Hi Community,

In our two preceding articles, we explored the fundamentals of the Interoperability Embedded Python (IoP) framework, including message handling, production setup, and Python-based business components.

In this third piece, we will examine advanced methodologies and practical patterns within the IoP framework that are pivotal for real-world interoperability implementations.
We will explore the following topics: 

✅ DTL (Data Transformation Language) in IoP
✅ JSON Schema Support
✅ Effective Debugging Techniques

Collectively, these features help us create maintainable, validated, and easily troubleshootable production-grade interoperability solutions.

Hi Community,

We're excited to invite you to the next Community webinar presented by George James Software, an InterSystems partner:

👉 Deltanji source control 👈

🗓️ Date & Time: Thursday, April 9th, 4 pm BST | 11 am EDT

The PACELC theorem was created by Daniel Abadi (University of Maryland, College Park) in 2010 as an extension of the CAP theorem (created by Eric Brewer - Consistency, Availability, and Partition Tolerance). Both help design how to architect the most suitable operation of data platforms in distributed environments under the aspects of consistency versus availability. The difference is that PACELC also allows analysis of the best option for non-distributed environments, making it the gold standard for considering all possible scenarios to define your deployment topology and architecture.

The CAP theorem states that in distributed systems, it is not possible to have consistency, availability, and partition tolerance simultaneously, requiring a choice of two out of three, according to the following diagram.

hi 😊,

i'm able to LOAD DATA in IRIS from a rather complex, say Oracle's, query. It works pretty well but requires a target table created aforehand:

LOAD DATA FROM JDBC CONNECTION SOME_OTHER_SERVER QUERY 'complex query here' INTO TargetTable

is there a way to base such target table on the same query ? 
CREATE FOREIGN TABLE seems to require a column definition which I would prefer to be taken from the query
CREATE TABLE AS SELECT seems to be for local queries and other methods, like Linked Table Wizard or %SYSTEM.SQL.Schema.

Hello,

I am working on integrating a CELL-DYN Ruby hematology analyzer (Abbott) with InterSystems Ensemble using the ASTM E1394 protocol over TCP/IP via a Digi One SP serial-to-TCP converter. I am facing a persistent issue where the Link Test keeps failing on the CDRuby side and the Transmit button remains greyed out. I have overridden EOTOptional=1 in the service class file as Ensemble was not able to send ACK after ENQ. Now I am getting below logs like Machine sends ENQ, Ensemble sends back ACK and Machine sends EOT instead of STX.

Hey Community,

Hi everyone,

I was wondering if it is possible to use the InterSystems Server VSCode Extension to work in client side mode but importing locally the content of a project without having to choose the files manually.

It would be awesome to have all project-related assets synchronized in one go. Relying on InterSystems Projects (.prj files) would be convenient for several reasons:

1. Projects bundle different file types (CLS, MAC, INT, CSP). Importing the project as a whole is much more efficient than picking individual files piece by piece.

Claude Code has a strong understanding of IRIS, but unexpected issues still occur.

The first issue is one that has already happened several times and is likely to continue occurring if not properly addressed.

In IRIS, the collation for string data (%String) is set to SQLUPPER by default. As a result, when data is retrieved via SQL, it may be returned in uppercase (for example, when sorting and aggregating with GROUP BY).

Configuring OAuth for InterSystems FHIR Server

Since I started using Claude Code, my motivation to create things has skyrocketed.

Previously, even if I wanted to build something, actually doing the coding felt like a hassle, so unless there was a very strong need, I rarely went as far as programming. But now, if I just jot down the specifications, Claude Code handles the rest automatically, resulting in a dramatic improvement in productivity.

I come from a generation native to ObjectScript, so I used to feel some hesitation when it came to switching to Python.

Hello,

can someone confirm to me if image for docker deployment of IRIS are ready for production? Also what about Healtshare products?

Thank you.

Is there a way to delete a message in a routing rule?  For example, an HL7 message doesn't qualify for a rule, but instead of the message being passed on to the next rule, you delete the message.

I am trying to built a Task that kicks off a Workflow to pull data into HSPD, and when I try to test the Task

I keep getting TestTask+3^OSU.Workday.TerminationsTask.1 *%Exception.StatusException ERROR <Ens>ErrConfigDisabled: Configuration item 'OSU.DataSource.Workday.TermService' is disabled

But within the Namespace the OSU.DataSource.Workday.TermService shows enabled.

Here is my Task that I am using...

Hi all,
I'm trying to learn Intersystems Iris. And I have a question.
How can I use left arrow key with if function. Also if it is possible, teach me that how can I make backspace to edit data?
P.S Sorry for bad English.
new var,key,curPos
w $char(27)_"[2J"_$char(27)_"[H"
s var="12345abcde"
s curPos=$length(var)+1
w $char(27)_"[3;1H"_"First var= "_var
for {
read *key
#; Left Arrow Key
if key="?" {
}
#; Right Arrow Key
elseif key="?" {
}
#; Backspace
elseif key=8 {
}
elseif key=9 {
quit
}
}
w !,"Last var= ",var
Kind Regards,
Ikh

This time, it’s not really programming per se, but we are using React as a front-end development tool for IRIS. When using a web development framework—not limited to React—one key consideration is which CSS framework to use. Up until now, we’ve been using Bootstrap, which is the standard and the easiest to get started with.

However, while it’s easy to use, I felt that it offers limited flexibility for customization. That said, even if we were to switch to another CSS framework, learning it and rewriting everything from scratch would be a significant effort, so we left things as they were.

Is your source control treating your InterSystems IRIS environment like a simple collection of files? Most source control tools lack the native intelligence to handle InterSystems IRIS, which is why your code is treated as such. 

Deltanji is different. It understands how code and other artifacts are stored within IRIS and can manage them directly. This eliminates the friction that other tools introduce to the process. 

Join us for an InterSystems-hosted webinar to see how Deltanji provides an enterprise-grade source control solution that is tightly integrated with your IRIS environment.

I have two RHEL 9.7 servers.  One is running intersystems in docker no problem. But, I have now tried two other servers RHEL 9.7 one, podman and one docker and I get the following.
 

I need to translate these labels on the Whole Record page view:

Anyone knows how to do it?
Thanks

We are working on Disk Consolidation and looking at Class/Globals that are rather large and not being cleaned up by the nightly Purge process. We have implemented DeleteHelper - A Class to Help with Deleting Referenced Persistent Classes | IDC on any Custom Data Classes, and Business Processes (BPL).

We have a bunch of Data Classes, BPL's, and Operations that connect to external MS SQL Server using JDBC to query or write data to using Stored Procedures and Queries. All that Query external tables are using EnsLib.SQL.Snapshot, and this is being written to ^Ens.AppData which is not cleaned up.

A Continuous Training (CT) pipeline formalises a Machine Learning (ML) model developed through data science experimentation, using the data available at a given point in time. It prepares the model for deployment while enabling autonomous updates as new data becomes available, along with robust performance monitoring, logging, and model registry capabilities for auditing purposes.

InterSystems IRIS already provides nearly all the components required to support such a pipeline. However, one key element is missing: a standardised tool for model registry.

Hi Community,
