Immediately after adding a new disk to or removing an existing disk from an Automatic Storage
Management (ASM) instance, you find that the performance of the database decreases initially,
until the addition or removal process is completed. Performance then gradually returns to normal
levels. Which two activities could you perform to maintain a consistent performance of the
database while adding or removing disks? (Choose two.)
A.
increase the number of checkpoint processes
B.
define the POWER option while adding or removing the disks
C.
increase the number of DBWR processes by setting up a higher value for
DB_WRITER_PROCESSES
D.
increase the number of slave database writer processes by setting up a higher value for
DBWR_IO_SLAVES
E.
increase the number of ASM Rebalance processes by setting up a higher value for
ASM_POWER_LIMIT during the disk addition or removal
