Using Oracle Enterprise Manager

Oracle Enterprise Manager is a web-based GUI for managing Oracle databases. You can use this GUI to perform a variety of administrative tasks such as creating tablespaces, tables, and indexes; managing user security; and backing up and recovering your database. You can also use Oracle Enterprise Manager to view performance and status information about your database instance.

From Oracle Enterprise Manager, you can view storage mapping information and a graphical display of the storage layout. Storage mapping information cannot be viewed with the Oracle 10g version of the Oracle Enterprise Manager client. However, the Oracle9i version of Oracle Enterprise Manager can be used with Oracle 10g to view storage mapping information.

For more information about Oracle Enterprise Manager, refer to your Oracle documentation.

 To view storage information

2. Expand the Databases icon and select the desired database.

   The Database Connect Information window appears.

3. Enter a user name and password to log in to the database and click OK.
4. In the object tree, expand the Storage icon.
5. Under the Storage icon, expand the Datafiles icon.

   Within the Oracle Enterprise Manager Console, you can point to an object on the screen and a description of the object is displayed in a pop-up field. If an object name or path appears truncated, point to it and the pop-up field will display the full object name and path.
