How to reconfigure Oracle 10g xe on Linux

Remove /etc/sysconfig/oracle-xe
and then /etc/init.d/oracle-xe configure

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

CONFIGURE_RUN=false

and rerun

sudo /etc/init.d/oracle-xe configure

linux oracle oracle10g

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
