file locking mechanism restricts access computer file region file allowing one user process modify delete specific time prevent reading file modified deleted.systems implement locking prevent classic interceding update scenario typical example race condition enforcing serialization update processes given file.following example illustrates interceding update problem process reads customer record file containing account information including customers account balance phone number.process b reads record file copy.process changes account balance copy customer record writes record back file.process b still original stale value account balance copy customer record updates account balance writes customer record back file.

process b written stale accountbalance value file causing changes made process lost.most operating systems support concept record locking means individual records within given file may locked thereby increasing number concurrent update processes.database maintenance uses file locking whereby serialize access entire physical file underlying database.although prevent process accessing file efficient individually locking many regions file removing overhead acquiring releasing lock.poor use file locks like computer lock result poor performance deadlocks.file locking may also refer additional security applied computer user either using windows security ntfs permissions installing third party file locking software.computer writer gary b. shelly notes many wiki systems block contributor attempting edit page able contributor currently editing page saves changes remains idle page extended period time.merge determining edits unrelated parts file combining without user intervention.
