CONTROL_FILE_RECORD_KEEP_TIME

Property Description
Parameter type Integer
Default value 7 (days)
Modifiable ALTER SYSTEM
Range of values 0 to 365 (days)
Basic No

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.

Note:

This parameter applies only to records in the control file that are circularly reusable (such as archive log records and various backup records). It does not apply to records such as datafile, tablespace, and redo thread records, which are never reused unless the corresponding object is dropped from the tablespace.
