QUESTION 86
Your database operates in ARCHIVELOG mode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence, 230, is not archived and it contained information from 10:35 a.m.onwards.
The current time is 11:00 a.m. Because of a disk crash, you executed the following command to perform an incomplete recovery:
RMAN> RUN {
2> SET UNIT SEQUENCE 230 THREAD 1;
3> ALTER DATABASE MOUNT;
4> RESTORE DATABASE;
5> RECOVER DATABASE;
6> ALTER DATABASE OPEN RESTLOGS;
7> };
With reference to this scenario, which statement is true?

B. RMAN returns an error because the log sequence number mentioned in the command should be 229.
C. RMAN returns an error because the log sequence number mentioned in the command may never be missing.
