PRAGMA AUTONOMOUS_TRANSACTION in ORACLE PLSQL - Use case
- In the airline industry's cargo management system, autonomous transactions can play a critical role in ensuring the integrity and consistency of operations without affecting the main transactional flow.
- During operations there are auxiliary tasks for logging, auditing, or updating external systems, which should occur independently of the main transaction that handles cargo updates.
- An example of booking cargo, updating cargo status in main and logging of such status is being described.
- For such cases of asynchronous operations, PRAGMA AUTONOMOUS_TRANSACTION can be used.
- The autonomous transaction should execute independent of the main transaction and even if any failure occurs, it should not restrict successful execution of main transaction.
- This approach helps in maintaining transactional integrity, separating concerns and compliance.
- PL/SQL code example is provided to understand the use of PRAGMA AUTONOMOUS_TRANSACTION.
- Overall, the approach ensures that the logging process occurs independently for the audit trail purpose.
- It also minimizes disruption to the core functionality of the system.
- This can be used in any systems like cargo management, asset management, etc.
