Exam A

QUESTION 1View the Exhibit and examine the parameter settings in your server-side parameter file (SPFILE). When you tried to start the database instance, you received thefollowing error:

SQL> startup

ORA-00824: cannot set SGA_TARGET or MEMORY_TARGET due to existing internal settings, see alert log for more information

Why did the instance fail to start?

Exhibit:

A. Because the PGA_AGGREGATE_TARGET parameter is not setB. Because the STATISTICS_LEVEL parameter is set to BASICC. Because MEMORY_TARGET and MEMORY_MAX_TARGET cannot be equalD. Because both the SGA_TARGET and MEMORY_TARGET parameters are set.

Correct Answer: BSection: (none)Explanation

Explanation/Reference:Explanation:Setting SGA Target SizeYou enable the automatic shared memory management feature by setting the SGA_TARGET parameter to an on zero value. This parameter sets the total size ofthe SGA. It replaces theparameters that control the memory allocated for a specific set of individual components, which are now automatically and dynamically resized (tuned) as needed.Note:The STATISTICS_LEVEL initialization parameter must be set to TYPICAL (the default) or ALL for automatic shared memory management to function.

QUESTION 2Which two statements are true regarding an Automatic Storage Management (ASM) instance? (Choose two.)

A. An ASM instance mounts an ASM control fileB. An ASM instance uses the ASMB process for rebalancing of disks within a disk groupC. Automatic Memory Management is enabled in an ASM instance even when the MEMORY_TARGET parameters not set explicitlyD. An RDBMS instance gets connected to an ASM instance using ASMB as a foreground process when the database instance is started

Correct Answer: CDSection: (none)Explanation

Explanation/Reference:

QUESTION 3You are using the flash recovery area (fast recovery area in 11g Release 2) to store backup related files in your database. After regular monitoring of space usagein the Mash recovery area. You realize that the flash recovery area is (jetting filled up very fast and it is running out of space. Your database flash recovery area islow on specie and you have no more room on disk.

Proactively, which two options could you use to make more space available in the flash recovery [Choose two]

A. Change the RMAN archived log deletion policy.B. Use the RMAN CROSSCHECK command to reclaim the archived log space.C. Change the RMAN retention policy to retain backups for a shorter period of time.D. Use OS command to move files from the flash recovery area to some other location

Correct Answer: BDSection: (none)Explanation

Explanation/Reference:answer is verified.

QUESTION 4Which two commands never trigger an implicit rebalancing within the disk group?. (Choose two.)


A. ALTER DISKGROUP misc MOUNT;B. ALTER DISKGROUP misc DROP DISK misc2;C. ALTER DISKGROUP misc CHECK ALL NOREPAIR;D. ALTER DISKGROUP misc RESIZE ALL SIZE 1023m;E. ALTER DISKGROUP dgroupA ADD DISK '/devices/A*';

Correct Answer: ACSection: (none)Explanation

Explanation/Reference:Altering Disk GroupsYou can use the ALTER DISKGROUP SQL statement to alter a disk group configuration. You can add, resize, or drop disks while the database remains online.Whenever possible, multiple operations in a single ALTERDISKGROUP statement are recommended. Grouping operations in a single ALTER DISKGROUPstatement can reduce rebalancing operations. Oracle ASM automatically rebalances when the configuration of a disk group changes. By default, the ALTER

DISKGROUP statement does not wait until the operation is complete before returning. Query theV$ASM_OPERATION view to monitor the status of this operation.add_disk_clauseUse this clause to add one or more disks to the disk group and specify attributes for the newly added disk. Oracle ASM automatically rebalances the disk group aspart of this operation.drop_disk_clauseUse this clause to drop one or more disks from the disk group.DROP DISKThe DROP DISK clause lets you drop one or more disks from the disk group and automatically rebalance the disk group. When you drop a disk, Oracle ASMrelocates all the data from the disk and clears the disk header so that it no longer is part of the disk group. The disk header is not cleared if you specify the FORCEkeyword.

QUESTION 5Before a Flashback Table operation, you execute the following command:

ALTER TABLE employees ENABLE ROW MOVEMENT;Why would you need this to be executed?

A. Because row IDs may change during the flashback operationB. Because the object number changes after the flashback operationC. Because the rows are retrieved from the recycle bin during the flashback operationD. Because the table is moved forward and back to a temporary during the flashback opertion

Correct Answer: ASection: (none)Explanation

Explanation/Reference:Explanation:

QUESTION 6Examine the following set of RMAN commands:

RMAN> CONFIGURE CHANNELdelDEVICETYPEDISK FORMAT '/u02/backup/%U*;

RKAN>RUN

{

ALLOCATECHANNELchlDEVICETYPEDISK;

EXECUTESCRIPTfull_backup;

}

Which statement is true when the RMAN run block is executed?

A. The execution of the script fails because multiple channels cannot coexist.B. The script is executed and both the channels are used for the script execution.C. The new channel, CH1, is ignored because a channel has been configured already.D. The persistent configuration parameter DC1 is overridden because a new channel is allocated in the RMAN run block.

Correct Answer: DSection: (none)Explanation


QUESTION 7Your database is using a default temporary tablespace that contains the temp01.tmp temporary file. All the users on the database use the default temporarytablespace. A user issues a query onthe orders table and receives the following error:

ERROR at line I:

ORA-0I565: error in identifying file '/u01/app/oracle/oradata/TEST/temp01.tmp'

ORA-27037: unable to obtain file status

What would be the most efficient way to rectify this error?

A. Add a new tempfile to the user's temporary tablespace and drop the tempfile that produced the error.B. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.C. Allow the database to continue running, drop the temp01.tmp temporary file, and then re-create it with new tempfiles.D. Take the temporary tablespace offline, recover the missing tempfile by applying redo logs, and then bring the temporary tablespace online.

Correct Answer: BCDSection: (none)Explanation


QUESTION 17Your database is open and running in ARCHIVELOG mode.

You take RMAN full backups every Sunday night.On Monday morning, while querying the user1.emoloyees table, you receive the following error message:

01578: ORACLE data block corrupted (file # 5, block # 51) ORA-0lll0: data file 5:

'/u01/app/oracle/oradata/orcl/exanple0l.dbf*

You need to recover from this while ensuring that:

1. The data file remains online.

2. Mean Time To Recover (MTTR) is minimized as much as possible

You have no backup control file, but all the archived logs are accessible. Which method will best satisfy the requirements?

