QUESTION 16
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)
Correct Answer: A

因为在你的生产数据库逻辑损坏，你想做点
在恢复时间（不完全恢复）。但是在你开始恢复之前，你就开始了
ts_pitr_objects_to_be_dropped查看，发现有大量的对象，
当你开始用这个方法恢复的时候会被丢弃。你想保存这些对象。
该选项必须使用执行不完全恢复和保护对象？

A.在执行TSPITR前 先分别做导出、导入操作
