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.

Which three are true about the large pool for an Oracle database instance that supports shared serverconnections?() A. Allocates memory for RMAN backup and restore operationsB. Allocates memory for shared and private SQL areasC. Contains a cursor area for storing runtime information about cursorsD. Contains stack spaceE. Contains a hash area performing hash joins of tables
You noticed that large memory allocations for the Oracle backup and restore operations are causing a performance overhead on the shared pool. Which memory structure would you configure to avoid this performance overhead?()A、 recycle buffer cacheB、 large poolC、 streams poolD、 keep buffer cacheE、 redo log buffer
Redo log files are multiplexed in your database. The disk in which you have one of the redo log members is highly fragmented. In the process of defragmentation you lose the redo log member, which is not a member of the current group. How would you recover from the loss of the redo log member?()A、SMON would automatically restore the lost file.B、You would need to restore the whole database from the last backup.C、You would need to restore the file from the last full database backup.D、You would need to use flashback technology to restore the lost redo log member.E、You would need to use Recovery Manager (RMAN) to restore the lost redo log member.F、You would need to restore the missing log file by copying one of the remaining files from the same group.