A. flash back the corrupted blocksB. use the DBMS_REPAIR packageC. use RMAN tablespace point in time recoveryD. use the RMAN BLCCKRECOVER commandE. perform a table point in time recovery with datapump export and import



QUESTION 18You execute the following command to set the redundancy retention policy in Recovery Manager (RMAN):

RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;

Identify the statement that correctly describes the implications of this command.

A. when there are already three backups, for the fourth backup RMAN removes the oldest backup.B. When there are already three backups, for the fourth backup RMAN marks the oldest backup as obsolete.C. the number of backups that are retained is equal to three and it includes full, incremental, and cumulativebackups.D. when there are already three backup, one of the existing backups must be removed manually before takingthe fourth backup.


Explanation/Reference:Configuring a Redundancy-Based Retention PolicyThe REDUNDANCY parameter of the CONFIGURE RETENTION POLICY command specifies how many full or level 0 backups of each data file and control filethat RMAN should keep. If the number of full or level 0backups for a specific data file or control file exceeds the REDUNDANCY setting, then RMAN considers theextra backups as obsolete. The default retention policy is REDUNDANCY 1.As you produce more backups, RMAN keeps track of which ones to retain and which are obsolete. RMAN retains all archived logs and incremental backups thatare needed to recover the non obsolete backups.Assume that you make a full backup of data file 7 on Monday, Tuesday, Wednesday, and Thursday. You now have four full backups of this data file. IfREDUNDANCY is 2, then the Monday and Tuesday backups are obsolete. If you make another backup on Friday, then the Wednesday backup of data file 7becomes obsolete. Assume a different case in which REDUNDANCY is 1. You run a level 0 database backup at noon on Monday, a level 1 cumulative backup atnoon on Tuesday and Wednesday, and a level 0 backup at noon on Thursday. Immediately after each daily backup you run the command DELETE OBSOLETE.The Wednesday DELETE command does not remove the Tuesday level 1 backup because this backup is not redundant: the Tuesday level 1 backup could be usedto recover the Monday level 0 backup to a time between noon on Tuesday and noon on Wednesday. However, the DELETE command on Thursday removes theprevious level 0 and level 1backups. Run the CONFIGURE RETENTION POLICY command at the RMAN prompt, as in the following example: CONFIGURERETENTION POLICY TO REDUNDANCY 3;

QUESTION 19Examine the following ALTER command:

SQL> ALTER DISKGROUP dgroup1 UNDROP DISKS;

What is the purpose of the command?

A. It cancels all pending disk drops within the disk group.B. It adds previously dropped disks back into the disk group.C. It restores disks that are being dropped as the result of a DROP DISKGROUP operation.D. It mounts disks in the disk group for which the drop-disk operation has already been completed.E. It restores all the dropped disks in the disk group for which the drop-disk operation has already been completed.



QUESTION 20You perform an RMAN block media recovery on the tools 01.dbf data file in the SALES database.

Which two statements are true?

A. You must ensure that the SALES database is mounted or open.B. You must restore a backup control file to perform a block media recovery.C. You must take the tools01.dbf data file offline before you start a block media recovery.D. You must put the database in NOARCHIVELOG mode to perform a block media recovery.E. You can perform only a complete media recovery of individual blocks, point-in-time recovery of individualdata blocks is not supported.

Correct Answer: AESection: (none)Explanation


QUESTION 21Which statement is true regarding the creation of nested plans using the Oracle Resource Manager?

A. Only one nested subplan is allowed per parent planB. The plans can be nested up to four levels.C. Nested plans only control resources used by recursive SQLD. Nested plans control only the degree of parallelism and I/O requestsE. Each nested plan gets a proportion of the CPU resources assigned to its parent group.

Correct Answer: ESection: (none)Explanation


QUESTION 22There was media failure and you decide to check the data files for block corruption. Which would you use to create a report on any corruptions found?

A. the DBNEWID utilityB. the DBVERIFY utilityC. the ANALYZE commandD. the RMAN REPORT commandE. the RMAN CROSSCHECK commandF. the CHECK_OBJECT procedure of the DBMS_REPAIR package



QUESTION 23You are in the middle of a transaction updating a very important table. The machine on which a database was running reboots because of power outage. Thiscaused a database instance failure.

Which statement is true in this situation?

A. The online redo log files and archived redo log files are required to accomplish the recoveryB. The uncommitted transaction will be committed at the next startup of the database instanceC. The uncommitted transaction is rolled back automatically at the next opening of the databaseD. The DBA has to perform the recovery on the database to recover the uncommitted transaction



QUESTION 24You executed the following command In Recovery Manager {RMAN):

RMAN>REPORTNEEDBACKUPdays 3;

What is the output of this command?

A. a list of files that require a backup within three daysB. a list of files requiring more than 3 days of archive logs to applyC. a list of files that RMAN recommends be backed up only once in every three days, based on low volatilityD. a list of files for which a backup has already been performed in the last three days and which is required tobe backed up again based on the high number of

transactions performed on them

Correct Answer: B

Section: (none)Explanation

Explanation/Reference:Using RMAN REPORT NEED BACKUP with Different Retention Policies (link) You can specify different criteria for REPORT NEED BACKUP, using one of thefollowing forms of the command:

REPORT NEED BACKUP RECOVERY WINDOW OF n DAYSDisplays objects requiring backup to satisfy a recovery window-based retention policy REPORT NEED BACKUP REDUNDANCY nDisplays objects requiring backup to satisfy a redundancy-based retention policy REPORT NEED BACKUP DAYS nDisplays files that require more than n days' worth of archived redo log files for recovery REPORT NEED BACKUP INCREMENTAL nDisplays files that require application of more than n incremental backups for recovery

QUESTION 25Examine the parameter settings in your database.

Which statement is correct about the database?

A. Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not set.B. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are set.C. The database is opened but users cannot perform transactions until Real 27

Oracle 1z0-034 ExamPGA_AGGREGATE_TARGET andSGA_TARGET are set.

D. Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program GlobalArea (PGA) will be distributed at startup


Explanation/Reference:Explanation:http://download.oracle.com/docs/cd/B14117_01/server.101/b10752/memory.htm#47750

Configuring Automatic PGA MemoryWhen configuring a brand new instance, it is hard to know precisely the appropriate setting for PGA_AGGREGATE_TARGET. You can determine this setting inthree stages:

Make a first estimate for PGA_AGGREGATE_TARGET, based on a rule of thumb. By default, Oracle uses 20% of the SGA size. However, this initial setting maybe too low for a large DSS system.

Run a representative workload on the instance and monitor performance, using PGA statistics collected by Oracle, to see whether the maximum PGA size is under-configured or over- configured.

