You have probably heard a lot about LLMs (Large Language Models) and the associated development of RAG (Retrieval Augmented Generation) applications over the last year. Well, in this series of articles we will explain the fundamentals of each term used and see how to develop a simple RAG application.

What is an LLM?

LLM models are part of what we know as generative AI and their foundation is the vectorization of huge amounts of texts.

Hi Community,

Visual Studio Code releases new updates every month with new features and bug fixes, and the September 2024 release is now available. 

Version 1.94 now includes: 

• Find in Explorer - Quickly find files in the Explorer view with the improved Find control. As a consequence of this, the Explorer's Find widget on server-side folders requires v2.12.9-beta.4 or later with Proposed APIs enabled. Read more in this Developer Community post. 
• Source Control Graph - More filtering options and interactivity in the Source Control Graph.

It has been asked a few times recently, how one can make Laravel Framework work with InterSystems IRIS Data Platform. It's been a while since this post about Laravel and InterSystems Caché was published. To bring it up to date, the article gives a brief instruction set on how to setup and configure a Laravel project for use with InterSystems IRIS through ODBC.

What is Laravel?

Laravel is a PHP framework that is based on MVC architecture. Using Laravel simplifies and speeds up the backend development while building modern secure web applications.

I am working on a scenario where source will be sending 6 files to HealthConnect. In HealthConnect we need to process all the 6 files and send them to MoveIT through the Operation. In Health Connect we need to configure a property file through the data that we will be receiving in one for the six files.
Can someone help me with the workflow that can be setup to achieve this.

Hi all,

Does anyone know of a way for a business host (specifically an operation) to check whether the production it's running in is trying to shut down?

Cheers,

Good morning, everyone

I purchased an HP LaserJet M101-M106 printer, and I'm trying to print via the Windows cache device, but I can't get it to work.
I can send it, but it doesn't print.
Physical device name: |PRN|HP LaserJet M101-M106
Type: Other
Subtype: P-DEC
Open Parameters: “W”

Could someone help me with what might be happening?

Otherwise, thanks

Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in September 2024:

I have three different methods for exporting classes and projects as XML files, but each one produces slightly different output:

1. Studio (what I currently use for exporting): I export as a project (with the 'only project' option disabled). This generates all classes and the project in a single XML file.
2. VS Code: This method only exports the classes, and it doesn't include the project in the XML file.
3. Console export using %SYSTEM.OBJ.Export: I used the following command to attempt the same export as Studio: do ##class(%SYSTEM.OBJ).Export("MyProject.Prj, MyProject.*.cls", "TempDir/MyProject.

If one of your packages on OEX receives a review you get notified by OEX only of YOUR own package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you made a major change and expect a changed review just let me know.

Hi all,

When passing on the content of a file in a REST API call, I need to put the original file name in an HTTP header. As it happens, some file names have non-8-bit characters in them ("å", "ö", and the like), and these arrive garbled on the other side. Does anybody know the correct way to encode them (assuming they should be encoded at all)?
$zconvert(filename, "O", "UTF8") does not appear to be it. I'm leaning towards $zconvert(filename, "O", "URL"), but leaning isn't good enough.
Thanks,
Otto

I try to add custom setting in BPL process by adding parameter SETTINGS = "Scope" and property Scope As %String. But how do I access instance property in BPL process? I get error that method or property Scope is not found.

Hi Community,

A new GenAI-supported tool is coming to the online documentation and learning sites! What will it be called?

Take a 5-minute survey and share your reactions to possible names!

We've recently made available a new version of InterSystems IRIS in the Vector Search Early Access Program, featuring a new Approximate Nearest Neighbor index based upon the Hierarchical Navigable Small World (HNSW) indexing algorithm. This addition allows for highly efficient, approximate nearest-neighbor searches over large vector datasets, dramatically improving query performance and scalability.

Hi all,

I'm wondering if it is possible to call a Business Operation from other Business Operation.

I have a BO that writes logs into a database, using a personal message. I can create a set obj=##class(MyLogs).%New() but the BO has all parameters about connection.

Is it possible?

Best regards.

Hi folks!

Often, when we develop commercial solutions, there is a necessity to deploy solutions without source code, e.g., in order to preserve the IP.

One of the ways how this can be achieved is to use InterSystems Package Manager.

Here I asked Midjourney to paint an intellectual property of software:

How this can be achieved with IPM?

In fact, this is very simple; just add the Deploy="true" clause in the Resource element in your module.xml manifest. Documentation.

I decided to provide the simplest possible example to illustrate how it works and also to give you a development environment template to let start building and deploying your own modules without source code. He we go!

Hi,

I try to create a tab delimiter file with bold header, when I convert the file into Microsoft Excel, it has a bold header.  The file can be in text or CSV exension.

Thank you.

We have Webterminal around for quite a while, but it was limited, not all features worked there. There was no shell support or the latest feature as embedded Python support. There are some issues with tools that require programmer mode. Basic Authorization, not as handy as simple login page, where you could have options to add own login page, in case if you would wish to change the way how to login to the application, such as using SSO.

With the original iris terminal, wrapped into a web form, using most used in the web world xterm.js, used in tools like VSCode as well, with some magic from Python, which helped with interprocess tty. We can get the the terminal in the web, in the full capacity.

There are many applications for working with HL7 V2 messages, but the tools for working with XML in IRIS Management Portal and Cache Studio are limited. While plenty of external utilities and IDEs work with XML messages and even C-CDA documents, there is a compelling case for being able to test directly against the IRIS C-CDA framework. 

Testing within the IRIS environment provides the necessary context: 

• XML parser configuration
• XML namespace context
• Facility and OID setup
• IHE header handling
• The HS.IHE.Util, HS.Util.XSLTTransformer, and %XML.XSLT.

Hello,
Can I receive a 30 day full test license?

If several application servers are connected using ECP, and one of them create many locks, so many that lock table became full :

Should we expect only that application server to be impacted ? (usually, when lock table is full the system became instable). Or, are other application servers going to be impacted the same way ? (because that lock table is synchronized and maintained in sync across all servers)

I have another question (which is related) : is this the same with remote databases ?

Hi Community, 

We’ve missed Global Masters, and we’re sure you have too!

🚀 Global Masters is Relaunching on October 3, 2024!

On 2024-08-29, the team released Language Server v2.6.0, which includes more improvements for code completion (aka intellisense). That means that #dim, while still useful, is hardly necessary anymore. That's a good thing in my opinion.

This post from last year (Intellisense and code completion in VS code objectscript) talked about using #dim for code completion for OREFs. #dim has always been useful for both Studio and VS Code. But last year, VS Code ObjectScript was slightly behind Studio in this area, and #dim helped bridge that gap. But now, VS Code has surpassed Studio.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

This is for IRIS For Health 2024.2.0

We are migrating away from the .NET Gateway and trying to use the python integration instead.

I followed the instructions to install IRIS

Then I installed python following the IRIS documentation indicating that python should be installed globally.

I set up the PythonRuntimeLibrary and PythonRuntimeLibraryVersion options under System->Configuration->Advanced memory settings and when I run the shell function, I get python:

USER>do ##class(%SYS.Python).Shell()
