we have a SCM 5.00 with kernel 7.00 on oracle 10.2.0.4 .
In Db02 , also after a refresh , we have the tablespace at 99% busy.
If a check it in brtools it shows 0,5% busy.
I think that brtools shows the correct answer but i don't know why there is this difference.
SQL> show parameter undo
NAME TYPE VALUE
inmemory_undo boolean FALSE
undo_management string AUTO
undo_retention integer 36000
undo_tablespace string PSAPUNDO
I refeshed statistics in db02old and in db02 but the difference remains.
