#InterSystems IRIS

I have a stream that I read out until the end. I then append more content to the stream and want to read out only what has been added. How do I only read out the new contents of the stream? Essentially, I want to read a stream, record the end position, then once the stream is updated read the contents from that recorded position until at the new end. This stream needs to be kept intact for historical reference so cannot be cleared between reads.

For a long time I have wanted to learn the Django framework, but another more pressing project has always taken priority. Like many developers, I use python when it comes to machine learning, but when I first learned web programming PHP was still enjoying primacy, and so when it was time for me to pick up a new complicated framework for creating web applications to publish my machine learning work, I still turned to PHP.

Is a layer before the internal HTTP of Caché/IRIS, such as a Reverse Proxy or API Gateway, a good option?

Example: I have an API using %CSP.REST, and I am using the internal port for development. But for production and approval, I put a reverse proxy using NGINX. Is this recommended? Is it an alternative?

Hi Community,

I have created global with below values , now I want to iterate programatically.

^Book("Auto1","Properties","Color")="Red"
^Book("Auto1","Properties","Color1")="Yellow"
^Book("Auto1","Properties","Model")="SUV"
^Book("Auto2","Owner")="Prashanth"
^Book("Auto2","Properties","Color")="Green"
^Book("Color")="Red"
^Book("Color1")="Red"

i have used below method but only printing last2 elements properly

ClassMethod Iterate()
{
set subscript = ""
for {
set subscript = $order(^Book(subscript))
quit:(subscript = "")
write !, "subscript=", subscript, ", value=", ^Book(subscript)
}
}

Thanks,

Prashanth

We're planning to use Production Validator for validating our system upgrade (2016.2.3 to 2024.2) , and we are trying to understand what kind of benchmarking or performance metrics others have observed during similar efforts.

Specifically, we are looking for a case study or real-world example that includes details like:

• How many messages were validated?
• How long did it take to create the temporary database from the source system?
• How long did it take to run the comparison on the destination system?

You know that feeling when you get your blood test results and it all looks like Greek? That's the problem FHIRInsight is here to solve. It started with the idea that medical data shouldn't be scary or confusing – it should be something we can all use. Blood tests are incredibly common for checking our health, but let's be honest, understanding them is tough for most folks, and sometimes even for medical staff who don't specialize in lab work. FHIRInsight wants to make that whole process easier and the information more actionable.

Hello,

I am currently trying to install InterSystems IRIS for Health and specifically the Ensemble integration tool, but I am facing issues.

Here are the details of my setup:

• Version of IRIS: 2025.1 (Community Edition)
• Operating System: [Insert your OS here, e.g., Windows 10, Ubuntu 20.04, etc.]
• Issue: I have downloaded IRIS for Health, but I cannot find Ensemble during the installation process. I have tried using the Early Access programs, but Ensemble is not included in the options I can choose. I have also tried installing various versions of IRIS, but still, Ensemble is missing.

IRIS supports CCDA and FHIR transformations out-of-the-box, yet the ability to access and view those features requires considerable setup time and product knowledge. The IRIS Interop DevTools application was designed to bridge that gap, allowing implementers to immediately jump in and view the built-in transformation capabilities of the product.

Google Forms is the most popular solution on the market for collecting data, answering questionnaires and quizzes. So, it is the ideal solution for collecting patient data and responses in a practical way, without the need to expand or develop systems. In this article, I will detail how to create an account on Google Cloud, register the application that will consume the Google Forms API, generate the service user necessary to consume the API and finally perform actions to create new forms and collect data filled in them in an automated way in embedded Python and IRIS.

Profiling CCD Documents with LEAD North’s CCD Data Profiler
Ever opened a CCD and been greeted by a wall of tangled XML? You’re not alone. Despite being a core format for clinical data exchange, CCD's are notoriously dense, verbose, and unfriendly to the human eye. For developers and analysts trying to validate their structure or extract meaningful insights, navigating these documents can feel more like archaeology than engineering.

Hi all!

I want to create an %Embedding.Config to use with an %Embedding property. I followed the documentation for %Embedding.OpenAI, and it works fine after setting sslConfig, modelName, and apiKey.

However, I need to use AzureOpenAI. While the embedding process is similar to OpenAI's, Azure requires additional connection parameters, like an endpoint. My question is: is it possible to configure these extra parameters with %Embedding.Config, and if so, how?

Kong provides an open source configuration management tool (written in Go), called decK (which stands for declarative Kong)

• Check that decK recognizes your Kong Gateway installation via deck gateway ping

deck gateway ping   
Successfully connected to Kong!
Kong version:  3.4.3.11

• Export Kong Gateway configuration to a file named "kong.yaml" via deck gateway dump

deck gateway dump -o kong.yaml

• After modifying the IP adcresses in kong.yaml file, show the differences via deck gateway diff

deck gateway diff kong.

Hi community.

I was wondering if it was possible to use something like EnsLib.SQL.InboundAdapter with tables in IRIS.

