From the V$SESSION_LONGOPS...

单项选择题From the V$SESSION_LONGOPS view， you find that some of the database users have long-running queries that consume a lot of CPU time. This causes performance problems for other users in the database， who have much shorter queries. You would like to make sure that the users with large queries do not use all the CPU time， but you still do not want to terminate them with an error message. Which method would you follow to achieve this？（）

A. set the CPU time per call in the users profile
B. set the CPU time per session in the users profiles
C. set the TIMED_STATISTICS parameter to TRUE in the parameter file
D. set the CPU levels for the users’ group using Resource Manager

3.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 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.
B. The members of the HIGH_CG consumer group would get 10% of the CPU.
C. The plan PROD_DB_PLAN can have subplans.
D. The CPU allocation for the consumer groups would be based on the ratio defined for the CPU_P1.

4.单项选择题The database is running in ARCHIVELOG mode and the FORMAT option is not configured in RMAN for disk backups. You configured the flash recovery area location and size by using the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE initialization parameters. Which statement is correct in this scenario？（）

A. If the FORMAT option to the RMAN BACKUP command is specified， then RMAN creates backup pieces and image copies in the flash recovery area with names in the Oracle Managed Files （OMF） format.
B. If any local destinations for LOG_ARCHIVE_DEST_n are set， then archived redo logs are stored in these destinations as well as in the flash recovery area.
C. If the flash recovery area location is configured using the DB_RECOVERY_FILE_DEST initialization parameter， then the RMAN backup of Oracle managed datafiles （OMF） only will go to the flash recovery area by default.
D. If no other destination is configured for recovery files， then RMAN places the control file autobackups in the flash recovery area by default.
