Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

DWH 11gR2 / Forcing DYNAMIC SAMPLING / EXECUTE IMMEDIATE

Feb 20, 2013 1:31PM edited May 23, 2013 5:31AM in SQL Performance (MOSC) 7 commentsAnswered

Hello,I have a 11gR2 DWH database.

How to ignore statistics 11gR2 and force the use of DYNAMIC SAMPLING 10 in all queries even when objects have statistics ?

Is this(DYNAMIC SAMPLING) a good idea in a DWH using only queries with EXECUTE IMMEIDATE?

Best regards .

GD.
