Restoring an OSCAR dump file only restores the database "oscar" and does change any password thing in "mysql" database. Anyways, like I said, a user who knows the root password of mysql can update the OSCAR database password accordingly anytime. So, I would not need to backup/restore /etc/odapw but would like to find a way to manage the root password safely instead. But there was my bad understanding. emptying /etc/odapw may not re-generate oscar database properly.
