QUESTION 2You are using Recovery Manager (RMAN) for backup and recovery operations with a recovery catalog. Youhave been taken database backups every evening. On November 15, 2007, at 11:30 AM, you wereinformed that the USER_DATA tablespace was accidentally dropped. On investigation, you found that thetablespace existed until 11:00 AM, and important transactions were done after that.

So you decided to perform incomplete recovery until 11:00 AM. All the archive logs needed to performrecovery are intact. In NOMOUNT state you restored the control file that has information about theUSER_DATA tablespace from the latest backup. Then you mounted the database.Identify the next set of commands that are required to accomplish the task?

QUESTION 10You created a database with the Database Configuration Assistant (DBCA) by using one of the defaulttemplates.

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

A. USERSB. SYSTEMC. SYSAUXD. EXAMPLEE. SAMPLE


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

QUESTION 11While exporting data with Data Pump, you find that the export takes longer than expected. You decide tostop the job and restart it during off-peak hours.

Which view would you query to determine the name and status of the stopped job?

A. DBA_JOBSB. V$SESSIONC. V$SESSION_LONGOPSD. DBA_DATAPUMP_JOBSE. DBA_DATAPUMP_SESSIONS

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Explanation:When a Datapump Export or Import session is launched, a Datapump Job is automatically tarted. This way,we can:* detach from and reattach to long-running jobs without affecting the job itself.* monitor jobs from multiple locations* stop a job: suspend it temporarily to leave other applications requesting more resources to get themrestart itlater* kill any Datapump job anytime* see the progress of the import or export operations

11. SELECT e.emplyee_id, e.first_name, e.last_name, d.department_name

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 EXTERNALstatement. When you create an external table, you specify the followingattributes:1. TYPE - specifies the type of external table. The two available types are the ORACLE_LOADER type andthe ORACLE_DATAPUMP type. Each type of external table is supported by its own access driver.* The ORACLE_LOADER access driver is the default. It can perform only data loads, and the data mustcomefrom text datafiles. Loads from external tables to internal tables are done by reading from the externaltables' text-only datafiles .* The ORACLE_DATAPUMP access driver can perform both loads and unloads. The data must come frombinary dump files. Loads to internal tables from external tables are done by fetching from the binary dumpfiles. Unloads from internal tables to external tables are done by populating the external tables' binary dumpfiles.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 a directory path.3. ACCESS PARAMETERS - describe the external data source and implements the type of external tablethat was specified. Each type of external table has its own access driver that provides access parametersunique to that type of external table.4. LOCATION - specifies the location of the external data. The location is specified as a list of directoryobjects and filenames. If the directory object is not specified, then the default directory object is used as thefile location.

QUESTION 15View the Exhibits exhibit1 and exhibit2.

Both the processes use PROG_1 as the job template that is already available. The time taken by the jobsare recorded in the TEST_LOG table. While comparing the time taken to create the jobs, the process inexhibit1 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 16Which 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. Recovery Manager (RMAN) is used to convert the necessary data files of the database if the target

platform is different and has different endian format

QUESTION 25Which 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.

Correct Answer: BC

Section: (none)Explanation

Explanation/Reference:Explanation:Online PatchingRegular patches typically contain .o (object) files and/or .a (archive) libraries, and therefore require a relinkof the RDBMS binary. Online patches, however, contain .so files, which are dynamic/shared libraries, anddo not require a relink of the RDBMS binary. Consequently, since a relink is not needed, you can apply orroll back online patches while the RDBMS instance is running. This simplifies administration, because nodowntime is needed, and also results in a much quicker turnaround time for installing or de-installing OnlinePatches.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 install an online patch in just a few seconds.Online patches are only applicable for Oracle RDBMS and not any other products. Online patches arecurrently supported on the following Windows and UNIX platforms 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 thepatch fixes could reappear after you apply another patch. This is called a conflict situation. OPatch detectssuch situations and raises an error when it detects a conflict.

