Software execution management apparatus, method, and computer-readable medium thereof

A software execution management method executed by a first computer managing software execution and a second computer replacing the first computer, the software execution management method comprising:

• determining, by the first computer, availability of a process for permitting execution of software by a client in accordance with first license information stored in a storage area, the first license information relating to permission for executing the process for permitting execution of the software;
• detecting, by the second computer, the first computer in accordance with the second license information stored in a storage area, the first computer being still executing the process for permitting execution of the software, the second license information including an identification code for identifying a license to be invalidated, the software being permitted to be executed by the client in accordance with the license to be invalidated according to the second license information,
• transmitting, by the second computer, an invalidation signal to the detected first computer for limiting execution of the process of the first computer to permit execution of the software by the client, in accordance with the second license information;
• and
• limiting, by the first computer, execution of the process for permitting execution of the software by the client, regardless of the first license information, upon receiving the invalidation signal.

A non-transitory computer-readable medium storing a program that causes a computer that is communicably connectable to a client to execute software execution management, the computer being capable of acting as a first server managing software execution, the first server being replaced by a second server, the computer being capable of acting as a third server replacing a fourth server managing software execution, the software execution management comprising:

• storing first license information and second license information, the first license information relating to permission for executing a process for permitting execution of software, the second license information including an identification code for identifying a license to be invalidated;
• determining, in accordance with the first license information, availability of the process for permitting execution of the software;
• detecting when the computer acts as a third server, in accordance with the second license information, the fourth server which is still executing the process for permitting execution of the software, the software being permitted to be executed by the client in accordance with the license to be invalidated according to the second license information;
• transmitting when the computer acts as the third server, to the detected fourth server a first invalidation signal according to the second license information for limiting the process of the fourth server for permitting execution of the software by the client;
• and
• limiting when the computer acts as the first server, the process for permitting execution of the software by the client, regardless of the first license information, upon receiving a second invalidation signal from the second server.
