通过恢复目录（Catalogue）进行PDB级别的PITR恢复

连接 CDBOCP：PDB1 将表空间脱机

SQL> alter session set container=pdb1;

Session altered.

SQL> alter tablespace askscuti offline; alter tablespace askscuti offline
*
ERROR at line 1:
ORA-01191: file 44 is already offline - cannot do a normal offline
ORA-01111: name for data file 44 is unknown - rename to correct file
ORA-01110: data file 44: ‘/u01/app/oracle/product/12.2.0/db_1/dbs/MISSING00044‘

更新控制文件中记录的数据文件信息

SQL> alter database rename file ‘/u01/app/oracle/product/12.2.0/db_1/dbs/MISSING00044‘ to ‘/u01/app/oracle/oradata/CDBOCP/PDB1/askscuti01.dbf‘;

Database altered.

再次对 44 号文件进行单独还原和恢复

RMAN> run{
restore datafile 44;
recover datafile 44;
}

Starting restore at 2019-08-04 13:01:07

datafile 44 is already restored to file /u01/app/oracle/oradata/CDBOCP/PDB1/askscuti01.dbf
restore not done; all files read only,offline,excluded,or already restored

将 CDBOCP：PDB1 表空间联机

SQL> alter tablespace askscuti online;

Tablespace altered.

所以采用 Catalogue 针对 PDB 级别进行 PITR - 可以恢复出被DROP的表空间。
