Hmm bei mir macht er es :

los-web:/ # sqlplus /nolog
SQL> conn system@xe
Enter password:
Connected.
SQL> @$ORACLE_HOME/rdbms/admin/utlsampl.sql
Disconnected from Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Beta

los-web:/ # sqlplus /nolog
SQL> conn system@xe
Enter password:
Connected.

SQL> select username from dba_users where username='SCOTT';

USERNAME
------------------------------
SCOTT

SQL>
SQL> conn scott/tiger
Connected.
SQL>

Versuchs mal nochmal ;-)
