In COBOL, what mechanisms or techniques can be employed to optimize file locking strategies for high-performance multi-user systems?
- Implementing complex locking algorithms without considering transaction boundaries
- Implementing record-level locking, choosing appropriate lock modes, and using transaction management to minimize lock duration
- Locking only during write operations and not during read operations
- Using file-level locking for simplicity, avoiding locking altogether, relying on database management system locks
To optimize file locking in COBOL for high-performance multi-user systems, employ mechanisms like record-level locking, choose suitable lock modes, and use transaction management to minimize lock duration. This ensures efficient concurrency while maintaining data integrity.
