While creating a scheduler window using the DBMS_SCHEDULER package， a user logged in as DBMGR gets the error message insufficient privileges. 
Which two commands would you use to resolve this error？（）

单项选择题In your production database there is a job， CALC_STAT， which has been scheduled to run every Friday at 5：00 p.m. CALC_STAT updates the optimizer statistics for the objects owned by the APPS schema. You want the task to be generic， thereby allowing users to modify the attributes of the task at run time without affecting the original task. Which component of Oracle Scheduler must you define to achieve this？（）

A.Window
B.Program
C.Job class
D.Window group

单项选择题Your business has departmental reports that are generated every day. Each department must use the same set of queries， but accesses a different subset of data in the tables， depending on which department generates the report. The format of the reports is being developed currently， the format changes daily.  How would you configure the database to ensure that each department generates its report （based on its target data） using the most recent report format every day？（）

A.by having each user run the report generation procedure at the scheduled time， supplying the necessary input variables
B.by creating a program using DBMS_JOB that accepts one or more variables， and creating a job that calls this program using DBMS_JOB
C.by having each user schedule a job using DBMS_JOB that accepts one or more input variables and calls a procedure that generates the report
D.by having each user create a job using DBMS_SCHEDULER that includes all the information and commands necessary to generate the report
E.by creating a program using DBMS_SCHEDULER that accepts one or more variables， and creating a job that calls this program using DBMS_SCHEDULER

A.The parallel degree limit for DB_GRP will be the minimum of all the incoming values.
B.The parallel degree limit for DB_GRP will be the maximum of all the incoming values.
C.The maximum estimated execution time for DB_GRP would be the most nonrestrictive of all incoming values.
D.If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would not execute if the active session pool for the new consumer group was full.
E.If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would execute even if the active session pool for the new consumer group was full.

多项选择题You have created a resource plan， PROD_DB_PLAN， with the following consumer groups with the respective plan directives：  Consumer group SALES with CPU_P1 as 60 and DEGREE_OF_PARALLELISM as 4. Consumer group MARKET with CPU_P1 as 20.  Consumer group DEV with CPU_P1 as 20.  Consumer group OTHERS with CPU_P1 as 0 and CPU_P2 as 100.  Which two statements are correct in this scenario？ （）

A.The maximum degree of parallelism for the members of the consumer groups is 4.
B.The CPU allocation will always be equal for the consumer groups MARKET and DEV.
C.The OTHERS consumer group would get 100% of the CPU if there are unused level 1 CPU resources.
D.The SALES and MARKET consumer groups would get 100% of the CPU if there are unused level 2 CPU resources.
E.The maximum degree of parallelism for the members of the consumer group SALES is 4 with no restriction for the remaining groups.

单项选择题You have created a resource plan， PROD_DB_PLAN， that uses the RATIO policy. The following consumer groups and their respective plan directives have been assigned to this resource plan： Consumer group HIGH_CG with CPU_P1 as 10.  Consumer group MEDIUM_CG with CPU_P1 as 5.  Consumer group LOW_CG with CPU_P1 as 2.  Consumer group OTHER_GROUPS with CPU_P1 as 1.  Which statement is correct in this scenario？（）

A.The plan PROD_DB_PLAN can have subplans.
B.The members of the HIGH_CG consumer group would get 10% of the CPU.
C.The CPU allocation for the consumer groups would be based on the ratio defined for the CPU_P1.
D.The CPU allocation would be equal between the HIGH_CG and MEDIUM_CG consumer groups if there are no sessions existing for the LOW_CG and OTHER_GROUPS consumer groups.
