The License Activation and Approval

The license management page is divided into two sections, "Summary" and "Role". The "Summary" section shows the health state of the license, Server Key, Serial Number and current license status. Users can start and stop users’ license cluster service by clicking "Start" and "Stop". The "License Details" section shows the current License type, version, node capacity, and License expiration time for each installed service. The "roles" section shows the nodes where the roles of the licensed services are running and the health state of each role.
