Enabling the database to save key events stores a streamlined account of the information written to the database log file within the database in the _KeyEvt table. Saving key events can provide the database administrator or a Progress technical support engineer, an efficient record of critical events in the history of the database. When the database is enabled to save key events, an additional background database process is created to periodically scan the database log file, creating records of the key events in the _KeyEvt table. For more information on key events, see Manage the OpenEdge Database.
