(Choose all that apply.)
Correct Answer: C,E
Explanation/Reference:
Explanation:
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.
If the number of reusable records in the control file exceeds the circular reuse record limit UB4MAXVAL, then reusable records will be overwritten even if CONTROL_FILE_RECORD_KEEP_TIME has not elapsed.
UB4MAXVAL is defined in the oratypes.h header file, which is found in the public directory. Its value may vary according to the operating system you are using.
