To be able to execute graphs, CloverDX Server requires a valid license. You can install and run CloverDX Server without any license, but no graph will be executed.

    There are three ways of installing the license. They work on all application servers and can be used at the same time, but only the most recent valid license is used.

    We recommend using the first and easiest option (for other options, see CloverDX Server Activation Alternatives):

    CloverDX Server Activation using Web Form

    If the CloverDX Server has been started without assigning any license, click the Activate server link on the welcome page. You will be redirected to the Add New License form where you can upload the license file using the Browse button, or simply copy the license from the file and paste it into the License key text field.

    After clicking the Update button, the license is validated and saved to the database table clover_licenses. If the license is valid, a table with license's description appears. To proceed to CloverDX Server console click Continue to server console.

    You can skip adding a license by clicking the Close button.

    Updating CloverDX Server License in the Configuration Section

    If the license has been already installed, you can still change it by using form in the Server web GUI.

    • Go to server web GUIConfigurationSetupLicense

    • Click Update license.

    You can paste a license text into a License key text area or use the Browse button to search for a license file in the filesystem. To skip adding a license, click the Close button.

    After clicking the Update button, the license is saved to the database table clover_licenses and reloaded.

    The CloverDX license can be changed at any time by replacing license.dat file. Afterwards, you have to let CloverDX Server know the license has changed.

    • Go to server web GUIConfigurationSetupLicense

    • Click Reload license.

    • Alternatively, you can restart the CloverDX Server application.


    The license in the database is common for all nodes in the Cluster. Reloading of the license occurs on each node in the Cluster.