Tune PGA_AGGREGATE_TARGET, using Oracle PGA advice statistics.

Which statement is correct about the database?

A. Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not set.B. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET andC. SGA_TARGET are set.D. The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are set.E. Automatic memory management is enabled and, as per the policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program

Global Area (PGA) will be distributed at startup.



QUESTION 27The DB_BLOCK_CHECKING parameter is set to FALSE.

What level of block checking will be performed?

A. The Oracle database will not perform block checking for any of the data blocks.B. The Oracle database will perform block checking for the default permanent tablespace only.C. The Oracle database will perform block checking for the data blocks in all user tablespaces.D. The Oracle database will perform block checking for the data blocks in the SYSTEM tablespace only.E. The Oracle database will perform block checking for the data blocks in the SYSTEM and SYSAUX tablespaces.



QUESTION 28

As part of archiving the historical data, you want to transfer data from one database to another database, whichis on another server. All tablespaces in the sourcedatabase are read/write and online. The source and targetdatabases use the same compatibility level and character sets. View the Exhibit and examine the featuresinthe source and target database.

Which of the following steps are required to transport a tablespace from the database to the targetdatabase:

1. Make the tablespace read-only at the source database.

2. Export metadata from the source database.

3. Convert data filed by using Recovery Manager (RMAN).

4. Transfer the dump file and data filed to the target machine.

5. Import metadata at the target database.

6. Make the tablespace read/write at the target database.

Exhibit:

A. 2, 4, and 5B. All the stepsC. 2, 3, 4 and 5D. 1, 2, 4, 5 and 6


Explanation/Reference:Explanation:Refer to here. Generate a Transportable Tablespace Set

read_only--expdp--4-import-read_wrtie

1, 2, 4, 5, 6 (optional)

If both platforms have the same endianness, no conversion is necessary. Otherwise you must do aconversion of the tablespace set either at the source ordestination database. Transport the dump file to the directory pointed to by the DATA_PUMP_DIR directory object, or to any otherdirectory of your choosing.

Run the following query to determine the location of DATA_PUMP_DIR:SELECT * FROM DBA_DIRECTORIES WHERE DIRECTORY_NAME = 'DATA_PUMP_DIR';

Transport the data files to the location of the existing data files of the destination database. On the UNIX and Linux platforms, this location is typically /u01/app/oracle/oradata/SID/ or +DISKGROUP/SID/datafile/.

QUESTION 29You are in the process of creating a virtual private catalog in your Oracle Database 11g database. The PROD1,PROD2, and PROD3 Oracle Database 10gdatabases are registered in the base recovery catalog. The databaseuser who owns the base recovery catalog is CATOWNER. CATOWNER executes thefollowing command to grantprivileges to a new user VPC1 using Oracle Database 11g RMAN executables:

RMAN> GRANT CATALOG FOR DATABASE prod1, prod2 TO vpc1;

Then you issue the following commands:

RMAN> CONNECT CATALOG vpc1/oracle@catdb;

RMAN> SQL "EXEC catowner.dbms_rcvcat.create_virtual_catalog;"

What is the outcome of the above commands?

A. They execute and create a virtual catalog for pre-Oracle 11g clients.B. They produce an error because PROD1 and PROD2 databases belong to the older version.C. They produce an error because you need to connect as CATOWNER to execute this packaged procedure.D. They produce an error because you need to connect to the target database to execute this packagedprocedure.

Correct Answer: A


Explanation/Reference:answer is corrected.

QUESTION 30Examine the following command for RMAN backup:

RMAN> RUN {

ALLOCATE CHANNEL c1 DEVICE TYPE sbt;



BACKUP

INCREMENTAL LEVEL = 0

(DATAFILE 1,4,5 CHANNEL c1)


(DATAFILE 6,7,8 CHANNEL c3);

SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';

}

Which statement is true regarding the approach in the command?

A. The RMAN multiplexing level is 4.B. It is the use of asynchronous I/O by RMAN.C. It is a case of parallelization of the backup set.D. It is an implementation of a multi section backup.



QUESTION 31Which two statements are true about the duplexing of the backups taken by RMAN? (Choose two.)

A. It's only supported for the backups performed on the tapeB. It is not supported for backup operations that produce image copiesC. Duplex backups need a parallelism for the device to be equal to number of copiesD. Duplex backups can be performed to either disk or tape, but cannot be performed on tape and disk simultaneously



QUESTION 32To enable faster incremental backups, you enabled block change tracking for the database. Which two statements are true about the block change tracking file?(Choose two.)

A. Multiple change tracking files can be created for a database.B. The change tracking file must be created after the first level 0 backup.C. RMAN does not support backup and recovery of the change tracking file.D. The database clears the change tracking file and starts tracking changes again, after whole database restore and recovery operations.



QUESTION 33For which two database objects can the VERSIONS clause of the Flashback Versions Query be used?

A. fixed tables

B. heap tablesC. external tablesD. temporary tablesE. Index-Organized Tables (IOTs)F. views

Correct Answer: BESection: (none)Explanation


QUESTION 34The BACKUP_TAPE_IO_SLAVES parameter is set to FALSE for the database instance.

Which statement is true while performing a tape backup in an RMAN session?

A. The tape I/O performed is asynchronousB. The tape buffer is allocated from the System Global Area (SGA)C. The tape buffer is allocated from the Program Global Area (PGA)D. Oracle I/O uses an interrupt mechanism to determine when each I/O completes


Explanation/Reference:Explanation:Tape I/O SlavesRMAN allocates the tape buffers in the System Global Area (SGA) or the Program Global Area (PGA),depending on whether I/O slaves are used. If you set theinitialization parameter BACKUP_TAPE_IO_SLAVES=true, then RMAN allocates tape buffers from the SGA. Tape devices can only beaccessed by one process ata time, so RMAN starts as many slaves as necessary for the number of tapedevices. If the LARGE_POOL_SIZE initialization parameter is also set, then RMANallocates buffers from thelarge pool. If you set BACKUP_TAPE_IO_SLAVES=false, then RMAN allocates the buffers from the PGA. If you use I/O slaves, then setthe LARGE_POOL_SIZE initialization parameter to dedicate SGA memory toholding these large memory allocations. This parameter prevents RMAN I/O buffersfrom competing with thelibrary cache for SGA memory. If I/O slaves for tape I/O were requested but there is not enough space in theSGA for them, slaves are notused, and a message appears in the alert log.The parameter BACKUP_TAPE_IO_SLAVES specifies whether RMAN uses slave processes rather than thenumber of slave processes. Tape devices can only beaccessed by one process at a time, and RMAN uses thenumber of slaves necessary for the number of tape devices.

