Oracle 12c: Table-Point-in-Time-Recovery in einer Multitenant Umgebung
Mit Oracle 12c hat Oracle die Funktion “Table-Point-in-Time-Recovery”, kurz TPITR, eingeführt. Diese Funktion vereinigt die bisherige Vorgehensweise “Tablespace-Point-in-Time-Recovery – Export – Import” in einem Befehl und erlaubt es, eine Tabelle über “Flashback Table” hinaus auf einen alten Stand zu setzen. Auch ein Recovery einzelner Partitionen ist möglich.
TPITR funktioniert auch sehr schön in Kombination mit der Multitenant-Option von Oracle 12c.

Die Fehlermeldungen “ORA-31684” wegen der doppelten Constraint-Namen sind zwar ärgerlich,
aber meiner Meinung nach in dem Gesamtkontext zu verschmerzen. Hauptsache, der alte
Stand der Daten ist wieder da:
Und das Ergebnis in der Datenbank ist:
SQL> select empno,ename,sal from scott.emp where ename='KING';
EMPNO ENAME SAL
---------- ---------- ----------
7839 KING 5500
SQL> select empno,ename,sal from scott.emp_OLD where ename=’KING’;
EMPNO ENAME SAL
———- ———- ———-
7839 KING 5000
.. jetzt können wir also auch über passende Updates die versehentliche Gehaltserhöhung
(= der angenommene Grund für den TPITR) rückgängig machen.
Die Dump-Datei verbleibt auch auf dem Server:oracle@training:~/ [TVD12CDB] ls -l /u01/aux/AUX/*.dmp

TPITR funktioniert auch im Root-Container (CDB$ROOT) – obwohl dort natürlich keine Applikationsobjekte abgelegt sein sollten.
Aber Achtung: wenn man mit dem Default-Prefix für die Common User (= “C##”), dann ergibt der naheliegende Befehl
RMAN> recover table C##CDB_DBA_ADMIN1.dept until scn 4993005 auxiliary destination '/u01/aux/AUX' remap table C##CDB_DBA_ADMIN1.dept:dept_old;
eine Fehlermeldung:

Der Workaround ist, den Usernamen in doppelte Anführungszeichen einzuschließen:
RMAN> recover table "C##CDB_DBA_ADMIN1".dept until scn 4993005 auxiliary destination '/u01/aux/AUX' remap table "C##CDB_DBA_ADMIN1".dept:dept_old;

Insgesamt ist TPITR ein hilfreiches Feature, das zwar nichts grundlegend Neues bietet, aber bekannte Abläufe sinnvoll zusammenfasst.
Weitere Informationen zur “Table-Point-in-Time-Recovery” gibt es im Backup & Recovery Users Guide.
Nachtrag (18.12.2014):
Auch wenn nur ein kleiner Teil eines Datafiles für das Recovery einer Tabelle benötigt wird, wird trotzdem das komplette Datafile restored.
