11 Using GoldenGate as an Alternative to Native Read-Only Cache Groups

Oracle GoldenGate is Oracle's primary data replication and data exchange technology. GoldenGate supports a multitude of databases as sources for data capture as well as targets for data delivery.

TimesTen can be deployed in several ways, including as an in-memory cache for data that resides in an Oracle database. TimesTen provides functionality to enable it to act as a native cache for Oracle database. This technology supports both read-only and read-write caching.

If your caching use case provides read-only caching, you may prefer to use GoldenGate to refresh data from the backend database to the TimesTen cache, instead of using the TimesTen native cache functionality.
