You Asked

Hi Tom,
we came across the request from customers.

There were some activities on table (let's name it T1),
audit was not turned on from the creation of db.

Customer raised request to provide some trace or audit for T1-
all activities for past 3 days - 10,11,12 October 2016.

Is there any table or file - where we can check and get it?

With regards!

If you've not enabled auditing and haven't built any of your own logging then this information is gone!

If you're lucky and your system has a large undo_retention set you may be able to see the recent changes using a flashback "versions between" query:

select t.*,
       versions_xid,
       versions_operation,
       versions_startscn,
       versions_endscn
from   t versions between timestamp sysdate - 1/1440 and sysdate


But in all likelihood this information is gone!
