How to treat data in a long query

Question

I have a query (over a table connected by dblink) that returns me a lot of rows (over 7 millions), when I try to got data at each row i got an out of memory problem. So I want to view records in legs, but i don't know how to do that in my procedure.
The query is asigned to a cursor and I pass the data I need of each row to another table.
This is the code I have:
CURSOR r_cursor
IS
SELECT *
FROM med_principio_activo@midblink
cursor1 r_cursor%ROWTYPE;
begin
LOOP
FETCH r_cursor
INTO cursor1;
EXIT WHEN r_cursor%NOTFOUND;
SELECT MAX(SID)
INTO medic
FROM medicam
WHERE cursor1.codmedic LIKE xkey;
SELECT MAX(SID)
INTO ppioact
FROM activeingredient
WHERE cursor1.codppioact LIKE xkey;
INSERT INTO med_medicamentai
(medicament, activeingredient
VALUES (medic, ppioact
COMMIT;
END LOOP;
I want to do legs of 10000 records to read all info and got memory free, but i don't know how to do that...
Thnaks,

Hi,
instead of using PL/SQL using cursor you could have insert directly in the table,
like
INSERT INTO med_medicamentai
(medicament, activeingredient
VALUES (
Before that we need to know how the data in med_principio_activo@midblink
,medicam and activeingredient are related.
If you want to use cursor, then bulk collect will improve the performance.
Please look at this link for more info.
