测试库（oracle 12c）下有一个pdb数据库pdbeisoo，其中有表空间TBS_PDBEISOO，对应的数据文件E:\APP\ORCL\ORADATA\ORCL\EISOO\PDBEISOO.DBF损坏，从之前的RMAN备份（备份命令如下）中该数据文件。

RMAN> backup pluggable database pdbeisoo include current controlfile plus archivelog;


数据状态如下：
SQL> select con_id,name,open_mode from v$pdbs;

    CON_ID NAME                                               OPEN_MODE
---------- ------------------------------------------------------------------------------------------ ------------------------------
     2 PDB$SEED                                              READ ONLY
     3 PDBORCL                                                READ WRITE
     4 PDBEISOO                                              MOUNTED
     5 PDB3                                                      READ WRITE

SQL> alter pluggable database pdbeisoo open;
alter pluggable database pdbeisoo open

ERROR at line 1:
ORA-01157: cannot identify/lock data file 16 - see DBWR trace file
ORA-01110: data file 16: 'E:\APP\ORCL\ORADATA\ORCL\EISOO\PDBEISOO.DBF'


使用RMAN进行修复：
C:\Users\Administrator>rman target sys/oracle@orcl

RMAN> list failure;

RMAN> advise failure;

RMAN> repair failure;


打开数据库pdbeisoo
SQL> alter pluggable database pdbeisoo open;

Operation 227 succeeded.


验证数据恢复成功
SQL> select count(*) from tb_xs;

  COUNT(*)
