insert statement runs slow

Hi,Buddy:

DB VERSION: 10.1.0.2.0
Now i meet such situation: table and index analyzed every midnight, and the biggest table REQDTF has 3893353 rows.when i running such statement, it executed 0.27 second.

2:27:53 SQL> select count(*) from reqdtf;

COUNT(*)
----------
3893353

Executed in 0.27 seconds

02:28:00 SQL>
other tables have only 100000 rows data.REQDTF_AVL_TEMP will be truncated everyday before insert.

my problem is when i insert REQDTF_AVL_TEMP table, it cost 20 minute, all index are used. so i want to speed up this statement.for 20 minutes can't bear.thanks for you aiding.

INSERT /*+noappend*/ INTO REQDTF_AVL_TEMP ( FPMODRFLG , FOYAODRNO ,FOYAODRNO2 ,FREQSEQNO, FSTRSEQNO, FKOITEMNO ,FLOTNO ,FLOTNO2, FKOWHCD ,FKOLCTCD ,FREQDTE ,FFIRMREQ , FSTRUUNIT , FISSWAY , FISSTTL , FNOREQQTY , FREQDTFLG,FPRJNO , FITEMNO , FMFGODRSTS , FMOISSFLG , FOYAITEM_FUNIT , FMFGODRQTY, FITEMTYP , FPASTFLG ,FITMCNVTYP , FUNEXCHG , FKOITEM_FUNIT ) SELECT REQDTF.FPMODRFLG,REQDTF.FOYAODRNO,REQDTF.FOYAODRNO2,REQDTF.FREQSEQNO,REQDTF.FSTRSEQNO,REQDTF.FKOITEMNO,REQDTF.FLOTNO,REQDTF.FLOTNO2,R EQDTF.FKOWHCD, REQDTF.FKOLCTCD, CASE WHEN REQDTF.FREQDTE <= :B7 THEN :B7 ELSE REQDTF.FREQDTE END , REQDTF.FFIRMREQ, REQDTF.FUUNIT, REQDTF.FISSWAY, DECODE(REQDTF.FFIRMREQ,0,DECODE(REQDTF.FSPAREITEM,REQDTF.FKOITEMNO,REQDTF.FISSTTL,LEAST(REQDTF.FISSTTL,REQDTF.FFIRMREQ)),REQDTF.FISST TL) REQDTF_FISSTTL, REQDTF.FNOREQQTY,REQDTF.FREQDTFLG,MORLSF.FPRJNO,MORLSF.FITEMNO,MORLSF.FMFGODRSTS,MORLSF.FMOISSFLG,ITEMM_A.FUNIT,MORLSF.FMFGODRQTY,ITE MM_A.FITEMTYP, CASE WHEN REQDTF.FREQDTE <= :B7 THEN 'Y' ELSE 'N' END, ITEMM_B.FITMCNVTYP, 1, ITEMM_B.FUNIT FROM MORLSF,REQDTF,ITEMM ITEMM_A,ITEMM ITEMM_B WHERE ( MORLSF.FMFGODRSTS <> 'C' ) AND ( MORLSF.FMFGODRSTS <> 'H' ) AND ( REQDTF.FREQDTE <= :B6 ) AND ( FFIRMREQ - FISSTTL - FNOREQQTY > 0 ) AND ( MORLSF.FMFGODRSTS <> :B5 ) AND ( MORLSF.FITEMNO = ITEMM_A.FITEMNO ) AND ( REQDTF.FOYAODRNO = MORLSF.FMFGODRNO ) AND ( REQDTF.FPMODRFLG = 'M' ) AND ( REQDTF.FPMODRFLG = MORLSF.FPMODRFLG ) AND ( RTRIM(REQDTF.FKOITEMNO) LIKE RTRIM(:B4 ) ) AND ( RTRIM(REQDTF.FKOWHCD) LIKE RTRIM(:B3 ) ) AND ( REQDTF.FREQDTFLG <> :B2 ) AND ( REQDTF.FKOITEMNO = ITEMM_B.FITEMNO) AND ( RTRIM(ITEMM_B.FITEMTYP) LIKE :B1 ) AND ( NVL(MORLSF.FMOISSFLG,'N') <> 'C')
