46. Which two statements are true about the Automatic Database Diagnostic Monitor (ADDM)? (Choose
two.)
A.The ADDM requires at least four AWR snapshots for analysis.
B.The ADDM runs after each AWR snapshot is collected automatically by MMON.
C.The results of the ADDM analysis are stored in the Automatic Workload Repository (AWR).
D.The ADDM analysis provides only diagnostic information but does not provide recommendations.
E.The ADDM calls other advisors if required, but does not provide recommendations about the advisors.
Answer: BC
答案解析：
ADDM 在记录每个AWR 快照之后会自动运行。每次记录快照后，ADDM 会分析与最后两个快照对应的时段。ADDM 会预先监视实例，以便在大多数瓶颈问题成为严重问题之前检测到这些问题。多数情况下，ADDM 会为检测到的问题提供建议解决方案，甚至可以量化这些建议的优势。
