摘要： A storage device for which restoration of data is possible without the need for excess equipment includes mirrored storage units for online use and for backup, and is capable of performing a data backup while continuing input and output of data. The storage device is further provided with an update data storage unit for storing update data. According to the storage device, even if the information stored in a storage unit for online use is not capable of being read because of a fault in the storage unit, it is possible to restore the data in the backup storage unit to the state that existed in the storage unit for online use immediately before the fault by applying the update data to the information stored in the storage device for backup.

摘要： A scheme for restarting processes at distributed checkpoints in a client-server computer system, in which a fault in one client computer does not affect the server computer and the other client computers. In this scheme, a fault occurring in one computer among of a plurality of computers constituting a client-server computer system is detected while these plurality of computers are executing respective processes, and whether that one computer in which the fault is detected is a server computer or not is judged. Then, related processes executed on these plurality of computers are restarted when that one computer is judged as the server computer, whereas no process executed on these plurality of computers is restarted when that one computer is not judged as the server computer. It is also possible to specify a restart information for each process indicating how processes should be restarted when a process fault occurs in each process, and to restart selected processes executed on these plurality of computers according to the restart information for a process in which the process fault is detected.

摘要： A commit controlling scheme for a transaction processing in a system utilizing the check point/roll back scheme, which is capable of guaranteeing the reliability of data of the transaction processing even when the transaction processing and the check point/roll back scheme are employed simultaneously, is described. An issuance of an external output for notifying to a user that a transaction has been committed is delayed until after a new check point for the transaction processing process is generated by the fault recovery mechanism at a timing later than a commit of the transaction by the transaction processing process. This can be realized by delaying an issuance of a transaction commit notice from the transaction processing process, or by intercepting a transaction commit notice sent from the transaction processing process, or else by delaying an issuance of the external output by the client process after receiving a transaction commit notice from the transaction processing process.

摘要： A process state management scheme capable of acquiring process states consistently even in a case where a new process is generated from some process, while using the synchronous checkpointing method. This scheme prohibits a new process generation during a process state acquisition, which can be realized by judging whether a process generation request by a first process for generating a second process is prior to a process state acquisition request or not, and generating the second process from the first process accordingly. This scheme also prohibits a process state acquisition during a new process generation, which can be realized by acquiring a process state at each of the first and second processes after a notice of the identifier of the second process from the first process is received, when a notice of the identifier of the second process from the second process is prior to the notice from the first process.
摘要翻译：即使在使用同步检查点方法的情况下，即使在从某个处理生成新处理的情况下，也能够一致地获取处理状态的处理状态管理方案。该方案禁止在处理状态获取期间的新的处理生成，其可以通过判断通过用于生成第二处理的第一处理的处理生成请求是否在处理状态获取请求之前来实现，并且从第相应的第一个过程。该方案还禁止在新进程生成期间的进程状态获取，这可以通过在从第一进程获得第二进程的标识符的通知被接收到之后获取第一和第二进程中的每一个处理状态来实现，来自第二进程的第二进程的标识符的通知在从第一进程通知之前。
