Capturing using a MySQL Replication Slave

You can configure a MySQL replication slave to capture the master's binary log events from the slave.

Typically, the transactions applied by the slave are logged into the relay logs and not into the slave's binlog. For the slave to write transactions in its binlog, that it receives from the master , you must start the replication slave with the log-slave-updates option as 1 in my.cnf in conjunction with the other binary logging parameters for Oracle GoldenGate. After the master's transactions are in the slave's binlog , you can set up a regular Oracle GoldenGate capture on the slave to capture and process the slave's binlog.
