Question 1:

Which two statements are true about scheduling operations in a pluggable database (PDB)?

A. Scheduler jobs for a PDB can be defined only at the container database (CDB) level.

B. A job defined in a PDB runs only if that PDB is open.

C. Scheduler attribute setting is performed only at the CDB level.

D. Scheduler objects created by users can be exported or imported using Data Pump.

E. Scheduler jobs for a PDB can be created only by common users.

Correct Answer: BD

In general, all scheduler objects created by the user can be exported/imported into the PDB using a data pump. Predefined scheduler objects will not get exported and that means that any changes made to these objects by the user will have to be made once again after the database has been imported into the pluggable database.

However, this is how to import/export works currently. A job defined in a PDB will run only if a PDB is open.


Question 2:

A complete database backup to media is taken for your database every day. Which three actions would you take to improve backup performance?

A. Set the backup_tape_io_slaves parameter to true.

B. Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.

C. Configure a large pool if not already done.

D. Remove the rate parameter, if specified, in the allocate channel command.

E. Always use RMAN compression for tape backups rather than the compression provided by the media manager.

F. Always use synchronous I/O for the database.

Correct Answer: BCD

Tuning RMAN Backup Performance: Procedure Many factors can affect backup performance. Often, finding the solution to a slow backup is a process of trial and error. To get the best performance for a backup, follow the suggested steps in this section:

Step 1: Remove RATE Parameters from Configured and Allocated Channels

Step 2: If You Use Synchronous Disk I/O, Set DBWR_IO_SLAVES

Step 3: If You Fail to Allocate Shared Memory, Set LARGE_POOL_SIZE Step 4: Tune RMAN Tape Streaming Performance Bottlenecks Step 5: Query V$ Views to Identify Bottlenecks

Reference:https://docs.oracle.com/database/121/BRADV/rcmtunin.htm#BRADV172


Question 3:

For which three pieces of information can you use the RMAN list command?

A. stored scripts in the recovery catalog

B. available archived redo log files

C. backup sets and image copies that are obsolete

D. backups of tablespaces

E. backups that are marked obsolete according to the current retention policy

Correct Answer: ABD

Explanation: About the LIST Command: The primary purpose of the LIST command is to list backups and copies. For example, you can list: -Backups and proxy copies of a database, tablespace, datafile, archived redo log, or control file – Backups that have expired -Backups restricted by time, path name, device type, tag, or recoverability -Archived redo log files and disk copies

Reference:http://docs.oracle.com/cd/ B28359_01/backup.111/b28270/crept.htm#BRADV89585


Question 4:

Which three statements are true about a job chain?

A. It can contain a nested chain of jobs.

B. It can be used to implement dependency-based scheduling.

C. It cannot invoke the same program or nested chain in multiple steps in the chain.

D. It cannot have more than one dependency.

E. It can be executed using event-based or time-based schedules.

Correct Answer: ABE

Chains are the means by which you can implement dependency-based scheduling, in which jobs are started depending on the outcomes of one or more previous jobs. DBMS_SCHEDULER.DEFINE_CHAIN_STEP DBMS_SCHEDULER.DEFINE_CHAIN_EVENT_STEP

Reference: http://docs.oracle.com/cd/B28359_01/server.111/b28310/scheduse009.htm#ADMIN12


Question 5:

Because of logical corruption of data in a table, you want to recover the table from an RMAN backup to a

specified point in time.

Examine the steps to recover this table from an RMAN backup:

1. Determine which backup contains the table that needs to be recovered.

2. Issue the recover table RMAN command with an auxiliary destination defined and the point in time

specified.

3. Import the Data Pump export dump file into the auxiliary instance.

4. Create a Data Pump export dump file that contains the recovered table on a target database.

Identify the required steps in the correct order.

A. 1, 4, 3

B. 1, 2

C. 1, 4, 3, 2

D. 1, 2, 4

Correct Answer: D

Because according to oracle PDFs if you run the restore table … auxiliary impede and rename can be included. So there is no reason to make the import manually if it can be already included in step 2.

