Question PaulSomebody · Oct 3, 2025

How do you assign a property in a RUL (not a DTL or BPL) from a function value?  I've tried with the package/classname, without, with .., without and even looked all the way down to the parser but still can't see how.  There is no examples and the documentation doesn't help

So this works

<assign property="RuleActionUserData" value="&quot;A01&quot;"></assign>
 

This doesn't complile

<assign property="RuleActionUserData" value="##class(SomePackage.SomeClass).EventTypeToHL7Type(Document)"></assign>

SomePackage.SomeClass extends EnsRules and the method is a classmethod and final

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

If you are looking for high availability you could use:

a) Kong Traditional Mode: Multiple Node Clusters

b) Hybrid Mode

c) DB-less Mode

Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.

Hi Community,
I’m trying to execute a directory query in InterSystems IRIS using %SQL.Statement, but encountering an unexpected error.

Details:
The following command confirms that the directory exists:

Set dirPath="\\MYNETWORK_DRIVE\DFS-Shared_Product\GXM"
Write ##class(%File).DirectoryExists(dirPath)

It returns 1, meaning the path is valid and accessible.

However, when I try to execute this SQL query:

Set File=##Class(%SQL.Statement).%New()
Set Status=File.%PrepareClassQuery("%File","FileSet")
Set Result=File.%Execute(dirPath)
If Result.%SQLCODE {
    Write Result.%Message
}

Nearline FHIR® Ingestion to InterSystems OMOP from AWS HealthLake

This part of the OMOP Journey we reflect before attempting to challenge Scylla on how fortunate we are that InterSystems OMOP transform is built on the Bulk FHIR Export as the source payload.  This opens up hands off interoperability with the InterSystems OMOP transform across several FHIR® vendors, including Amazon Web Services HealthLake.

Why This Matters

Managing IAM can be tedious when done manually — especially when your APIs are already well-documented using OpenAPI (Swagger) specs. Wouldn't it be great if you could automatically generate Kong services and routes directly from your OpenAPI spec?

That's exactly what this ObjectScript method does: it reads an OpenAPI 2.0 spec stored in the XData block of your spec class and generates a decK-compatible YAML file that can be used to sync your IAM configuration.

This approach:

  • Reduces manual configuration errors
  • Keeps your gateway in sync with your API spec
  • Speeds up deployment

InterSystems FAQ rubric

The ^%GCMP utility can be used to compare the contents of two globals.

For example, to compare ^test and ^test in the USER and SAMPLES namespaces, it would look like this:
*In the example below, 700 identical globals are created in the two namespaces, and the contents of one of them is changed to make it the detection target.

USER>kill^test
USER>for i=1:1:100 { forj=1:1:7 { set^test(i,j)="Test"_i } }
 
USER>zn"samples"// change namespace to SAMPLES
SAMPLES>kill^test
SAMPLES>for i=1:1:100 { forj=1:1:7 { set^test(i,j)="Test"_i } }

Hi community,

A colleague gets ERROR #822: Access denied every time he tries to log in via Management portal. It is NOT the case of wrong credentials: I reset his password password to a temporary one so it would prompt him to create a new one upon first login. He did get the prompt, changed his password and his next attempt at logging in displayed the same error.

The audit log record displays this:
Error message: ERROR #862: User is restricted from running application /csp/sys/op, %Admin_Operate:U required -- cannot execute.

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

Hi Community,

This is my first post in the developer community - would appreciate any feedback!

For testing or demo purposes, you may want to send emails from your Interoperability Production. In this post then I will walk you through connecting an InterSystems IRIS Production to Gmail so you can use it to send emails alerts.
 

1. Set up a new Gmail

  1. Create a new Gmail account and document the username and password for future references.
  2. Go into the Settings icon on the top right corner of the gmail interface then click on "See all settings".

Introduction

HL7 messages often contain multiple repeating segments such as NTE, AL1, OBX, ZTX, DG1, and others. These segments sometimes require individual processing and routing to different downstream systems. This technical paper introduces a configurable template designed to automate the splitting of these repeating HL7 segments, improving message handling and integration efficiency.

Question Ashok Kumar T · Sep 28, 2025

Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

  1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
  2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

Hi,

Just thought I'd share quite a handy hook that has helped me out when developing on Health Connect Cloud with VS Code and GitBash. When developing on Health Connect Cloud, if changes are made directly on the server such as routing rules or component deployments, they aren't automatically included in source control, therefore you must export from the server into your local files and push to your remote repo. I'm sure there are easier methods to deal with that which I'm in the process of testing, but as a quick solution I thought it would be handy have a pre-commit hook which triggers a reminder in GitBash - see below.

Building a Sensor Data Demo with Spring Boot and InterSystems IRIS

In the era of IoT and connected devices, sensor data is everywhere—tracking temperature in logistics, monitoring equipment performance, or recording environmental conditions. But capturing, storing, and analyzing this data in real time requires more than just hardware sensors.

It’s a practical example that combines Spring Boot, InterSystems IRIS, and a simple sensor simulation script to show how sensor data can flow from generation to storage and alerting.
Basically, the idea of ​​this project is to show all the integration

InterSystems FAQ rubric

One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Note that the number of parallel processes cannot be specified, as it is automatically adjusted according to the number of CPUs.

Following on from JediSoft’s announcement of the general availability of JediSoft IRISsync®, I wanted to show how it can help prevent configuration drift and ensure your failover is always ready. 

When managing InterSystems IRIS production servers, even a minor configuration change can cause significant issues if it’s not replicated in your mirror environments. Often, these differences go unnoticed until your failover environment breaks.

This common, but critical, problem can lead to unexpected downtime at a vital moment and impact your business continuity.

Hi everyone,

I'm currently seeking a new position related to InterSystems technologies. My major skill is app integration and data flow development on the InterSystems IRIS platform (Interoperability). I develop high-load, mission-critical software. My coding background on Cache ObjectScript includes hundreds of data flows, thousands of Production business hosts, dozens of APIs, and other solutions on InterSystems IRIS. I worked to integrate such applications as SAP S/4HANA, Oracle Siebel, SAP Commerce Cloud, many custom apps, and all that can be integrated. I have also gained experience in various areas, including SQL, Java, Docker, IRIS administration, Apache Kafka, and Flutter (Dart).

My problem was separating HL7 messages by message type.  I had to create multiple File Operations.  So I with custom code I am able to use 1 File Adapter for 1 interface and multiple message types.  I did experiment pulling the MSH 4 out of the raw content to further access dynamic information, but that may open a need for more robust error checking / lookup default actions.

Using the recommended naming convention of "To_FILE_<IntegrationName>"

I decided to use a generic file name and path in the default settings.

I created a custom class that extended the EnsLib.File.OutboundAdapter  With some
