How does DB2 handle data integrity issues caused by concurrent transactions?
- DB2 automatically aborts one of the conflicting transactions to resolve data integrity issues.
- DB2 creates duplicate copies of conflicting data to prevent data integrity violations.
- DB2 ignores data integrity issues caused by concurrent transactions and allows inconsistent results.
- DB2 resolves data integrity issues by using locks to control access to shared resources during concurrent transactions.
DB2 employs various concurrency control mechanisms, such as locking and isolation levels, to manage data integrity issues arising from concurrent transactions. By using locks, DB2 ensures that only one transaction can access a specific resource at a time, preventing conflicting updates and maintaining data consistency. Additionally, DB2 supports different isolation levels, allowing users to control the visibility of changes made by concurrent transactions to address consistency requirements.
