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.

One SQL ID with multiple execution plans

Hi

We have a basic question on this subject

If we see a SQL ID with more than one execution plan, what could be the main / primary reason(s) for that?

Which execution plan will oracle pick to use when that happens?

The Database is 11.2.0.4

Thanks
