V$OFFLINE_RANGE displays datafile offline information from the control file. Note that the last offline range of each datafile is kept in the DATAFILE record.
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.
