| | Hy NG,
| |
| |
| | is there
| | 1) a view or a table where i can select the actuel scn-number from the db ?
| | 2) if the db is down (offline), can i see the last scn-number ? in
| | ctrl-file, data-file, logfile (in alert-file, i
| | know)
| |
| |
| | Thanks .....
| |
|
| 1. select dbms_flashback.get_system_change_number from dual;
| 2. It is in the control file but you can't see it.
| Maybe in the mount state there is a x$ table containing that?

Assuming the last shutdown was not abort, in the mount state, you can get it with:

select checkpoint_change# from v$database;     -- from control file
select checkpoint_change#, last_changes# from v$datafile;  -- from control file
select checkpoint_change# from v$datafile_header;    -- from datafile headers
