Oracle Database 12c: Installation and Administration — Question 233

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 tape drive fast enough.
What could be a solution to make streaming happen during the backup?

Answer options

• 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

Correct answer: D

Explanation

The correct answer is D because adjusting the tape buffer size with the BLKSIZE option can enhance the efficiency of data transfer to the tape drive, enabling better streaming. Options A, B, and C do not directly address the issue of tape streaming, as they focus on backup optimization, file handling, and transfer rates, which do not inherently resolve the problem of buffering in this context.
