the foreach loop to make the rules more easier to read, for example @testCode @resultText. This is not support as you can only assign inside a when condition. Before I raise this as an idea, i wondered if there was an alternative way to achieve the same thing?

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?

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

My HL7 message got "AR" (rejected ack code) and went to the suspended queue. I re-submitted it (without editing it) but forgot to write down the details before doing so. It got "AA" and everything works fine from there.

Now (the next day) I want to check with the downstream system why they returned "AR" initially. Is there a way to search for the original message the got an "AR", along with any returned error message please?

Thanks

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).

I seem to remember making this work before, but I'm not having any luck digging up examples.

I've defined some custom properties for a business operation that could definitely benefit from having popup descriptions available in the Production Configuration. I have triple-slash comments before each property that do just that in the source. I thought those provided the text for the popup descriptions when clicking on the property name, but apparently not.

Any thoughts?

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 was wondering if anyone had a way to automate creating the Query String for a FHIR Request?

Using HS.FHIRServer.Interop.Request in my development I have to specify the following...

I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?

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.

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 ?

In IRIS, every time a request need to be processed, a specific IRIS process (IRISDB.EXE) need to be assigned to handle that request.

If there is no spare IRIS process at that time, process will need to be created (and later destroyed). On some Windows systems (especially with security/antimalware solutions being active) creating new processes can be slow, which can results in delays during peak times (due to inrush of requests).

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:

I have an application that is requires an Encoded HL7 message sent over SOAP over HTTPS using SSL/TLS... the Response that is return is also encoded, which I know how to Decode but not sure when I Decode the response how to Extract the HL7 message to send back to the router.

How do I capture the Routing Source System and parse the encoded message back into an HL7 format that would show on the trace viewer?
