Pre-12c restoring a table was a long and difficult task. But Oracle 12c introduced new feature to restore a single table or a single partition of a partitioned table from an RMAN backup via the RECOVER TABLE command.
Here is what RMAN RECOVER TABLE command does:
It creates an auxiliary instance to recover the tables to a specific point in time. This contains a few system related data files like SYSTEM, SYSAUX, UNDO and data files belonging to the tablespace containing the tables we are looking to restore.
In this example it restores SYSTEM,SYSAUX,UNDO tablespaces for CDB and SYSTEM and SYSAUX and tablespace for PDB
Then it creates a Data Pump export dump file which contains the recovered table or partitions of tables.
It then imports the data into the target database using Data Pump Import.
Finally it removes the temporary auxiliary instance.
Test case:
RMAN> recover table "TEST".testtab of pluggable database ggat_b until time "to_date('07-07-2013 00:50:00', 'dd-mm-yyyy hh24:mi:ss')" auxiliary destination '/usr/orasys/tmp' datapump destination '/usr/orasys/tmp' dump file 'test_dump';
