摘要： Provided are a method and a system for managing a file metadata, which are independent of a address change of a data server and movements of a disk by using a location of disk where data exists actually as a location information of a file data. The method for managing the file metadata includes determining whether the request of the metadata is valid, verifying information of a disk storing a file data corresponding to the metadata and a data server address in which the file data exists, and transmitting the verified address of the data server to the client. According to the method and the system for managing the file metadata, data services can be continuously provided without modifications of a file metadata even if the data server address is changed.

摘要： Provided are a file storage system, and a method for managing duplicate files in the file storage system. The file storage system that performs file duplication for error recovery includes a client for requesting generation of a duplicate file of a new file being stored, a metadata server for storing information associated with prestored duplicate files and determining whether a file that is identical to the new file is present among the prestored duplicate files, to limit a number of identical duplicate files to a preset number, and a data server comprising a file duplication unit and a storage unit for respectively performing file duplication and file storage under the control of the metadata server. Accordingly, file recovery can be performed while duplicate files in the system are minimized.

摘要： A method for file deletion and recovery against system failures in a database management system comprising steps of deleting files listed in a pending action list during a transaction commit process, writing a non-atomic file deletion as an atomic operation into a log and recovering uncompleted file deletion during restart recovery by using the log is disclosed. When system failures occur during file deletion in a database management system, resources of which releasing is interrupted by failures are released perfectly through recovery step, so it is advantageous in that coherency of data is maintained and efficiency of storage device arises.

摘要： A cache consistency maintenance procedure to select one of a detection-based cache consistency maintenance procedure optimized for record-based locking and an avoidance-based consistency-based maintenance procedure optimized for table and block-based locking. To support the characteristic of DBMS in which table locking and record locking are consistent to access the same table, the two kinds of the consistency maintenance policies for the same block are processed by a single buffer load process and the two kinds of the consistency maintenance policies are consistent with each other to provide better configuration and performance.
