A customer is planning a new database rollout using Oracle and wants to perform online backups.
Initial tests with NetWorker have shown that the backups cannot be completed within the backup
window of 6 hours.
You have analyzed your backup environment and there are adequate resources to meet this
stringent backup window. What is one of the first things to check in NetWorker or RMAN to

increase performance without adding cost and complexity?

A.
Adjust the maximum number of files in a backup set to be less than the number of open files

B.
Adjust RMAN channels to have multiple streams per tape device

C.
Adjust RMAN multiplexing to be less than the tape multiplexing setting

D.
Adjust RMAN multiplexing to be equal to or greater than the tape multiplexing setting
