Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2Guide

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

How do you iterate over the array of namespaces returned in the result byref from the call below?

DO ##class(%SYS.Namespace).ListAll(.result)

Running "zw result" displays the namespaces (as individual subscripts in result) in the Terminal but I want to be able to programmatically iterate through each namespace name.

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Hi!

I'm trying to set up a Clinical Viewer demo env with HealthShare 2024.2.
I've done the standard installation following the doc :

Is there a simple way to compare Stream data between two objects?

We have used $ZCRC to create a checksum and that seems to be work.

We have also read each line of the streams and compared them and that seems to work too.

We just think there has to be a simpler way than looping through all the lines of the stream.

Any suggestions would be appreciated.

In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

Hi community members!

I'm testing some functionalities about Foreign Tables and it works smoothly with PostgreSQL database, but I found out an issue with MySQL database, I followed the documentation:

I am trying to log certain program data in my ObjectScript REST class, to track down a bug I have. I am comparing two values at runtime, and one result does one thing, and another a different thing. Since this is a REST API class, I have no way of seeing in real time what the value is to debug. I cannot simply run the method in debug in Studio as it will not run properly being a REST class method, nor have the correct incoming header data to correctly replicate what is happening in the API at runtime when being hit by client apps.

Hi Community,

Traditional keyword-based search struggles with nuanced, domain-specific queries. Vector search, however, leverages semantic understanding, enabling AI agents to retrieve and generate responses based on context—not just keywords.

This article provides a step-by-step guide to creating an Agentic AI RAG (Retrieval-Augmented Generation) application.

Implementation Steps:

1. Create Agent Tools
   • Add Ingest functionality: Automatically ingests and index documents (e.g., InterSystems IRIS 2025.1 Release Notes).
   • Implement Vector Search Functionality
2. Create Vector Search Agent
3. Handoff to Triage (Main Agent)
4. Run The Agent

Hi, Community!

We're happy to introduce a new learning path created by the Online Learning team:

Getting Started with InterSystems ObjectScript

Are there any objectscript functions (not wizards) to export and then import table data (including RowID)?

It doesn't matter what format the exported file is.

The import and export process should preserve all relationships, foreign keys, etc. I need to be able to export and import multiple tables at the same time.

I need this to implement the ability to export multiple tables from one instance and load them into another.
