Hi Community,

We’re excited to invite you to take part in shaping the next generation of ObjectScript development tools. We’re working on an AI-powered ObjectScript coding assistant designed specifically for IRIS developers. Not a generic AI adapted for ObjectScript, but a solution built from the ground up to understand ObjectScript idioms, IRIS APIs, interoperability productions, and real-world developer workflows.

To make sure we build something truly useful, we need your input.

New AI CCR Assistant

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:

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?

I've modified the class file, but messages still arrive as a single line (e.g., "H|.../rQ|.../rL") instead of separate lines in the ASTM service. The <ENQ>..<EOT> header looks correct, logs show no errors, and the service receives messages fine. Is there an Ensemble 2018.1 engine setting (like line terminator handling or TCP framing) to fix the line splitting? ​

Hello everyone,

My team lead mentioned that users can sometimes create globals directly without associating them with tables or classes. In this case, these globals would not be accessible via SQL.

Is this correct? Can a global exist independently in this way, and if so, is there a specific approach to access or manage them without SQL?

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.

Who hasn't been developing a beautiful example using a Docker IRIS image and had the image generation process fail in the Dockerfile because the license under which the image was created doesn't contain certain privileges?

In my case, what I was deploying in Docker is a small application that uses the Vector data type. With the Community version, this isn't a problem because it already includes Vector Search and vector storage. However, when I changed the IRIS image to a conventional IRIS (the latest-cd), I found that when I built the image, including the classes it had generated, it returned this error:

    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
