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,
回答1:
Oracle creates a system account named oracle. To change password to that account just use
passwd oracle
if you forgot another password from DB then log in as oracle user and use
sqlplus / as sysdba
to change the password for various DB accounts.
To reconfigure change in /etc/default/oracle-xe
CONFIGURE_RUN=true
to
CONFIGURE_RUN=false
and rerun
sudo /etc/init.d/oracle-xe configure
回答2:
Remove /etc/sysconfig/oracle-xe
and then /etc/init.d/oracle-xe configure
回答3:
The problem is solved... While removing the oracle I used
sudo apt-get remove oracle-xe-universal
and then remove the configurations using
sudo rm -rf /usr/lib/oracle
but these commands don't remove the configurations completely, the solution is to remove the oracle-xe-universal from Synaptic Manager and mark for Complete Removal.
Then install oracle-xe-universal again from the deb file then configure it.
Thanks,

In my case (Oracle XE 18c on Ubuntu), I had to remove the last line from /etc/oratab
回答5:
For Oracle XE 18c on Oracle Linux (7.7 in this case), the installation can be restarted by executing the following command as root:
/etc/init.d/oracle-xe-18c delete
Restart the installation with the same command that was issued initially:
/etc/init.d/oracle-xe-18c configure
