ASM_POWER_LIMIT

Property Description
Parameter type Integer
Default value 1
Modifiable ALTER SESSION, ALTER SYSTEM
Range of values 0 to 11Foot 1 
Oracle RAC Multiple instances can have different values.

Footnote 1 Beginning with Oracle Database 11g Release 2 (11.2.0.2), if the COMPATIBLE.ASM disk group attribute is set to 11.2.0.2 or higher, then the range of values is 0 to 1024.

Note:

This parameter may only be specified in an Automatic Storage Management instance.

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.
