I have installed Oracle 10g xe from a deb file on linux, and then started to configure it using this terminal command
sudo /etc/init.d/oracle-xe configure
but after finishing configuration I forgot the password, so how can I reconfigure it again after reinstallation as now when I use the previous command I receive
Oracle Database 10g Express Edition is already configured
Thanks,
Remove /etc/sysconfig/oracle-xe
and then /etc/init.d/oracle-xe configure
