Attributes in a license file define the number of Unwired Server instances allowed to run concurrently, the number of mobile clients that can connect to the Unwired Platform system, and the license expiration date.
Each Unwired Server instance must have its own server license. In an Unwired Server cluster, all nodes can share a common pool of mobile client licenses.
At startup: If the Unwired Server cannot retrieve the number of licensed servers from the license file, or if the server is not licensed, the Unwired Server stops (or enters the license grace period, if any).
At mobile client connection: When a mobile client connects, the Unwired Server checks to see if that client exceeds the client license limit. If so, the Unwired Server throws a license check exception to the client. Otherwise, the connection continues and operations proceed normally.
The Unwired Server writes all license errors to the log.
