10.1 Overview of the Manager Process

To configure and run Oracle GoldenGate, a Manager process must be running on all Oracle GoldenGate source and target systems, and any intermediary systems if used in your configuration. Manager is the controller process that instantiates the Oracle GoldenGate processes, allocates port numbers, and performs file maintenance. Together, the Manager process and its child processes, and their related programs and files comprise an Oracle GoldenGate instance. The Manager process performs the following functions:

• Starts Oracle GoldenGate processes

• Starts dynamic processes

• Starts the Collector process

• Manages the port numbers for processes. (All Oracle GoldenGate ports are configurable.)

• Performs trail management

• Creates event, error, and threshold reports

There is one Manager per Oracle GoldenGate installation. One Manager can support multiple Oracle GoldenGate extraction and replication processes.
