This cannot happen so don't worry about it.

For the rest of the information, again, the docs are your friend.

Active Transactions

Rollback of Transactions

Just to clarify the concept;
I run the update that impacted 1000's of rows and changed data.
Before change data image is recorded in the undo tbs.
Any data change is also recorded in the logfile.

I do not commit and run the rollback

how oracle will react to this?
if undo tbs was not able to record all the before change image.
what happen to the data that is recorded in the logfile?