QUESTION 35What does the DB_FLASHBACK_RETENTION_TARGET parameter configure?

A. An upper limit on how far you can flash back the database, depending on the information in the redo logsB. An upper limit on how far you can flash back the database, depending on the information in the undo tablespaceC. The amount of time for which the flashback data is to be kept in the flash recovery area, provided that there is enough spaceD. The amount of time for which the flashback data is guaranteed to be kept in the undo tablespace, provide that there is enough space



QUESTION 36You want to perform an RMAN backup of database as a copy. Which two factors will you consider while performing the backup operation?

A. The backup as copy can only be taken to diskB. The backup as copy can only be taken to tapeC. Backup can be performed only when the instance is shutdownD. Backup will constitute all used and unused blocks in the database

Correct Answer: ADSection: (none)Explanation


QUESTION 37You executed the following commands:

SQL> ALTER SESSION SET OPTIMIZER_USE_PENDING_STATISTICS = false;

SQL> EXECUTE DBMS_STATS. SET_TABLE_PREFS('SH', 'CUSTOMERS', 'PUBLISH', 'false');

SQL> EXECUTE DBMS_STATS. GATHER_TABLE_STATS ('SH' , 'CUSTOMERS');

Which statement is correct regarding the above statistics collection on the SH.CUSTOMERS table in the above session?

A. The statistics are stored in the pending statistics table in the data dictionary.B. The statistics are treated as the current statistics by the optimizer for all sessions.C. The statistics are treated as the current statistics by the optimizer for the current sessions only.D. The statistics are temporary and used by the optimizer for all sessions until this session terminates.



QUESTION 38Which two statements are true about encrypting RMAN backups?

A. The transparent encryption of backups uses the encryption wallet.B. The database uses the same encryption key for every encrypted backup.C. The password encryption of backups only uses the password while creating and restoring backups.D. If transparent encryption is configured, you cannot use the set encryption by password command to make password-protected backups.



QUESTION 39You work with a newly created database. Presently, there is no application load on the database instance. You want to create a baseline for tuning the application,so you decide to collect recommendations that can be implemented to improve application performance.

What action must you take to achieve this?

A. Run Segment Advisor.B. Run the SQL Tuning Advisor (STA).C. Run the Automatic Workload Repository (AWR) report.D. Run the SQL Access Advisor with a hypothetical workload.



QUESTION 40Because of a logical corruption in your production database, you wanted to perform Tablespace Point in TimeRecovery (TSPITR). But before you start the recovery,you queried the TS_PITR_OBJECTS_TO_BE_DROPPEDview and realized that there are a large number of objects that would be dropped when you start therecoveryby using this method. You want to preserve these objects. Which option must you use to perform TSPITR andpreserve the object?

A. Perform Export before TSPITR and Import after TSPITRB. Move objects to another schema that has the same tablespace assignedC. Perform Incomplete Recovery before TSPITR with the Log Sequence Number (LSN)D. Perform Incomplete Recovery before TSPITR with the System Change Number (SCN)



QUESTION 41View the following SQL statements:

Transaction T1

SQL> INSERT INTO hr.regions

2 VALUES (5,'Pole');

3 COMMIT;

Transaction T2

SQL> UPDATE hr.regions

2 SET region_name='Poles'

3 WHERE region_id = 5;

4 COMMIT;

Transaction T3

SQL> UPDATE hr.regions

2 SET region_name='North and South Poles'

3 WHERE region_id = 5;

You want to back out transaction T2. Which option would you use?

A. It is possible, but transaction T3 also backs out.B. It is possible with the NOCASCADE_FORCE option.C. It is possible with the NONCONFLICT_ONLY option.D. It is not possible because it has conflicts with transaction T3.


Explanation/Reference:Explanation:Table 12-2 Flashback TRANSACTION_BACKOUT Options

CASCADEBacks out specified transactions and all dependent transactions in a post-order fashion (that is, children arebacked out before parents are backed out). WithoutCASCADE, if any dependent transaction is not specified, an error occurs.

NOCASCADEDefault. Backs out specified transactions, which are expected to have no dependent transactions. Firstdependent transactions causes an error and appears in*_FLASHBACK_TXN_REPORT.

NOCASCADE_FORCEBacks out specified transactions, ignoring dependent transactions. Server runs undo SQL statements forspecified transactions in reverse order of commit times.Ifno constraints break and you are satisfied with the result, you can commit the changes; otherwise, you canroll them back.

NONCONFLICT_ONLYBacks out changes to nonconflicting rows of the specified transactions. Database remains consistent, buttransaction atomicity is lost.

QUESTION 57You created a database with the Database Configuration Assistant (DBCA) by using one of the default templates.

Which tablespace will be the default permanent tablespace for non-system users, excluding DBSNMP and OUTLN?

A. USERSB. SYSTEMC. SYSAUXD. EXAMPLEE. SAMPLE


Explanation/Reference:Explanation: USERSThis tablespace is used to store permanent user objects and data. Like the TEMP tablespace, every database should have a tablespace for permanent user datathat is assigned to users. Otherwise, user objects will be created in the SYSTEM tablespace, which is not good practice. In the preconfigured database, USERS isassigned the default tablespace, and space for all objects created by non-system users comes from this tablespace. For system users, the default permanenttablespace remains SYSTEM.REF.: Oracle(r) 10g 2 Days DBA, 6-7

12. FROM employees e, departments d;

Which line of the command would cause an error?

A. line 2, because the column names have been specifiedB. line 7, because file name must have a .dat extensionC. line 3, because ORGANIZATION EXTERNAL has been specifiedD. line 9, because the PARALLEL option cannot be specified with one file nameE. line 12, because there is no join defined between EMPLOYEES and DEPARTMENTS tableF. line 5, because ORACLE_LOADER is not a valid structure for external table creation with the SELECT statement

Correct Answer: FSection: (none)Explanation

Explanation/Reference:Explanation: External tables are created using the SQL CREATE TABLE...ORGANIZATION EXTERNAL statement. When you create an external table, you specifythe followingattributes:1. TYPE - specifies the type of external table. The two available types are the ORACLE_LOADER type and the ORACLE_DATAPUMP type. Each type of externaltable is supported by its own access driver.* The ORACLE_LOADER access driver is the default. It can perform only data loads, and the data must comefrom text datafiles. Loads from external tables tointernal tables are done by reading from the external tables' text-only datafiles .* The ORACLE_DATAPUMP access driver can perform both loads and unloads. The data must come from binary dump files. Loads to internal tables from externaltables are done by fetching from the binary dump files. Unloads from internal tables to external tables are done by populating the external tables' binary dump files.2. DEFAULT DIRECTORY - specifies the default location of files that are read or written by external tables. The location is specified with a directory object, not adirectory path.3. ACCESS PARAMETERS - describe the external data source and implements the type of external table that was specified. Each type of external table has its ownaccess driver that provides access parameters unique to that type of external table.4. LOCATION - specifies the location of the external data. The location is specified as a list of directory objects and filenames. If the directory object is not specified,then the default directory object is used as the file location.

