CONTROL_FILE_RECORD_KEEP_TIME

Synopsis

Value: 0-365

Default: 7

Dynamic: ALTER SYSTEM

Specifies the minimum age, in days, that a record in the circularly reusable section of the control file must be before it can be reused. If 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. The names of the reusable sections of the control file are:
