One of the new features of rman in Oracle Database 12c is the topic of this short document. For many years since we first saw rman around 1994 (?) it was touted as the “weakest solution” for object-based recovery. We went through the lengthy and labour-intensive process of creating an additional instance destined to be the target of a restore for the tablespace(s) containing the missing table followed by an export/import back into the table’s original location.
From my experience with this feature so far, I have discovered the following requirements for being able to pull off table-level recovery:
- An rman backup containing the missing table must exist; it cannot rely on a backup from before the table was created alongside the application of archived redo.
- The table cannot belong to SYS or SYSTEM and cannot reside in SYSTEM or SYSAUX.
There could indeed be more as per the Oracle documentation that should be consulted before going any further. The script to pull this off is surprisingly simple …
recover SCHEMA.OBJECT NAME until SCN|TIME auxiliary destination 'LOCATION FOR TEMP INSTANCE';
What could be simpler? As of yet I have not experienced any issues with this feature.

Hi ,
Thanks for posting this this was quite helpful. It looks like in near future database administrators will be obsolete as everything is being automated.
I got the same error at the end.. But there wese no rows in newly created table.
Please reply
