Title:
RECORDING MEDIUM WITH RECORDED PROGRAM DECIDING SERVER COMPUTER HAVING PERFORMED PROCESSING FINALLY AND HIGH- AVAILABILITY COMPUTER SYSTEM
Document Type and Number:
Japanese Patent JP3967509
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To actualize automatic operation by eliminating the limit of the frequency of hand-over of a processing and to improve decision precision by deciding a server having performed a process finality by using only local information.
SOLUTION: When a fault occurs in at least one server 100a or 100b and when the server recovers from the fault, the cluster management part 110 of the server shifts server state according to a state transition chart 800. A state write part 710 records server priority 210 determined by the server state that state change information 901 indicates on disk drivers 200a and 200b. A comparing processing part 720 decides whether or not its server has higher priority according to at least the priority 210 of its server if a fault occurs to the servers 100a and 100b and at least its server recovers from the fault thereafter. The cluster management part 110 makes a corresponding state shift according to the decision result and state transition chart 800.
