Method for file deletion and recovery against system failures in database management system
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.