QUESTION 26In Recovery Manager (RMAN), you are taking Image copies of the data files of your production databaseand rolling them forward at regular intervals. You attempt to restart your database. After a regularmaintenance task, you realize that one of the data files that belongs to the USERS tablespace is damagedand you need to recover the data file by using the image copy.

Because a media failure caused the data file to be damaged, you want to place the data file in a differentlocation while restoring the file. Which option must you consider for this task?

A. using only the RMAN SWITCH command to set the new location for the data fileB. placing the database in the MOUNT state for the restore and recovery operations.C. using an RMAN RUN block with the SET NEWNAME and then the SWITCH command.D. configuring two channels: one for the restore operation and the other for the recovery operation

On November 23, 2007, you issue the RMAN command to back up the database to disk. Which statementis true regarding the backup of the TOOLS tablespace?

A. The RMAN backup fails because the TOOLS tablespace is read-onlyB. The RMAN skips the backup of the tablespace because backup optimization is enabledC. The RMAN makes backup because optimization can be enabled only for backups to diskD. The RMAN makes the backup because no backup of the tablespace exists within the seven day window



QUESTION 28Multiple RMAN sessions are connected to the database instance. Examine the following output whenbackup commands are running in server sessions: What could have helped you to correlate serversessions with channels?

A. Implement RMAN multiplexingB. Set the DEBUG ON in the RMAN scriptC. Specify the command ID in the RMAN scriptD. Use a tag with the RMAN BACKUP command

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 queueSYS.SCHEDULER$_EVENT_QUEUE. This queue is a secure queue and is owned by SYS. To create asubscription 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 theagent that you used to subscribe to the events queue, and db_username is the user for whom you want tocreate a subscription.There is no need to grant dequeue privileges to the user. The dequeue privilege is granted on theScheduler event queue to PUBLIC.

QUESTION 42You 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 a tape drive on a daily basis. Because of mediafailure, you lost your production database completely along with the recovery catalog database. You want torecover the target database and make it functional. You consider performing the following steps toaccomplish 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?

A. 8, 1, 3, 2, 4, 5, 7, 6B. 1, 8, 3, 4, 2, 5, 7, 6C. 1, 3, 4, 2, 8, 5, 6, 7D. 1, 3, 2, 4, 6, 5, 7, 8


Explanation/Reference:Explanation:Recovering the Database After a DisasterThe procedure for disaster recovery is similar to the procedure for recovering the database with a backupcontrol file in NOCATALOG mode. If you are restoring the database to a new host, then you should alsoreview the considerations described in "Restoring a Database on a New Host". This scenario assumes thatthe Linux server on which your database was running has been damaged beyond repair. Fortunately, youbacked up the database to Oracle Secure Backup and have the tapes available. The scenario assumes thefollowing:

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 apassword file.2. Start RMAN and connect to the target database instance. At this stage, no initialization parameter fileexists. If you have set ORACLE_SID and ORACLE_HOME, then you can use operating systemauthentication 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 theServer 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 serverparameter 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 NoRecovery Catalog").c. Mount the restored control file.d. Catalog any backups not recorded in the repository with the CATALOG command. e. Restore the datafiles to their original locations. If volume names have changed, then run SET NEWNAME commandsbefore the restore operation and perform a switch after the restore operation to update the control file withthe new locations 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 thisway RMAN restores the database # to the same structure 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 therestored 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 2TO '/dev/vgd_1_0/rlvt5_500M_2'; SET NEWNAME FOR DATAFILE 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 58Which two statements are true about a duplicate database that is created by using the DUPLICATEcommand 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 DuplicationDatabase duplication is the use of the DUPLICATE command to copy all or a subset of the data in a sourcedatabase. The duplicate database (the copied database) functions entirely independently from the sourcedatabase (the database being copied).Purpose of Database DuplicationIf you copy a database with operating system utilities instead of the DUPLICATE command, then the DBIDof the copied database remains the same as the original database. To register the copy database in thesame recovery catalog with the original, you must change the DBID with the DBNEWID utility (see OracleDatabase Utilities). In contrast, the DUPLICATE command automatically assigns the duplicate database adifferent DBID so that it can be registered in the same recovery catalog as the source database.Backup-Based DuplicationIn backup-based duplication, RMAN creates the duplicate database by using pre-existing RMAN backupsand copies. This technique of duplication uses one of the following mutually exclusive subtechniques:Duplication without a target database connection, RMAN obtains metadata about backups from a recoverycatalog.Duplication without a target database connection and without a recovery catalog. RMAN obtains metadata

