SQL & PL/SQL

I would likle to use Hierarchical Profiler. In order to use it, I have to execute below script. However, I couln't find it anywhere. I searched DBMS_HPROF package in all_objects table, it exists in db. Do you have any idea how can I execute this script? If it is not exist in my computer can I download it anywhere?

Note: I use windows 7

@$ORACLE_HOME/rdbms/admin/dbmshptab.sql

select * from all_objects where object_name = 'DBMS_HPROF';

SYS	DBMS_HPROF		10581		PACKAGE BODY	01/11/2007	01/11/2007	2007-11-01:21:00:04	VALID	N
