Oracle 12C使用RMAN将Non-CDB中多个用户方案中的多个表或表分区恢复到新用户方案中

Oracle 12C使用RMAN将Non-CDB中多个用户方案中的多个表或表分区恢复到新用户方案中的操作如下
1.对整个Non-CDB(orcl)生成RMAN备份 

RMAN> backup as compressed backupset database format '+data/backup/%d_%I_%U_%t' plus archivelog format 'arc_%d_%T_%U';

2.在删除表t_emp之前记录当前时间,在执行恢复时它们被用来指定恢复时间点 

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

  COUNT(*)
----------
         8

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

  COUNT(*)
----------
         8

1 row selected.

SQL> select sysdate from dual;

SYSDATE
-------------------
2018-01-10 22:56:16

1 row selected.

SQL> truncate table cs.t1;

Table truncated.

SQL> truncate table hr.t1;

Table truncated.

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

  COUNT(*)
----------
         0

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

  COUNT(*)
----------
         0

3.启动RMAN并使用有sysbacup或sysdba权限的用户连接到目标数据库 

[oracle@jytest3 ~]$ export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
[oracle@jytest3 ~]$ rman target/

Recovery Manager: Release 12.2.0.1.0 - Production on Wed Jan 10 02:22:13 2018

Copyright (c) 1982, 2017, Oracle and/or its affiliates.  All rights reserved.

connected to target database: ORCL (DBID=1492772871)

4.通过使用recover table命令将要被恢复的表或表分区恢复到指定的时间点。 使用auxiliary destination子句（/ora_xtts/recover辅助数据文件存储目录)与until scn来指定恢复时间点,并且在recover命令中使用子句 dump file与datapump destination，指定包含被恢复表或表分区的导出dump文件的文件名(t_emp_recvr.dmp)与存储位置(/ora_xtts/dump)。 使用remap table子句将hr.t1恢复成jy.t1_1,cs.t1恢复成jy.t1_2。使用remap tablespace子句将hr与cs用户方案中的表t1从恢复到jy用户方案中 

RMAN> run
2> {
3> recover table hr.t1,cs.t1
4> until time '2018-01-10 22:55:39'
5> auxiliary destination '/ora_xtts/recover'
6> datapump destination '/ora_xtts/dump'
7> dump file 't_emp_recvr.dmp'
8> remap table 'HR'.'T1':'JY'.'T1_1','CS'.'T1':'JY'.'T1_2'
9> remap tablespace 'USERS':'USERTBS';
10> }
