Cloud License Reclamation

Overview

[The Reclamation service described below is available as of QLM v20.0.26177.5]

When using QLM Cloud Licenses, your QLM-protected application includes a built-in timer (via the QlmCloudFloatingLicenseHelper class) that periodically contacts the server to verify whether the license is still checked out.

License Validation Frequency

You can control how often this validation occurs by setting the QlmCloudFloatingLicenseHelper.QlmTimerFrequency property.

Note: For Soraco-hosted license servers, the minimum allowed validation interval is 3 hours.

Each time a client validates a license with the server, the Last Accessed Date of the license is updated (requries QLM v20.0.26177.5).

License Reclamation

License Reclamation relies on the Last Accessed Date to determine whether a license is still actively in use.

As long as your application remains open, it continues to send heartbeat signals to the server, ensuring the license is considered active. A license is typically considered inactive in scenarios such as:

• The computer is shut down

• The computer goes to sleep

• The computer goes offline

• The application crashes

Inactivity Threshold

During the reclamation process, the server compares the Last Accessed Date with the current date to decide whether a license is deemed inactive.

You can configure the inactivity window using the Inactivity Threshold setting:

• Navigate to: QLM Management Console → Manage Keys → Options → Cloud Licenses

This setting defines how long a license can remain inactive before being reclaimed.

Offline Licenses

If a license was checked-out for offline usage, the reclamation process honors the offline expiry date. If the offline expiry date has been reached, the license will be reclaimed.

Reclamation Process

The reclamation can be triggered automatically via the QLM Agent service or manually.

When enabled, the QLM Agent Service contacts the server at regular intervals and performs the reclamation process.

To manually trigger the reclamation process, go to QLM Management Console → Manage Keys → Options → Cloud Licenses and click 'Reclaim inactive licenses now".

Configuration

To enable automatic license reclamation:

• Launch the QLM Management Console

• Go to the Manage Keys tab and select Options

• Go to the Cloud Licenses tab

• Select your License Server

• Set the Inactivity threshold in minutes

Note: For Soraco-hosted license servers, the minimum allowed value is 3 ½ hours (210 minutes).

• Set the Reclamation timer frequency in minutes

Note: For Soraco-hosted license servers, the minimum allowed value is 6 hours (360 minutes).

• Select "Enable the QLM Agent to automatically reclaim licenses"

Note that the QLM Agent Service must be running on your workstation.

Important Note

If you have upgraded from a previous version of QLM, you should wait 24 hours following the upgrade before enabling license reclamation. If you do not, licenses that are still active will be reclaimed.
