Enterprise Manager Database Express in Database 12c Release 1

Introduction


Key things to remember about Enterprise Manager Database Express.

◈ EM DB Express is not a replacement for the DB Control from 11g, as it has significantly less functionality.
◈ A DBA will not be able to administer the database using just EM DB Express.
