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 optimization
- B、Configure the channel to increase MAXOPENFILES
- C、Configure the channel to increase the capacity with the RATE parameter
- D、Configure the channel to adjust the tape buffer size with the BLKSIZE option

单选题You are the network administrator for The network consists of a single Active Directory domain All network servers run Windows Server 2003. One member server hosts a folder named F:/TestKingData. Thousands of users constantly request and updates files in F:/TestKingData. You use the Backup utility to perform an incremental backup of F:/TestKingData on magnetic tape. The backup completes normally, but you see an error indicator illuminated on the tape server. You need to verify that you can restore F:/TestKingData from the backup tape. The verification process must not affect existing files. What should you do?（）A
In the Backup utility, use the Restore and Manage Media tab to select the original tape media. Ensure that files will be restored to their original location. Start the restoration and verify that all files are restored successfully.B
