Hello List,

I have two questions about SMU. Any suggestion is appreciated.

1) who used undo segments by how much? I am not asking who IS USING here, w=
hich is easy to know by querying v$tranaction, v$process, and etc.
2) when will the undo segment space be released? The parameter undo_retenti=
on does not tell unless I know who used how much undo at what time?

Thanks,

Michael=20
