Answer:Oracle GoldenGate supports active-active configurations for Oracle Database, DB2 on z/OS, LUW, and IBM i, MySQL, SQL/MX,SQL Server, and Sybase. However, the setup is different from database to database. After GoldenGate 12.1.2, Teradata capture is not supported by Oracle GoldenGate. Therefore, there is no active-active replication support.
