2 Exam A QUESTION 1 To 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. Correct Answer: CD /Reference: QUESTION 2 You are using Recovery Manager (RMAN) for backup and recovery operations with a recovery catalog. You have been taken database backups every evening. On November 15, 2007, at 11:30 AM, you were informed that the USER_DATA tablespace was accidentally dropped. On investigation, you found that the tablespace 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 perform recovery are intact. In NOMOUNT state you restored the control file that has information about the USER_DATA tablespace from the latest backup. Then you mounted the database. Identify the next set of commands that are required to accomplish the task?

3 A. Option A B. Option B C. Option C D. Option D Correct Answer: A /Reference: : QUESTION 3 Which statement is true about a running session that belongs to the online transaction processing (OLTP) group?

4 A. It permanently switches to the low_group consumer group if the session exceeds 10,000 I/O requests or 2,500 MB of data transfer. B. It performs the first I/O requests or 2,500 MB of data transfer in the LOW-GROUP consumer group, and then switches to the original group. C. It switches to the LOW_GROUP consumer group if the session exceeds I/O requests or 2500 MB of data transfer and returns to the original group after the operation. D. It switches to the LOW_GROUP consumer group if the session exceeds I/O requests or 2500 MB of data transfer for queries, but not for data manipulation language (DML) operations. Correct Answer: C /Reference: answer is verified. QUESTION 4 View the Exhibit to examine the replay settings for replay parameters. What is the implication for setting the values for replay parameters? (Choose all that apply.) Exhibit:

5 A. The COMMIT order in the captured workload is preserved during replay. B. The value 100 in the THINK_TIME_SCALE parameter attempts to make the replay client shorten the think time between calls. C. The value 100 in the CONNECT_TIME_SCALE parameter attempts to connect all sessions as captured. D. The value 100 in the THINK_TIME_SCALE parameter attempts to match the captured user think time while replaying. E. The value 100 in the CONNECT_TIME_SCALE parameter attempts to connect all sessions immediately as soon as the replay begins. Correct Answer: ACD /Reference: : QUESTION 5 In your production database, users report that they are unable to generate reports on an important table because it does not contain any data. While investigating the reason, you realize that another user executed the TRUNCATE TABLE command, which accidentally caused the data to be lost. Now you want to recover the lost data of the table without affecting objects in other schemas. Which method must you use to recover the lost data? A. Complete Recovery with online redo log B. Complete Recovery with archived redo log C. Tablespace Point-in-Time Recovery (TSPITR) D. Incomplete Recovery with system change number (SCN) Correct Answer: C /Reference:

It produces an error because a fully qualified host name needs to be specified. B. It produces an error because the range of ports associated with the hosts has not been specified. C. It creates an access control list (ACL) with the user ACCT_MGR who gets the CONNECT and RESOLVE privileges. D. It creates an access control list (ACL) with the user ACCT_MGR who gets the CONNECT privilege but not the RESOLVE privilege. Correct Answer: C /Reference: : QUESTION 7 What two are the prerequisites for enabling Flashback Database? A. The database must be in ARCHIVELOG mode B. The database must be in MOUNT EXCLUSIVE mode C. The database must be opened in RESTRICTED mode D. The database instance must be started in the NOMOUNT state E. The database instance must have the keep buffer pool defined Correct Answer: AB /Reference: : QUESTION 8 Which statements are true regarding system-partitioned tables? (Choose all that apply.) A. Only a single partitioning key column can be specified. B. All DML statements must use partition-extended syntax. C. The same physical attributes must be specified for each partition.

7 D. Unique local indexes cannot be created on a system-partitioned table. E. Traditional partition pruning and partitionwise joins are not supported on these tables. Correct Answer: DE /Reference: : QUESTION 9 The database users regularly complain about the difficulty in performing transactions. On investigation, you find that some users perform long-running transactions that consume huge amounts of space in the undo tablespace, which caused the problem. You want to control the usage of the undo tablespace only for these user sessions and you do not want these sessions to perform long-running operations. How would you achieve this? A. Implement a profile for the users. B. Implement external roles for the users. C. Set the threshold for the undo tablespace. D. Implement a Database Resource Manager plan. Correct Answer: B /Reference: : QUESTION 10 You 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. USERS B. SYSTEM C. SYSAUX D. EXAMPLE E. SAMPLE Correct Answer: A /Reference: : USERS This tablespace is used to store permanent user objects and data. Like the TEMP tablespace, every database should have a tablespace for permanent user data that is assigned to users. Otherwise, user objects will be created in the SYSTEM tablespace, which is not good practice. In the preconfigured database, USERS is assigned the default tablespace, and space for all objects created by non-system users comes from this tablespace. For system users, the default permanent tablespace remains SYSTEM. REF.: Oracle(r) 10g 2 Days DBA, 6-7 QUESTION 11 While exporting data with Data Pump, you find that the export takes longer than expected. You decide to stop the job and restart it during off-peak hours. Which view would you query to determine the name and status of the stopped job?