about where backups and copies reside from BACKUP LOCATION. Duplication with a target databaseconnection. RMAN obtains metadata about backups from the target database control file or from therecovery catalog.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 the auxiliary instance on the destination host. For activedatabase duplication the primary work is performed by target channels. RMAN must perform databasepoint-in-time recovery, even when no explicit point in time is provided for duplication. Point-in-time recoveryis required because the online redo log files in the source database are not backed up and cannot beapplied to the duplicate database. The farthest point of recovery of the duplicate database is the mostrecent redo log file 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 UNTILclause 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. Thisstep applies to backup-based duplication.5. Restores and copies the duplicate data files and recovers them with incremental backups and archivedredo 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 newdatabase.

QUESTION 59View 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 moreinformation, 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 back online. By default, Oracle ASM drops a disk in 3.6hours 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 60Which 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 asOracle bypasses the operating system and generates exactly the requests it needs (no user configurationor 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 61Identify two options that Oracle recommends while configuring the backup and recovery environment foryour recovery catalog. (Choose two.)

A. configuring control file autobackup to be ONB. backing up data filed only and not the archived redo log filesC. 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. Therecovery catalog is stored in the default tablespace of the schema. The SYS user cannot be the owner ofthe recovery catalog.Decide which database you will use to install the recovery catalog schema, and also how you will back upthis database. Also, decide whether to operate the catalog database in ARCHIVELOG mode, which isrecommended.Note: Do not use the target database to be backed up as the database for the recovery catalog. Therecovery catalog must be protected if the target database is lost.

QUESTION 62UNDO__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 66During the installation of Oracle Database 11g, you do not set ORACLE_BASE explicitly. You selected theoption to create a database as part of the installation. How would this environment variable setting affectthe installation?

A. The installation terminates with an error.B. The installation proceeds with the default value without warnings and errors.C. The installation proceeds with the default value but it would not be an OFA-compliant database.D. The installation proceeds with the default value but a message would be generated in the alert log file.



QUESTION 67You 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 followingcommand to change the DISK_REPAIR_TIME attribute from 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 theDISK_REPAIR_TIME Disk Group Attribute Appropriately. The DISK_REPAIR_TIME disk group attributespecifies 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 ONLINEDISK command and Oracle ASM resynchronizes the stale data from the mirror side. In Oracle Database11g, the online disk operation does not restart if there is a failure of the instance on which the disk isrunning. You must reissue the command manually to bring the disk online.

The backup was taken after the data files was taken offline-normal or is in the read only modeD. The data file backup complies with the back retention policy and the backup duplexing feature



QUESTION 72Your production database is functional on the SHOST1 host. You are backing up the production databaseby using Recovery Manager (RMAN) with the recovery catalog. You want to replicate the productiondatabase 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 youdo to restore and recover the backup for the test environment?

A. Restoring the control file from the backup by using the NOCATALOG option to restore, and recoveringthe data files

B. Restoring the data files by using the NOCATALOG option and using the SET NEWNAME command tochange the location

C. 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 SETDBID 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 parameterfile '/net/hostb/oracle/dbs/inittrgta.ora' trying to start the Oracle 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 parameterfile and use the SET command to indicate the location of the autobackup (in this example, the autobackupis in /tmp):

RUN{ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS '...';SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/tmp/%F'; RESTORESPFILETO 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 directorystructure. 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 initializationparameter.9. Catalog the data file copies that you copied in "Restoring Disk Backups to a New Host", using their newfile names or CATALOG START WITH (if you know all the files are in directories with a common prefixeasily 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:

