RC_OFFLINE_RANGE

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.

Column	Datatype	Description
`DB_KEY`	`NUMBER`	The primary key for the target database. Use this column to form a join with almost any other catalog view.
`DBINC_KEY`	`NUMBER`	The primary key for the incarnation of the target database. Use this column to form a join with `RC_DATABASE_INCARNATION`.
`DB_NAME`	`VARCHAR2(8)`	The `DB_NAME` of the database incarnation to which this record belongs.
`RECID`	`NUMBER`	The record identifier for the offline range from `V$OFFLINE_RANGE`. `RECID` and `STAMP` form a concatenated primary key that uniquely identifies this record in the target database control file.
`STAMP`	`NUMBER`	The stamp for the offline range from `V$OFFLINE_RANGE`. `RECID` and `STAMP` form a concatenated primary key that uniquely identifies this record in the target database control file.
`FILE#`	`NUMBER`	The absolute file number of the datafile.
`CREATION_CHANGE#`	`NUMBER`	The SCN at datafile creation.
`OFFLINE_CHANGE#`	`NUMBER`	The SCN taken when the datafile was taken offline.
`ONLINE_CHANGE#`	`NUMBER`	The online checkpoint SCN.
`ONLINE_TIME`	`DATE`	The online checkpoint time.
`CF_CREATE_TIME`	`DATE`	The time of control file creation.
