Hello,

With my team, we're evaluating the different streams existing in order to find good pratices for our project using InterSystems IRIS. In doing so, we found that there exists different forms of the same stream with the %Stream.FileBinary and %Stream.FileBinaryGzip classes. We think that the %Stream.FileBinaryGzip takes less space to be stored, but is there other diferences between these two classes and what would you recomend to use ? Is it the same thing for %Stream.FileCharacter and %Stream.FileCharacterGzip ?

Thanks for your help,

Hi Guys,

My Cache.dat has a expanded a lot and some globals occupy a lot of disc space with just junk data so I would like to kill some globals and shrink the cache.dat file because I'm running out of disk space?
So is there a way to do that without having to do it through the Truncate & Compact databases?

Thanks

Hey everyone.

I was curious if anyone had any success/tips with regards to using a global or a system parameter/property to control the behavior of a transform or process/operation.

Is there a parameter I can currently reference from the system that can be used for an if/else, or am I best off creating a simple Global and setting it according to the environment I am in?

I'm new to Cache and trying to follow the Using Cache Studio PDF. In section 2.4.3(Adding a Zen form) it tells you insert the following code;

<button caption="Save" o select="zenPage.saveRecord();" />

Unfortunately that code fails compilation. If you try and use the tools there is no o select option nor a select or onselect option. I was wondering if anyone has used this PDF before and knows what the correct attribute should be?

Hello all,

I'm trying to build a cube based on a linked table but seems that IRIS is not able to do it :O

Long story short, I have a linked table in IRIS that sources a Microsoft SQL table (using standard linked feature from the portal). It works fine, I can access it using SQL as many other times. On top of that, I've created in DeepSee (ok, Analytics) a cube that uses this class as source. It compiles correctly, no errors given. When I build it with 100 records, all goes well and using Analyzer I can see results.

Template engines are essential for producing customizable dynamic content, without the need for compilation and opening up great possibilities of extensibility for the template user. Especially if the template engine supports Python. A popular solution for template engine is Mko. It is is a template library written in Python. It provides a familiar, non-XML syntax which compiles into Python modules for maximum performance. Mako's syntax and API borrows from the best ideas of many others, including Django and Jinja2 templates, Cheetah, Myghty, and Genshi.

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

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

Hi All! If you have looked into Health Connect Cloud at all, you may know that the cloud-native environment presents a few differences from traditional deployments of InterSystems integrations. If you've taken a classroom course at InterSystems, you may have used "in" and "out" folders in productions to simulate receiving and outputting HL7 messages.

EN Interopway XDBC

Hey guys!!!

I finally got some time to organize a set of classes that I've been using for a few years to make it easier and kill the repetitive work of developing intragrations using XDBC.

Access the project repository at https://github.com/cristianojs/interopway

I've already registered on the Open Exchange. I'm wait for approval.

The idea is to increase the project with more components, I already have one that the "dough is rising and is already going to the oven".

Any questions post here.
