# WRlfTool - Manages the Redundant License File

WRlfTool is a Windows-interface program that allows you to create and maintain a redundant license file.

The WRlfTool utility by default distributes the license tokens for a redundant license among the redundant License Managers in the pool for high assurance.

Using Windows Explorer, navigate to the location of the wrlftool.exe file, and double-click the file to start the program. (The exact location of this file depends on your application vendor.)

The changes you make to the redundant license file will not take effect until you copy the changed file to a redundant License Manager in the pool (or edit it directly on the License Manager) and then restart that License Manager.

Creating and Maintaining the Redundant License File

1. To create a new redundant license file, go to the File menu and select New.
   To edit an existing redundant license file, go to the File menu and select Open and then select the desired file.
2. To add a new License Manager to the pool, click Add Server. You are then asked to type the host name and the IP address of the computer on which that License Manager resides. All the license License Managers in the pool must use the IP address to communicate.
3. Once you have added more than one License Manager to the pool, you can select one of the License Managers and click Move Up or Move Down to adjust its order in the pool. This sets it preference order. If the License Manager having first preference goes down, the License Manager with second preference will be elected as the leader, and so on.
4. At any time you can select a License Manager and click Delete Server to delete it from the pool.

Adding/Editing/Deleting Redundant Licenses

1. To add a redundant license to the pool, click Add License.
   You can access a screen that allows you to either add the license code or specify a file containing the license code.
2. Once you have added the license code, you see the View License screen. It displays information about this license such as the feature/version licensed, how many License Managers it is set up to use, and so on.

The license distribution will show all the token in the name of the leader.
