Scenario: A critical application relies on accurate data stored in a DB2 database. How can the DBA ensure continuous data integrity while handling frequent updates and transactions?
- Implementing concurrency control mechanisms such as locking and isolation levels
- Utilizing database logging to maintain a record of all changes made to the data
- Regularly performing database backups to recover from data corruption or loss
- Employing online reorganization utilities to optimize database performance
Option 2: Utilizing database logging ensures that a record of all changes made to the data is maintained. In the event of a failure or integrity violation, DBAs can use database logs to trace back changes and restore the database to a consistent state. This method ensures continuous data integrity even during frequent updates and transactions.