QUESTION 62View the Exhibits exhibit1 and exhibit2.

Both the processes use PROG_1 as the job template that is already available. The time taken by the jobs are recorded in the TEST_LOG table. While comparingthe time taken to create the jobs, the process in exhibit1 takes less time than the process in exhibit2.

What is the reason for this?

lightweight-job-1 (exhibit):

lightweight-job-2 (exhibit):

A. It updates several tables in the SYSTEM tablespace instead of creating new tables.B. It creates jobs temporarily in memory only.C. It creates less metadata for the jobs.D. It writes the job metadata to disk in compressed format.


Explanation/Reference:Explanation:The difference between two blocks of code is the "JOB_STYLE". The lightweight job creates less

metadata for the jobs.

QUESTION 63Which two statements are correct about database transportation? (Choose two.)

A. The source and target platforms must be the sameB. Redo logs, control files and temp files are also transportedC. The transported database must have the same database identifier (DBID) as the source database and cannot be changedD. The COMPATIBLE parameter must be set to 10.0.0.0 or higher and the database must be opened in readonly mode before being transportedE.

QUESTION 72Which two statements are true regarding hot patching? (Choose two.)

A. It requires relinking of the Oracle binary.B. It does not require database instance shutdown.C. It can detect conflicts between two online patches.D. It is available for installing all patches on all platforms.E. It works only in a single database instance environment.


Explanation/Reference:Explanation:Online PatchingRegular patches typically contain .o (object) files and/or .a (archive) libraries, and therefore require a relink of the RDBMS binary. Online patches, however, contain.so files, which are dynamic/shared libraries, and do not require a relink of the RDBMS binary. Consequently, since a relink is not needed, you can apply or roll backonline patches while the RDBMS instance is running. This simplifies administration, because no downtime is needed, and also results in a much quicker turnaroundtime for installing or de-installing Online Patches.A regular RDBMS patch can require many minutes to install, since it requires instance shutdown, a relink, and instance startup. On the other hand, you can installan online patch in just a few seconds.Online patches are only applicable for Oracle RDBMS and not any other products. Online patches are currently supported on the following Windows and UNIXplatforms for version 11.2.0.1.0 and later:

About Patch Conflicts:

All patches may not be compatible with one another. For example, if you apply a patch, all the bugs the patch fixes could reappear after you apply another patch.This is called a conflict situation. OPatch detects such situations and raises an error when it detects a conflict.

QUESTION 86You are managing an Oracle Database 11g instance with ASM storage. You lost an ASM disk group DATA. You have RMAN backup of data as well as ASMmetadata backup. You want to re- create the missing disk group by using the ASMCMD md_restore command.

Which of these methods would you use to achieve this? (Choose all that apply.)

A. Restore the disk group with the exact configuration as the backed-up disk group, using the same disk group name, same set of disks, failure groupconfigurations, and data on the disk group.

B. Restore the disk group with the exact configuration as the backed-up disk group, using the same disk group name, same set of disks, and failure groupconfigurations.

C. Restore the disk group with changed disk group specification, failure group specification, disk group name, and other disk attributes.D. Restore metadata in an existing disk group by passing the existing disk group name as an input parameter.

Specifying this flag ignores any errors.--fullSpecifies to create a disk group and restore metadata.--nodgSpecifies to restore metadata only.--newdg -o old_diskgroup:new_diskgroup]Specifies to create a disk group with a different name when restoring metadata. The -o option is required with--newdg.-S sql_script_fileWrite SQL commands to the specified SQL script file instead of executing the commands.-G diskgroupSelect the disk groups to be restored. If no disk groups are defined, then all disk groups are restored.

QUESTION 87Which statement is true about a Scheduler-generated event?

A. It can be generated when a file arrives on the file system.B. it indicates state changes that occur within the Scheduler itself.C. it is raised by an application that is consumed by the Scheduler to start a job.D. it requires jobs to be defined with an event condition and a queue specification.


Explanation/Reference:Consuming Job State Events with your ApplicationTo consume job state events, your application must subscribe to the Scheduler event queue SYS.SCHEDULER$_EVENT_QUEUE. This queue is a secure queueand is owned by SYS. To create a subscription to this queue for a user, do the following:1. Log in to the database as the SYS user or as a user with the MANAGE ANY QUEUE privilege.2. Subscribe to the queue using a new or existing agent.3. Run the package procedure DBMS_AQADM.ENABLE_DB_ACCESS as follows:DBMS_AQADM.ENABLE_DB_ACCESS(agent_name, db_username); where agent_name references the agent that you used to subscribe to the events queue,and db_username is the user for whom you want to create a subscription.There is no need to grant dequeue privileges to the user. The dequeue privilege is granted on the Scheduler event queue to PUBLIC.

QUESTION 89You are using Recovery Manager (RMAN) with a recovery catalog to back up your production database. The backups and the archived redo log files are copied to atape drive on a daily basis. Because of media failure, you lost your production database completely along with the recovery catalog database. You want to recoverthe target database and make it functional. You consider performing the following steps to accomplish the task:

1. Restore an autobackup of the server parameter file.

2. Restore the control file

3. Start the target database instance

4. Mount the database

5. Restore the data files

6. Open the database with RESETLOGS option

7. Recover the data files

8. Set DBID for the target database

Which option illustrates the correct sequence that you must use?

