Shouts: Shouts are alerts that relate to job processing problems and you can define their settings in the Shout Destination Manager. For more information, see Shout destination management.
Exception alerts: Alerts that notify you of system failures in the database, communication network, and application errors and failures. You can handle these exception alerts as necessary in the Exception Alerts window. The Exception Alerts window displays information about each alert, such as the alert ID, severity of the alert, the message that was generated by the alert, and more. For more information, see Managing exception alerts.
Alerts are deleted automatically after they reach the threshold in the database. You can also delete alerts manually if necessary,(example: low disk space), as described in Removing old alerts.
