For the question in the Title, the AI Chat gave a response of:


The ‘Current Users’ value displayed by the $System.License.ShowSummary() method represents
real-time license usage tracked in shared memory on the local system.

We are trying to reconcile which user/process are associated with the counts that are returned.

Does anyone know how to get the detail of 'license usage tracked in shared memory on the local system.'?

Thanks you for your time.

- Patrick

I need to read first six characters from the filename we process in healthconnect, then need to insert these six characters in MSH-6 in the same HL7 message. (please note each file can have multiple HL7 messages with multiple MSH segments)

Is something can be done when first process the file, then insert first characters MSH-6?

Please advice if this is an easy fix.

Hello Community! As another great year comes to a close, I wanted to notify you about an upcoming change to the vscode-objectscript extension. In an effort to reduce the extension's footprint, simplify maintenance, and improve ease of use, InterSystems plans to remove some rarely-used configuration settings. Our telemetry tells us that these settings are changed from the default by fewer than 2% of users. However, before finalizing the removal I would like to give any users of these settings the opportunity to explain why a setting shouldn't be removed.

It was encouraging to see more people building VS Code extensions for the recent contest. However I noticed that of of the three extensions requiring credentials with which to make their connections only mine, gj :: dataLoader, leverages the long-established and officially-supported InterSystems Server Manager extension to obtain the connection definitions and to handle credentials securely.

Supply Chain Orchestration for dummies

Supply Chain refers to a set of processes and activities performed by the company's business areas and its suppliers and partners (stakeholders), from the acquisition of raw materials, through production, to delivery to the end consumer. It can be better managed using SCM solutions with the orchestration of the InterSystems IRIS:

The previous article introduced IrisOASTestGen, a tool designed to generate REST API test code for InterSystems IRIS based on OpenAPI 2.0 specifications. It demonstrated how to scaffold test cases using the default templates bundled with OpenAPI Generator.

This follow-up focuses on the next natural step: customizing the generated test code.
By extending the code generation logic with Mustache templates, it becomes possible to express richer semantics, implement CRUD-aware tests, and create more meaningful test suites.

Modern SQL engines are enormously complex pieces of software. Even when they appear stable and mature, subtle bugs can hide in their optimizers, type systems, predicate evaluation, or execution layers. These bugs rarely announce themselves loudly. Instead, they quietly produce incorrect results, behave inconsistently, or fail abruptly under specific combinations of SQL constructs.

This is precisely why tools like SQLancer exist. SQLancer automatically generates SQL queries and uses logical “oracles” to detect when a database behaves incorrectly. It has revealed hundreds of real bugs in widely used systems such as MySQL, PostgreSQL, SQLite, and DuckDB.

With this in mind, I attempted to bring SQLancer to InterSystems IRIS, starting with the NOREC oracle — a powerful method for detecting optimizer correctness issues. The journey, however, uncovered not just potential SQL correctness problems, but also a surprising number of driver-level and server-level failures that prevented SQLancer from running at full strength.

This article summarizes why SQLancer is important, how the NOREC oracle works, and what unexpected findings appeared while testing IRIS.

One of the newest features of .Net core 10 with C# 14 is the file-based apps. This feature allows you to execute C# code in a simple .cs file without the need to create a solution, a project, or any of the related structure.

For example you can create a script.cs file using the notepad with the content:

Console.WriteLine(“This is a script in c#.”);

Then in the command line or the terminal you execute the command:

Hello Developers! 👋
I’m excited to introduce IRIS IO Utility, my submission for the InterSystems "Bringing Ideas to Reality" Contest 2025. This VS Code extension provides you an intuitive and powerful interface for importing and exporting data without leaving your IDE.
