The error messages will be in unix mail for the owner of the cron.

The default environment for cron is very limited. Any extra environment which has been set for whichever interactive user ran the script successfully needs to be put into the script if you want it to work from cron.

In your case I doubt if "exp" is in $PATH and also there are no ORA environment variables set.

Try running "set" from the command line and compare with the output of a one-off cron containing just "set".
