Performance of the server [message #51778]

I have written a simple procedure like this :--->

create or replace
procedure update_publisher
is
cursor p is select pub_code from publishers;
i number(8);
begin
i := 0;
for prec in p
loop
i := i + 1;
update publishers set pub_code = i
where pub_code = prec.pub_code;
update main_book_details set pub_code = i
where pub_code = prec.pub_code;
commit;
end loop;
end;

There are 33000 records in publishers table and around 100000(one lakh) records in main_book_details table. But this procedure is taking more and more time (nearly eight hours) for updation of this much of records.Even insert statement is executng very slow for large no of records.Is there any parameter setting problem?How to remove this problem ?Please send the solution.

   Seems you are issuing COMMIT for every single record
   for each loop. consider changing that
   try to issue a commit for every 1000 records or
   2000 records. u can use a mod function to do that.
