Management Pack for Oracle GoldenGate (Oracle GoldenGate Director)

When you download management pack for oracle goldengate, you have two files, director server and director client.
Here is the brief information on each of them.

Oracle GoldenGate Director is a multi-tiered client-server application that enables the configuration and management of Oracle GoldenGate instances from a remote client.

Oracle GoldenGate instances
Each instance of an Oracle GoldenGate Manger process is identified within Oracle GoldenGate Director by the fully qualified domain name of the host, the port on which Manager is listening, and a user-defined data source name.
Because a Manager process is associated with a database, this combination is identified as a data source within the Oracle GoldenGate Director Client application.

Oracle GoldenGate Director Server
Oracle GoldenGate Director Server coordinates the management of Oracle GoldenGate instances. Oracle GoldenGate Director Server is installed as an Oracle Weblogic Server domain.
Oracle GoldenGate Director Server is composed of the following applications:
● The Oracle GoldenGate Director Server application, a collection of services that controls security, host information services, object modeling, diagramming,
consolidated event logging, and alert services.
● The Monitor Agent, a client to the Oracle GoldenGate hosts that establishes a dedicated session of GGSCI (GoldenGate Software Command Interface).
The connection is used to obtain process status and event information.

Oracle GoldenGate Director database
Oracle GoldenGate Director Server uses a database as a central repository to store information about users and groups, graphical diagrams created by users, consolidated events, and other information.
A user can log into any Oracle GoldenGate Director Client on any system and retrieve his or her own stored view of the network.

Oracle GoldenGate Director Client
Oracle GoldenGate Director Client is a client application of Oracle GoldenGate Director Server that provides a graphical user interface (GUI) for managing Oracle GoldenGate instances.
The client runs on any platform that supports Java and enables drag-and-drop manipulation, menus and toolbars, and other functionality expected of a desktop application.

Oracle GoldenGate Director Web
Oracle GoldenGate Director Web is a web application that is hosted within Oracle GoldenGate Director Server. It allows remote, browser-based monitoring and control of
Oracle GoldenGate instances without the need to install software on the client system.

Oracle GoldenGate Director Administrator
Oracle GoldenGate Director Administrator is a client of Oracle GoldenGate Director Server and is used for configuring Oracle GoldenGate Director Server itself. You can use it to add
or remove Oracle GoldenGate instances and users, and to manage the overall Oracle GoldenGate Director configuration.

So, in all, these components are all for user convinience and management pack is nothing but the combination of all above director tools which helps user to monitor and manage the goldengate.

You can refer to the admin guide for management pack on how and where to install the server and related client tools and to check how they are linked to each other.
