QUESTION NO: 504

Your database is in ARCHIVELOG mode. You have two online redo log groups, each of which contains one
redo member. When you attempt to start the database, you receive the following errors:
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: ‘D:\REDO01.LOG’
You discover that the online redo log file of the current redo group is corrupted. （表示数据库未归档， current
redo log 不能归档） Which statement should you use to resolve this issue?

A. ALTER DATABASE DROP LOGFILE GROUP 1;
B.ALTER DATABASE CLEAR LOGFILE GROUP 1;（对非归档模式）
C. ALTER DATABASE CLEAR UNARCHIVED LOGFILE GROUP 1;
D. ALTER DATABASE DROP LOGFILE MEMBER ‘D:\REDO01.LOG’;
Answer: C
