Components of Oracle GoldenGate Classic Architecture

You can use the Oracle GoldenGate Classic Architecture to configure and manage your data replications from the command line.

• What is a Manager?
  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.

• What is a Data Pump?
  Data pump is a secondary Extract group within the source Oracle GoldenGate configuration.

• What is a Collector?
  The Collector is started by the manager process and is a process that runs in the background on the target system. It reassembles the transactional data into a target trail.

• What is GGSCI?
  You can use the Oracle GoldenGate Software Command Interface (GGSCI) commands to create data replications. This is the command interface between you and Oracle GoldenGate functional components.
