Manager is the control process of Oracle GoldenGate. Manager must be running on each system in the Oracle GoldenGate configuration before the Extract or Replicat processes can be started.

Manager must also remain running while the Extract and Replicat processes are running so that resource management functions are performed. One Manager process can control many Extract or Replicat processes.

Manager performs the following functions:

• Starts Oracle GoldenGate processes

• Starts dynamic processes

• Maintains port numbers for processes

• Purges Trail files based on retention rules

• Creates event, error, and threshold reports

One Manager process can control many Extract or Replicat processes. On Windows systems, Manager can run as a service. See Configure the Manager Process for more information about the Manager process and configuring TCP/IP connections.
