My intention is to show how simple it is to generate a lookup table taking into account the information received in our HL7 messaging. The HL7 message lookup table provided by IRIS is certainly sufficient for most of the searches we want to perform, but we always have that special field in our HIS, LIS, RIS, etc. that we'd like to search by. But that's in a segment outside of that lookup table. That field forces us to generate a specific search using the expanded search criteria. We'll likely have many messages, and we'll also have to filter by date and time so we don't timeout.

• /interop - A ping endpoint to test the interoperability framework of IRIS.
• /posts - A

Here's a sample code to display JSON or dynamic object.

It shows how to iterate over object, get property values and their paths.

Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on: 

• which one specific function is being called between two calls of $$someFunction^Lib(x),
• which one specific

Hello, dear members of our developer community!

In today's article, we're going to take a look at one of the latest remote monitoring features that have been added to the product for our IRIS instances. I'm talking about OpenTelemetry support.

Before we start with some intermediate and advanced topics, I would like to sum up some more general points. They are subjective, of course, so I will be happy to discuss them if you have other opinion or better arguments for any of them.

The list is not comprehensive and this is intended, cause I will cover some topics in future articles.

Tip 1. Follow official styleguide

Angular is quite strict in terms of limiting the possible architecture of an application, but there are still many places in it that allow you to do things your own way.

1. A Motivating Example

Embedded Python has been around for a while. You probably followed the tutorials and learned about it. However, if you've tried to combine Python and ObjectScript in real development work, you probably ran into situations where you get an error message like this:

USER>Do##class(MyClass).SomeMethod()

ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'ZeroDivisionError'>: division by zero

It's a long string for limited information. All we know from this message is that a Python error occurred where (a) the error type is ZeroDivisionError; and (b) the error

Two big changes for the TestCoverage open source tool: Embedded Python support, and a new UI 

Embedded Python

Previously, TestCoverage could only track unit test coverage for code written in ObjectScript. It would ignore code written in other languages like Python in the coverage statistics.

As more and more IRIS application code is being written in Embedded Python instead of just ObjectScript, it's critical that TestCoverage can include coverage results for Embedded Python code.

I want to save and compile a class in VS Code, but I get the error:

Any ideas what is wrong?

We are glad to announce that DBeaver has supported InterSystems IRIS out-of-the-box since version 7.2.4. You don't need to configure it manually anymore, just find the IRIS icon in the Connections list. 

Hey everyone,

I'm diving deeper into Caché ObjectScript and would love to open a discussion around the most useful tips, tricks, and best practices you’ve learned or discovered while working with it.

Whether you're an experienced developer or just getting started, ObjectScript has its own set of quirks and powerful features—some well-documented, others hidden gems. I’m looking to compile a helpful set of ideas from the community.

Some areas I’m especially interested in:

• 💡 Clever use of %INCLUDE, macros, and preprocessor directives
• ⚙️ Best practices in class-based development using %Persistent,

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:

• LEVEL is a pseudo-column used in hierarchical queries (CONNECT BY). It starts at 1 and increments by 1.
• CONNECT BY LEVEL <= (...) determines how many rows to generate.
• The difference between the two dates plus one gives 11, so the query

⏯ It's CLEAR - Re-Imagining the Digital Front Door @ Global Summit 2024

Is anyone using DICOM Interoperability in IRIS for Health configured in Mirror?

I'm asking because I'm not sure how to handle where the DICOM messages are stored.

For some reason DICOM use the filesystem to store raw messages, the directory used can be configured in the StorageLocation production settings, obviously this is a big issue if/when a mirror failover occur.

Unfortunately in IRIS it's not possible to change the DICOM storage from file stream to global stream.

Has anyone came across this issue?

Hello Community

I have previously experimented with embedded Python in IRIS; however, I have not yet had the opportunity to implement IRIS using native Python. In this article, I aim to outline the steps I took to begin learning and implementing IRIS within the Python source. I would also like thank to @Guillaume Rongier and @Luis Angel Pérez Ramos for their help in resolving the issues I encountered during my recent PIP installation of IRIS in Python, which ultimately enabled it to function properly.

Let's begin to write IRIS in python.

I have created a new docker stack with webgateway and IRIS for Health 2025.1. I have mapped the posts of wegateway like this:

• 8743:443
• 8780:80

I can access IRIS portal through 8743 without problems.

I also have created a FHIR repository, and I'm able to access it through 8743 port.

I have a web application, in another server with another domain, that connects to this FHIR repository. I have configured in FHIR endpoint the allowed origin to the domain of this application. But when I try to connect from this application to FHIR repository I have this error on Webgateway:

As Health Applications are moving to the Cloud, how have you handled communication from the Application to your instances via HTTPS?

Trying to figure out the best path on designing the proper workflow to allow these messages to be allowed to be eventually sent to our EMR to post to the patient chart.

We are very wary of opening a connection from the internet to our instance of Health Connect.

Hello everyone, let me introduce, one of my latest projects. It is a DataSource plugin for Grafana, which can connect directly to InterSystems IRIS and gather any data (in the future). 

Hello,
I have created this script that does lot of writes to a single global. DB write performance is much slower than expected (compared to another similar systems).

I have notified the following : 

• CPU usage does not reach 100% on a single core (eg: 25% of total CPU usage should be seen on a 4 cores system).Instead, much lower CPU usage is shown (with some drops to 0% from time to time).
