Aprašymas

File locking is a mechanism that restricts access to a computer file by only allowing one user or process access at any specific time. The purpose of locking is to prevent the classic interceding update scenario. File locking prevents this problem by enforcing the serialization of update processes to any given file. Most operating systems support the concept of record locking which means that individual records within any given file may be locked, so increasing the number of concurrent update processes. One use of file locking is in database maintenance where it can serialize access to the entire physical file underlying a database. While this prevents any other process from accessing the file it can actually be more efficient than individually locking a large number of regions in the file by removing the overhead of achieving and releasing each lock.