8 A. DBA_JOBS B. V$SESSION C. V$SESSION_LONGOPS D. DBA_DATAPUMP_JOBS E. DBA_DATAPUMP_SESSIONS Correct Answer: D /Reference: : 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 them restart itlater * kill any Datapump job anytime * see the progress of the import or export operations REF.: Metalink Note: QUESTION 12 Note the output of the following query: SQL> SELECTflashback_archive_name,status FROM dba_flashback_archive; FLASHBACK_ARCHIVE_NAMESTATUS FLA1 You executed the following command to enable Flashback Data Archive on the EXCHANGE_RATE table: ALTERTABLEexchange_rateFLASHBACK ARCHIVE; What is the outcome of this command? A. The table uses the default Flashback Data Archive. B. The Flashback Data Archive is created in the SYSAUX tablespace. C. The Flashback Data Archive is created in the same tablespace where the tables are stored. D. The command generates an error because no Flashback Data Archive name is specified and there is no default Flashback Data Archive.

FROM employees e, departments d; Which line of the command would cause an error? A. line 2, because the column names have been specified B. line 7, because file name must have a.dat extension C. line 3, because ORGANIZATION EXTERNAL has been specified D. line 9, because the PARALLEL option cannot be specified with one file name E. line 12, because there is no join defined between EMPLOYEES and DEPARTMENTS table F. line 5, because ORACLE_LOADER is not a valid structure for external table creation with the SELECT statement Correct Answer: F /Reference: : External tables are created using the SQL CREATE TABLE...ORGANIZATION EXTERNAL statement. 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 and the 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 must comefrom text datafiles. Loads from external tables to internal 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 external tables 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 a directory 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 own access 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.

A. the SYSTEM tablespace

10 B. the default permanent tablespace for the non-system users C. an offline tablespace D. a temporary tablespace E. a read-only tablespace F. an undo tablespace Correct Answer: BDEF /Reference: : QUESTION 15 View 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 comparing the 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):

11 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. Correct Answer: C /Reference: : The difference between two blocks of code is the "JOB_STYLE". The lightweight job creates less metadata for the jobs. QUESTION 16 Which two statements are correct about database transportation? (Choose two.) A. The source and target platforms must be the same B. Redo logs, control files and temp files are also transported C. The transported database must have the same database identifier (DBID) as the source database and cannot be changed D. The COMPATIBLE parameter must be set to or higher and the database must be opened in readonly mode before being transported E. 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 Correct Answer: DE /Reference: : QUESTION 17

A. The EVEN parameter was not set. B. The SQL_TRACE parameter is set to FALSE. C. Enterprise Manager is not used. D. The STATISTICS_LEVEL parameter is set to BASIC. E. The TIMED_STATISTICS parameter is set to FALSE. Correct Answer: D /Reference: : QUESTION 25 Which 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

16 /Reference: : Online Patching Regular 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 back online patches while the RDBMS instance is running. This simplifies administration, because no downtime is needed, and also results in a much quicker turnaround time 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 install an 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 UNIX platforms for version 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 26 In Recovery Manager (RMAN), you are taking Image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database. After a regular maintenance task, you realize that one of the data files that belongs to the USERS tablespace is damaged and 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 different location 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 file B. 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 Correct Answer: C /Reference: : QUESTION 27 Consider the following scenario for your database: Real 59 Oracle 1z0-034 Exam - Backup optimization is enabled in RMAN. - The recovery window is set to 7 days in RMAN. - The most recent backup to disk for the TOOLS tablespace was taken on November 3, The TOOLS tablespace is read-only since November 4, On November 23, 2007, you issue the RMAN command to back up the database to disk. Which statement is true regarding the backup of the TOOLS tablespace? A. The RMAN backup fails because the TOOLS tablespace is read-only B. The RMAN skips the backup of the tablespace because backup optimization is enabled C. The RMAN makes backup because optimization can be enabled only for backups to disk D. The RMAN makes the backup because no backup of the tablespace exists within the seven day window

17 Correct Answer: D /Reference: : QUESTION 28 Multiple RMAN sessions are connected to the database instance. Examine the following output when backup commands are running in server sessions: What could have helped you to correlate server sessions with channels? A. Implement RMAN multiplexing B.

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. Correct Answer: D /Reference: Consuming Job State Events with your Application To consume job state events, your application must subscribe to the Scheduler event queue SYS.SCHEDULER$_EVENT_QUEUE. This queue is a secure queue and 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 41 Which three elements can a job chain process involve?

If you are restoring the database 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 Linux server on which your database was running has been damaged beyond repair. Fortunately, you backed up the database to Oracle Secure Backup and have the tapes available. The scenario assumes the following:

24 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: % rman RMAN> 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 ; 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 have changed, then run SET NEWNAME commands before the restore operation and perform a switch after the restore operation to update the control file with the 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 manager ALLOCATE 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 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 the restored data files: RMAN> RUN { # If you must restore the files to new locations,

25 # 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 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.

(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. Correct Answer: AC /Reference: : Duplicating a Database Overview 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 copied database) functions entirely independently from the source database (the database being copied). Purpose of Database Duplication If 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 original database. To register the copy database in the same recovery catalog with the original, you must change the DBID with the DBNEWID utility (see Oracle Database Utilities). In contrast, the DUPLICATE command automatically assigns the duplicate database a different DBID so that it can be registered in the same recovery catalog as the source database. Backup-Based Duplication In backup-based duplication, RMAN creates the duplicate database by using pre-existing RMAN backups and 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 recovery catalog. Duplication without a target database connection and without a recovery catalog. RMAN obtains metadata

32 about where backups and copies reside from BACKUP LOCATION. Duplication with a target database connection. RMAN obtains metadata about backups from the target database control file or from the recovery catalog. How RMAN Duplicates a Database For 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 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 source database 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 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 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 59 View Exhibit1 to examine the CRS11G disk group when all the disks are online.
