官方英文解释

In an Oracle Automatic Storage Management (Oracle ASM) instance, V$ASM_OPERATION displays one row for every active Oracle ASM long running operation executing in the Oracle ASM instance.

Disk group number (primary key). This is the foreign key to the V$ASM_DISKGROUP view.

Starting with Oracle Database 12c, new queries should use the PASS column instead of this column.

COMPACT Oracle ASM is moving user data closer together, which improves performance by reducing seek distance

PREPARE Completing work corresponding to the prepare SQL operation. This phase is enabled only for FLEX or EXTENDED redundancy disk groups and COMPATIBLE.ASM must be set to 12.2 or higher.

REBUILD Restoring the redundancy of forcing disks. Forcing disks are those disks that have been dropped with the FORCE option.

RESILVER This value appears in Oracle Exadata environments when WriteBack FlashCache is enabled

RESYNC Resync operation in progress to bring one or more Oracle ASM disks online

Starting with Oracle Database 12c, new queries should use this column instead of the OPERATION column.

Estimates are computed in parallel in the background while the work is being executed. Thus, the transition from the EST to the RUN state may be extremely fast.

Power requested for the operation as specified by the ASM_POWER_LIMIT initialization parameter or command syntax. Or, power requested for the operation as specified by the power option of the scrubbing SQL syntax.

Number of Allocation Units that are being moved per minute by the operation. Or, the number of Allocation Units that have been scrubbed so far.

Estimated number of Allocation Units that have to be moved by the operation. Or, the estimated number of Allocation Units that have to be scrubbed by the scrubbing operation.

Estimated number of Allocation Units that are being moved per minute by the operation

Estimated amount of time (in minutes) that the remainder of the operation is expected to take

0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.
