Database server activity that is physically logged

If multiple modifications were made to a page between checkpoints, typically only the first before-image is logged in the physical log.

The physical log is a cyclical log in which the pages within the physical log are used once per checkpoint. If the RTO_SERVER_RESTART configuration parameter is set, additional physical logging occurs to improve fast recovery performance.
