Rem    NOTES
Rem      This script must be run while connected as a user with DBA privileges.
Rem      In case of directory users, new users reside in the same directory
Rem      information tree as existing users and database account equals to
Rem      directory account.
Rem      This script does not completely clone user SYS.
Rem      This script has been tested successfully against the following
Rem      Oracle Server version(s):
Rem        - Oracle Server 10g Release 1;
