SQL*Loader control files for importing into Oracle database

Hi,

I've been working with Informix for the last 6 or more years and now have to help porting an application to ORACLE.

We have a lot of generators for Informix written in awk etc. and now need something to automate the creation of SQL*Loader control files for importing data into Oracle databases when the database schema exists already.

Does such a (small ?) tool exist already, and when yes could you please give me any pointer to it?

Thank you,
Klaus Rehm
