In version 9i Oracle gave us external tables. These objects allow us to query data in OS files through SELECT statements. This is pretty cool. Even cooler, in 11.0.1.7 we can associate a shell script with an external table to generate its OS file. Check out Adrian Billington's article on listing files with the external table preprocessor in 11g. Your shell script is an ideal candidate for the preprocessor functionality.

If you need to know the contents of the directory now for whatever purpose you can simply SELECT from the external table. If you want to keep a permanent record of the file names you can issue an INSERT INTO ... SELECT * FROM external_table;. This statement could be run autonomically using a database job.
