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.

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:

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?

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? ​

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?

    Hi, I have simple email alert setup (EnsLib.EMail.AlertOperation) where in operations I have SMTP server setup and Recipients emails.

    Also I find Alert Groups dropdown option in operations, processes, how this is different from setting up simple email alert with recipients list?

    Please advise.

    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!

    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?
