From the rman repository, which may be in the controlfile, or the rman
catalog database.
controlfile:
select file_type, stamp, RL_SEQUENCE# , RL_FIRST_CHANGE#, RL_NEXT_CHANGE#,
RL_NEXT_TIME
from v$backup_files
/
To find all tables/views that have both sequence# and change#, use the
following query:
If you do so on an rman
select sequence#,first_change#,next_change#
from v$log_history;
with systab as (
select
owner,
table_name
from dba_tab_columns
where owner like 'SYS'
and column_name like '%SEQUENCE#'
intersect
select
owner,
table_name
from dba_tab_columns
where owner like 'SYS'
and column_name like '%CHANGE#'
)
select s.owner, s.table_name, tc.column_name
from systab s
join dba_tab_columns tc on tc.owner = s.owner and tc.table_name =
s.table_name
where tc.column_name like '%CHANGE#'
or tc.column_name like '%SEQUENCE#'
order by owner, table_name, column_name
You can do a similar search in the catalog if you use one.
