第4题:
You executed the following PL/SQL block successfully: VARIABLE tname VARCHAR2(20) BEGIN dbms_addm.insert_finding_directive (NULL, DIR_NAME=>’Detail CPU Usage’, FINDING_NAME=>’CPU Usage’, MIN_ACTIVE_SESSIONS=>0, MIN_PERC_IMPACT=>90); :tname := ’database ADDM task4’; dbms_addm.analyze_db(:tname, 150, 162); END; / Then you executed the following command: SQL> SELECT dbms_addm.get_report(:tname) FROM DUAL; The above command produces Automatic Database Diagnostic Monitor (ADDM) analysis()

第8题:
Your database is functional with a peak load for the last one hour. You want to preserve the performancestatistics collected during this period to be used for comparison when you analyze the performance of thedatabase in the future. What action would you take to achieve this task()
第9题:
You create a new Automatic Database Diagnostic Monitor (ADDM) task: instance_analysis_mode_task. To view the ADDM report, you use the following command: SQL> SELECT dbms_addm.get_report(’my_instance_analysis_mode_task’) FROM dual; You want to suppress ADDM output relating to Segment Advisor actions on user SCOTT’s segments. What would you do to achieve this?()
第10题:
The ADDM requires at least four AWR snapshots for analysis.
The ADDM runs after each AWR snapshot is collected automatically by MMON.
The results of the ADDM analysis are stored in the Automatic Workload Repository (AWR).
The ADDM analysis provides only diagnostic information but does not provide recommendations.
The ADDM calls other advisors if required, but does not provide recommendations about the advisors.
第11题:
All AWR tables belong to the SYSTEM schema.
The AWR contains systemwide tracing and logging information.
The snapshots collected by the AWR are accessible through data dictionary views.
The snapshots collected by the AWR are used by self-tuning components in the database.
第12题:
Create two custom ADDM tasks.
Modify the AWR snapshot time interval to two hours.
Create a new scheduler window for a time period of two hours.
Modify the Automatic Workload Repository (AWR) snapshot retention period to two hours.
第13题:
Your database is functional with a peak load for the last one hour. You want to preserve theperformance statistics collected during this period to be used for comparison when you analyze theperformance of the database in the future. What action would you take to achieve this task()
