Identify the channel settings that can be performed using the CONFIGURE CHANNEL or
ALLOCATE CHANNEL commands in RMAN. (choose all that apply)
A.
Limiting the input/output (I/O) bandwidth consumption
B.
Specifying the size of backup sets and backup pieces
C.
Specifying vendor-specific information for a media manager
D.
Specifying the parallelism for backup and restore operations
Explanation:
For Limiting the I/O bandwith: CONFIGURE [| ALLOCATE] CHANNEL….RATE
For limiting backup pieces: CONFIGURE [| ALLOCATE] CHANNEL….MAXPIECESIZE
For backup sets, you need to use BACKUP..MAXSETSIZE command to limit!
For parallelism, either to use CONFIGURE DEVICE TYPE..PARALLELISM or to allocate
multiple channels during job. NOT to be done with CONFIGURE CHANNEL.

Vendor-specific information: Use the PARMS channel parameter to specify vendor-specific information for a media manager. You can also use the SEND command to send vendor-specific commands to a media manager.
