The "Ask Developer Community AI" tool is an excellent resource for studying for the certification. I asked it about each topic that will be covered in the test and the results are below.
Note: I classified each answer by the assertiveness that I consider as good, average and bad.

Note 2: The article has 4 parts, each one for an exam area.

Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.

We are starting to see this error message...

ERROR <Ens>ErrBPTerminated: Terminating BP DocOutRptRouting3M360 # due to error: ERROR <Ens>ErrException: <INVALID OREF>zOutputToIOStream+6^EnsLib.HL7.Message.1 -- logged as '-' number - @''
> ERROR <Ens>ErrException: <INVALID OREF>zOutputToIOStream+6^EnsLib.

Hi, Community!

Hello and welcome to the Developer Ecosystem News!

The first quarter of the year was full of exciting activities in the InterSystems Developer Ecosystem. In case you missed something, we've prepared a selection of the hottest news and topics for you to catch up on!

Background:

This guideline provides an overview of how to design and implement a REST API interface for querying patient demographic data from an Electronic Patient Record (EPR) system using HealthConnect. The process involves sending a query request with the patient's identification number, retrieving the response from the EPR system, extracting the required patient demographic data from the HL7 message, and sending it as a JSON response to the supplier. The high-level process diagram is shown below (Screenshot 1).

Hi Community,
In this article, I will introduce my application iris-AgenticAI .

The rise of agentic AI marks a transformative leap in how artificial intelligence interacts with the world—moving beyond static responses to dynamic, goal-driven problem-solving. Powered by OpenAI’s Agentic SDK , The OpenAI Agents SDK enables you to build agentic AI apps in a lightweight, easy-to-use package with very few abstractions. It's a production-ready upgrade of our previous experimentation for agents, Swarm.
This application showcases the next generation of autonomous AI systems capable of reasoning, collaborating, and executing complex tasks with human-like adaptability.

Application Features

• Agent Loop 🔄 A built-in loop that autonomously manages tool execution, sends results back to the LLM, and iterates until task completion.
• Python-First 🐍 Leverage native Python syntax (decorators, generators, etc.) to orchestrate and chain agents without external DSLs.
• Handoffs 🤝 Seamlessly coordinate multi-agent workflows by delegating tasks between specialized agents.
• Function Tools ⚒️ Decorate any Python function with @tool to instantly integrate it into the agent’s toolkit.
• Vector Search (RAG) 🧠 Native integration of vector store (IRIS) for RAG retrieval.
• Tracing 🔍 Built-in tracing to visualize, debug, and monitor agent workflows in real time (think LangSmith alternatives).
• MCP Servers 🌐 Support for Model Context Protocol (MCP) via stdio and HTTP, enabling cross-process agent communication.
• Chainlit UI 🖥️ Integrated Chainlit framework for building interactive chat interfaces with minimal code.
• Stateful Memory 🧠 Preserve chat history, context, and agent state across sessions for continuity and long-running tasks.

Hi Guys,

Not sure what I'm missing here, I'm using to download files that starts with MTC_88 from S3 bucket using AmazonS3 inboundAdapter as below, but I'm not getting anything and I'm sure there thousands of files that starts with MTC_88 

and the log is not getting any errors?

Thanks

 JSON Web Token (JWT) Authentication

Hi Everyone,

I would like to share the code and step-by-step instructions/or guideline for generating a JWT (JSON Web Token) signature, as well as how to test it using Postman / HealthConnect.

JWT is an open standard (RFC 7519) that defines a compact, URL-safe method for securely transmitting information between parties in the form of a JSON object.

Structure of a JWT:

A JWT consists of three parts, separated by dots (.):

Hi all,

As part of the development an API to know what is the instance of IRIS is connected, I've found some methods to know information about the server that can help you.

Get the server name: $SYSTEM.INetInfo.LocalHostName()

Get the server IP: $SYSTEM.INetInfo.HostNameToAddr($SYSTEM.INetInfo.LocalHostName())

Get the instance name: $PIECE($SYSTEM,":",2)

So, I have created the following code as BS class:

Class St.Common.Api Extends (%CSP.REST, Ens.BusinessService)
{
{

XData UrlMap [ XMLNamespace = "http://www.intersystems.

When batch inserting data into a table via SQL, I can use the %NOCHECK keyword to avoid checking foreign key integrity.  This would be appropriate for cases when the inserted data has been verified by some external process.

However, when inserting via objects, I don't see a way to get the same behavior.  Are there any workarounds that use objects for this?

For this case, I have a tool (Tier 2 CCR) for loading many objects into a namespace. The referential integrity of these objects has already be confirmed in a source namespace.

I just realized I never finished this serie of articles!

In today's article, we'll take a look at the production process that extracts the ICD-10 diagnoses most similar to our text, so we can select the most appropriate option from our frontend.

Looking for diagnostic similarities:

From the screen that shows the diagnostic requests received in HL7 in our application, we can search for the ICD-10 diagnoses closest to the text entered by the professional.

To speed up the search process, we stored the vectorized text of the diagnosis received at the time of capturing the HL7 message in our database.

Hi,

I've a list of running scheduled task in task manger and would to crate a tasks to monitor if any of my tasks has stopped running, is there a function to check tasks status?  

Thanks 

Prompt

Firstly, we need to understand what prompt words are and what their functions are.

Prompt Engineering

Hint word engineering is a method specifically designed for optimizing language models.
Its goal is to guide these models to generate more accurate and targeted output text by designing and adjusting the input prompt words.

Is there a File Service (or a way to define a RecordMap) to intake a file that contains records that are JSON object?I would like to have my Service route each record(object) to a Process one at a time.

Hi Community!

I'm very excited to share with you some highlights from yesterday, from UK&I Data Summit in Birmingham! There are exciting announcements, FREE tickets to the Summit and much more, so read on!

how can I get the classMethod name ?
like we get class name using "$CLASSNAME($THIS)", same way I need class Method ?

Now it is possible ask your IRIS server using an AI Chat or compose other agent applications to get:

1. List the server metrics
2. Return intersystems iris server information
3. Save the global value Hello to the global name Greetings
4. Get the global value Greetings
5. Kill the global Greetings
6. List the classes on IRIS Server
7. Where is intersystems iris installed?
8. Return namespace information from the USER
9. List the CSP Applications
10. List the server files on namespace USER
11. List the jobs on namespace %SYS

To do it, get and install the new package langchain-iris-tool (https://openexchange.

I'd like to ask you for recommendations on how to properly use repository dependencies when using VSCode and Client-side editing. Suppose I have projects A, B and C, with A being independent, B depending on A, and C depending on A and B. I am currently working with the main project C, and I want to be able to contribute to all the other projects in a single VSCode window (instead of opening three instances). How do you solve this problem? Git submodules? ZPM? Something else?
