Because of a logical corruption in your production database, you wanted to perform Tablespace Point in Time Recovery (TSPITR). But before you start the recovery, you queried the
TS_PITR_OBJECTS_TO_BE_DROPPED view and realized that there are a large number of objects that would be dropped when you start the recovery by using this method. You want to preserve these objects.
Which option must you use to perform TSPITR and preserve the object?
A. Perform Export before TSPITR and Import after TSPITR
B. Move objects to another schema that has the same tablespace assigned
C. Perform Incomplete Recovery before TSPITR with the Log Sequence Number (LSN)
D. Perform Incomplete Recovery before TSPITR with the System Change Number (SCN)
此题的意思是，想回退某个表空间，但是有一部分受影响（会 drop）的表想保留。那么只能通过导出的方式保留表，然后再导入
首先排除 C.D，进行不完全恢复的话，是数据库级别的回退，那么所有的对象都会影响，当然 TSPITR 的对象也无法保障。
C 选项错误，移动后还是在相同的表空间，仍然会被 drop。
