Query giving performance issues.

Question

Hi All,
Following query is giving performance issues. Query execution is taking around 11 minutes. Our client requirement is to get the data for the query in 30 sec to 1 min. Please suggest.
SELECT
DISTINCT r.rptid, p.product_id, p.vnd_dscr, p.vendor_cd, p.Firm_Cd, a.is_mm_sweep IsMoneyMarket
FROM
dev.ac_cube a,
dev.rpt_master_rep_list_view r,
dev.cur_ps_cube p
WHERE a.repid = r.rep_id
AND a.accountkey = p.accountkey
AND p.product_id IS NOT NULL
AND p.product_id != 'CASH'
AND r.RPTID = '42817'
Number of distinct records fetched by above query : 34445
Number of records in dev.ac_cube table : 13.6 million
Number of records in dev.cur_ps_cube table : 7 million
Number of records in dev.rpt_master_rep_list_view for RPTID '42817' : 118354
repid, product_id is indexed column in dev.ac_cube table. accountkey is primary key in dev.ac_cube table.
rep_id is indexed column in base table on which dev.rpt_master_rep_list_view view is created

The output is not complete as i expected. Have you followed the steps I have mentioned in my earlier post
Also when posting output enclose between two {*code*} ...{*code*} (remove * within braces). It displays everything between the tags as proper formatted output otherwise its really hard to read and understand
See sample below. However you need to get the session id, sql id, display_cursor output exactly in same way as mentioned in my previous post
SQL> set arraysize 200 timing on serveroutput on linesize 200;
SQL> set autotrace traceonly explain statistics;
SQL> select level from dual  connect by level <= 10000;
10000 rows selected.