CATALOG DATAFILECOPY'/oracle/oradata/trgt/system01.dbf', '/oracle/oradata/trgt/undotbs01.dbf', '/oracle/oradata/trgt/cwmlite01.dbf','/oracle/oradata/trgt/drsys01.dbf', '/oracle/oradata/trgt/example01.dbf', '/oracle/oradata/trgt/indx01.dbf', '/oracle/oradata/trgt/tools01.dbf', '/oracle/oradata/trgt/users01.dbf';

10. Start a SQL*Plus session on the new database and query the database file names recorded in thecontrol file.Because the control file is from the trgta database, the recorded file names use the original hosta filenames. You can query V$ views to obtain this information. Run the 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 sourcehost, use a SET NEWNAME command to specify the new path on the destination host. If the file systemson the destination system are set up to have the same paths as the source host, then do not use SETNEWNAME for those files restored to the same path as on the source host. b. For each online redo log thatis to be created at a different location than it had on the source host, use SQL ALTER DATABASERENAME 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 thesource host, then do not use ALTER DATABASE RENAME FILE for those files restored to the same pathas on the source host.c. Perform a SET UNTIL operation to limit recovery to the end of the archived redo logs. The recovery stopswith 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 asthe 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 2TO '?/oradata/test/undotbs01.dbf'; SET NEWNAME FOR DATAFILE 3 TO '?/oradata/test/cwmlite01.dbf';SET NEWNAME FOR DATAFILE 4 TO '?/oradata/test/drsys01.dbf'; SET NEWNAME FOR DATAFILE 5TO '?/oradata/test/example01.dbf'; SET NEWNAME FOR DATAFILE 6 TO '?/oradata/test/indx01.dbf'; SETNEWNAME 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'' ";

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 databasewith 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, thenew database incarnation created is registered automatically in the recovery catalog, and the file names ofthe 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 thefiles of the test database. If you restored to non-ASM storage then you can also use operating systemcommands to remove the database.Use the DROP DATABASE command to delete all files associated with the database automatically. Thefollowing 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 duringthe test. Likewise, the control file of the trgta database is completely unaffected by the test.

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 AccessControlList (ACL).Refer to here for About Fin-Grained Access to External Network ServicesConfiguring fine-grained accesscontrol for users and roles that need to access external network services fromthe database. This way,specific groups of users can connect to one or more host computers, based onprivileges that you grantthem. 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 the access control list by using Oracle XML DBitself, orby using the DBMS_NETWORK_ACL_ADMIN and DBMS_NETWORK_ACL_UTILITY PL/SQLpackages. This guideexplains how to use these packages to create and manage the access control list. Tocreate an access controllist by using Oracle XML DB and for general conceptual information about accesscontrol lists, see Oracle XMLDB Developer's Guide.

QUESTION 104You are using the flash recovery area (fast recovery area in 11g Release 2) to store backup related files inyour database. After regular monitoring of space usage in the Mash recovery area. You realize that theflash recovery area is (jetting filled up very fast and it is running out of space. Your database flash recoveryarea is low 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 [Choosetwo]

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



QUESTION 105Which 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*';


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 singleALTERDISKGROUP statement are recommended. Grouping operations in a single ALTER DISKGROUPstatement can reduce rebalancing operations. Oracle ASM automatically rebalances when the configurationof a disk group changes. By default, the ALTER DISKGROUP statement does not wait until the operation iscomplete 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 as part 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 rebalancethe disk group. When you drop a disk, Oracle ASM relocates all the data from the disk and clears the diskheader so that it no longer is part of the disk group. The disk header is not cleared if you specify theFORCE keyword.

QUESTION 106Before 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

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, childrenarebacked out before parents are backed out). Without CASCADE, if any dependent transaction is notspecified, 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 statementsforspecified transactions in reverse order of commit times.If no constraints break and you are satisfied withthe 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.
