Which lock is a default locking mechanism in oracle?

The default locking mechanism in Oracle is called Enqueue Lock. This lock mechanism is used to control concurrent access to database resources. It is automatically managed by Oracle itself and is used to prevent destructive interference of simultaneous conflicting transactions. It ensures data integrity and consistency by protecting areas of the database from destructive interference.

The default locking mechanism in Oracle is called "Enqueue Lock". This lock mechanism is automatically managed by Oracle itself and is used to control concurrent access to database resources. It is a sophisticated lock mechanism that allows different transactions to lock different resources in different modes, to maximize the concurrency of transactions while ensuring data integrity.