Explanation/Reference:Explanation:Recovering the Database After a DisasterThe procedure for disaster recovery is similar to the procedure for recovering the database with a backup control file in NOCATALOG mode. If you are restoring thedatabase to a new host, then you should also review the considerations described in "Restoring a Database on a New Host". This scenario assumes that the Linuxserver on which your database was running has been damaged beyond repair. Fortunately, you backed up the database to Oracle Secure Backup and have thetapes available. The scenario assumes the following:

To recover the database on the new host:1. If possible, restore or re-create all relevant network files such as tnsnames.ora and listener.ora and a password file.2. Start RMAN and connect to the target database instance. At this stage, no initialization parameter file exists. If you have set ORACLE_SID and ORACLE_HOME,then you can use operating system authentication to connect as SYSDBA. For example, start RMAN as follows:

% rmanRMAN> CONNECT TARGET/

3. Specify the DBID for the target database with the SET DBID command, as described in "Restoring the Server Parameter File".For example, enter the following command:SET DBID 676549873;4. Run the STARTUP NOMOUNT command.When the server parameter file is not available, RMAN attempts to start the instance with a dummy server parameter file.5. Allocate a channel to the media manager and then restore the server parameter file from autobackup.For example, enter the following command to restore the server parameter file from Oracle Secure Backup:

RUN{ALLOCATE CHANNEL c1 DEVICE TYPE sbt;RESTORE SPFILE FROM AUTOBACKUP;}

6. Restart the instance with the restored server parameter file.STARTUP FORCE NOMOUNT;7. Write a command file to perform the restore and recovery operation, and then execute the command file.The command file should do the following:a. Allocate a channel to the media manager.b. Restore a control file autobackup (see "Performing Recovery with a Backup Control File and No Recovery Catalog").c. Mount the restored control file.d. Catalog any backups not recorded in the repository with the CATALOG command. e. Restore the data files to their original locations. If volume names havechanged, then run SET NEWNAME commands before the restore operation and perform a switch after the restore operation to update the control file with the newlocations for the data files, as shown in the following example.f. Recover the data files. RMAN stops recovery when it reaches the log sequence number specified.

RMAN> RUN{# Manually allocate a channel to the media managerALLOCATE CHANNEL t1 DEVICE TYPE sbt;# Restore autobackup of the control file. This example assumes that you have

# accepted the default format for the autobackup name.RESTORE CONTROLFILE FROM AUTOBACKUP;# The set until command is used in case the database# structure has changed in the most recent backups, and you want to # recover to that point in time. In this way RMAN restores the database # to the samestructure that the database had at the specified time.ALTER DATABASE MOUNT;SET UNTIL SEQUENCE 1124 THREAD 1;RESTORE DATABASE;RECOVER DATABASE;}

The following example of the RUN command shows the same scenario except with new file names for the restored data files:

RMAN> RUN{# If you must restore the files to new locations,# use SET NEWNAME commands:SET NEWNAME FOR DATAFILE 1 TO '/dev/vgd_1_0/rlvt5_500M_1'; SET NEWNAME FOR DATAFILE 2 TO '/dev/vgd_1_0/rlvt5_500M_2'; SET NEWNAME FORDATAFILE 3 TO '/dev/vgd_1_0/rlvt5_500M_3'; ALLOCATE CHANNEL t1 DEVICE TYPE sbt;RESTORE CONTROLFILE FROM AUTOBACKUP;ALTER DATABASE MOUNT;SET UNTIL SEQUENCE 124 THREAD 1;

RESTORE DATABASE;SWITCH DATAFILE ALL; # Update control file with new location of data files.RECOVER DATABASE;}

8. If recovery was successful, then open the database and reset the online logs:ALTER DATABASE OPEN RESETLOGS;

QUESTION 90Which three tasks can be performed using a duplicate database? (Choose three.)

QUESTION 105Which two statements are true about a duplicate database that is created by using the DUPLICATE command in RMAN? (Choose two.)

A. It is a copy or a subset of the target database.B. It is opened in RESTRICT mode after a duplicating operation.C. It is created by using backups and archived redo log files from the target database.D. It is created with the same database identifier (DBID) as that of target database.


Explanation/Reference:Explanation:Duplicating a DatabaseOverview of RMAN Database Duplication

Database duplication is the use of the DUPLICATE command to copy all or a subset of the data in a source database. The duplicate database (the copieddatabase) functions entirely independently from the source database (the database being copied).Purpose of Database DuplicationIf you copy a database with operating system utilities instead of the DUPLICATE command, then the DBID of the copied database remains the same as the originaldatabase. To register the copy database in the same recovery catalog with the original, you must change the DBID with the DBNEWID utility (see Oracle DatabaseUtilities). In contrast, the DUPLICATE command automatically assigns the duplicate database a different DBID so that it can be registered in the same recoverycatalog as the source database.Backup-Based DuplicationIn backup-based duplication, RMAN creates the duplicate database by using pre-existing RMAN backups and copies. This technique of duplication uses one of thefollowing mutually exclusive subtechniques: Duplication without a target database connection, RMAN obtains metadata about backups from a recovery catalog.Duplication without a target database connection and without a recovery catalog. RMAN obtains metadata about where backups and copies reside from BACKUPLOCATION. Duplication with a target database connection. RMAN obtains metadata about backups from the target database control file or from the recoverycatalog.How RMAN Duplicates a DatabaseFor backup-based duplication, the principal work of the duplication is performed by the auxiliary channels. These channels correspond to a server session on theauxiliary instance on the destination host. For active database duplication the primary work is performed by target channels. RMAN must perform database point-in-time recovery, even when no explicit point in time is provided for duplication. Point-in-time recovery is required because the online redo log files in the sourcedatabase are not backed up and cannot be applied to the duplicate database. The farthest point of recovery of the duplicate database is the most recent redo logfile archived by the source database.As part of the duplicating operation, RMAN automates the following steps:

1. Creates a default server parameter file for the auxiliary instance if the following conditions are true:

2. Restores from backup or copies from active database the latest control file that satisfies the UNTIL clause requirements.3. Mounts the restored or copied backup control file from the active database.4. Uses the RMAN repository to select the backups for restoring the data files to the auxiliary instance. This step applies to backup-based duplication.5. Restores and copies the duplicate data files and recovers them with incremental backups and archived redo log files to a noncurrent point in time.6. Shuts down and restarts the database instance in NOMOUNT mode.7. Creates a new control file, which then creates and stores the new DBID in the data files.8. Opens the duplicate database with the RESETLOGS option and creates the online redo log for the new database.

QUESTION 106View Exhibit1 to examine the CRS11G disk group when all the disks are online.

View Exhibit2 to examine the CRS11G disk group when one disk is offline.

Why is the rebalancing not performed and the content of the disk group not empty in Exhibit2?

