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.

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:

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 ?

Hi IRIS experts!

I have a parameter in a class that stores a global name:

Parameter GlobalName = "^AGlobal";

then I'm trying to call it as:

set gn=$name(..#GlobalName)

to use it later as:

set @gn@("index")="value"

But! I'm having syntax at set gn=$name(..#GlobalName)

What am I doing wrong?

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

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..) ?

Hi,

I'm trying to install NodeJs (javascript runtime environment) in IRIS container so I can execute JS files?

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?

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:

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

Digital health solution providers face increasing pressure to integrate complex health data systems while ensuring scalability, security, and compliance with standards like HL7 FHIR. Fast Healthcare Interoperability Resources (FHIR) has revolutionized health data exchange by offering a standardized framework that allows diverse health IT systems to communicate effortlessly. But simply adhering to FHIR standards isn’t enough to overcome the intricacies of health data integration. Solution partners must leverage advanced architectural components like FHIR brokers, façades, and repositories to build scalable and efficient solutions. InterSystems offers all the essential features you need to implement FHIR for your health data, whether on-premises, in a public cloud, or as a cloud-based service managed by InterSystems.