This library monitors when a record has been inserted into a table in an external database, so it requires a DSN to connect to that database.

My goal is to make a call to an external API that takes a long time, it could spend nearly an hour (or more) completing its processes, but I don't want to block the main process.

My use case is I want AI to extract six pieces of key information from medical visit notes.

It works okay with notes from Epic patient portals. I am struggling with one of my own visit Summaries. So far I have not been able to instruct ollama to give me a JSON response where it gave me what I am asking for.

My original medical_progress_notes_prompt was:

Medical progress note:
---
(document)
---

You are an expert in analyzing medical progress notes.

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.

Hello everyone,

I’m using VS Code with the InterSystems ObjectScript extension and I want to keep my local folder (client-side) as the “source of truth” while still using the built-in Server Source Control features (diff, stage, commit, etc.) against my IRIS/Ensemble instance.

So far:

• I have a local Git repository with my .cls and .mac files.
• I’ve configured "objectscript.serverSourceControl.respectEditableStatus": true and "objectscript.serverSourceControl.disableOtherActionTriggers": false in my .vscode/settings.json.

I am trying to log in to the Web Gateway Management and I have missed placed the password to access the system I have tried 

changing the password under local settings in the CSP.ini  and that has managed to change the password to access the gateway but cannot log me into the management area I have followed a post here and read here and I seem not to get the answers that actual explain how I can get to the web gateway management.

We have a big update this quarter. 

• RHEL 10 was released yesterday, read on for what that means for you
• 2025.3 will use OpenSSL 3 across all operating systems  SUSE 15 sp6 will be the minimum OS for orgs using SUSE
• The minimum CPU standards are going up in 2025.3
• Older Windows Server operating systems will no longer be supported in 2025.3

I am struggling on how to pull out individual fields from a JSON. In a previous post someone had mentioned that I could...

  If ((tHttpResponseIsObject) && ($ZCONVERT(tHttpResponseContentType,"L") [ "application/json"))
  {
    set responseData = {}.%FromJSON(tHTTPResponse.Data)
    set pResponse = ##class(osuwmc.COM.Response.StringResponse).%New()
    if responseData.count =1{
      set pResponse.COMPortalURL = responseData.items.%Get(0).portalUrl
      set pResponse.COMPureID = responseData.items.%Get(0).pureId
      set pResponse.COMTitle = responseData.items.%Get(0).titles.%Get(0

What is the global ^Ens.AppData and is it secure kill it? These global is consuming many storage and need increase free space

Hi,

Those curious in exploring new GenerativeAI usecases.

Developers and analysts looking for a quick way to tame the Pattern Match operator.

In both ObjectScript and SQL this has a quite visually dense format.

 if booking?2A1"-"1(1"CARD",1"RAD")1.5N

SELECT DISTINCT PatientRef
FROM APPOINTMENT.BOOKING
WHERE Active='Y' AND
LocationCode %PATTERN '2A1"-"1(1"CARD",1"RAD")1.5N'

Challenge

Use generative AI to assist create and modify pattern match code from different natural language input.

Hi everyone,

It's me again😁. As usual I would like to share something I study recently, and today, I would like to share about the document DB😁.

1st of all, let's go to the documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GDOCDB_intro
Well, I must say, this one is much better to follow than the others, which I read before. 😭 Finally😭😭

Ok, let's start walking through it together

Here we go😀, we start a terminal from VSCode to connect to our IRIS

We are going to created Document DB demo.docpatient
 

1.

In Management Portal one can create and configure connection in:

System Administration
 > Configuration
  > Connectivity
   > SQL Gateway Connections
    > Create New Connection

But how to create new connection programmatically?

I am testing vectorsearch, while doing so I am trying to paginate my resultset for a "next page" function to give me the first, second, third 15 entries within a table. 

For this I have two embedding classes. One with a HNSW Index (vectornomicembedtextlatest), and one without (vectornomicembedtexttest).

Calling SELECT ID,PRIMKEY FROM SQLUser.vectornomicembedtexttest LIMIT 5 OFFSET 1 works fine with the first entry having the rowID of 486448. (I deleted old entries in the beginning and reused the table)

SELECT ID,PRIMKEY FROM SQLUser.

hey everyone,

we are new to InterSystems health share, we are running health connect in a cluster with primary, backup and dr nodes.

we kept noticing that web applications definitions aren't showing in the backup or dr node.

is that normail? would they show up after failover to backup node or cutover to dr node?

thanks

Hi,

How do I create CSP page in IIS to be loaded from the class? 

Im able to open my index.html but I have class webapp.init.cls which extends %CSP.Page which should generate html. If I write localhost/myapp/webapp.init.cls I just got an error Invalid action.

In IIS Handler Mappings I did setup for *.cls and *.csp files. 

I followed this

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

When I created index.csp my IIS just return NOT FOUND. With the old APACHE server I had no issue with all, but Im trying to migrate to IIS.