ASM-disk-group-1 (exhibit):

ASM-disk-group-2 (exhibit):

A. Because the disk group is created with NORMAL redundancyB. Because the disk repair time attribute is set to a nonzero valueC. Because the mirrored extents cannot be rebalanced across the other three disksD. Because the other three disks have 60% free space, the disk rebalancing is delayed


Explanation/Reference:Explanation:Key points:1. The COMPATIBILITY.ASM>=11.1 and COMPATIBILITY.RDBMS>=11.12. The DISK_REPAIR_TIME is set to non-zero. by default it is 3.6hr.Refer to here.Note: To use this feature, the disk group compatibility attributes must be set to 11.1 or higher. For more information, refer to "Disk Group Compatibility".

Oracle ASM fast resync keeps track of pending changes to extents on an OFFLINE disk during an outage. The extents are resynced when the disk is brought backonline. By default, Oracle ASM drops a disk in 3.6 hours after it is taken offline. You can set the DISK_REPAIR_TIME disk group attribute to delay the dropoperation by specifying a time interval to repair the disk and bring it back online.

QUESTION 107Which two statements about Oracle Direct Network File System (NFS) are true? (Choose two.)

A. It bypasses the OS file system cache.B. A separate NFS interface is required for use across Linux, UNIX, and Windows platforms.C. It uses the operating system kernel NFS layer for user tasks and network communication modules.D. File systems need not be mounted by the kernel NFS system when being served through Direct NFS.E. Oracle Disk Manager can manage NFS on its own, without using the operating system kernel NFS driver.

Correct Answer: AESection: (none)Explanation

Explanation/Reference:Explanation:Direct NFS provides faster performance that what can be provided by the operating system's NFS driver as Oracle bypasses the operating system and generatesexactly the requests it needs (no user configuration or tuning required). Data is cached just once in user space, which saves memory (no second copy in kernelspace). Performance is further improved by load balancing across multiple network interfaces (if available).

QUESTION 108Identify two options that Oracle recommends while configuring the backup and recovery environment for your recovery catalog. (Choose two.)

A. configuring control file autobackup to be ONB. backing up data filed only and not the archived redo log files

C. running the recovery catalog database in NOARCHIVELOG mode.D. setting the retention policy to a REDUNDANCY value greater than 1E. backing up the recovery catalog to the same disk as that of the target database


Explanation/Reference:Refer to here.Configuring the Recovery Catalog DatabaseWhen you use a recovery catalog, RMAN requires that you maintain a recovery catalog schema. The recovery catalog is stored in the default tablespace of theschema. The SYS user cannot be the owner of the recovery catalog.Decide which database you will use to install the recovery catalog schema, and also how you will back up this database. Also, decide whether to operate the catalogdatabase in ARCHIVELOG mode, which is recommended.Note: Do not use the target database to be backed up as the database for the recovery catalog. The recovery catalog must be protected if the target database islost.

QUESTION 109UNDO__RETENTION is set to 1000 and retention is not guaranteed.

You configure the database with a fixed size undo tablespace.

Which is true about undo retention in this configuration?

A. Undo expires after 1000 seconds and is deleted.B. Inactive undo is retained for 1000 seconds even if new transactions fail due to lack of space in the undo tablespace.C. Inactive undo is retained for at least 1000 seconds if free undo space is available.D. Undo is retained in the UNDO tablespace for 1000 seconds, and then moved to the SYSAUX tablespace to provide read consistency.

QUESTION 114You are managing an Oracle Database 11g ASM instance with a disk group dg01 having three disks.

One of the disks in the disk group becomes unavailable because of power failure. You issued the following command to change the DISK_REPAIR_TIME attributefrom 3.6 hours to 5 hours:

ALTER DISKGROUP dg01 SET ATTRIBUTE *disk_repair_time' = '5h';

To which disks in the disk group will the new value be applicable?

A. all disks in the disk groupB. all disks that are currently in OFFLINE modeC. all disks that are not currently in OFFLINE modeD. all disks in the disk group only if all of them are ONLINE


Explanation/Reference:Explanation:Check out the answer options, it is tricky. The NOT OFFLINE disks equals ONLINE disks. Refer to Set the DISK_REPAIR_TIME Disk Group AttributeAppropriately. The DISK_REPAIR_TIME disk group attribute specifies how long a disk remains offline before Oracle ASM drops the disk. If a disk is made availablebefore the DISK_REPAIR_TIME parameter has expired, the storage administrator can issue the ONLINE DISK command and Oracle ASM resynchronizes the staledata from the mirror side. In Oracle Database 11g, the online disk operation does not restart if there is a failure of the instance on which the disk is running. Youmust reissue the command manually to bring the disk online.

QUESTION 119Your production database is functional on the SHOST1 host. You are backing up the production database by using Recovery Manager (RMAN) with the recoverycatalog. You want to replicate the production database to anther host, SHOST2, for testing new applications.

After you ensured that the backups of the target database are accessible on the new host, what must you do to restore and recover the backup for the testenvironment?

A. Restoring the control file from the backup by using the NOCATALOG option to restore, and recovering the data filesB. Restoring the data files by using the NOCATALOG option and using the SET NEWNAME command to change the locationC. Restoring the server parameter file from the backup by using the recovery catalog to restore,D. Restoring the data files from the backup by using the recovery catalog to recover the files, and using the SWITCH command to change the location.


Explanation/Reference:Explanation:Refer to here:To restore the database on a new host:1. Ensure that the backups of the target database are accessible on the new host.2. Configure the ORACLE_SID on hostb.3. Start RMAN on hostb and connect to the target database without connecting to the recovery catalog.For example, enter the following command:% rman NOCATALOGRMAN> CONNECT TARGET/4. Set the DBID and start the database instance without mounting the database. For example, run SET DBID to set the DBID, then run STARTUP NOMOUNT:SET DBID 1340752057;

STARTUP NOMOUNTRMAN fails to find the server parameter file, which has not yet been restored, but starts the

instance with a "dummy" file. Sample output follows:

startup failed: ORA-01078: failure in processing system parameters LRM-00109: could not open parameter file '/net/hostb/oracle/dbs/inittrgta.ora' trying to start theOracle instance without parameter files ...Oracle instance started

5. Restore and edit the server parameter file.Allocate a channel to the media manager, then restore the server parameter file as a client-side parameter file and use the SET command to indicate the location ofthe autobackup (in this example, the autobackup is in /tmp):

RUN{ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS '...';SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/tmp/%F'; RESTORE SPFILETO PFILE '?/oradata/test/inittrgta.ora'FROM AUTOBACKUP;SHUTDOWN ABORT;}

6. Edit the restored initialization parameter file.Change any location-specific parameters, for example, those ending in _DEST, to reflect the new directory structure. For example, edit the following parameters:

