Zusammenfassung: | A rollback record may be created for each step identifier (ID). The rollback record indicates how many times the step record identified by the step ID has been rolled back during operation of the database. The rollback record may be stored in a periodic save record (PSR), separate from or stored in an audit trail containing the step records. By processing the rollback records in the periodic save record during a recovery, a database may identify a time on an audit trail for initiating a recovery prior to the last resume point for a step without going back in the audit trail to a time before the initial start of the step. |
