Performance issue in executing a procedure

Question

Hi all,
I am trying to insert some data into an empty column of a table that already contains 2Lakh data using a procedure in oracle.The procedure is executing without error but it is taking more time(i cancelled the execution and checked the table.it inserted only 50000 data in half-an-hour of time).
Here is the procedure :
create or replace procedure PROC_INSERT
as
i number;
b number;
rc number;
cursor c1 is select count(1) from copy_tm;
begin
open c1;
fetch c1 into rc;
b:=50;
i:=1;
if c1%found then
for i in 1..rc LOOP
update copy_tm set mainoffer =b where series =i;
commit;
b:=b+1;
if b =100 then
b:=50;
end if;
end loop;
end if;
close c1;
end;
Can u tell me whats wrong with the procedure?
Thanks,
Dpa

First, its not the right forum to ask this question.
Secondly, what is the version of database you are using. Have you tried parallel DML?
