The BACKUP_TAPE_IO_SLAVES parameter is set to FALSE for the database instance. Which statement is true while performing a tape backup in an RMAN session?()
A. The tape I/O performed is asynchronousB. The tape buffer is allocated from the System Global Area (SGA)C. The tape buffer is allocated from the Program Global Area (PGA)D. Oracle I/O uses an interrupt mechanism to determine when each I/O completes
考题
