Any similarity to actual environments, actual persons, living or dead, is purely coincidental and not intended in any manner.

For the purposes of this document, the following fictitious environment is used as an example to describe the procedure:  为了本文档的目的，以下虚拟环境用作描述此过程的示例

Target Database:
DB_NAME: T12CCDB
PDB_NAME: T12CPDB1
SCHEMA:  SMEDS
TABLE: RECTEST 
NEW_TABLE:  TEST_RECTEST
AUXILIARY_LOCATION:  /testcases/rectbl/

***********  

The RECOVER TABLE command is a new feature in 12C that allows point in time recovery of a table or a table partition.  RECOVER TABLE命令是12C中的一项新功能，它允许对表或表分区进行时间点恢复
The table is recovered into an auxiliary instance and there is the option to:  该表将恢复到辅助实例中，并且可以选择

• import the recovered table into a new table or partition using REMAP option  使用REMAP选项将恢复的表导入到新表或分区中
• create the expdp dump of the recovered table only, for import at a later time of your choosing  仅创建已恢复表的expdp dump，以供以后选择时导入

Pre-requisites:  先决条件

• The target database must be in read-write mode.  目标数据库必须处于读写模式
• The target database must be in ARCHIVELOG mode.  目标数据库必须处于ARCHIVELOG模式
• You must have RMAN backups of the tables or table partitions as they existed at the point in time to which you want recover  these objects.  您必须具有要恢复这些对象的时间点上存在的表或表分区的RMAN备份
• To recover single table partitions, the COMPATIBLE initialization parameter for target database must be set to 11.1.0 or higher.  要恢复单个表分区，目标数据库的COMPATIBLE初始化参数必须设置为11.1.0或更高
• Please ensure the auxiliary destination has enough space for  restore of system, sysaux ,undo  and the required tablespace for the table recovery.  请确保辅助目标有足够的空间来还原系统，sysaux，undo和恢复表所需的表空间
  Please note these files in auxiliary destination would removed automatically once the table is recovery  请注意，一旦恢复表，辅助目标中的这些文件将自动删除

Setting the Point-in-time to Which Tables and Table Partitions Must be Recovered  设置必须恢复表和表分区的时间点
Options are:  选项有

• SCN
• Time
• Sequence number

The ROOT container SYSTEM and UNDO tablespaces are restored to the auxiliary therefore RECOVER TABLE has to be run after a direct connection to ROOT CDB.  If a service_name is not used, RMAN will fail during export:
ROOT 容器 SYSTEM 和 UNDO 表空间已还原到辅助表，因此在直接连接到ROOT CDB之后必须运行RECOVER TABLE。如果未使用service_name，则RMAN在导出期间将失败

Point in Time TABLE RECOVERY Example  时间点表恢复示例

Table RECTEST in schema SMEDS to be recovered into new table SMEDS.TEST_RECTEST.  schema SMEDS中的表R??ECTEST要恢复到新表SMEDS.TEST_RECTEST中。
The auxiliary instance datafiles will be restored to ‘/testcases/rectbl/‘.   辅助实例数据文件将还原到 ‘/testcases/rectbl/‘。

% rman target sys/<password>@t12ccdb log /tmp/recover_table.log
