Hi Developers!

Sometimes we need to deal with classes/tables where the primary key and the IdKey are something that is maintained by yourself.

What is the proper way to generate a new ID in case where ID is a %BigInt?

Property id As %Library.BigInt

Are there any system methods to provide it?

There is data already imported via SQL, so there is no last ID stored in ^myclassD, so I cannot do $I(^myclassD).

Thinking of:

set newid=$O(^myclassD(""),-1),newid=$I(newid)

What do you think?

Hello community!
I have a small challenge for you :)

One of customers is sending quite a lot of messages between interoperability components, which mix standard request content and streams representing serialized JSON objects. As these JSON streams can be quite long (but not too long, just couple hundreds of characters) they would appreciate if the JSON content of stream was displayed in a nice-to-read way, using syntax highlighting by message trace view.

This picture illustrates the challenge - we are talking about the text framed by a red rectangle:
 I'd love to hear from anyone that you we

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

  • For each alphabetic character, determine its zero-based index in the lowercase alphabet (a-z).
  • Replace odd-indexed characters with '1' and even-indexed characters with '0'.
  • Preserve non-alphabetic characters unchanged.

Example:

Hi everyone,

I am currently setting up InterSystems API Manager (IAM) 3.4.3.11 using Docker. The installation is successful, the license is active, and I can access the Manager (port 8002).

I am now trying to secure the Administration Portal using basic-auth. I've found some documentation stating that I should:

1. Go to the Teams section in the UI.
2. Click on Invite Admin to create the first user.
3. Only then, enable KONG_ENFORCE_RBAC and KONG_ADMIN_GUI_AUTH in the docker-compose.yml.

The Problem: When I access the Manager (with RBAC disabled), I do not see any "Invite Admin" button or "T

We are implementing delegated auth between Kong Gateway and IRIS. Kong is correctly configured to forward JWT authenticated requests with consumer headers (X-Consumer-Username, etc.) to IRIS, but the ZAUTHENTICATE routine (deployed in the %SYS namespace) never executes, leaving ZW ^ZAUTHLOG empty despite successful header delivery.

Defining my first REST API within InterSystems using iris-rest-Api-template as a basis and I am seeing if someone could provide me some guidance to see if I can make it work.  

In some of my other posts, I have been trying to come up with a way for our Enterprise Application Development team which works with .Net to build Applications to make a REST call to our instance of InterSystems to query some of the Cache Tables we have defined. 

Using the iris-rest-api-template, I have created the osuwmc.DataLookup.REST.Base.cls

Hey everyone.

I have been taking a look at the External Language Server functionality to hook into some Dotnet functions, and I am hitting a bit of a wall.

Based on the example in the documentation here I can get the same result doing:

ENV>Set netGate = $System.external.getDotNetGateway()
ENV>Set netProxy=netGate.new("System.DateTime",0)
ENV>Write netProxy.Now,!
2025-12-3114:37:58.6022705

However, if I then try another system class, I get an error:

ENV>Set netGate = $System.external.getDotNetGateway()
ENV>Set netProxy=netGate.new("System.Convert",0)
ENV>Write netProxy.ToBoolean(123)

The most upvoted idea on the InterSystems Ideas Portal—garnering 74 votes—requests a lightweight version of IRIS. While the platform has grown into a powerful data engine, many projects require only its SQL database capabilities. This article demonstrates how to build an unofficial, compact IRIS Community Edition image focused solely on core database functionality, reducing the image size by over 80%.

⚠️ Disclaimer

This project produces an unofficial, experimental image of InterSystems IRIS Community Edition.

• Not supported or endorsed by InterSystems.
• Use at your own risk. The modifications remove core platform features and may break compatibility with tools, APIs, and expected behaviors.
• No warranties or guarantees apply, including fitness for production use.
• Intended only for educational and experimental purposes by advanced users.

Why a Lightweight IRIS?

While IRIS today includes rich functionality—interoperability, analytics, machine learning, system management, etc.—many projects only require its core SQL capabilities. The official Community Edition Docker image is approximately:

• Disk usage: 3.5–3.8 GB
• Compressed size: ~1.1 GB

IRIS Light reduces that to:

• Disk usage: ~575–583 MB
• Compressed size: ~144–148 MB

This makes it suitable for:

• Microservice or containerized SQL use
• CI pipelines with faster startup and pull
• Horizontal scaling where full features are unnecessary

There is a Master Table within IRIS that I am populating from Epic but want to share it with our Enterprise Application Development Team (Web). As a test I was able to use _SYSTEM from postman to execute the following.

POST /api/atelier/v1/xxxx/action/query HTTP/1.1

Dear Community,

As the 🎄 Festive Season 🎄 approaches, we’re excited to send our warmest wishes your way. May your holidays be filled with the joy of 🧑‍💻 learning, 🫂 connecting with fellow developers, and the thrill of new ideas and challenges waiting in the year ahead!

Looking back on 2025, we’re delighted to celebrate another year of remarkable achievements together with YOU, our incredible members:

I am migrating from HealthShare 2015 to Health Connect 2025 as part of an infrastructure upgrade. We have several C# .NET Razor web apps that interact with HealthShare using the InterSystems.Data.CacheClient assembly, and the Cache Object Binding Wizard for .NET to build the C# proxy classes. This has worked flawlessly for about 6 years.

I am now switching to using the Native SDK with the InterSystems.Data.IRISClient assembly and using the C# IRISReference and IRISObject. I have been able to rewrite nearly all the code in our web apps to use the new mechanism, with the exception of lists of o

Hi all, it's me again for sharing what I am studying recently.😓

Recently, I am studying how to setup OAuth2 authentication for the InterSystems FHIR repository. And I found the following articles are very good and easy to follow.😁

Building an FHIR Repository + OAuth2 Authorization Server/Resource Server Configuration on IRIS for Health Part 2

For me, as a user who do not have much knowledge about OAuth2.0. I think it quite difficult to understand how to setup the whole OAuth2.0 environment before knowing how's it look like (what is it? wh

Has anyone tried to authenticate IRIS client in Snowflake using Key Pair Auth as described in this doc?

I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

I was wondering if anyone had a way to automate creating the Query String for a FHIR Request?

Using HS.FHIRServer.Interop.Request in my development I have to specify the following...

I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?

I am trying to replicate a way to use FHIR as a way to query the EMR instead of using a MS SQL Stored Procedure that is populated via HL7 ADT to query.

Using a WSDL and the SOAP wizard I created a WebServiceClient, and Operation to send an encoded message to a Vendor. But the vendor is now sending back an HL7 in the SOAP response.

I tried updating the Operation to Extend EnsLib.HL7.Operation.ReplyStandard, but still use the EnsLib.SOAP.OutboundAdapter. When I did this it broke my Operation and would not compile with the following error...

ERROR #5478: Keyword signature error in osuwmc.Nutrition.HL7SoapOperation:Method:SendMessage, keyword 'method argument/s signature' must be 'EnsLib.HL7.Message,EnsLib.HL7.Message,%Library.String' or its su

I am looking for a way to capture Data Quality issues with the Source data that is populating HealthShare Provider Directory. 1 way is to use Managed Alerts, but since it could be multiple Providers and different messages it seems silly to alert on every message that has the error. Instead, I was thinking of using the Workflow Engine so it could populate a Worklist for someone to review and work.

Looking over the Demo.Workflow Engine example, I am not comprehending on how to send a task to the Workflow manager to populate the worklist from a DTL.

Does anyone have any examples on how this cou
