Jonl, I think reading the material as referenced by JG is a good idea.
How long Oracle holds change data in the undo tablespace is a factor of
the undo retention period and how much committed change data is
generated. Once Oracle has used all available undo the rdbms will
start discarding committed data even if it is less than the retention
period unless guarentee has been set. But it you had enough rbs space
now you should have enough space under the new setup. Uncommitted data
will be held even past the retention period as long as space exists or
can be made.
