B.restore the full database to recover the data up to the point when you performed the backup
C.restore the tablespace from the backup, and then perform a recovery using the backup control file

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

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?()
You have a readonly tablespace on readonly media. You want to perform a media recovery on the existing data files, but using a backup control file. The backup control file indicates that the status of the readonly tablespace was read/write when the control file was backed up. What should you consider?()
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?()
You lost the index tablespace in your database. You are not able to use tablespace pointintime recovery on the index tablespace. What could be the reason for this?()
You are connected to Recovery Manager (RMAN) without a recovery catalog. There is no copy of the control file available. You want to restore the control file from an autobackup. To retrieve the autobackup,you need the database ID (DBID). In which two sources would you find the DBID? ()
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?()
In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog. The following commands are used in the process of recovering the database by using the backup control file: In what sequence would you use this process to perform the recovery?()
In which case would you use the Flashback Database feature to perform a recovery?()
You performed a backup of the flash recovery area by using the following command for the first time:RMAN> BACKUP RECOVERY AREA; Which files in the flash recovery area are backed up?()
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?()
