Time to delete 10000 records

Question

i am putting a query to delete 10000 records but it is getting hanged in sqlplus and Toad. I was putting 4 conditions in the 'where' clause but then i made it into only 1 clause but still it is giving a feeling of getting hanged. The query is like :
delete from ppbs_inv_sim_serial where sim_serial_no between '899105203112085000' and '899105203112094999'
Please help in solving the doubt as it is urgent.
regards

As RAO said, you can check any locks before carry out the sentence. You can check if there is any lock with this
script:
col object_name format a20
col username format a10
col oracle_username format a10
col process format a15
col owner format a10
prompt ****************************************************************
prompt *** Object Lock Contention ***
prompt ****************************************************************
set pages 0
set linesize 150
select 'Date : '||to_char(sysdate,'DD/MM/YYYY')||' Time : '||to_char(sysdate,'HH:MI:SS') from dual;
select 'Database Name : '||name from sys.v_$database;
set pages 1000
SELECT DISTINCT
O.OBJECT_NAME,
SH.USERNAME,
SH.SID,
SW.USERNAME,
SW.SID,
DECODE(LH.LMODE,
1, 'null',
2, 'row share',
3, 'row exclusive',
4, 'share',
5, 'share row exclusive',
6, 'exclusive')
FROM DBA_OBJECTS O,
V$SESSION SW,
V$LOCK LW,
V$SESSION SH,
V$LOCK LH
WHERE LH.ID1 = O.OBJECT_ID
AND LH.ID1 = LW.ID1
AND SH.SID = LH.SID
AND SW.SID = LW.SID
AND SH.LOCKWAIT IS NULL
AND SW.LOCKWAIT IS NOT NULL
AND LH.TYPE = 'TM'
AND LW.TYPE = 'TM'
prompt Press Enter to continue ...
