One possible log setting that you can make is activating or deactivating redo log management.
Deactivate redo log management only rarely and in special cases, and then only for a fixed period of time.
Redo log management is activated by default.
If you deactivate redo log management, and then reactivate it, you must then make a complete data backup.
When you deactivate redo log management, the Log Writer no longer writes any redo log entries to the log area. Disabling redo log management means that the log backup history is interrupted, so if a recovery is necessary, no log entries are available for this period. Minimize this security risk by keeping the period in which there is no active redo log management as short as possible.
This setting is useful, for example, when you are initializing a database instance.
You can activate or deactivate the redo log management in the ADMIN operational state of the database instance. Use the Database Manager GUI, for example, as described in Changing Log Settings (Configuration Wizard).
