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.

Prerequisites:

1. Python
2. InterSystems IRIS for Health - as it will be used as the vector database

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? 🙄

Hello!!!

Data migration often sounds like a simple "move data from A to B task" until you actually do it. In reality, it is a complex process that blends planning, validation, testing, and technical precision.

Over several projects where I handled data migration into a HIS which runs on IRIS (TrakCare), I realized that success comes from a mix of discipline and automation.

Here are a few points which I want to highlight.

1. Start with a Defined Data Format.

Before you even open your first file, make sure everyone, especially data providers, clearly understands the exact data format you expect. Defining templates early avoids unnecessary bank-and-forth and rework later. 

While Excel or CSV formats are common, I personally feel using a tab-delimited text file (.txt) for data upload is best. It's lightweight, consistent, and avoids issues with commas inside text fields. 

PatID   DOB Gender  AdmDate
10001   2000-01-02  M   2025-10-01
10002   1998-01-05  F   2025-10-05
10005   1980-08-23  M   2025-10-15

Make sure that the date formats given in the file is correct and constant throughout the file because all these files are usually converted from an Excel file and an Basic excel user might make mistakes while giving you the date formats wrong. Wrong date formats can irritate you while converting into horolog.

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.

Now, consider this query:

If the Age column does not have an index, the database engine will:

• Check if the WHERE condition field has an index.
• If not, it will scan the entire table (a full table scan).
• The Power of Indexing in Database TablesWhen working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval.Check if the WHERE condition field has an index.If not, it will scan the entire table (a full table scan).

Also in previous versions you could define your FHIR Server to accept requests via OAuth 2.0 (e.g. for a SMART on FHIR client) but nowadays with v2024.3, which was released a while ago, there is a new feature, that enables doing this more easily - the OAuth FHIR Client QuickStart.

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.

We noticed that following compilation command works for CSP files located under the physical path /csp/ourapp, but it does not compile the CSP files placed under /CSP/ourapp/hl7mapping.

do $SYSTEM.CSP.LoadPageDir("/CSP/ourapp/","ck")

Hello Community,

What is the correct way to import and compile .dfi files when using zpm load? Do .dfi files need to be defined in module.xml?

I have code that imports the .dfi file successfully; however, when I run
zpm "load /home/irisowner/dev/ -v"

I get the message: Unknown file type. Skipping file: .pivot.DFI

While ObjectScript provides powerful tools for building APIs, writing consistent and repeatable tests can be time‑consuming. This is where IrisOASTestGen comes in.IrisOASTestGen is a utility designed to generate the structure of test classes and the supporting utility code directly from an OpenAPI 2.0 specification.

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.

As part of our 10-year celebration, we are pleased to recognize certain members whose long-standing contributions have significantly shaped the InterSystems Developer Community.

Over the past decade, these individuals have shared knowledge, supported peers, and helped strengthen the collaborative spirit that defines our Community.

Monitoring your IRIS deployment is crucial. With the deprecation of System Alert and Monitoring (SAM), a modern, scalable solution is necessary for real-time insights, early issue detection, and operational efficiency. This guide covers setting up Prometheus and Grafana in Kubernetes to monitor InterSystems IRIS effectively. 

This guide assumes you already have an IRIS cluster deployed using the InterSystems Kubernetes Operator (IKO), which simplifies deployment, integration and mangement.

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:

{
  "when": "2025-12-10 10:46:25.185",
  "pid": "11852",
  "level": "SEVERE",
  "event": "Generic.Event",
  "text": "ISCLOG: CSPServer  Error displaying login page $ZE= ns=TEST rtn=%SYS.cspServer ...(repeated 2 times)"
}

When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.

When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.These days, tokens signify security. JSON Web Token (JWT) Authentication has become one of the most popular standards for securing REST APIs. Fortunately for IRIS users, we have a straightforward way to set up applications to be protected this way. Yet, the idea is still similar to my old arcade days.

InterSystems FAQ rubric

If you try to kill a global that is mapped at the subscript level from the top node, you will get a <SLMSPAN> error and it will not be deleted. This is because the kill command for subscript-level mapped globals cannot be used across mappings.

// Suppose subscript-mapped globals exist in different databases, as shown below:^TEST(A*～K*) -> database A
^TEST(L*～Z*) -> database B

// Trying to kill from the top level will result in a <SLMSPAN> error.
NAMESPACE>Kill^TEST
<SLMSPAN> <- This error is output.

An extension “extends” or enhances a FHIR resource or a data element in a custom way. The extension can be added to the root of a resource, such as “Patient.ethnicity” in US Core profile, and they can be added to individual elements such as HumanName, Address or Identifier.

Did you know that you can also add an extension to a primitive data type?

Primitives usually store a single item and are the most basic element in FHIR. For example: "Keren", false, 1234, 12/08/2024 etc.

For example, the patient resources might look like this:

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).

Hello all,

First time post and newer to Cache/ObjectScript in general, please keep it in mind! 

Hello all,First time post and newer to Cache/ObjectScript in general, please keep it in mind! Some background: I need to build part of a production whose goal is to send patients emails based on appointment status as a daemon-based approach. I have to use Microsoft Graph to accomplish this, which you need an access token to use. To get the access token, I have to go through the OAuth2.0 client credentials grant flow, which involves the creation of a signed JWT assertion using the RS256 algorithm.  I was looking at the %OAuth2.JWT class to accomplish this, via its ObjectToJWT() method.

Hi,

We’re launching an Early Access Program for an upcoming Table Partitioning feature that will help IRIS customers manage very large tables, and distribute row data and associated indices across databases and storage tiers. Table Partitioning cuts deep into the core of IRIS relational data management, so we want to make sure we get things right through working with a few engaged customers who can provide feedback on the initial deliverables, and fine-tune as needed.

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

Using a Workflow Task within HealthShare Provider Directory, when a user clicks on Resubmit message within my Business Process, I check the status of the response. If the response is "Resend Message", I have my Business Process executing the following...

set tSC = ##class(Ens.MessageHeader).ResendDuplicatedMessage(context.SessionID)
 if$$$ISERR(tSC) $$$LOGSTATUS(tSC)

the context.SessionID is the Session ID of the message as it is being pass thru the Business Process. Does anyone see why that would not work off hand?

I am getting the following error periodically:

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".
