题库中原题为：

707.Because of a logical corruption in the EMPLOYES tables, you want to perform Tablespace
Point-in-Time Recovery (TSPITR) to recover the table. Before you started the TSPITR process, you
queried the TS_PITR_CHECK view and you realized that the table has a referential constraint with
DEPARTMENTS that exists in another tablespace, MASTERTBS.
Which two actions will permit the TSPITR to work? (Choose two.)
A.Taking the MASTERTBS tablespace offline
B.Dropping the relationship between the tables
C.Adding the MASTERTBS tablespace to the recovery set
D.Putting the MASTERTBS tablespace in read-only mode
Answer:AD

争议点：
网上有人说选择BC，比如“标记为正确答案，不看answer版”题库。

比如：
Riveore的解析：http://blog.csdn.net/rlhua/article/details/19844311
LuiseDalian的解析：http://blog.itpub.net/17013648/viewspace-1349677/

本题考查 TSPITR 。
题库答案明显错了。AD的操作根本对于执行此次TSPITR操作毫无作用。

初步结论：
选择BC。
