SQL Query taking the different time in Production and Development Env.

Question

Hi All,
Following is the query which is hitting mainly two tables. SA_ORDER & AC_INVOICE.
My Production and Development both has same amount of data. But in Development env. it is just taking 5 secs. to execute but in Production Env. its handing.
I have also execution plans of both env. The difference is in development env. it is showing some view i.e. SYS.VW_NSO_1 which is not getting used in Production env.
And one more input is in Production Env, I don't have DBA privileges.
What setting will I have to make to resolve this performance problem in Production Env. ?
Here is the QUERY:------------
SELECT distinct A.GL_COMPANY_ID,
A.CUSTOMER_GROUP_ID,
A.CUSTOMER_GROUP_NAME,
A.INVOICE_ID,
A.ORDER_ID,
B.ORDER_NAME,
A.CUSTOMER_ID,
A.CUSTOMER_NAME,
c.order_name parent_order_name,
A.INVOICE_DATE,
A.DUE_DATE,
A.TOTAL_INVOICED_AMOUNT,
A.TOTAL_PAID_AMOUNT,
A.CREDITED_AMOUNT,
H.write_off
from ac_invoice a,
sa_order b,
(select parent_invoice_id, sum(total_invoiced_amount) write_off
from ac_invoice
where invoice_type_id = 3
group by parent_invoice_id) H,
(select order_id, order_name from sa_order where order_type_id in (3)) c
WHERE a.order_id = b.order_id and a.invoice_id = H.parent_invoice_id(+) and
b.parent_order_id = c.order_id(+) and
a.invoice_id NOT IN
((SELECT invoice_id
FROM ac_invoice
WHERE parent_invoice_id IS NOT NULL AND invoice_type_id != 3)
UNION
(SELECT parent_invoice_id
FROM ac_invoice
WHERE parent_invoice_id IS NOT NULL AND invoice_type_id != 3)) and
A.GL_COMPANY_ID = 1 and UPPER(A.customer_name) like upper('%KTLA%')
and
invoice_type_id in (1, 3, 4, 5, 2) and a.invoice_status_id = 1
ORDER BY A.INVOICE_ID
