Your team is encountering record locking issues when multiple users are simultaneously accessing a VSAM indexed file. How would you implement file locking strategies to address this problem?
- Option 1: Implementing shared locks for all users
- Option 2: Using exclusive locks for all transactions
- Option 3: Employing a combination of shared and exclusive locks strategically
- Option 4: Avoiding locks altogether for seamless access
Employing a combination of shared and exclusive locks strategically is the preferred approach. Shared locks allow multiple users to read the file simultaneously, while exclusive locks ensure exclusive access for write operations, minimizing conflicts and ensuring data integrity in a multi-user environment.
