dbdbd: problem with accessHi guys,

To begin with sorry for my bad English

I use dbdbd for my project:
..
db = DBDB.new("%7c%1c%2c%")
#db.uniq_key = 2
db.tie(file_name)
db.read
..

In the end I need to delete file that I use.
But "File.delete(file_name)" or "File.unlink(file_name)"
It shows:
"Permission denied - AS400_IMPORT/WDB.X105070727"

Does anyone know how can I finish work with dbdbd file?

Thanks
