在12C以前的版本中rman可以进行db,tablespace,datafile,block级别和TSPITR的恢复,12C引入了table级别的恢复
在没有打开flashback的时候可以进行单个表的恢复.
 
例,创建表

SQL>  alter session set container=pdb2;

Session altered.

SQL> create table frank.t1 as select * from dba_tables;

Table created.

备份数据库

RMAN> backup database;

Starting backup at 16-JAN-14
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=265 device type=DISK
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
input datafile file number=00003 name=/u01/app/oracle/oradata/c12/sysaux01.dbf
input datafile file number=00001 name=/u01/app/oracle/oradata/c12/system01.dbf
input datafile file number=00004 name=/u01/app/oracle/oradata/c12/undotbs01.dbf
input datafile file number=00038 name=/home/oracle/t1.dbf
input datafile file number=00006 name=/u01/app/oracle/oradata/c12/users01.dbf
input datafile file number=00014 name=/u01/app/oracle/product/12.1.0/db_1/dbs/test

查询当前数据库的scn号

SQL> select current_scn from v$database;

CURRENT_SCN
-----------
    4898443

SQL> drop table frank.t1;

[oracle@o12c ~]$ mkdir /home/oracle/abc

RMAN> recover table frank.t1 of pluggable database pdb2
2>  until scn 4898443
3>  auxiliary destination '/home/oracle/abc'
4>   datapump destination '/home/oracle/abc';

Starting recover at 16-JAN-14

也是会新建一个auxiliary  instance,然后在auxiliary instance上做全库恢复再通过datapump工具导出和导入
整个过程和TSPITR极为相似.

恢复成功再次查询

SQL> select count(*) from frank.t1;

  COUNT(*)
----------
        2318

注意common user引用表的名称为 "c##frank".t1,而不是"c##frank.t1",否则会报以下错误
RMAN> recover table "c##frank.t1" until scn 4894140 auxiliary destination '/home/oracle/abc' datapump destination '/home/oracle/abc';
