An Oracle Enterprise Manager administrative user is an account that provides users permission to perform administrative tasks and access administrative information. An administrative account is usually created for each person on an administrative team. Preferences, such as preferred credentials, login password, and email and paging notification schedules, must be set for each administrator. Generally each person has a single administrative user account through which he administers several to many targets.
Administrative user accounts are created by the super administrator. Oracle Enterprise Manager is installed with a default super administrator account which can be used for the initial login. The super administrator account is similar to root on UNIX or Administrator on Windows NT and is a user which cannot be deleted or renamed.
Administrator user accounts are specific to Oracle Enterprise Manager and are different than Oracle database users.
A set of additional pre-defined events that are included in Oracle Diagnostics Pack, Oracle Management Pack for Oracle Applications, and Oracle Management Pack for SAP R/3. These events provide advanced options for use with the Event Management System.

A set of one or more administrative tasks scheduled with the Oracle Enterprise Manager Job Scheduling System; runs on managed databases or other services.
The system through which jobs are scheduled from the Jobs pane of the Oracle Enterprise Manager Console.
A data management tool in DBA Management Pack that aids in transferring data from operating system files, such as text files, to an Oracle database.
A managed node is any machine that is being monitored by an Intelligent Agent that has been discovered by the Console.
Every service running on a managed node is a managed service or target. Multiple services (targets) can exist on a single machine (node).
An optional system management pack that is used with Oracle Enterprise Manager; a set of applications for monitoring and diagnosing the Oracle Applications environment and planning for future resource needs.
An optional system management pack that is used with Oracle Enterprise Manager; a set of applications for monitoring, diagnosing, and planning for future needs in the SAP R/3 environment.

The middle tier and the core of the Oracle Enterprise Manager framework. The Management Server provides administrative user accounts, processes management functions such as jobs and events, and manages the flow of information between the tiers.
As the number of nodes and managed services in your network increases or if the current Management Server is overloaded, you can add more Oracle Management Servers to the middle tier to share and balance the workload. These additional Management Servers provide fault-tolerance in the case where one Management Server becomes unavailable. All Management Servers administering the same set of managed nodes share a single Repository, which stores all system data, application data, and the state of managed nodes throughout the environment.
Oracle Expert:

The right to execute a particular Oracle Enterprise Manager command or SQL statement; a right granted to a database administrator by a Super Administrator, or to a database user by a database administrator.
An individualized summary of data specifying system privileges as well as limitations on system resources; assigned to each database administrator and database user.
A summary of information about a database or object that appears when you select a database or object in a tree view; can be used to view and change object properties; often contains multiple tabbed pages.
An application integrated with Oracle Enterprise Manager that enables an administrator to quickly set up, configure, and manage an Oracle Replication environment.
A set of database tables used as a back-end store for the middle-tier Oracle Management Server(s), and that can be located in any Oracle database; is shared by administrators and stores the state and history of registered events and scheduled jobs; also contains accounts of all administrators, including information such as administrator passwords and privileges; contains the current view of the network including all system data, application data, and information about the state of managed nodes.
An Enterprise Manager repository is owned by a database user. During repository creation a repository's user name is entered that will be used to create this database user. The name of the repository user will also be the name of this repository, and this name will be used throughout the network to identify all the objects in this repository. The name of the repository must be a unique schema name across the entire managed network.
If the repository user name and encrypted password are saved during repository creation, the Management Server uses them to login to the repository; if they are not saved, the Management Server prompts the user for a user name and password before it starts up.
A set of database privileges granted to a database administrator or database user.
Functionality in the DBA Management Pack that helps administrators manage database schema objects; helps administrators to create, alter, or drop database clusters, indexes, snapshots, tables, and views.
Functionality in the DBA Management Pack that helps administrators make changes to security parameters for database objects, users, and other administrators quickly and efficiently.
There are two types of discovery:
Without the Intelligent Agent discovery, there is no Console discovery. Both discoveries must be successful and must happen in the correct order for the services to appear in the Console Navigator.
When you use the Discovery Wizard in the Console, the Management Server contacts the Intelligent Agent installed on that node to discover the Oracle services installed on the node.
When the Intelligent Agent starts, it performs its service discovery by scanning the system for Oracle services to manage. The Intelligent Agent records the service discovery. When the Console requests a discovery of the node, the Intelligent Agent transmits the service discovery information it has detected to the Management Server.
The Management Server then places the new information in the repository, and updates the Console Navigator, displaying a view of all nodes and their respective services.
Service discovery allows administrators to run jobs and monitor for events on those nodes and allows the information to be centrally managed by the Consoles.
An application integrated with Oracle Enterprise Manager that enables administrators to analyze and tune spatial indexes on database data.
A tool in Oracle Tuning pack that analyzes and tunes problematic SQL statements that are causing the greatest impact on database performance.
A tool in the DBA Management Pack with which administrators can execute SQL and PL/SQL commands and store them as files to reuse at a later time.
