    Question meaning of status column of dba_undo_extents

    Hi,
    I want to know the meaning of status column of dba_undo_extents . I have seen 3 possible values - ACTIVE, EXPIRED, UNEXPIRED. What are the meanings ? I am trying to guess - ACTIVE means that this undo segment contains active transactions - EXPIRED means that this segment is not rqeuired at all ( considering Undo retention period )- UNEXPIRED means that this segment does not contain any active transactions but it contains transactions which are still required for Flashback option ( considering Undo retention period ).

    The version of the database is 9i rel 2.

    Am I right ?

    Thanks

    Deba
