IIS - Not invoking .cls

Hello,

I have problem to get working my web application in IIS. On apache just works fine.

I had an app in wwwroot called test, there is index.html file where is tag

 <body onload="document.location='/test/app.start.cls';">

When I do localhost/test. Then my application works just fine.

I have created second one in management portal called /mobile

mobile is in wwwroot/test/mobile where is the same index.html with tag

 <body onload="document.location='/mobile/app.mobile.start.cls';">

When I do localhost/mobile I got HTTP Error 404.0 - Stream Not Found

Requested URL    http://localhost/mobile/app.mobile.

Avoiding SQL Injection in InterSystems IRIS: The Case for Secure Query Practices

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

The Problem: Dynamic SQL and SQL Injection

Dynamic SQL constructs queries as strings at runtime. While this offers flexibility, it also creates a vulnerability if user input is not handled correctly.

Cannot lock hslib err(13) on Container

We are trying to run the HS solution inside of a container, but we are getting the following errors un start up

Adding `nfsiostat` to SystemPerformance

Already included in SystemPerformance

There are nfs disk commands (including nfsiostat) included with SystemPerformance, but disabled by default. Enable them by running:

$$Enablenfs^SystemPerformance()

Doing so will add the following nfs commands, for example, on Linux:

  1. /usr/sbin/nfsstat -cn
  2. /usr/sbin/nfsiostat [interval] [count]

Ensure the commands are installed and runnable from the OS :)

This can be subsequently disabled via $$Disablenfs^SystemPerformance()

Adding a generic command to SystemPerformance

Adding an arbitrary OS tool creates a "user" command under ^IRIS.

Do you use client-side editing in VS Code? We want your feedback on the latest improvements!

Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.

What Changed

Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.

%ZEN.Dialog.namespaceSelect is not showing in some namespaces and giving a 403 Page not found error. Any ideas what could be wrong?

I have an issue and can't seem to find the problem.

Issue

 In some namespaces i get a 403 Page not Found error for healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.namespaceSelect.cls ; healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.finderDialog.zen  && healthconnect/csp/healthshare/[NAMESPACE]/_CSP.UI.Portal.About.zen

 

Iris setup

It is currently configured in a mirror group and on the other mirror-member i don't encounter the issue. (I have checked if it was because of the member-type Primary and Backup). 

The user that I am using has the %All role.

Developing and maintaining code for interoperability components within a healthcare institutional environment

There are lessons we learned from developing and maintaining code for interoperability components within a healthcare institutional environment.

The plane is already flying

Be prepared to rebuild, improve, extend, and fix the plane mid-flight.
 

Maintenance windows for hospital systems are often very limited, with some required to be operational 24/7. While the health critical systems such as imagery modalities or registration kiosks — or at least their critical functions — must operate autonomously, efficiency and usability may be compromised when interoperability components malfunction.

Python method does not work in Business Process

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

Rebuilding the IRIS Production Monitor as a Modern Angular App — Looking for Feedback

Hi community,

I've been working on a side project that I'd love to get some eyes on: a ground-up rebuild of the classic IRIS Production Monitor using a modern web stack. The existing ZEN/CSP-based portal does the job, but I wanted to explore what a contemporary, real-time version of it could look like.

What it is

A standalone Angular web application that connects to any Interoperability-enabled IRIS namespace and gives you a live view of your production — services, processes, operations, queues, event log, and message traffic — all in one screen.

Dark Mode for HealthShare Management Portal - Visual Accessibility Need

Hello InterSystems Community,

I hope you're all doing well. I'm reaching out to ask if there's any way to enable a dark theme or dark mode for the HealthShare Management Portal.

Background

I have a visual impairment (amblyopia/lazy eye) which means I'm nearly blind in one eye. Like many people with visual difficulties, I find that bright white backgrounds and interfaces cause significant eye strain and fatigue. This makes it challenging to work with the Management Portal for extended periods.

Building a Medical History Chatbot - FHIR, Vector Search and RAG for beginners

Introduction

Earlier this year, I set about creating kit to introduce young techy folk at a Health Tech hackathon to using InterSystems IRIS for health, particularly focusing on using FHIR and vector search.

I wanted to publish this to the developer community because the tutorials included in the kit make a great introduction to using FHIR and to building a basic RAG system in IRIS.

How to add your APIs to the Interoperability Production

I may have mentioned this before: I believe the Visual Traces, these sequence diagrams with full content of each step, are a fantastic feature of the IRIS Data platform! Detailed information about how the API works internally, as a visual trace, can be very useful for projects on the IRIS platform. Of course, this applies when we are not developing a high-load solution, in which case we simply don't have time for saving/reading messages. For all other cases, welcome to this tutorial!

How to set up an IRIS Sharding cluster in less than a minute

In this article I'll show you how to set up in your laptop, very quickly, a cluster of IRIS nodes in sharding. It's not the goal of this article neither to talk about sharding in detail nor define a deployment of a production ready architecture, but to show how to set up quickly, in your own machine, a cluster of IRIS instances configured as shard nodes, with which you'll able to play and test this functionality. If you're insterested in knowing more about sharding in IRIS, take a look at the documentation clicking here.  

First and foremost, I want to remark that IRIS sharding will allow us 2 things:

  • Define, load and query shard tables, which data will be distributed transparently between the cluster's nodes
  • Define  federated tables, which offer a global and composed view of data belonging to different tables that will be physically stored in different distributed nodes

So, as I said, we let for other article playing with shard or federated tables, and just focus now in the previous step, that is, setting up the cluster of shard nodes.

ObjectScript Search — Full-Text Server-Side Search for VS Code, Right Now

ObjectScript Search icon

If you have ever dug through a large IRIS namespace looking for where a particular string, method call, or pattern was used, you know the pain: there was no built-in way to do a grep-style search across your server-side ObjectScript code from VS Code — at least not without jumping through some hoops.

That is what ObjectScript Search fixes.

Try it today with a simple install from the VS Code Marketplace. If you don't like it, uninstalling is just as easy. But I think you will like it — it is a huge quality-of-life improvement for anyone doing ObjectScript development in VS Code.
