Registering an Extract is required for change synchronization for Oracle and PostgreSQL databases.

This topic describes registering an Extract from the Admin Client. You can also register an Extract from the web interface while creating the Extract. See Add an Online Extract to see the steps to register an Extract from the web interface.

In case you need to upgrade Oracle GoldenGate and the installation directory for the Extract process is different, you need to use the MIGRATE option with the REGISTER EXTRACT command in Admin Client. See REGISTER EXTRACT in the Command Line Interface Reference for Oracle GoldenGate to know more.
