You can configure a session to use IBM DB2, Oracle, Sybase IQ, and Teradata external loaders to load session target files into their respective databases. External loaders can increase session performance by loading information directly from a file or pipe rather than running the SQL commands to insert the same data into the database.
Use multiple external loaders within one session. For example, if a mapping contains two targets, you can create a session that uses an Oracle external loader connection and a Sybase IQ external loader connection.
