We are loading data into an Oracle table, using an external table to define the source data file stored on our LINUX machine. When we run the script from SQLPlus to load the data, a log file is created in the same directory as the data file, owned by the Oracle user.

Out LINUX admin is wary of the fact that someone who is authenticated as themselves on the database, can create a file owned by the Oracle user on the server. Is there a way to force a different owner on this logfile, or can you describe if this a risky by-product of this process that we should worry about, or do you have an alternate method which still uses an external table?
