Overview/Description
An Oracle database is divided into logical storage units called tablespaces. Oracle also provides Oracle-Managed Files (OMF), which eliminate the need for the DBA to directly manage the operating system files in the Oracle database. To access the database, a user must specify a valid database user account and successfully authenticate as required by that user account. What the user can execute once they are logged in is controlled by privileges granted to them, which can be system or object. Privileges can be better controlled by using roles and profiles, which control...

Some of these tasks include I/O performance tuning, file system, cluster file system, and raw device management, and data file movements and reorganizations. When ASM is used, an ASM instance is also used. The ASM instance allocates memory and uses the SGA differently than in a database instance. This course describes the ASM instance and how it works, and demonstrates how to manage it with various...
