The invention provides a combined verifying and authorizing method for a fixed
license and a floating
license, comprising the following steps that: a
client is connected with a
server, and starts application; the
server determines the verifying and authorizing type of the applied
license according to the currently applied configuration files; when the fixed license is verified and authorized, the
server determines whether the
client and the application are recorded in a license file stored in the server, and whether the
system time of the
client is posterior to the authorized
time limit, if the client and the application are recorded in the license file, and the
system time is not posterior to the authorized
time limit, the application is normally operated; and when the floating license is verified and authorized, the server determines whether the client and the application are recorded in the license file stored in the server, whether the
system time of the client is posterior to the authorized
time limit, and whether the number of the currently connected clients is less than the maximum
concurrency number, if the client and the application are recorded in the license file, the
system time is not posterior to the authorized time limit, and the number is less than the maximum
concurrency number, the application is normally operated.
