题目
单选题
The warning level threshold value for a tablespace， DATA1， is set to 60% and the critical level threshold value is set to 80%. The tablespace， DATA1， is infrequently used and is not a part of the production environment. You issued the following command：        SQL> EXECUTE   DBMS_SERVER_ALERT.SET_THRESHOLD        （dbms_server_alert.tablespace_pct_full，        dbms_server_alert.operator_ge，80，        dbms_server_alert.operator_ge，90，        1，1，NULL，   dbms_server_alert.object_type_tablespace，’DATA’）；   What will be the result of the command？（）
A

 The command will be executed successfully only if the tablespace DATA1 is a dictionary-managed tablespace.

B

 The total numbers of alerts that you receive every day will be reduced.

C

 The total number of alerts that you receive every day will be increased.

D

 No more data will be added to the DATA1 tablespace if 80% of the space allocated to the DATA1 tablespace is used.

第1题：

You have specified the warning and critical threshold values of an application tablespace to be 60% and 70% respectively. From the tablespace space usage metrics， you find that the actual space usage has reached the specified warning threshold value， but no alerts have been generated. What could be the reason for this？（）

  • A、 The EVENT parameter was not set
  • B、 The SQL_TRACE parameter is set to FALSE
  • C、 The Enterprise Manager Grid Control is not used

第4题：

You are maintaining your OLTP database in Oracle10g. You have not set the warning level and critical level threshold values for space usage of the DATA1 tablespace. What will be the impact？（）

  • A、 No warning level or critical level alert will be generated.
  • B、 A warning level alert will never be generated， but a critical level alert will be generated when 97 percent space of the DATA1 tablespace is used.
  • C、 A critical level alert will never be generated， but a warning level alert will be generated when 85 percent space of the DATA1 tablespace is used.
  • D、 A warning level alert will be generated at 85 percent space usage of the DATA1 tablespace， and a critical level alert is generated at 97 percent space usage of the DATA1 tablespace.

第5题：

You have created a locally managed tablespace by issuing the following command：        CREATE TABLESPACE data1   DATAFILE ’data1_file1.dbf’ SIZE 10M AUTOEXTEND ON MAXSIZE        UNLIMITED；   For the DATA1 tablespace， you have set the warning level alert limit to 70 percent.  In which situation will a warning level alert be generated？（）  

  • A、 when 700 KB is used

第6题：

The warning and critical threshold values have been set to 85% and 97%， respectively， for one of the tablespaces. The current tablespace space usage is 54%. You modify the warning threshold to be 50 % and critical threshold to be 53% in Database Control. Which statement is true？（）

  • A、 The new setting would be applied but no alerts would be raised immediately.
