What is lock escalation?



What is lock escalation?..

Answer / swapna

Lock escalation is the process of converting a lot of low
level locks (like row locks, page locks) into higher level
locks (like table locks). Every lock is a memory structure
too many locks would mean, more memory being occupied by
locks.

To prevent this from happening, SQL Server escalates the
many fine-grain locks to fewer coarse-grain locks. Lock
escalation threshold was definable in SQL Server 6.5, but
from SQL Server 7.0 onwards it's dynamically managed by SQL
Server.
