How to reconfigure Oracle 10g xe on Linux

Question

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

Answer 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
