Segments Page
Note: Available for Oracle 10g and later.
The Segments page displays information on database segments associated with specified waiting events.
The Segments page contains a single table, Segments related to the event, which shows segment details for the specified event. You can use these details to spot performance problems associated with individual segments, and so identify hot tables or indexes.
