6.6 Defining Oracle Enterprise Manager Administration Roles

In 11g Release 1 (11.1.1), Oracle Enterprise Manager supports three kinds of administration roles: Administrator, Operator and Monitor. An Administrator role has full privilege for performing any operations, including security-related operations. Whereas, an Operator has a few privileges and the monitor has a limited set of privileges. If a user doesn't have permission, the functionality is either invisible or greyed out.
