How does the Lock Manager contribute to ensuring data integrity in DB2's architecture?
- Enforces concurrency control
- Manages database backups
- Optimizes database performance
- Processes SQL queries
The Lock Manager in DB2's architecture plays a crucial role in ensuring data integrity by enforcing concurrency control mechanisms. It coordinates the access to shared resources such as database objects by multiple transactions, ensuring that only one transaction can modify a particular resource at a time to prevent conflicts and maintain data consistency. This helps in preventing issues like data corruption or inconsistent results due to concurrent access.
