Oracle GoldenGate 11gR2 New Feature: Integrated Capture

With the release of Oracle GoldenGate 11gR2, the Product Management team is very excited about the addition of Integrated Capture for the Oracle platform. Integrated capture is unique in the industry and unique to the Oracle database. It is not available on any other database platform. This new feature moves GoldenGate’s capture capabilities closer to the Oracle Database engine and is the foundation for Oracle GoldenGate on the Oracle Database platform over the long term.

It is important to note that Integrated Capture does not replace our classic Capture process. Both are available on the Oracle Database platform.

The Integrated Capture mechanism relies on Oracle’s internal log parsing and processing to capture DML transactions. By moving closer to the Oracle Database engine, Oracle GoldenGate can take advantage of new Oracle Database features and functionality more quickly.

For example, this new mechanism allows GoldenGate to support advanced features such as compression. Integrated Capture provides support for all flavors of Oracle compression, including hybrid columnar compression (EHCC) on Exadata, where as our “Classic” capture would not.

Integrated Capture supports two different deployment configurations; On-Source and Downstream.

The on-source deployment model is what most customers are familiar with. Oracle GoldenGate is executing on the database server capturing changes in real time. This is the default deployment method.

The other option is downstream, where the source database and the Oracle GoldenGate Capture process are on different machines. This method effectively off-loads the processing requirements to a second machine.

Customers may choose which option they prefer based on their requirements.

 

Additional information on Integrated Capture can be found in our documentation and the white paper “Oracle GoldenGate for Oracle”.
