【oracle】oracledba11 drop the lost member from the database and then add a new mem ber to the group
In your database, online redo log files are multiplexed and one of the
members in a group is lost due to media failure?
How would you recover the lost redo log member?
A.import the database from the last export
B.restore all the members in the group from the last backup
C.drop the lost member from the database and then add a new mem ber to the
group
D.restore all the database files from the backup and then perform a
complete recovery
E.restore all the database files from the backup and then perform an
incomplete recovery
Answer: C
Redo group 里如果有多个成员,那么他们是冗余的。 每个成员里的内容都
一样,所以删除再添加一个即可。
