Remove DBMS_LOCK Locks

10gR2

there're many many records in "dbms_lock_allocated" from my previous testing, and I recognize the names
I know they're useless now

If they can/should be removed, how to do it ?

DBMS_LOCK.RELEASE(<lockid>) ;
returns " Parameter error"

SQL> desc sys.dbms_lock_allocated
Name Type Nullable Default Comments ---------- ------------- -------- ------- --------

NAME       VARCHAR2(128)
LOCKID     INTEGER       Y
EXPIRATION DATE          Y
