Hello Community,

I am facing a JDBC connection issue after migrating from Caché 2016 to Caché 2018.1. When I attempt to connect using the following connection settings:

CACHE_DATASOURCE_URL=jdbc:Cache://localhost:1972/TEST

CACHE_DB_USERNAME=test

CACHE_DB_PASSWORD=test

I consistently receive the following error:

[Cache JDBC] Communication link failure: Access Denied

This configuration worked perfectly with Caché 2016. I have verified the following:

I'm using this service to create a FHIR facade.

I want to return OperationOutcome to the calling application when I detect an error.

My code at present is :

Need help where I can find email accounts which shows under AlertGroups dropdown?

We’re excited to announce the first mini hackathon “Building AI Agents with InterSystems”, taking place on a pre-conference day as part of InterSystems READY 2026.

In this hands-on challenge, participants will design and build AI agents using upcoming InterSystems capabilities, exploring how intelligent automation, orchestration, and reasoning can be applied to practical use cases.

📅 Event date: 27 April 2026
📍 Location: Gaylord National Resort & Convention Center, National Harbor, Maryland

Needs some help with FHIR return code 200 or 201 when processing HL7 messages in HealthConnect.

Issue:

1. If FHIR code is 200 or 201, HealthConnect keep processing HL7 messages

2. If FHIR code is NOT 200 or 201, HealthConnect keep suspend the HL7 messages in the messages queue, then keep processing NEXT subsequent HL7 messages in the TEXT file if the FHIR code is 200 or 201

Over the last 9 years, I published more than 90 packages in OEX.
And over this time, conditions and environments changed.
In the beginning, there was

• no Docker
• no IPM/ZPM
• no embedded Python, no AI
• Caché, Ensemble, CSP, ZEN, .... were dominating

As time changed, also product versions and external languages changed.
Adjustment of a few packages was no issue in the beginning,
and was a matter of support quality to my "consumers".

There are numerous excellent tools available for testing your REST APIs, especially when they are live. Postman, various web browser extensions, and even custom ObjectScript written with %Net.HttpRequest objects can get the job done. However, it is often difficult to test just the REST API without inadvertently involving the authentication scheme, the web application configuration, or even network connectivity. Those are a lot of hoops to jump through just to test the code within your dispatch class. The good news is that if we take our time to understand the inner workings of the %CSP.REST class, we will find an alternative option suited for testing only the contents of the dispatch class. We can set up the request and response objects to invoke the methods directly.

I have a Postgres table which should be migrated to IRIS. The table has a computed column, like:

CREATE TABLE example_table (
    id VARCHAR(10) PRIMARY KEY,
    normalized_id VARCHAR(10) GENERATED ALWAYS AS (LPAD(id, 10, '0')) STORED
);

IRIS also has the LPAD function but I can't figure out how to achieve the same result using pure SQL DDL.

Tried this:
