Jerzy Neyman,Elizabeth L. Scott two-phase locking was first stated in this context [EGLT76] (also see [Date83],[BeHG87],[GrRe92]). Two-phase locking simply requires that no locks be released before all locks are acquired,. but this scheme is susceptible to cascading aborts, since a transaction whose updates have been accessed by 作者: 河潭 時間: 2025-3-24 13:34 作者: Audiometry 時間: 2025-3-24 15:20

Thus it is important to understand how hardware resource contention affects the performance of transaction processing systems, before considering the effect of data contention.作者: obtuse 時間: 2025-3-27 11:04
Jerzy Neyman,Elizabeth L. Scott,[BeHG87],[GrRe92]. Only the analysis of strict two-phase locking is considered in this chapter, as is the case with almost all studies of standard locking performance (see Section 3.6 for exceptions). The lock holding time is then from the instant at which the lock is requested to transaction completion time.作者: tenosynovitis 時間: 2025-3-27 15:25
