Answer / vinodh ramaswamy
when the transaction is started rollback segment uses the extents in cyclic fashion and once the extents gets fill these extents are marked as inactive.
if one extent is not sufficient then it searches for new adjacent free extents it wont use the previous free extents it always move in cyclic manner if next extent is not free it create a new free extent dynamically.
if all extents in the rollback segment are gets filled then it orverwrites the inactive extents.

Answer / orawhiz
It will try to fit the transaction in a cyclic fashion
to all existing extents. Once it found an extent is in use
then it forced to acquire a new extent (No. of extents is
based on the optimal size)
