You can now restore single tables from backup! It is a simple command although it leads to much effort by RMAN. See it as an enhancement over a ’normal‘ Point In Time Recovery:
Point In Time Recovery
After a full restore from a sufficiently old backup, archived logs are being applied in direction of the presence until before the logical error. Then a new incarnation comes up (with RESETLOGS) and the whole database is as it was at that time. But what if it is only a dropped table that needs to be recovered? Enter the 12c New Feature:
Table Recovery
Above is what RMAN does upon Table Recovery. The restore is done to the auxiliary destination, while the database keeps on running like it is just now. The new incarnation is there only temporarily, just to export the dropped table from. Afterwards, it is removed. RMAN will then import the table back to the still running database – unless you say otherwise with the NOTABLEIMPORT clause. So it is a huge effort to go through for the system in spite of the simple RMAN command:
SQL> select count(*) from sales; COUNT(*) ---------- 10000000 SQL> select sysdate from dual; SYSDATE ------------------- 2015-07-02 09:33:37 SQL> drop table sales purge; Table dropped.
Oops – that was a mistake! And I can’t simply say flashback table sales to before drop because of the purge. RMAN to the rescue!
