Need to commit after every 10 000 records inserted ?

Question

What would be the best way to Commit after every 10 000 records inserted from one table to the other using the following script :
DECLARE
l_max_repa_id x_received_p.repa_id%TYPE;
l_max_rept_id x_received_p_trans.rept_id%TYPE;
BEGIN
SELECT MAX (repa_id)
INTO l_max_repa_id
FROM x_received_p
WHERE repa_modifieddate <= ADD_MONTHS (SYSDATE, -6);
SELECT MAX (rept_id)
INTO l_max_rept_id
FROM x_received_p_trans
WHERE rept_repa_id = l_max_repa_id;
INSERT INTO x_p_requests_arch
SELECT *
FROM x_p_requests
WHERE pare_repa_id <= l_max_rept_id;
DELETE FROM x__requests
WHERE pare_repa_id <= l_max_rept_id;

we are moving between 5 and 10 million records from the one table to the other table and it takes forever.
Please could you provide me with a script just to commit after every x amount of records ? :)I concur with the other responses.
Committing every N records will slow down the process, not speed it up.
The fastest way to move your data (and 10 million rows is nothing, we do those sorts of volumes frequently ourselves) is to use a single SQL statement to do an INSERT ... SELECT ... statement (or a CREATE TABLE ... AS SELECT ... statement as appropriate).
If those SQL statements are running slowly then you need to look at what's causing the performance issue of the SELECT statement, and tackle that issue, which may be a case of simply getting the database statistics up to date, or applying a new index to a table etc. or re-writing the select statement to tackle the query in a different way.
So, deal with the cause of the performance issue, don't try and fudge your way around it, which will only create further problems.
