Hi,
I have some doubts related to Undo Segment please help me.
I have created a table called Toy and If a user named Raj has increased the toy price from 30$ to 50$ but not commited then the old image wil be stored in undo segment.
Question:-
1) Whether all the users except Raj will be accessing toy price from undo segment directly or that undo segment data is brought to Bufer Cache from Server Process so that all users can access that data from Buffer Cache?
2) Is there any way to know whether data is being accessed from Undo Segment or Buffer Cache?
Regards,
Naveen |
