Redo log management is the part of the database software that manages redo log entries. You can switch redo log management off.
Do not switch redo log management off in normal database operation, because with restarting your database after a database crash, you lose all data since the last savepoint.
Only consider switching redo log management off in special situations, for example in a test system or during a large load job.
