Users are performing a large volume of inserts and deletes on the application tables in the APPS tablespace. You observe that there are several warning alerts being generated for the APPS tablespace space usage metrics. Currently， the warning threshold for the tablespace space usage metrics is set to 70%.
To make the generated alerts more useful as a problem identification tool， you want to reduce the frequency of alert generation for the tablespace space usage metrics for the APPS tablespace. What should you do？（）
A.disable SQL tracing for theAPPS tablespace
B.disable logging attribute for the APPS tablespace
C.modify the tablespace to be a dictionarymanaged tablespace
D.increase the critical threshold value for the tablespace space usage metrics for the APPS tablespace
E.increase the warning threshold value for the tablespace space usage metrics for the APPS tablespace
A.the alert log file
B.the core dump files
C.the change tracking file
D.the user session trace files
E.the database audit trail files
F.the background process trace files
In your test database， you find that a user’s session is executing a lot of SQL statements， resulting in the generation of a large number of trace files. While investigating the reason， you find that SQL trace has been enabled at the instance level.
You want to disable SQL trace， remotely， only for that user session to reduce the volume of trace data being generated.
How do you achieve this objective？（）
A.by setting the SQL_TRACE parameter to FALSE in the parameter file
B.by using DBMS_MONITOR.SESSION_TRACE_DISABLE to disable the tracing for the user session
C.by setting the SQL_TRACE parameter to FALSE by using the ALTER SYSTEM command in the user session
D.by setting the SQL_TRACE parameter to FALSE by using the ALTER SESSION command in the user session
A.fixed views
B.the alert log file
C.the parameter file
D.the server parameter file
E.dynamic performance views
The backup retention policy is configured as RECOVERY WINDOW 2. You executed the following command in Recovery Manager （RMAN） against your database：

B.a list of all those files that have been deleted in the last two days
C.a list of all those files that have been recovered within the last two days
D.a list of backups and copies that are outside the range covered by the current retention policy
A.backups that can be deleted
B.stored scripts in the recovery catalog
C.backup sets and image copies that are obsolete
D.only the most recent backup sets or image copies
E.backups that do not have the AVAILABLE status in RMAN repository
You executed the following command in Recovery Manager （RMAN） against your Oracle 10g database：
RMAN> REPORT NEED BACKUP days 3;
What would be the output of this command？（）
A.a list of files that require a backup within three days
B.a list of files that have not been backed up for three days
C.a list of files that RMAN recommends be backed up only once in every three days， based on low volatility
D.a list of files for which a backup has already been performed and may need a backup after three days
A.data file
B.password file
C.archivelog file
D.temporary file
E.online redo log file
F.the current control file
G.the tnsnames.ora file
H.current server parameter file
Your database is functioning in NOARCHIVELOG mode. Your database contains 15 tablespaces. You want to use Recovery Manager （RMAN） to perform backups.

A.backup of offline tablespaces
B.backup of readonly tablespaces
C.backup of systemcritical tablespaces
D.backup of online， locally managed tablespaces
E.backup of read/write dictionarymanaged tablespaces
View the Exhibit.
You executed the following command to perform a backup of the USERS tablespace：
RMAN> BACKUP
TABLESPACE USERS;
Which three types of files are backed up？ （）
A.password file
B.online redo log files
C.the current control file
D.archived redo log files

Consider the recovery steps in each of the cases given below： Case 1： Shut down the database and perform a backup. Restore all the data files. Mount the database. Recover the database. Without applying all the redo log files， open the database using the RESETLOGS option. Back up the database. Case 2： Shut down the database and perform a backup. Restore only the data files of the tablespace where user error damaged the data. Mount the database. Recover the database. Open the database with the RESETLOGS option. Back up the database. Case 3：Shut down the database Restore the data files Open the database Perform recovery to the current point in time. Which case has the correct steps for an incomplete recovery？（）
On Tuesday， a junior DBA dropped an important application user account， whose schema has important tables. You are asked to recover all the objects in the schema. On investigation， you find that the user account was dropped at 11：00 a.m. and Sunday’s backup is the most recent backup. Which flashback feature would you use？（）
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday， at 9：00 a.m. the current log sequence number was 369. Also， on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file （sequence number 356） that contained redo entries between 8：00 a.m. and 8：30 a.m. With reference to this scenario， what would you do to recover the database？（）
