CONTROL_FILE_RECORD_KEEP_TIME

Parameter type	Integer
Default value	7 (days)
Parameter class	Dynamic: ALTER SYSTEM
Range of values	0 to 365 (days)

CONTROL_FILE_RECORD_KEEP_TIME specifies the minimum number of days before a reusable record in the control file can be reused. In the event a new record needs to be added to a reusable section and the oldest record has not aged enough, the record section expands. If this parameter is set to 0, then reusable sections never expand, and records are reused as needed.
