Merge slow & running out of rollback and tem space

Question

I try to merge temp table to target table everyday.Txt files are loaded in temp table every day( 800000 rows) this need to merge to target table every day
it takes 4 to 5 hrs , temp table dont have index, target tabe have index-- idx_hpp
and it have stats below is the syntax which i am using pls help how i can solve this
problem-- slow, runnnig out of temp space,rollback
merge /*+ index( IDX_hpp) */ /*+ PARALLEL ( hpp,10) APPEND) */ into hpp s
using
(SELECT * FROM hpp_temp) t
on
(s.b_code=t.B_CODE
and s.i_no = t.i_no
and nvl(s.V_TYPE,'X')=nvl(t.V_TYPE,'X')
and nvl(s.s_invoice,'X') = nvl(t.s_invoice,'X'))
--and  nvl(s.I_RECEIVER,'X') = nvl(t.I_RECEIVER,'X'))
--and substr(t.i_no,1,3) not between 'C' and 'Z')
when matched then
update /*+ INDEX (IDX_HPP) */
set s.REF_V_NO = t.REF_V_NO
,s.I_CNOTE=t.I_CNOTE,
s.O_STORNO=t.O_STORNO
where b_code=t.B_CODE and i_no = t.i_no and NVL(V_TYPE,'X')=NVL(t.V_TYPE,'X')
and NVL(s.REF_V_NO,'X') != NVL(t.REF_V_NO,'X') and
nvl(I_RECEIVER,'X') = nvl(t.I_RECEIVER,'X')
and substr(t.i_no,1,3) not between 'C' and 'Z'
