ABSTRACT:
A distributed processing system which performs cooperative processing by client processes and server processes in a plurality of systems interconnected through a network. The distributed processing system comprises a system supervisor which controls the booting and shutdown of the respective systems and is connected to the network. Connected to the system supervisor is a client-server database which accumulates information related to the clients and servers for determination of systems to be booted or shut down and their booting or shutdown sequence.
The system supervisor comprises a recognition unit which recognizes the status of and a boot or shutdown request for each system; a boot request controller which determines systems to be booted and the their booting sequence and requests booting; a boot request send unit which sends the boot request to the system concerned; a shutdown request controller which determines systems to be shut down and their shutdown sequence and requests shutdown; a shutdown request send unit which sends the shutdown request to the system concerned; and a status information collection unit which collects information from each system.
Each system comprises a boot request receive unit which receives a boot request, a boot execution unit which executes the booting of the system in response to the boot request, a shutdown request receive unit which receives a shutdown request, a shutdown execution unit which executes the shutdown of the system in response to the shutdown request, and a status information provision unit which informs the system supervisor of the booting and shutdown of the systems and the status of the clients and servers.
