Hi Community,

What is the correct syntax in a merge.cpf file to create a database with its associated resource ?

A .iostream file got stored in /intersystems/HCENG01B12/mgr/Temp for a BatchFileOperation class while HC was on the secondary node.  HealthConnect is now on the primay node and cannot find that .iostream file path.  The operation starts throwing errors when the RolloverSchedule is reached

OnKeepalive() returned ERROR #5012: File '/intersystems/HCENG01B12/mgr/Temp/QWhoZAwFF3f9jQ.iostream'
does not exist

How can I resolve this issue?

Hello InterSystems EHR community, 

InterSystems Certification is currently developing a certification exam for CCR Tier 2 users, and if you match the exam candidate description below, we would like you to beta test the exam! The exam will be available for beta testing starting January 27, 2026. 

Beta testing will be completed March 28, 2026.

What are my responsibilities as a beta tester?

where can use sandbox in InterSystems IRIS Data Platform 2025.3

CCR now includes an AI-powered 'CCR Assistant', available to beta testers. The CCR Assistant helps you quickly get answers about common CCR workflows, terminology, or best practices. Every response includes references to relevant ICC Training courses, making it easy to dive deeper into any topic. As a future improvement, the links will point directly to the specific page of the ICC Training PDF that was used to generate the response.

Currently in the health connect code, we are using Epic FHIR API Patient.Create, code return 200 or 201 status values, we process the message based on this return values.

Now I need to use Epic FHIR Patient.$match API, need to check FHIR Error code 4101 for this API. I looked for FHIR statndard return code, but this this seems not standard code, please advice how can I check 4101 value?

How many times have you had to receive or generate a JSON and wished you could work on it using DTLs without having to deal with DynamicObjects trying to remember the name of each field? Do you want to break down and make your giant JSON file more digestible?

In my case, never, but I thought that someone might find it useful to have a feature that captures your JSON and breaks it down into a series of ObjectScript classes that you can work with more easily and conveniently.

Well then...behold JSON2Class in all its glory!

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:

My code at present is :

Some concepts make perfect sense on paper, whereas others require you to get your hands dirty. Take driving, for example. You can memorize every component of the engine mechanics, but that does not mean you can actually drive.

You cannot truly grasp it until you are in the driver's seat, physically feeling the friction point of the clutch and the vibration of the road beneath. While some computing concepts are intuitive, Intelligent Agents are different. To understand them, you have to get in the driver's seat.

What is a FHIR Profile?

A FHIR profile is a collection of rules and constraints used to customize and refine a base Fast Healthcare Interoperability Resources (FHIR) resource. Profiling is a vital process that adapts the base FHIR resource standard to satisfy the unique requirements of a specific use case, geographic region, medical institution, or clinical workflow.

While the base FHIR specification provides generic, flexible definitions for resources (such as Patient, Observation, or Medication), profiles transform these generic resources into more precise ones. This ensures consistent and interoperable data exchange tailored for a particular community or implementation.

FHIR is designed to cover various healthcare scenarios globally. Profiles allow implementers to adapt this general platform without losing the benefits of standardization.

Hi folks!

Is there any way to know the text of the SQL queries executed against the IRIS server?

My case: I have an SQL class query with a few parameters and and some combination of values causes unexpected results.

It'd be great if I could just copy the query from some log of queries done vs my IRIS the server. Cannot find it easily, though. Any advice?

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

3. I am also using following "Reply Code Actions" in Operation settings (:?R=S,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C)

I like to install Cache Evaluation version for learning purpose. Could you please share the download link to install it? I appreciate any help you all provide. Thanks. 

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".

Details: 

RabbitMQ is a message broker that allows producers (those who send a data message) and consumers (those who receive a data message) to establish asynchronous, real-time, and high-performance massive data flows. RabbitMQ supports AMQP (Advanced Message Queuing Protocol), an open standard application layer protocol. 
The main reasons to employ RabbitMQ include the following:

• You can improve the performance of the applications using an asynchronous approach.
• It lets you decouple and reduce dependencies between services, microservices, and applications with the help of a data message mediator, meaning that there is no need for producers and consumers of exchanged data to know each other.
• It allows the long-running processing of sent data (with the results) to be delivered after utilizing a response queue.
• It helps you migrate from monolithic to microservices, where microservices exchange data via Rabbit in a decoupled and asynchronous way.
• It offers reliability and resilience by making it possible for messages to be stored and forwarded. A message can be delivered multiple times until it is processed.
• Message queueing is the key to scaling your application. As the workload increases, you will only have to add more workers to handle the queues faster.
• It works well with data streaming applications.
• It is beneficial for IoT applications.
• It is a must for Bots’ communication.
