You must run '/etc/init.d/oracle-xe configure' as the root user to configure the database.

[root@vmcx-43 Disk1]# /etc/init.d/oracle-xe configure

Oracle Database 11g Express Edition Configuration
-------------------------------------------------
This will configure on-boot properties of Oracle Database 11g Express
Edition.  The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts.  Press <Enter> to accept the defaults.
Ctrl-C will abort.

Specify the HTTP port that will be used for Oracle Application Express [8080]:

Specify a port that will be used for the database listener [1521]:

Specify a password to be used for database accounts.  Note that the same
password will be used for SYS and SYSTEM.  Oracle recommends the use of
different passwords for each database account.  This can be done after
initial configuration:
Password can't be null. Enter password:
Password can't be null. Enter password:
Confirm the password:

Answer 1

Add your servers name and IP to the /etc/hosts file

Answer 2

I had same issues.

I uninstalled oracle-xe. See How to reconfigure Oracle 10g xe on Linux

Then followed

yum install bc
rpm -i oracle-xe.rpm
/etc/init.d/oracle-xe configure

Everything went fine.
