Hello,
You need to check the indexes on the tables as well.

Hi,
This is a three-node RAC environment running an Oracle EBS database. The
database version is 11.2.0.4 and the OS is Solaris 11. The While
investigating the execution plan of a SQL statement (a standard EBS
statement), I ran the following statement for a particular SQL_ID:
SELECT
inst_id,
sql_id,
child_number,
id,
name,
isdefault,
value
FROM
gv$sql_optimizer_env
WHERE
sql_id = '&m_sql_id' AND
isdefault = 'NO'
ORDER BY
inst_id,
name
;
INST_ID SQL_ID CHILD_NUMBER ID
NAME ISD VALUE

15 rows selected.
I have checked all the tables involved in the query and none of them have
any DOP set. I am curious to know how Oracle is setting this parameter?
Thanks,
Amir
