"If only the after images are being journaled for a database file when that file is opened under commitment control, the system automatically starts journaling both the before and after images. The before images are written only for changes to the file that occur under commitment control. If other changes that are not under commitment control occur to the file at the same time, only after-images are written for those changes."
