You administer an online transaction processing (OLTP) system whose database is stored in Automatic Storage Management (ASM) and whose disk group use normal redundancy.
One of t he ASM disks goes offline, and is then dropped because it was not brought online before DISK_REPAIR_TIME elapsed.
When t he disk is replaced and added back to the disk group, the ensuing rebalance operation is too slow.
Which two recommendations should you make to speed up the rebalance operation if this type of failure happens again?
A. Increase the value of t he ASM_POWER_LIMIT parameter.
B. Set the DISK_REPAIR_TIME disk attribute to a lower value.
C. Specify t he statement that adds the disk back to the disk group.
D. Increase the number of ASMB processes.
E. Increase the number of DBWR_IO_SLAVES in t he ASM instance.
Correct Answer: AD
