Hi,
I have set my undo_tbs to 1.2gb. It should be release back the space after the process (that taken 700M) commited, rite?
But I notice that there are nothing change to reduce the freespace of the undo_tbs. Would it mean that the undo_tbs will keep on increasing? or How to release the space for my undo_tbs ?
Please advise
Thanks

it wont get released because it has to use it for flashback queries, it will free when he has to
if you dont want to use flashback then set undo_retention to 0...

undo
set the undo_retention to low value and even after the active extent becomes inactive immediately space will not be realeased.
