Oracle Alert DBA Alerts
Oracle Alert Database Administration (DBA) alerts help you manage your database by notifying you regularly of:
- Tables and indexes unable to allocate another extent
- Users who are nearing their tablespace quota
- Tablespaces without adequate free space
- Tables and indexes that are too large or are fragmented
- Tables and indexes that are near their maximum extents
If Oracle Alert finds the database exceptions specified in a DBA alert, it sends you a message summarizing all exceptions found. If Oracle Alert finds no exceptions, it sends you a message reporting that no exceptions were found. Oracle Alert keeps you notified of the status of your database, even if it is unchanging.
The Applications DBA application owns the Oracle Alert DBA alerts. This lets Oracle Alert perform the DBA alerts for every database instance you create, even those that reside outside Oracle Alert's database.
The following descriptions list the customizable frequency and inputs of each DBA alert.
