Examine the values for the following initialization parameters:
FAST_START_MTTR_TARGET = 0
LOG_CHECKPOINT_INTERVAL = 0
Which two will be the implications of these values in your database? (Choose two.)
A.The SGA advisor will be disabled.
B.The MTTR advisor will be disabled .
C.Automatic checkpoint tuning will be disabled.
D.Checkpoint information will not be written to the alert log file
如果将FAST_START_MTTR_TARGET设置为0将关闭检查点自动调整功能。当设定一个大于0的值给FAST_START_MTTR_TARGET，则自动调整检查点功能将启用。
启用 MTTR Advisor 需要设置 STATISTICS_LEVEL 和 FAST_START_MTTR_TARGET。
