QUESTION 52
You conned using SQL Plus to the root container of a multitenant container database (CDB) with SYSDBA privilege.
The CDB has several pluggable databases (PDBs) open in t he read/write mode.
There are ongoing transactions in both t he CDB and PDBs.
What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?
A. The shutdown proceeds immediately.
The shutdown proceeds as soon as all transactions in t he PDBs are either committed or rolledback.
B. The shutdown proceeds as soon as all transactions in t he CDB are either committed or rolledback.
C. The shutdown proceeds as soon as all transactions in both t he CDB and PDBs are either committed or rolled back.
D. The statement results in an error because there are open PDBs.
Correct Answer: B
(解析：一旦 CDB 和 PDB 中的事務(wù)提交和回滾，數(shù)據(jù)庫就會關(guān)閉，這道題考的是命令的生效范圍。)
