You lost the index tablespace in your database. You decided to recreate the index tablespace and the indexes in the tablespace.
What methods can you use to recreate the indexes？（）
A.Data Pump
B.SQL scripts
C.SQL*Loader
D.Flashback database
E.Recovery Manager （RMAN） script
A.The index tablespace contains bitmap indexes.
B.The index tablespace contains more than one data file.
C.The index tablespace supports only complete recovery.
D.The index tablespace is not a dictionarymanaged tablespace.
E.There is a dependency relationship between a table and its indexes.
In your database， online redo log files are multiplexed and one of the members in a group is lost due to media failure.
How would you recover the lost redo log member？（）
A.import the database from the last export
B.restore all the members in the group from the last backup
C.drop the lost member from the database， and then add a new member to the group
D.restore all the database files from the backup， and then perform a complete recovery
E.restore all the database files from the backup， and then perform an incomplete recovery
A user executes a query on the EMP table， which contains thousands of rows， to get details about employees in one of the departments. The user receives the following error： SQL> SELECT ename FROM emp WHERE deptno=10 ORDER BY sal; SELECT ename FROM emp WHERE deptno=10 ORDER BY sal
*
ERROR at line 1：
ORA01157： cannot identify/lock data file 201 see DBWR trace file
ORA01110： data file 201： ’/u01/app/oracle/oradata/orcl/temp01.dbf’
What is a possible reason？（）
A.The tempfile belonging to the default temporary tablespace is missing.
B.The database is opened in restricted mode， so queries are not allowed.
C.The default temporary tablespace required to execute the query is offline.
D.The default temporary tablespace required to execute the query is dropped.
E.The default temporary tablespace required to execute the query is readonly.
A.The database opens normally.
B.The database prompts for a database recovery.
C.The database writer writes to a trace file， indicating that the temporary file is not found.
D.The database gets mounted and throws an error indicating that the temporary file requires recovery.
A.It would result in an error because the warning threshold cannot be more than the critical threshold.
B.The warning threshold is ignored and alerts would be generated when space usage exceeds the critical threshold.
C.The critical threshold is ignored and alerts would be generated when space usage exceeds the warning threshold.
D.Both threshold values are used and alerts are generated when space usage exceeds the respective threshold values.
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

Your database operates in ARCHIVELOG mode. Usermanaged consistent backups are performed every Sunday night. On Tuesday， client A drops a table at 8：00 a.m. as follows： SQL> DROP TABLE cust_ord PURGE; Table dropped. Client B executes a query at 9：00 a.m. on the same table as follows： SQL> SELECT * FROM cust_ord;SELECT * FROM cust_ord* ERROR at line 1： ORA00942： table or view does not exist Client B needs the dropped table and reports the problem to you. With reference to this scenario， which action should you take？（）
The current time is 12：00 noon. You want to recover the USERS tablespace from a failure that occurred at 11：50 a.m. You discover that the only member of an unarchived redo log group containing information from 11：40 a.m. onwards is corrupt. With reference to this scenario， if you are not using Recovery Manager （RMAN）， which recovery method would you use？（）
Your database operates in ARCHIVELOG mode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence， 230， is not archived， and it contained information from 10：35 a.m. onwards. The current time is 11：00 a.m. Because of a disk crash， you executed the following command to perform an incomplete recovery： RMAN> RUN { 2> SET UNTIL SEQUENCE 230 THREAD 1; 3> ALTER DATABASE MOUNT; 4> RESTORE DATABASE; 5> RECOVER DATABASE; 6> ALTER DATABASE OPEN RESETLOGS;7> }; With reference to this scenario， which statement is true？（）
You decided to change the location of the flash recovery area. You executed the following command： Which statement is true？（）
You are using Oracle Database 10g. The LOG_ARCHIVE_FORMAT parameter is set to ’LOG%t_%s_%r.dbf’. Why is %r used in the file name format？（）
You performed an incomplete recovery on your Oracle Database 10g database using the following command： SQL> RECOVER DATABASE 2 UNTIL TIME ’20040805：12：10：03’ 3 USING BACKUP CONTROLFILE; In which situation would the above recovery be required？（）
View the Exhibit. One of the important tables in the USERS tablespace was dropped and purged from the recycle bin at 9：00 a.m. You noticed this at 11：00 a.m. and you want to perform an incomplete recovery to recover the table. Which statement is true？（）
View the Exhibit and examine the Flashback Database architecture. Identify the missing component （shown with a "？"） in the Flashback Database architecture.（）
You are working on Oracle Database 10g， which is in ARCHIVELOG mode. All the archived log files are intact. In which scenario would performing a recovery require the opening of the database with the RESETLOGS option？（）
You lost the PRODSTD tablespace， which was read/write. The tablespace was readonly when the last backup was performed. How would you recover the tablespace？（）
