Question : Exception handling for insert statement

Need a simple program that inserts records into a table and delete some records after the insert is successful. I have to check for exceptions and commit at the right place. I not sure what exceptions I should check for the insert and when to do the commit.

Here is the same proc I wrote. Please suggest a better way of handling exception and deletes after the insert is successful.

create or replace procedure insert_adj_rec (P_btch_id batch.btchid%type)
IS
l_trans_id      trans.trans_id%type := 123;

BEGIN
INSERT INTO TABLE1 (
COL1,
COL2,
COL3)
VALUES (
SELECT COL1,
COL2,
amount * -1 ------make negative to postive
FROM TABLE2
WHERE BTCH_ID = P_BATCH_ID
AND trans_id = l_Trans_id
and amount < 0);

---after insert is success delete negative amounts
delete from table2
where amount < 0;

COMMIT;                
EXCEPTION
      WHEN DUP_VAL_ON_INDEX THEN ---not sure if this is right
      DBMS_OUTPUT.PUT_LINE ('DUPLICATE RECORD - ' || SQLERRM);
      ROLLBACK;
END;

Max points because of urgency.

Bit tricky. Are the servers members of a domain?

I'm thinking that if you get php to run under a user account, you can add that user's perms to the network share permissions:-
