Using IRIS as a vector database

InterSystems IRIS embedded vector search capabilities lets us search unstructured and semi-structured data. Data is converted to vectors (also called ‘embeddings’) and then stored and indexed in InterSystems IRIS for semantic search, retrieval-augmented generation (RAG), text analysis, recommendation engines, and other use cases.

This is a simple demo of IRIS being used as a vector database and similarity search on IRIS.

InterSystems API Manager (IAM) is a core component of the InterSystems IRIS Data Platform, offering centralized API management with a strong emphasis on security. IAM simplifies the entire API lifecycle, from creation to retirement, and provides a developer portal for easy API discovery and integration. Access control features allow administrators to define precise permissions, and IAM seamlessly integrates with the IRIS Data Platform, enhancing data management and integration capabilities.

Features of IAM include:

"The Hidden HTTP Errors" (Behind IIS)

You send an HTTP request and get back an HTTP error but with an HTML error page which you didn't expect... what's happening?... 🤔

Specifically for example, perhaps you tried to READ a FHIR Resource (e.g. /Patient/123) and you get back a 404 error page, even though with other Patient IDs, you get back the Resource payload, so "the page" definitely does exist... why should you be getting a 404 error page? 🙄

XDBC memory leaks

I have a business service that actively reads data from a remote Postgres database. OnProcessInput opens a XDBC (actually JDBC) connection, executes an SQL query, fetches several thousand rows, iterates the resultset, and closes the connection. On each iteration I also need to update each source row in the remote database using PreparedStatement.

In other words, in every OnProcessInput call I have a long running SELECT statement and several thousands small UPDATE statements.

The problems I'm facing are:

Code Golf: Binary encoding!

Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

  • First Step: Reverse Cipher

    • Reverse the entire input string.
    • Relocate the last character of the original string (now the first character of the reversed string) to the end.

  • Second Step: Alphabetic Index Binary Encoding

The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.

Looking at my database I see I have a very big ^rINDEXSQL global? Why is that? 😬

In the Management Portal SQL page, under "SQL Statements" I see a 'Clean stale' button - what does this do? 🤔

In the list of Statements some have a 'Location' value and some don't? How is that? 🤨

We have created a CSP application in the path /csp/ourapp. Due to some session handling issues, we created a new web application /csp/ourapp/hl7mapping that points to the sane namespace, and we now access the CSP pages using this new URL. This works fine in the local system.

After deploying the app to server, we are facing issues around compiling CSP pages.

Project Overview / Introduction

Developing and testing REST APIs in InterSystems IRIS often requires a significant amount of boilerplate code. While ObjectScript provides powerful tools for building APIs, writing consistent and repeatable tests can be time‑consuming. This is where IrisOASTestGen comes in.

In this article, we will discuss all the debugging tools included in the Microsoft Visual Studio Code IDE.

What will be covered:

  • Breakpoints
  • Watch window
  • Call Stack

Let's start by learning about debugging requirements!

Prerequisites

There are two plugins (extensions) for debugging ObjectScript:

The first is part of the InterSystems ObjectScript Extension Pack. The second is Serenji, a standalone plugin that provides an editor, file manager, and debugging functionality. Both plugins can be installed from the plugin store. To activate key functionality, Serenji requires a license. For this article, we'll use the InterSystems ObjectScript Extension Pack to reduce the learning curve. After you've mastered the basics, you can consider purchasing a paid license for Serenji.

I am experimenting with OpenTelemetry and recently connected all IRIS instances to telemetry servers.
I'm not interested in emitting custom metrics since IRIS does it fine, regarding tracing - we can use %Trace classes to emit custom traces, but what about logging?

I see that IRIS is able to send system log messages to the OpenTelemetry servers:

Hi everyone.

I'm going to give you a quick tip on how to implement an AI agent to search the Intersystems documentation integrated into Teams.

Yes, I know the documentation page has its own AI search engine and it's quite effective, but this way we'd have faster access, especially if Teams is your company's corporate tool.

You can also create another AI agent to search articles published in the developer community (which also has its own integrated AI search engine).

I want to extract data from IRIS (Health Share Provider Directory) and write the data out to a file that I can use within an external system. Using EnsLib.SQL.Service.GenericService do I need to supply Credentials if I am querying IRIS locally? I have always used JDBC to connect externally when creating Services and Operations to read/write SQL data from external Databases, but never internally. Normally I would just use sql or code to pull the data within a Process or DTC. But in this case, I want the Service to drive the workflow, and query the data from Local Tables

Hello everyone.

I have a question regarding the priority when applying a default configuration.

I have several Business Services that use the same class, so I want them all to have a common "Schedule" configuration.

However, there's one that I don't want this default configuration applied to, so I've tried setting the Schedule value to empty for that element based on its name:

In this case, the elements that use the class Kurro.BS.SFTP.Marca have the default value "CargaFicheros".

Introduction.

In this article, we'll cover a quick start to Git development with the InterSystems Developer Community and version control practices when working with IRIS InterSystems. We'll cover scenarios where we need to export Interoperability classes, globals, and analytics elements such as cubes and dashboards. These scenarios encompass key version control practices with IRIS.

To get started, you'll need:

  1. Register and log in to GitHub
  2. Be a member of the intersystems-community organization on Git

Getting started with IRIS InterSystems is very simple!

For the question in the Title, the AI Chat gave a response of:


The ‘Current Users’ value displayed by the $System.License.ShowSummary() method represents
real-time license usage tracked in shared memory on the local system.

We are trying to reconcile which user/process are associated with the counts that are returned.

Does anyone know how to get the detail of 'license usage tracked in shared memory on the local system.'?

Thanks you for your time.

- Patrick
