You shouldn't be modifying /etc/crontab. Instead use "crontab -e". The explains why "crontab -l" does not show anything. You should preferably use "crontab -e" from the oracle account in which case you don't need a user name after the time fields. Review the following links: Also, your "rm" command line is malformed. You probably meant to use "&&" (command concatentation) not "&" (background mode). Review the following link. Iggy
