协调分散式系统中的故障复原;COORDINATING FAULT RECOVERY IN A DISTRIBUTED SYSTEM

摘要

在各种实施例中，提供在主机与租客之间协调分散式系统中租客基础架构之故障复原的方法及系统。决定分散式系统中的租客基础架构的故障发生。故障发生可为支持租客之服务应用程式之租客基础架构之软体故障或硬体故障。将故障复原计划传递至租客以通知租客故障发生及恢复租客基础架构所采取的动作。决定是否自租客接收故障复原计划回应；故障复原计划回应系来自故障复原计划之租客的应答。在接收到故障复原计划回应后或在预先界定之时间限制到期时，执行故障复原计划以恢复租客基础架构。; the fault recovery plan response is an acknowledgement from the tenant of the fault recovery plan. Upon receiving the fault recovery plan response or at the expiration of a predefined time limit, the fault recovery plan is executed to restore the tenant infrastructure.
