Add TRANDATA
Valid for Db2 i, Db2 LUW, Db2 z/OS, Oracle, PostgreSQL, SQL Server, and Sybase.
Depending on the source database, supplemental logging must be enabled to capture DML
                operations and can be enabled through the Trandata menu of a database
                connection in the web interface, or in the Admin Client by issuing ADD TRANDATA or ADD SCHEMATRANDATA (for Oracle only).
                  
Adding TRANDATA is not required on a source database for
                an initial load Extract. However, if both initial load Extract and change data
                capture (CDC) Extract will be used in conjunction, for an online instantiation, then
                    TRANDATA should be added prior to starting the initial load
                Extract.
