baskarb_2006,

Please provide the query also in the forum. It may help others to look at and give you suggestion.

second, did you check the query whether it has proper join or not?

Did you or DBA ran gather statistics?

Look out there are so many places it does full table scan which has more rows.

300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
458131 TABLE ACCESS FULL SUM_OPEN_POS 1 10 ANALYZED 165
5320325 TABLE ACCESS FULL DM_GLOBAL_PRICING_EXP 1 1 ANALYZED 161
170493 TABLE ACCESS FULL DM_GLOBAL_PRICING_EXP 1 1 ANALYZED 161
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
458131 TABLE ACCESS FULL SUM_OPEN_POS 1 10 ANALYZED 165
5349050 TABLE ACCESS FULL DM_GLOBAL_PRICING_EXP 1 1 ANALYZED 161
171414 TABLE ACCESS FULL DM_GLOBAL_PRICING_EXP 1 1 ANALYZED 161
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
12472 TABLE ACCESS FULL DM_CUST_GLOBAL_PRICING_EXP 1 1 ANALYZED 39
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
12472 TABLE ACCESS FULL DM_CUST_GLOBAL_PRICING_EXP 1 1 ANALYZED 39
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
12595 TABLE ACCESS FULL DM_CUST_GLOBAL_PRICING_EXP 1 1 ANALYZED 39
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97
12595 TABLE ACCESS FULL DM_CUST_GLOBAL_PRICING_EXP 1 1 ANALYZED 39
300438 TABLE ACCESS FULL SUM_SUPER_AML 1 10 ANALYZED 97

You need to look at the query, joins and if need be create indexes.
