Distributed Execution with AOS using multiple repositories

As of Tricentis Tosca 2026.1 LTS, Distributed Execution is no longer enabled by default. While Distributed Execution is included in both Tosca Commander and Tosca Server installations, it requires manual activation:

  • Tosca Commander: The Distributed Execution Agent option in the installer is disabled by default. You must enable it before starting the Tricentis Tosca installation.

  • Tosca Server: All Distributed Execution related services remain disabled by default. You must enable the DEX Server after the Tosca Server installation.

For detailed information how to enable the Distributed Execution Agent and DEX Server, see this Tricentis Knowledge Base article.

Typically, you use Tosca Distributed Execution with Automation Object Service (AOS) with one common repository. All users and AOS workspaces are connected to this repository.

If you work on multiple projects that are split between multiple repositories, you can set up Tosca Distributed Execution with AOS to work with multiple repositories:

    • Make sure that the name of the first workspace you create contains only alphanumeric characters and underscores _. Don't use any other special characters.

    • Make note of the project root name, which you'll need in the next step.

  2. Create AOS workspaces for each repository.

  3. If you have additional user machines, perform these actions:
