What is an exclusive lock?
An exclusive lock is a type of lock that prevents other transactions from accessing a resource while it is being modified. When an exclusive lock is held on a database object, no other transaction can acquire any type of lock (exclusive or shared) on that object until the exclusive lock is released. This mechanism ensures data integrity and consistency during operations that require exclusive access. Exclusive locks are typically used during write operations to prevent conflicts.
What are the various types of locks used for concurrency control?
Concurrency control employs various types of locks to manage access to shared resources, ensuring data integrity. The primary types include shared locks, which allow multiple transactions to read a resource but prevent writing, and exclusive locks, which permit only one transaction to read or write a resource. Additionally, read locks and write locks can be used to differentiate between operations, while optimistic and pessimistic locking strategies determine when locks are applied based on expected contention levels. Each type of lock addresses different concurrency scenarios, balancing performance and data consistency.
