Your database is functioning in ARCHIVELOG mode. In which two situations would you perform a cancelbased recovery？（）
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday， at 9：00 a.m. the current log sequence number was 369. Also， on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file （sequence number 356） that contained redo entries between 8：00 a.m. and 8：30 a.m. With reference to this scenario， what would you do to recover the database？（）
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？（）
