OCP题目关于CONTROL_FILE_RECORD_KEEP_TIME ,发现答案和官方文档的解释,有出入,
You set the value for the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter to 7.
Which two records in the control file of the database are circularly reused for storage because of
using this parameter?(Choose two.)
选项
A.
backup records
B.
data file records
C.
archive log records
D.
tablespace records
E.
redo thread records
C E
注释：官方文档结解释如下：
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.
