CN is not stored at all. A list of CommitNumbers is generated looking
into TIP on database init in memory. Then it's mainainted in

The term SCN is already used by nbackup, lets not muddle the waters by overloading it for
another usecase.
Taking into account usage of "SCN" term in Oracle, it is better to invent a new one for
nbackup than for transaction-related counter.
