The log mode is a log setting. It determines whether the log area is mirrored using software-based mirroring or not.
Use this setting if hardware-based mirroring cannot be used to secure your database against data loss in the event of crashes. Since software-based mirroring reduces the performance of your database system, we recommend that you use hardware-based mirroring.
