  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:
