Immediately after adding a new disk to or removing an existing disk from an ASM instance,
you find that the performance of the database goes down initially until the time the addition
or removal process is completed, and then gradually becomes normal. Which two activities
would you perform to maintain a consistent performance of the database while adding or
removing disks? (Choose two.)
A.
Increase the number of slave database writer processes by setting up a higher value for
DBWR_IO_SLAVES.
B.
Increase the number of DBWR processes by setting up a higher value for
DB_WRITER_PROCESSES.
C.
Define the POWER option while adding or removing the disks.
D.
Increase the number of ARB processes by setting up a higher value for
ASM_POWER_LIMIT.
