Oracle Database 10g Express Edition Configuration
-------------------------------------------------
This will configure on-boot properties of Oracle Database 10g 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:
Confirm the password:

# ps -afe|grep oracle
oracle 10500 1 0 21:23 ? 00:00:00 /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/tnslsnr LISTENER -inherit

So, I have found listener.ora and /tnsnames.ora in /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/network/admin/samples/ and I can copy this files to thhe good location but no postDBCreation.sql found on my computer

So what's wrong ? is this file really missing ?
thanks for your tips
