Upgrade Oracle DBA 11g to Oracle Database 12c — Question 8

While performing database backup to tape via the media manager interface, you notice that tape streaming is not happening because RMAN is not sending data blocks fast enough to the tape drive.
Which two actions would you take for tape streaming to happen during the backup?

Answer options

• A. Configure backup optimization.
• B. Configure the channel to increase maxopenfiles.
• C. Configure a backup policy by using incremental backups.
• D. Configure the channel to increase capacity with the rate parameter.
• E. Configure the channel to adjust the tape buffer size by using the 3LKSIZE option.
• F. Configure large_pool, if not done already. Alternatively, you can increase the size of
• G. LARGE_POOL.

Correct answer: A, D

Explanation

The correct actions are A and D. Configuring backup optimization (A) helps minimize unnecessary data being backed up, which can improve streaming efficiency. Increasing the capacity with the rate parameter (D) allows for more data to be sent to the tape drive faster. The other options either do not directly affect streaming or do not address the issue of data transmission rate.
