考题 Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?()A. Configure backup optimizationB. Configure the channel to increase MAXOPENFILESC. Configure the channel to increase the capacity with the RATE parameterD. Configure the channel to adjust the tape buffer size with the BLKSIZE option
