第10题：

You are creating a job class. You have issued the following command to create the job class：  SQL> BEGIN   DBMS_SCHEDULER.CREATE_JOB_CLASS（        JOB_CLASS_NAME => ’LOW_PRIORITY_CLASS’，        RESOURCE_CONSUMER_GROUP => ’LOW_GROUP’，        LOGGING_LEVEL => DBMS_SCHEDULER.LOGGING_FULL，        LOG_HISTORY => 1200，   COMMENTS => ’LOW JOB PRIORITY CLASS’）；        END；        SQL> /   What will be the result of the above command？（）

• A、 The command will be executed successfully.
• B、 The command will fail because RESOURCE_CONSUMER_GROUP is an invalid parameter in the  DBMS_SCHEDULER.CREATE_JOB_CLASS procedure.
• C、 The command will fail because LOGGING_LEVEL is an invalid parameter in the DBMS_SCHEDULER.CREATE_JOB_CLASS procedure.
• D、 The command will fail because LOG_HISTORY is an invalid parameter in the DBMS_SCHEDULER.CREATE_JOB_CLASS procedure.
• E、 The command will fail because 1200 is an invalid value for the LOG_HISTORY parameter in the  DBMS_SCHEDULER.CREATE_JOB_CLASS procedure.
