Con la siguiente consulta vemos los objetos bloqueados y que usuario los tiene.
Ejecutar la consulta con el usuario "system"
select a.session_id,a.oracle_username, a.os_user_name, b.owner "OBJECT OWNER", b.object_name,b.object_type,a.locked_mode from
(select object_id, SESSION_ID, ORACLE_USERNAME, OS_USER_NAME, LOCKED_MODE from v$locked_object) a,
(select object_id, owner, object_name,object_type from dba_objects) b
where a.object_id=b.object_id
y con la siguiente consulta vemos las sessiones que tienen bloqueados objetos:
SELECT l.session_id||','||v.serial# sid_serial,
l.ORACLE_USERNAME ora_user,

FROM dba_objects o, gv$locked_object l, v$session v
WHERE o.object_id = l.object_id
and l.SESSION_ID=v.sid
order by 2,3;
con los datos que nos arroja podemos realizar un kill seesion.
