I second Jared's recommendation for using external tables. you can use them
in parallel if large files can be split into multiple. Plus you can use the
magic of SQL to do necesasary transformation as well.
I have had great success with them. In once case the preferred ETL tool
couldn't do the job properly for a 6m-20m rows file in allotted time. We
managed to split the file into pieces, used parallel processing (one thread
for each file piece) for a single external table, and then use
dbms_errorlog to capture invalid data while loading into staging tables.
