ABSTRACT:
A data access management system in a distributed processing system capable of immediately restoring the system as a whole, has computers connected to each other via LAN, and a secondary storage device to which the computers are connected via data transfer paths. An access control subsystem for executing a data access to the secondary storage device is executed on each of the computers. A file management subsystem for giving an authority for writing the data to each access control subsystem, is executed on specified computer. When the file management subsystem transmits, to a certain access control subsystem, access control information indicating the authority for writing the data to a specified block on the secondary storage device, the same access control information is saved in the transmitted-side access control subsystem, and its record is retained in the file management subsystem. If the file management subsystem falls into a process-down, a standby file management subsystem is determined to become a new file management subsystem. Then this standby file management subsystem requests each of the access control subsystems to notify of the access control information saved by each of the access control subsystems.
