Working with Detachable Licenses

A detachable license is an SL license for a Product that can temporarily be removed from a pool of network seats and attached to a remote recipient machine. For example, the license for a Product may be detached from the network and attached to a laptop to enable a user to use the protected application while working offline. When a license is detached from the network, the license includes all Features in the Product that have been designated as detachable, and all protection key memory for the Product.

Each instance of a detachable license relates to a specific recipient machine.

A detachable license expires after a specified time, after which the license is automatically returned to the pool of network seats.

You have the option of canceling the detachable license on the recipient machine and returning the license to the pool of network seats before the license expires.

This section describes:

• Defining a Product with a detachable license
• Additional considerations when defining detachable licenses
• Preparing a recipient machine for running a detached license
• Detaching a license from the network
• Attaching a license to a recipient machine
• Canceling a detachable license from the recipient machine

Defining a Product with one or more Detachable Licenses

Products with detachable licenses are defined in the Create Products page, in the same way as other Products are defined. However, certain attributes are required at both Product and Feature level to enable detachable licenses.

To define a Product with a Detachable License:

• In the Products page, click New Product. The Create Product pop-up appears. (The steps specific to defining detachable licenses are provided here. Refer to the Create Products page for detailed steps.)
• From the Protection Type drop-down list, select LDK License.
• In the Name field, enter a name for the product (maximum length 50 characters). The name must be unique in the selected batch.
• In the Locking Type drop-down list, select one from the following options:
  • SL-AdminMode
  • HL or SL-AdminMode
  • HL or SL-AdminMode or UserMode
• To specify Features in the Product,
1. Click Add Features. The Add Features to Product pop-up appears.
2. Select the Features to add. Click Add Features to Product. The associated Features are displayed in the main screen.
3. To remove a Feature from the Product, click Remove in the same row. To remove multiple Features, select the check boxes and click Remove.

You can add Features that will have detachable licenses and Features that will not have detachable licenses to a Product.

• In the Product Features pane, select the Features for which you want to enable a detachable license, then click Configure. The Configure License Terms pop-up appears.
• In the License Type drop-down list, select either Perpetual or Expiration Date.
• Select the Concurrency check box, then specify your concurrency preferences.
• Ensure that the Allow Detaching check box is selected.
• In the Accessibility area, ensure that the Network check box is selected.
• Click Save. The Configure License Terms pop-up closes and the Create Product page is displayed.
• Click Save as Draft to save the Product as Draft. Click Save as Complete to mark the Product as Complete.

Additional Information about Detachable Licenses

If you create an Entitlement in which you have several Modification Products that have been created from a single Base Product and one Modification Product has a Feature that is detachable and another Modification Product has the same Feature ID but it is not detachable, the Feature values for the last added Product will be applied.

Only the Features for which the detachable options have been enabled will be included in a Product that is detached from the network.

Preparing a Recipient Machine to Run an Application using a Detached License

In Entitlement for a recipient machine to run an application using a detached license, the Sentinel LDK Run-time Environment and vendor libraries must be installed. This is accomplished by creating a Run-time Environment Installer that automatically installs these components.

To prepare a recipient machine for a Detached License:

• On the main menu, click Developer > RTE Installer. The RTE Installer page appears.
• Clear the Include V2C for Bundle of Unlocked Products check box.
• Click Generate.
• Save the generated installer file.
• Use the generated file to install Sentinel LDK Run-time Environment on the recipient machine.

Detaching a License from the Network

You use Sentinel LDK ToolBox, the Sentinel Licensing API, or Sentinel Admin Control Center to detach licenses from the network. The process is described in the help documentation for each of these applications.

Attaching a License to a Recipient Machine

A detached license is attached to a recipient machine by running the file that is created when a license is detached from the network. For more information, see the help documentation in Sentinel LDK ToolBox, the Sentinel Licensing API, or Sentinel Admin Control Center.

Canceling a Detachable License from the Recipient Machine

Typically, a detachable license returns to the pool of network seats automatically when the license expires. You have the option of canceling a detachable license that has been attached to a recipient machine before the license expires and returning the license to the pool of network seats. This action must be performed from the recipient machine. For more information, see the help documentation in Sentinel LDK ToolBox, the Sentinel Licensing API, or Sentinel Admin Control Center.
