What are exclusive locks in database management?
Exclusive locks are used to prevent other transactions from accessing the same resource. They ensure that only one transaction can modify a resource at a time.
How do exclusive locks differ from shared locks?
Exclusive locks allow only one transaction to modify a resource, while shared locks allow multiple transactions to read a resource simultaneously.
Can you give me an example of when to use an exclusive lock?
Sure! You would use an exclusive lock when updating a record in a database to ensure no other transaction can read or write to that record until the update is complete.
What happens if a transaction holding an exclusive lock fails?
If a transaction holding an exclusive lock fails, the lock is released, allowing other transactions to access the resource.
