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? ​

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:

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.

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.

    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

    An Overview of Database Degrade

    Introduction

    Hello! In this article, I will be discussing database degrade, a type of data integrity issue one can face when using IRIS. First, I will be going over a review of the structure of IRIS databases. I'll then discuss how database degrade can manifest and common causes of degrade issues. I'll then conclude with general tips we give our customers about how to prevent or prepare for database degrade issues.

    Archiving my OEX packages

    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".

    Why do these clauses affect SQL performance?

    select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite
    select top 10 ID from some_table where row_status in ('I','U') order by ID - the same
    select ID from some_table where row_status in ('I','U') order by ID - is fast

    Actually there are no rows in the table having row_status 'I' or 'U'.

    I asked Gemini and it recommended me rewrite the query as

    Here at InterSystems, we often deal with massive datasets of structured data. It’s not uncommon to see customers with tables spanning >100 fields and >1 billion rows, each table totaling hundred of GB of data. Now imagine joining two or three of these tables together, with a schema that wasn’t optimized for this specific use case. Just for fun, let’s say you have 10 years worth of EMR data from 20 different hospitals across your state, and you’ve been tasked with finding….

    As applications grow, every database eventually hits scaling limits. Whether it's storage capacity, concurrent users, query throughput, or I/O bandwidth, single-server architectures have inherent constraints. This guide explains fundamental approaches to database scalability and shows how InterSystems IRIS implements these patterns to support enterprise-scale workloads.

    We'll explore two complementary scaling strategies: horizontal scaling for user volume (distributing computational load) and sharding for data volume (partitioning datasets). Understanding the general principles behind these approaches will help you make informed decisions about when and how to scale your IRIS applications.

    The examples in this guide use InterSystems IRIS in Docker containers.

    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.

    There are numerous excellent tools available for testing your REST APIs, especially when they are live. Postman, various web browser extensions, and even custom ObjectScript written with %Net.HttpRequest objects can get the job done. However, it is often difficult to test just the REST API without inadvertently involving the authentication scheme, the web application configuration, or even network connectivity. Those are a lot of hoops to jump through just to test the code within your dispatch class. The good news is that if we take our time to understand the inner workings of the %CSP.REST class, we will find an alternative option suited for testing only the contents of the dispatch class. We can set up the request and response objects to invoke the methods directly.

    Minimum IRIS container footprint

    Sometimes customers need a small IRIS instance to do something in the cloud and shut it down, or they need hundreds of containers (i.e. one per end user or one per interface) with small workloads. This exercise came about to see how small an IRIS instance could be. For this exercise we focused on what is the smallest amount of memory we can configure for an IRIS instance. Do you know all the parameters that affect the memory allocated by IRIS ?

    What is JWT?

    JWT (JSON Web Token) is an open standard (RFC 7519) that offers a lightweight, compact, and self-contained method for securely transmitting information between two parties. It is commonly used in web applications for authentication, authorization, and information exchange.

    A JWT is typically composed of three parts:

    1. JOSE (JSON Object Signing and Encryption) Header
    2. Payload
    3. Signature
