Question 7, 8, 9, 10

Which two are true about the Automatic Database Diagnostic Monitor (ADDM)? (Choose two.)

A. It analyzes a period of time corresponding to the 12 hours of activity.

B. It runs automatically after each AWR snapshot.

C. A DBA can run it manually.

D. Results are written to the alert log.

E. It analyzes a period of time corresponding to the last day of activity.

Correct Answer: BC

A: ADDM analyzes the data collected between two AWR snapshots, which is typically a one-hour period. So 12 hour period is wrong.

B: ADDM runs automatically after each AWR snapshot, which is typically every hour by default.

C: The DBA can also manually run ADDM by calling the sql scripts under rdbms/admin directory. 

D: ADDM is not written to alert log. The results are saved in the database.

E: Not to the last day of activity.

Which two are true about server-generated alerts? (Choose two.)

A. Stateful alerts must be cleared by a DBA after resolving the problem.

B. Stateless alerts can be purged manually from the alert history.

C. Stateless alerts can be cleared manually.

D. Stateless alerts are automatically cleared.

E. Stateful alerts are purged automatically from the alert history.

Correct Answer: BC

The database considers all the non-threshold alerts as stateless alerts. A stateful alert first appears in the DBA_OUTSTANDING_ALERTS view and goes to the DBA_ALERT_HISTORY view when it is cleared. A stateless alert goes straight to DBA_ALERT_HISTORY.(http://www.remote-dba.net)

For metric alert event types, an event (metric alert) is raised based on the metric threshold values. These metric alert events are called stateful alerts. For those metric alert events that are not tied to the state of a monitored system (for example, snapshot too old, or resumable session suspended ), these alerts are called stateless alerts. Because stateless alerts are not cleared automatically, they need to be cleared manually.

D. Users must always input patch plans to opatchauto.

E. It requires the Oracle Grid Infrastructure and Oracle Database instances to be shut down before being invoked.
