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 Oracle Automatic Storage Management (Oracle ASM) instance.
-
In an Oracle Exadata environment, you cannot set this parameter to 0.
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
.
