Caution

Do not switch redo log management off in normal database operation. When redo management is switched off, the system does not write regular savepoints. This means that if you restart your database after a database crash, you lose all data since the last savepoint. If you have to restore your database, you can only restore it to the state of the last data backup.

Only consider switching redo log management off in special situations, for example in a test system or during a large load job.
