Does Active Data Guard include Golden Gate? I've been told that Active Data Guard incorporates Golden Gate as part of its technology stack.

Is Golden Gate usable directly from the Active Data Guard installation?
It's the other way around. Active Data Guard is included if you license GoldenGate on Oracle Database Enterprise Edition.

The GoldenGate product page on Oracle Technology Network states:


  The license for Oracle GoldenGate includes a full use license for
  Oracle Active Data Guard, and a full use license for XStream in the
  Oracle Database.
