A. Flashback Data Archive

B. Flashback logs in the flash recovery area

C. FlashbUndo tablespace

D. RMAN command line

E. None of the above

Undo tablespace are not required. The RMAN command line is not required to recover to a flashback

point; the DBA can execute the Flashback Database command from within SQL Plus.

闪回数据库依赖哪个技术以恢复到某个时间点？

B.闪回恢复区中闪回日志

闪回数据库依赖闪回恢复区中的闪回日志。 闪回数据归档和UNDO表空间不是必需的。 RMAN命令行不是恢复到一个闪回点

所必需的。 DBA可以在SQL Plus中执行闪回数据库命令。
