License Authorization Process

network address of the license server computer. The application sends a license
request to this address and the license server’s port.
Step 5: License Server Responds
When a license server receives a license request, it checks to see if a license can
be granted based upon the current license codes. If it can, then an authorization is
sent back to the client computer. Otherwise, the request is rejected and a denial is
sent back to the client computer. In both cases, the activity may be logged to a
file if this capability has been enabled.
Step 6: Client Renews License
Each license code specifies the maximum time period that a license may be held
by an application without renewal. After a client has received a license, it must
periodically request a license renewal from the license server. Forcing a license
to be renewed allows a license server to reclaim a license when there is a prob-
lem with an application or a client computer. If the application doesn’t renew its
license within the allowed time, it loses its license and the server may grant it to
another user. This action is handled by the application and is transparent to the
user on the client computer.
Step 7: License Server Responds
The license server responds to a license renewal request in the same manner as
the initial license request.
Step 8: Client Returns License
When an application ends, it sends a message back to the license server indicat-
ing that the license is no longer needed. This lets the license server immediately
reclaim the license and make it available to another user.
