Configuration

Product Definition

To enable CBFL, you must create a QLM feature and associate it with your product as follows:

• Launch the QLM Management Console

• Go to the Define Products tab

• Select your product

• Add a new feature as follows:

  • Feature Name: CLOUD_FLOATING_LICENSE (or any name of your choice)

  • Feature Set: <select any feature set>, for example: 3

  • Feature ID: <default>, for example: 1

• Click Save to save your product

• Go to the Manage Keys tab and answer yes when prompted to upload the products to the server

License Wizard Settings File

The next step is to update the License Wizard settings file to instruct the wizard which QLM feature is associated with CBFL.

• Launch the QLM Management Console

• Go to the Protect your application tab

• Select your product

• Go to the "Customize look & feel" page

• Go to the "QLM License Wizard - Behavior Properties" section

• Set the QlmCloudFloatingLicenseFeature to: <FeatureSet>:<FeatureID>, for example: 3:1

• Click Next and save the XML settings file.

Implement CBFL in your Application

To implement CBFL in your application, you must perform the regular license key validation, similarly to node-locked licenses and in addition, you must do the following:

• When the application starts up after the license is validated, check out the license

• When the application exits, check-in the license

The QLMProFloatingLicense sample can be used as a reference to add floating license support to your application. The sample is located in the following folder: %Public%\Documents\Quick License Manager\Samples\qlmpro\Windows\DotNet\C#\QlmProFloatingLicense

In the sample, the Checkout/Checkin functionality is implemented in a new class called FloatingLicenseValidator which is a descendant of the LicenseValidator class.

Create license keys for CBFL

To create an Activation Key for a cloud-based floating license:

• Launch the QLM Management Console.

• Go to the Manage Keys tab.

• Click Create Activation Key.

• Set the Number of Activations field to the number of required floating licenses.

• Set any other property as needed.

• Click OK

Limitations

• You cannot edit a license and enable CBFL after the Activation Key is created. If you need to enable CBFL for a customer, you need to create a new Activation Key and set the CBFL feature at creation time.
