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 UNTIL SEQUENCE 230 THREAD 1; 3> ALTER DATABASE MOUNT; 4> RESTORE DATABASE; 5> RECOVER DATABASE; 6> ALTER DATABASE OPEN RESETLOGS;7> }; With reference to this scenario, which statement is true?()
The current time is 12:00 noon. You want to recover the USERS tablespace from a failure that occurred at 11:50 a.m. You discover that the only member of an unarchived redo log group containing information from 11:40 a.m. onwards is corrupt. With reference to this scenario, if you are not using Recovery Manager (RMAN), which recovery method would you use?()