- IFILE- LOG_ARCHIVE_DEST_1- CONTROL_FILES

7. Restart the instance with the edited initialization parameter file.For example, enter the following command:

STARTUP FORCE NOMOUNT PFILE='?/oradata/test/inittrgta.ora';

8. Restore the control file from an autobackup and then mount the database.For example, enter the following command:

RUN{ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS '...';

RESTORE CONTROLFILE FROM AUTOBACKUP;ALTER DATABASE MOUNT;}

RMAN restores the control file to whatever locations you specified in the CONTROL_FILES initialization parameter.9. Catalog the data file copies that you copied in "Restoring Disk Backups to a New Host", using their new file names or CATALOG START WITH (if you know allthe files are in directories with a common prefix easily addressed with a CATALOG START WITH command). For example, run:CATALOG START WITH '/oracle/oradata/trgt/';If you want to specify files individually, then you can execute a CATALOG command as follows:

Start a SQL*Plus session on the new database and query the database file names recorded in the control file.Because the control file is from the trgta database, the recorded file names use the original hosta file names. You can query V$ views to obtain this information. Runthe following query in SQL*Plus:

COLUMN NAME FORMAT a60SPOOL LOG '/tmp/db_filenames.out'SELECT FILE# AS "File/Grp#", NAMEFROM V$DATAFILEUNIONSELECT GROUP#,MEMBERFROM V$LOGFILE;SPOOL OFFEXIT

11. Write the RMAN restore and recovery script. The script must include the following steps:a. For each data file on the destination host that is restored to a different path than it had on the source host, use a SET NEWNAME command to specify the newpath on the destination host. If the file systems on the destination system are set up to have the same paths as the source host, then do not use SET NEWNAMEfor those files restored to the same path as on the source host. b. For each online redo log that is to be created at a different location than it had on the source host,use SQL ALTER DATABASE RENAME FILE commands to specify the path name on the

destination host. If the file systems on the destination system are set up to have the same paths as the source host, then do not use ALTER DATABASE RENAMEFILE for those files restored to the same path as on the source host.c. Perform a SET UNTIL operation to limit recovery to the end of the archived redo logs. The recovery stops with an error if no SET UNTIL command is specified.d. Restore and recover the database.e. Run the SWITCH DATAFILE ALL command so that the control file recognizes the new path names as the official new names of the data files.

Example 20-3 shows the RMAN script reco_test.rman that can perform the restore and recovery operation.Example 20-3 Restoring a Database on a New Host:

RUN{# allocate a channel to the tape deviceALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS '...';# rename the data files and online redo logsSET NEWNAME FOR DATAFILE 1 TO '?/oradata/test/system01.dbf'; SET NEWNAME FOR DATAFILE 2 TO '?/oradata/test/undotbs01.dbf'; SET NEWNAME FORDATAFILE 3 TO '?/oradata/test/cwmlite01.dbf'; SET NEWNAME FOR DATAFILE 4 TO '?/oradata/test/drsys01.dbf'; SET NEWNAME FOR DATAFILE 5 TO '?/oradata/test/example01.dbf'; SET NEWNAME FOR DATAFILE 6 TO '?/oradata/test/indx01.dbf'; SET NEWNAME FOR DATAFILE 7 TO '?/oradata/test/tools01.dbf';SET NEWNAME FOR DATAFILE 8 TO '?/oradata/test/users01.dbf'; SQL "ALTER DATABASE RENAME FILE ''/dev3/oracle/dbs/redo01.log'' TO ''?/oradata/test/redo01.log'' ";SQL "ALTER DATABASE RENAME FILE ''/dev3/oracle/dbs/redo02.log'' TO ''?/oradata/test/redo02.log'' ";

# Do a SET UNTIL to prevent recovery of the online logs SET UNTIL SCN 123456;# restore the database and switch the data file names RESTORE DATABASE;SWITCH DATAFILE ALL;# recover the databaseRECOVER DATABASE;}EXIT

12. Execute the script created in the previous step.

For example, start RMAN to connect to the target database and run the @ command:% rman TARGET / NOCATALOGRMAN> @reco_test.rman13. Open the restored database with the RESETLOGS option. From the RMAN prompt, open the database with the RESETLOGS option:ALTER DATABASE OPEN RESETLOGS;Caution:When you re-open your database in the next step, do not connect to the recovery catalog. Otherwise, the new database incarnation created is registeredautomatically in the recovery catalog, and the file names of the production database are replaced by the new file names specified in the script.14. Optionally, delete the test database with all of its files.Note:If you used an ASM disk group, then the DROP DATABASE command is the only way to safely remove the files of the test database. If you restored to non-ASMstorage then you can also use operating system commands to remove the database.Use the DROP DATABASE command to delete all files associated with the database automatically. The following example deletes the database files:STARTUP FORCE NOMOUNT PFILE='?/oradata/test/inittrgta.ora'; DROP DATABASE;

Because you did not perform the restore and recovery operation when connected to the recovery catalog, the recovery catalog contains no records for any of the

restored files or the procedures performed during the test. Likewise, the control file of the trgta database is completely unaffected by the test.

QUESTION 138You need to configure fine-grained access control to external network resources from within your database. You create an access control list (ACL) using theDBMS_NETWORK_ACL_ADMIN package.

Which statement is true regarding the ACL created?

A. It is a list of remote database links stored in the XML file that are available to the users of the database.B. It is a list of users and network privileges stored in the XML file according to which a group of users canconnect to one or more hosts.C. It is a list of users and network privileges stored in the data dictionary according to which a group of userscan connect to one or more hosts.D. It is the list of the host names or the IP addresses stored in the data dictionary that can connect to yourdatabase through PL/SQL network utility packages such

as UTL_TCP.


Explanation/Reference:Explanation:The DBMS_NETWORK_ACL_ADMIN package provides the interface to administer the network Access ControlList (ACL).Refer to here for About Fin-Grained Access to External Network ServicesConfiguring fine-grained access control for users and roles that need to access externalnetwork services fromthe database. This way, specific groups of users can connect to one or more host computers, based onprivileges that you grant them.Typically, you use this feature to control access to applications that run onspecific host addresses.To configure fine-grained access control to external network services, you create an access control list (ACL),which is stored in Oracle XML DB. You can create theaccess control list by using Oracle XML DB itself, orby using the DBMS_NETWORK_ACL_ADMIN and DBMS_NETWORK_ACL_UTILITY PL/SQL packages. Thisguideexplains how to use these packages to create and manage the access control list. To create an access controllist by using Oracle XML DB and for generalconceptual information about access control lists, see Oracle XMLDB Developer's Guide.
