Hi, every one. Again, it's me!!😀😀
Recently I was trying to organize some learning materials for InterSystems IRIS😆, and realized that the resources are actually quite scattered.🤐
So I put together a list here—grouped by categories—for anyone who:
Also adding some of my own experience on what worked (and what didn’t, may be only not work for me🤫🤐).
If you don’t know where to begin, start here:
While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together.
1. Working with Dynamic Objects:
Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.
InterSystems FAQ rubric
There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.
Temporary Globals and the IRISTEMP Database
By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

This past weekend we ran into something odd. When we failed over our mirror from 2022.1.3 to 2025.1.3 the one of the Business Rules that was on what became the Primary (2025.1.3), had a rule within it that was removed back in January. When the Failover occurred, we had to scramble to backup, disable, and remove the Rule that shouldn't have been there.
Both the Data and Code live within the same IRIS.dat that is the main MIRROR database for that Namespace.
If this happened to one Class file, could it happen to others we do not know about?
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 Developers!
Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices?
if 10K lines OK? How do you cope with it? Please share?
A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.
A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.
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).
Hi developers!
In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:
Classmethod Planets() as %DynamicObject {
set val1="Jupiter"
set val2="Mars"
// this doesn't work! cannot compile
return {"value1":val1, "value2":val2}
}So I need to do the following:
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.
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...
Class OSU.Workday.TerminationsTask Extends %SYS.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.
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,
An error occurs during the analysis process in the FHIR SQL Builder. How can I identify the exact cause of the error?

1. HL7-to-SDA3 transformations are in use 2. Medication-related messages include TQ1 segments 3. TQ1-3 Repeat Pattern contains multiple repetitions |
An issue has been identified in the HL7-to-SDA3 transformation logic that can cause an infinite loop when processing certain medication-related HL7 messages.
Hi All,
First I want give a Shout Out to @Theo Stolker and @Rupert.Young. Because they helped me with the solution.
When you're using the EnsLib.SQL.Snapshot as a Property in the Response Message to return Snapshot data (,e.g.: from Business Operation to Business Process,) the Snapshot data won't be cleaned with the Purge messages task/service.
{
Property SnapshotProp As EnsLib.SQL.Snapshot;
}
The data will be stuck in the global: ^Ens.AppData. You can find it with this query in System>Globals: ^Ens.AppData("EnsLib.SQL.
Working in healthcare IT as a young developer, especially on InterSystems TrakCare, you quickly realize one thing: it’s not just about HL7 messages or backend integrations. A hugepart of making TrakCare work smoothly for hospitals comes down to how it’s configured, customized, and supported on the application side.
That’s where people like me come in—techno-functional developers who understand both the tech and how it impacts actual hospital workflows.
Our role sits right in the middle.
FHIR (Fast Healthcare Interoperability Resources) is the modern standard for storing and exchanging clinical data. But once your data is in a FHIR server, how do you actually explore it? FHIR data is stored as JSON — powerful, but not practical to read directly. I wanted a tool where you could click on a patient, see their conditions, medications, lab results, and more — in a clean, readable format. So I built the FHIR Patient Viewer.
The app runs entirely in Docker and connects directly to an InterSystems IRIS for Health FHIR server.
Hi everyone,
I’ve configured an integration scenario in InterSystems IRIS with a Business Service exposed as a SOAP web service. Everything works correctly when the web application allows unauthenticated access.
However, when I switch the web application to require Basic Authentication, I’m unable to get it working properly. I have configured a resource and assigned it to both the web application and the user I’m using for the request, but I consistently get login failures (visible in the audit log).
For example in %Library.File Class Documentation, FiieSet query is listed as:
"Selects Name As %String, Type As %String, Size As %BigInt, DateCreated As %TimeStamp, DateModified As %TimeStamp, ItemName As %Stringof ..."
How to obtain a "real" syntax?
Thank you.
Our Pharmacy team would like us to convert...
¼ test character and ½ test character and ¾ test character andto more like
1/4 test character and 1/2 test character and 3/4 test character andIs this possible?
