METHOD AND SYSTEM FOR RECONSTRUCTING PROCESSORS IN DISTRIBUTED COMPUTER SYSTEM, AND STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide the dynamic reconfiguration of quorum group of processors and its recovery procedure for a non-shared distributed computing system. SOLUTION: Even through at least one processor of the quorum group of the processors is unusable, assuming that the residual processors of the number of exist, the dynamic reconfiguration progresses. Recovery processing is carried out by a group of processors, as a result, at least one processor that is unusable during the dynamic reconfiguration of the group becomes active, and subsequently, the current state information can be obtained. The recovery processing includes the exchange of the incarnation numbers of processors to propagate the current state of the quorum group of the processors and lists of processors.
