I have a class that extends %CSP.REST which made I deployed using $system.OBJ.MakeClassDeployed. After upgrading IRIS, the web app which uses that class no longer works with an ObjectScript error.

In the past, I fixed that problem by adding a dummy new line or a comment then recompiled that class. For this deployed class, I can't add a new line and recompile the class (the code shows up as locked in Studio). Simply running $system.OBJ.compile() is not fixing the web app issue.

Is there a way to edit a deployed class then recompile it?

Can someone help me understand what type of user error (?) is going on here please?

One one system, I write out a group of $c() values and get the expected results:

Hello Community,

When I compile the Sample.User class for the first time, and include an ObjectGenerator method intended to run certain logic during each compilation, it throws a <CLASS DOES NOT EXIST> error. However, recompiling the same class works as expected.

I understand this happens because the class hasn’t been fully compiled yet during the first pass. To overcome this issue, are there any specific callback methods available that can safely be used after the class is fully compiled?

Hi:

I see a lot of cool REST apps and i'm trying to host something in the TIE using REST/Axios with VITE.

At the moment i will probably host the application in web applications in Intersytems.

For authorisation and getting the logged in user and password to any app, is there a standard people are doing?

I.e. for axios you might have this from the app

Technical Documentation — Quarkus IRIS Monitor System

1. Purpose and Scope

This module enables integration between Quarkus-based Java applications and InterSystems IRIS’s native performance monitoring capabilities.
It allows a developer to annotate methods with @PerfmonReport, which triggers IRIS’s ^PERFMON routines automatically around method execution, generating performance reports without manual intervention.

In my previous article, Using LIKE with Variables and Patterns in SQL, we explored how the LIKE predicate behaves in different scenarios, from Embedded SQL to Dynamic SQL, and what happens to performance when wildcards and variables come into play. That piece was about getting comfortable writing a working LIKE query. But writing SQL that works is only the starting point. To build applications that are reliable, scalable, and secure, you need to understand the best practices that underpin all SQL, including queries that use LIKE.

This article takes the next step. We’ll look at a few key points to help strengthen your SQL code, avoid common pitfalls, and make sure your SELECT statements run not just correctly, but also efficiently and safely. I'll use SELECT statements with LIKE predicate as an example along the way, showing how these broader principles directly affect your queries and their results.

*This is what Gemini came up with for this article, kinda cute.

Hi all,

Let's do some more work about the testing data generation and export the result by REST API.😁

Here, I would like to reuse the datagen.restservice class which built in the pervious article Writing a REST api service for exporting the generated patient data in .csv

This time, we are planning to generate a FHIR bundle include multiple resources for testing the FHIR repository.

Some languages ​​have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.

The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?

Thank you!
