191: You are using an Automatic Storage Management (ASM) instance to
manage the database files of your production database. After adding a new
disk group to the ASM instance, you execute the following
command: ALTER DISKGROUP dg3 REBALANCE POWER 0;
What would be the result of this command?
A.The rebalancing of the disk group would be stopped.
B.The rebalancing of the disk group would be completed as fast as possible.
C.The command would result in an error because the value of POWER cannot
be 0.
D.The rebalancing of the disk group would be completed without affecting
the disk group DG3.
E.The command would result in an error because the disk groups cannot be
manually rebalanced.
Answer: A
Oracle通过一个新增的参数:asm_power_limit 来控制速度。
该参数取值范围为1~11,参数值越大平衡速度越快。
如果为0会停止?需试验
