License Manager Simulator

A License management simulator project for testing license integration in user applications.

About The Project

The License Manager Simulatoris an application that simulates several license servers output for use in the development of applications which interface to the license servers.

It contains fake binaries that simulate the license servers output.

License servers supported:

• FlexLM
• RLM
• LS-Dyna
• LM-X
• OLicense

Installation

$ python -m venv .venv
$ source .venv/bin/activate
$ pip install license-manager-simulator

The scripts will be available inside the bin folder in the venv.

Prerequisites

To use the License Manager Simulator you must have Slurm and License Manager Agent charms deployed with Juju. Instructions for this can be found at the License Manager documentation.

For each license server supported, there's a script that requests license information to the simulator API and a template where the data will be rendered.

You also need to add licenses to the Simulator API and to the Slurm cluster, and then copy an application file to the slurmd node to run a job.

Usage

There is an application.sh script that is intended to run in Slurm as a job that uses the licenses from the Simulator API. It is just a dummy application for testing purposes that creates a license_in_use in the API, sleeps, then deletes the license_in_use. There is also a batch.sh script to run the application via sbatch.

These files need to be updated with the Simulator API IP address provided in the step above before being copied to the /tmp folder in the slurmd node.

To submit the job, run:

$ juju ssh slurmd/leader sbatch /tmp/batch.sh
