Offline License

To enable offline licensing for your server, follow the steps outlined below. This documentation explains how to configure and manage offline licenses, including preflight mode and generating license

This functionality is available from application version 1.19.3

Overview

Offline licensing allows your server to operate without an internet connection. To configure the offline license, you need to set specific environment variables and follow a predefined process to generate and apply the license file.

Configuration

Generating License Request File

If you already have a functional DecisionRules instance running, you can skip Step 1 (Set Required Environment Variables) and Step 2 (Generate a License Request File).

You can generate the License Request File directly via a URL in your browser. Simply enter the following URL:

https://{API_URL}/offline-license/license-request

Where {API_URL} is domain of your running DecisionRules server instance.

For example:
https://api.decisionrules.io/offline-license/license-request

This will trigger the generation and download of the License Request File without requiring further configuration.

If you are setting up a new DecisionRules instance, follow the steps below.

Step 1: Set Required Environment Variables

1. Enable Offline License Mode

   • Set the OFFLINE_LICENSE environment variable to true.

   OFFLINE_LICENSE=true

2. Provide Your License Key

   • Set the LICENSE_KEY environment variable with the license key provided by DecisionRules.

   LICENSE_KEY=your_license_key_here

3. Optional: License File

   • If you already have your Licensse file, set it to the env variable.

   LICENSE_FILE=your_license_file // as single line string
   LICENSE_FILE_PATH=your_license_file // as path to your license file

Preflight Mode and License Request

If the application starts in preflight mode, it means the LICENSE_FILE environment variable is either missing or points to an invalid license file. The specific reason for preflight mode can be found in the server application logs.

Step 2: Generate a License Request File

1. Open client application and there should be License Request Page.

2. Download the License Request File. This file will contain the necessary information for generating the offline license file.

Step 3: Send License Request File

Send the downloaded license request file to [e-mail]. Ensure to include any additional context or requirements in the email.

Applying the Generated License

After receiving your license request, the DecisionRules team will generate the license file and send it back to you.

Step 4: Apply the License File

There are 2 options:

a) Set License file as string into environment variable.

1. Set the LICENSE_FILE environment variable

LICENSE_FILE=eyJrZXkiOiJvbDFkYm4wc0dGdE5aNndram1pckI1Q2duM.....

1. Restart your server to apply the license.

b) Set License file to your server and provide path

1. Save the provided license file to an accessible location on your server.

2. Set the LICENSE_FILE_PATH environment variable to point to the license file's location.

   LICENSE_FILE=/path/to/generated/license/file.lic

3. Restart your server to apply the license.

Example Environment Variable Configuration

Below is an example .env file configuration for enabling offline licensing:

Troubleshooting

• Preflight Mode Activated: If the server starts in preflight mode, check the server application logs for detailed reasons, such as:

  • Missing LICENSE_FILE environment variable.

  • Invalid or corrupted license file.

  • License key mismatch.

• Invalid License File: If the license file is rejected, contact [e-mail] for assistance.
