You have joined a new organization as a Database Administrator. The Security Administrator in your organization has kept human errors， such as erroneously dropping users， tables， and important data， to a minimum by carefully granting only the necessary privileges to each user. As a result of several ongoing transactions within your database， you discover that the flashback logs are rapidly increasing in the flash recovery area. To avoid out-of-space errors， you decide to delete the flashback logs from the flash recovery area. How can you delete the flashback logs from the database if your database is up and running？（）
A
Shut down the database using the SHUTDOWN command. Mount the database using the STARTUP MOUNT EXCLUSIVE command and disable Flashback Database using the ALTER DATABASE FLASHBACK OFF statement.
B
Change the parameter setting in the SPFILE for the DB_RECOVERY_FILE_DEST parameter using the ALTER SYSTEM SET DB_RECOVERY_FILE_DEST=’’ SCOPE=BOTH statement while the database is up and running.
C
Shut down the database using the SHUTDOWN command. Mount the database using the STARTUP MOUNT EXCLUSIVE command. Change the parameter setting in the SPFILE for the DB_RECOVERY_FILE_DEST parameter using the ALTER SYSTEM SET DB_RECOVERY_FILE_DEST=’’ SCOPE=BOTH statement. Disable Flashback Database using the ALTER DATABASE FLASHBACK OFF statement.
D
Change the parameter setting in the SPFILE for the DB_RECOVERY_FILE_DEST parameter using the ALTER SYSTEM SET DB_RECOVERY_FILE_DEST=’’ SCOPE=BOTH statement. Shut down the database using the SHUTDOWN command. Mount the database using the STARTUP MOUNT EXCLUSIVE command and disable Flashback Database using the ALTER DATABASE FLASHBACK OFF statement.

单选题For 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 profile.C
Set the CPU levels for the user’s group using Resource Manager.D
Set the TIMED_STATISTICS parameter to TRUE in the parameter file.

by setting the SQL_TRACE parameter to FALSE in the parameter fileB
by using DBMS_MONITOR.SESSION_TRACE_DISABLE to disable the tracing for the user sessionC
by setting the SQL_TRACE parameter to FALSE by using the ALTER SYSTEM command in the user sessionD
by setting the SQL_TRACE parameter to FALSE by using the ALTER SESSION command in the user session
