一直以为ASM_POWER_LIMIT是越小速度越快,但其实是越大速度越快拉。。

 

ASM_POWER_LIMIT specifies the maximum power on an Automatic Storage Management instance for disk rebalancing. The higher the limit, the faster rebalancing will complete. Lower values will take longer, but consume fewer processing and I/O resources.
 
If the POWER clause of a rebalance operation is not specified, then the default power will be the value of ASM_POWER_LIMIT.
