1. 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 enabled.

C.Automatic checkpoint tuning will be disabled.

D.Checkpoint information will not be written to the alert log file. 

Answer: BC

官方文件上說開啟MTTR Advisor 的操作如下

10.5.3.3.1 Enabling MTTR Advisor

To enable MTTR Advisor, set the two initialization parameters STATISTICS_LEVEL and FAST_START_MTTR_TARGET.

STATISTICS_LEVEL governs whether all advisors are enabled and is not specific to MTTR Advisor. Ensure that it is set to TYPICAL or ALL. Then, when FAST_START_MTTR_TARGET is set to a nonzero value, the MTTR Advisor is enabled.

現在上面的FAST_START_MTTR_TARGET = 0 那麼mttr advisor能enable嗎
