#Source Control

Source control (or version control) is the practice of tracking and managing changes to code. Source control management (SCM) systems provide a running history of code development and help to resolve conflicts when merging contributions from multiple sources.

Is your source control treating your InterSystems IRIS environment like a simple collection of files? Most source control tools lack the native intelligence to handle InterSystems IRIS, which is why your code is treated as such. 

Deltanji is different. It understands how code and other artifacts are stored within IRIS and can manage them directly. This eliminates the friction that other tools introduce to the process. 

Join us for an InterSystems-hosted webinar to see how Deltanji provides an enterprise-grade source control solution that is tightly integrated with your IRIS environment.

Welcome to the next chapter of my CI/CD series, where we discuss possible approaches toward software development with InterSystems technologies and GitLab.

Today I want to share a few approaches that will decrease your compilation time (especially if you're doing incremental/diff compilation rather than a full build).

Compiler flags and qualifiers

Code load and compilation are affected by a variety of flags and qualifiers. If you write deployment scripts for InterSystems platforms, I highly recommend reading them at least once through.

Question Michael Derr · Dec 4, 2025

We are a group of interface analysts in a healthcare setting, running IRIS for Health 2024, having upgraded over time from an old ENSEMBLE environment.  We have been working on a wish list of development goals, but are having trouble finding the correct, best practice method/path for getting to what we envision.

Current state:  We run IRIS for Health on a Redhat 8 virtual machine.  We run Interoperability productions (IE.cls) out of 6 namespaces.  We have a dev/test box and a production box.

  1. Introduction
  2. Version Control
  3. Exporting Classes
  4. Exporting BI Analytics classes
  5. Exporting globals

Introduction.

In this article, we'll cover a quick start to Git development with the InterSystems Developer Community and version control practices when working with IRIS InterSystems. We'll cover scenarios where we need to export Interoperability classes, globals, and analytics elements such as cubes and dashboards. These scenarios encompass key version control practices with IRIS.

To get started, you'll need:

  1. Register and log in to GitHub
  2. Be a member of the intersystems-community organization on Git

Getting started with IRIS InterSystems is very simple!

Question Arber Limaj · Nov 19, 2025

Hi everyone,
I'm getting prepared to take the following certification exam: "InterSystems IRIS Development Professional".

Can you give some advice on how to prepare (aside from the official course page: https://www.intersystems.com/certifications/intersystems-iris-development-professional/)?
Do you have examples of quiz questions that simulate the real exam or any material that helped you getting prepared?

Thanks you in advance,

Arber

Join us on Thursday to see the new features of Deltanji source control, version 8.1.

We'll be demoing our new Git Location Driver along with other functionality and usability improvements.

The Git Location Driver enables Deltanji to integrate directly with Git repositories, makes Deltanji the perfect source control companion to those who use Git-based repos by providing tighter integration with InterSystems IRIS.

Date: Thursday, July 17th 
Time: 11 - 12pm EDT | 4 - 5pm BST | 5 - 6pm CET
Location: Online (register for details)

Question Colin Brough · Jul 1, 2025

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

We have a service where 3 groups, each with multiple users, potentially have access to make changes to the live service. With the best will in the world, each group doesn't always tell every other group about changes made.
