This view lists the offline ranges for datafiles. It corresponds to the V$OFFLINE_RANGE
view.
An offline range is created for a datafile when its tablespace is first altered to be offline normal or read-only, and then subsequently altered to be online or read/write. Note that no offline range is created if the datafile itself is altered to be offline or if the tablespace is altered to be offline immediate.
