C) Perform a direct upgrade by running the Database Upgrade Assistant (DBUA).
D) Perform a rolling upgrade.
E) Install the Oracle Database 12c software, create a new Oracle 12c database, and then use the Oracle Data Pump to import data from the source Oracle 9i database to the target Oracle 12c database.
Answer：BE
(解析：這道題考的升級的內容挺深的，有些內容故意打亂順序，混淆視聽。
A答案應該是先以升級方式啟動數據庫，然後再執行那兩個腳本。
B答案對是因為9i的數據庫不能直接升級到12c，需要先升級到10.2.0.5，然後再升級到12c。
C答案就不用說了，肯定不行。
D答案說的比較籠統，沒有具體說出升級方式。
E答案是比較清晰的答案，可以把數據庫通過導出導入方式進行升級。
