Как узнать Absolute Fuzzy SCN:
БД можно открыть когда у всех датафайлов не только одинаковый CHECKPOINT_CHANGE#, но и когда FUZZY бит равен нулю.
Нужно вычислить на каком scn fuzzy bit сбрасывается.
RMAN> RESTORE DATABASE PREVIEW ;
Recovery must be done beyond SCN 47530561 to clear datafile fuzziness
или так:
spool scandatafile.sql
set serveroutput on
declare
scn number(12) := 0;
scnmax number(12) := 0;
begin
for f in (select * from v$datafile) loop
scn := dbms_backup_restore.scandatafile(f.file#);
dbms_output.put_line('File ' || f.file# ||' absolute fuzzy scn = ' || scn);
if scn > scnmax then scnmax := scn; end if;
end loop;
dbms_output.put_line('Minimum PITR SCN = ' || scnmax);
end;
или с помощью трассировки:
SQL>alter session set events 'immediate trace name file_hdrs level 3';
смотрим трассировочный файл, там пишет
...
DATA FILE #4:
name #4: D:\ORA11G\ORCL\USERS01.DBF
...
Absolute fuzzy scn: 0x0000.02d54241
...
Т.е. гнать нужно как минимум до scn = 47530561
RMAN> recover database until scn 47530560;
Тут база не откроется.
RMAN> recover database until scn 47530561;
media recovery complete, elapsed time: 00:00:01
RMAN> alter database open resetlogs;
Мониторинг RMAN BACKUPS:
In RC_BACKUP_SET_DETAILS the Backup_type has the following values set :-
BACKUP_TYPE: The type of the backup:
D (full backup or level 0 incremental),
I (incremental level 1),
L (archived redo log).
This works as expected in 11gr2 and Below version.
However in 12c database When we take a Level 0 backup the backup type is Shown as I and not D.
BUG 25055352 - RC_BACKUP_SET_DETAILS.BACKUP_TYPE INCORRECTLY SHOWS LEVEL 0 AS I ---> Closed as Duplicate of BUG 23248000 - RC_BACKUP_SET_DETAILS.BACKUP_TYPE INCORRECTLY SHOWS

Получить расписание для календарной строки:
Процедура принимает четыре параметра:calendar_string Обрабатываемая календарная строка.
start_date Дата (в виде значения типа TIMESTAMP), с которой следует начать.
return_date_after Если необходимо указывать даты и моменты времени, стоящие после какой-то определенной даты, то используйте этот параметр для начала последовательности планируемых после данной даты дат.
next_run_date Это выходной параметр. Процедура записывает в него дату и время, когда планировщик будет выполнять данную календарную строку.
