InterSystems FAQ rubric 

When connecting to the database using a client-server architecture, for example using language binding, the machine name of the client can be obtained using the following code:

set client=##CLASS(%SYS.ProcessQuery).Open("P"_$j).ClientNodeName

In the previous article, we saw in detail about Connectors, that let user upload their file and get it converted into embeddings and store it to IRIS DB. In this article, we'll explore different retrieval options that IRIS AI Studio offers - Semantic Search, Chat, Recommender and Similarity. 

New Updates  ⛴️ 

• Added installation through Docker. Run `./build.sh` after cloning to get the application & IRIS instance running in your local
• Connect via InterSystems Extension in vsCode - Thanks to @Evgeny.

Keywords:  Vibe coding, Windsurf, IRIS, TIE

Why not?   "Vibe coding" is never about the vibe!

Has anyone not been trying "vibe coding" so far?

Even merely 3 years ago, if anyone asked

• "Could I do IRIS implementation for NHS TIE in English or Spanish or just Chinese ?", or
• "Can I just instruct TIE in English to build itself an e2e route, to pick up a PDF report then turn into ORU/MDM message and submit into the PAS ?", or
• "Could we query IRIS database in English only, and build up dashboard or ad hoc report of my own by English instructions?

Data Collection

This is a step-by-step instruction guide for creating a task to collect data about the InterSystems database and globals therein (as seen in the associated Open Exchange App - find all the associated code there)

UPDATE (Aug 1 2024): Recently I've been asked about the differences between this and the History Monitor functionality. In short, the data collection monitor builds on the history monitor by adding the ability to track growth of individual globals.

Hi Community!

We’re excited to announce the launch of a new, hands-on training program:

 🧑‍💻 Developing FHIR Applications Using Python 🧑‍💻

This cohort-based course takes developers from FHIR fundamentals to advanced, real-world healthcare interoperability solutions, with deeper, more practical coverage than typical industry offerings and a strong focus on production-ready skills using InterSystems technology.

I need to reproduce a table (in fact a view, but let's start with a simple table 😊) in IRIS as the currently used in Oracle.

I need to expose/project one column to JDBC as CLOB, in my class I have the corresponding property defined as:

Property GlobStream As %Stream.GlobalCharacter;

In JDBC this column is projected as LONGVARCHAR, this is compliant with the documentation but I need to project it as CLOB.

In addition, I'm no expert in JDBC but wit seems that LONGVARCHAR has a Maximum Length 32,700 characters in JDBC, not quite enough for an arbitrary stream.

This is an excellent candidate for a developer community post (like Dev.to, Medium, or the InterSystems Community). It bridges the gap between high-level architecture and hands-on implementation.

Here is the summarized article format.

Building a Robust Asynchronous Queue Manager with InterSystems IRIS and Angular

As applications scale, handling heavy computational tasks synchronously becomes a bottleneck. Whether it's processing large data sets, sending high-volume emails, or managing API integrations, a decoupled architecture is essential.

Project Overview:

The Clinical Staff Master Data Management (CSMDM) system is a full-stack healthcare integration application built on InterSystems IRIS for Health. It centralizes and standardizes clinical staff metadata into a single authoritative repository, exposed through RESTful CRUD APIs and reusable backend methods.

The platform eliminates fragmented lookup tables and hardcoded mappings that commonly cause errors in HL7 and FHIR integration workflows, ensuring data consistency and interface reliability.

Hi Developers!

Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices? 

if 10K lines OK? How do you cope with it? Please share?

Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

s r = ##class(User.ADGroup).%New()
s json = {"code": "123", "text":"456", "oazisCode": ["1","2"]}
d r.%JSONImport(json)
w r.oazisCode.

I was having trouble with some dimension based calculated members defined in Analyzer.  They would work and then not work.   At one point I had two identical calculated measures, same code, same specification and one would work and one would not.  I was trying to set them up in "shared storage", that checkbox in the calculated member dialog that should allow the measures to be used across multiple pivots.

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite select top 10 ID from some_table where row_status in ('I','U') order by ID - the same select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I want to implement isc-rest in my new project iris-budget/module.xml at master · oliverwilms/iris-budget

I get this error:

#8 11.30 Building dependency graph...
#8 12.69 ERROR! Could not find satisfactory version of isc.rest in any repositories. Required by: iris-budget 0.0.1: ^2.0.0
#8 ERROR: process "/bin/sh -c iris start IRIS && \tiris session IRIS < iris.script &&     ([ $TESTS -eq 0 ] || iris session iris -U $NAMESPACE \"##class(%ZPM.PackageManager).Shell(\\\"test $MODULE -v -only\\\",1,1)\") &&     iris stop IRIS quietly" did not complete successfully: exit code: 1
 

In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

     ⏯  Optimizing Query Performance in Health Insight @ Ready 2025

I am working on a new project oliverwilms/iris-budget
based on intersystems-community/iris-fullstack-template: This template shows you how to build, test and deploy a simple full-stack application using InterSystems IRIS REST API

I do not understand why I get this error:

Hi Community,

Here we have requirement to process messages min 10 sec delay. Current time it is taking my businessProcess is less than 1 sec.

To implement this requirement , I need to sleep 10 sec in business process custom code.

Could somebody help me to implement delay in BusinessProcess.

Thanks,

Prashanth

Hey everyone,

I'm just seeking some guidance and confirmation on what I'm doing for my production health monitoring.

We utilize Grafana to have reporting/monitoring dashboards and I have made a REST API to query the health of our productions. I believe I have everything figured out except for one thing that I'm uncertain about and that is the Production Item Color indicators:

Is there an easy way of being able to figure out the status of an item with the legend above? Ideally, I'd like to have this data in my JSON response.
