Setting Up Enterprise Manager Preferences

Learn Oracle - Setting Up Enterprise Manager Preferences

Enterprise manager enables Oracle DBA to set up preferences that help Oracle DBA manage the database. These include the following:

Notification---These are settings that enable Oracle to email Oracle DBA alert notifications. Alerts are notifications of when a database is in an undesirable state and needs your attention. By default, the Enterprise Manager home page lists all alerts. However, set up is required for email notification.

Blackout Administration---When Oracle DBA have planned downtime for database maintenance, you can indicate to Oracle that you do not want false alerts to be sent to you. To do so, you define a black out period. See Defining Blackout Time Periods in this section.



Preferred Credentials---Enterprise Manager can automatically execute many routine administrative tasks, such as backups on your behalf. This is done using sophisticated job scheduling system built into the Enterprise. To keep your environment secure, setting up tasks for automatic execution in Enterprise Manger requires Oracle DBA to provide login information for the machine and database. In order to avoid having to enter this information every time Oracle DBA create a job or task, Enterprise Manager enables Oracle DBA to save this information as preferred credentials. Preferred credentials are stored in the database in encrypted mode to protect it from unauthorized use. See Setting Preferred Credentials in this section.
