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

13c AGENT DEPLOYMENT PROCESS CRASHES 


ON REDHAT/OEL 7.X TARGET HOSTS

SOLUTION

Add the following lines on a target machine either into .bash_profile or .bashrc file and retry the agent deployment

export TMP=/tmp
export _JAVA_OPTIONS="-Xms256m -Xmx512m"
export EM_COMMON_JAVA_OPTIONS="-Xms256m -Xmx512m"

NOTE: After an agent is deployed successfully the lines can be removed.

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.

Оставим в каждой группе только по одной строке с порядковым номером 1,
для этого найдём строки в каждой группе с порядковым номером большим чем 1.
Эти строки необходимо удалить.


SELECT * FROM
  (SELECT  rowid, ROW_NUMBER() OVER (PARTITION BY ENAME, JOB, HIREDATE ORDER BY rowid) RN
   FROM EMP)
WHERE RN > 1;

Вывод только rowid этих строк.

SELECT rowid FROM
  (SELECT  rowid, ROW_NUMBER() OVER (PARTITION BY ENAME, JOB, HIREDATE ORDER BY rowid) RN
   FROM EMP)
WHERE RN > 1;


ROWID

AAAPQIAAEAAAAC7AAP
AAAPQIAAEAAAAC7AAQ


Удаляем лишние строки по их rowid

DELETE FROM EMP WHERE rowid IN (
SELECT rowid FROM
  (SELECT  rowid, ROW_NUMBER() OVER (PARTITION BY ENAME, JOB, HIREDATE ORDER BY rowid) RN
   FROM EMP)
WHERE RN > 1);
