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.

How Buffer Cache Works

May 28, 2016 3:55PM edited May 28, 2016 3:56PM in Using the My Oracle Support Portal (MOSC) Question

Hi Everyone,

Hope you are all doing good.

I Have a query regarding the buffer cache mechanism.

If my SGA size is 10Gb and My table size is 20Gb. I have fired a query select * from <my_table_name>;

can anyone please explain me clearly how internal process will happen when table size is greater than SGA memory size ?

Thanks in advance.

Regards,

Satya Kadarla.
