Oracle Exadata Database Machine has already been mentioned in this chapter. The Oracle engineered solution, depending on its configuration, features a number of Oracle database servers configured for RAC, offering high parallel processing on Exadata storage cells along with high speed Infiniband network interfaces. The environment also supports GoldenGate, enabling real-time data integration.

Depending on the machine size, the database servers and storage cells can be configured in a number of ways to provide more than one RAC cluster. If your source and target database reside in the same database machine, there is no need to configure a data pump process. Data can be transmitted directly from Extract to Replicat at very high speeds. This applies to Exadata and nonExadata environments.