Reference: https://docs.oracle.com/database/121/BRADV/rcmresind.htm#BRADV689


Question 6:

Examine the command:

SQL> RECOVER DATABASE USING BACKUP CONTROL FILE UNTIL CANCEL;

In which two scenarios is this command required?

A. The current online redo log file is missing.

B. A data file belonging to a noncritical tablespace is missing.

C. All the control files are missing.

D. The database backup is older than the control file backup.

E. All the data files are missing.

Correct Answer: AC

Question 7:

Which two are prerequisites for setting up Flashback Data Archive?

A. Fast Recovery Area should be defined.

B. Undo retention guarantee should be enabled.

C. Supplemental logging should be enabled.

D. Automatic Undo Management should be enabled.

E. All users using Flashback Data Archive should have an unlimited quota on the Flashback Data Archive tablespace.

F. The tablespace in which the Flashback Data Archive is created should have Automatic Segment Space Management (ASSM) enabled.

Correct Answer: DF

There are a number of restrictions for flashback archives: The tablespaces used for a flashback archive must use local extent management and automatic segment space management. The database must use automatic undo management. Reference: http://www.dba-oracle.com/t_11g_new_enabling_fdba.htm


Question 8:

The environmental variable oracle_Base is set to /u01/app/oracle and oracle_home is set to /u01/app/ oracle/product/12.1.0/db1.

You want to check the diagnostic files created as part of the Automatic Diagnostic Repository (ADR). Examine the initialization parameters set in your database.

NAME TYPE VALUE

audit_file_deststring/u01/app/oracle/admin/eml2rep/dump background_dump_deststring core_dump_deststring db_create_file_deststring db_recovery_file_deststring/u01/app/oracle/fast_recovery_area diagnostic_deststring

What is the location of the ADR base?

A. It is set to/u01/app/oracle/product:/12.1.0/db_1/log.

B. It is set to /u01/app/oracle/admin/en12.1.0/dump.

C. It is set to /u01/app/oracle.

D. It is set to /u01/app/oracle/flash_recovery_area.

Correct Answer: C

The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database.

It is therefore available for problem diagnosis when the database is down.

The ADR root directory is known as the ADR base. Its location is set by the DIAGNOSTIC_DEST initialization parameter. If this parameter is omitted or left null, the database sets DIAGNOSTIC_DEST upon startup as follows:

If environment variable ORACLE_BASE is set, DIAGNOSTIC_DEST is set to the directory designated by

ORACLE_BASE.

If the environment variable ORACLE_BASE is not set, DIAGNOSTIC_DEST is set to ORACLE_HOME/log.

Question 9:

You want to export the pluggable database (PDB) hr pdb1 from the multitenant container database (CDB)

CDB1 and import it into the cdb2 CDB as the emp_pdb1 PDB.

Examine the list of possible steps required to perform the task:

1. Create a PDB named emp_pdb1.

2. Export the hr_pdb1 PDB by using the full clause.

3. Open the emp_pdb1 PDB.

4. Mount the emp_pdb1 PDB.

5. Synchronize the emp_pdb1 PDB in restricted mode.

6. Copy the dump file to the Data Pump directory.

7. Create a Data Pump directory in the emp_pdb1 PDB.

8. Import data into emp_pdb1 with the full and remap clauses.

9. Create the same tablespaces in emp_pdb1 as in hr_pdb1 for new local user objects.

Identify the required steps in the correct order.

A. 2, 1, 3, 7, 6, and 8

B. 2, 1, 4, 5, 3, 7, 6, 9, and 8

C. 2, 1, 3, 7, 6, 9, and 8

D. 2, 1, 3, 5, 7, 6, and 8

Correct Answer: C

Because step 2 says that you perform an expdp with the full clause and you don’t need to create the

tablespaces when you perform the impdp. FULL=yes will export tablespace definitions. So no need for step 9.

Reference: https://docs.oracle.com/cd/B10501_01/server.920/a96652/ch01.htm


Question 10:

You wish to create jobs to satisfy these requirements:

1. Automatically bulk load data from a flat file.

2. Rebuild indexes on the SALES table after completion of the bulk load.

How would you create these jobs?

A. Create both jobs by using Scheduler-raised events.

B. Create both jobs using application-raised events.

C. Create one job to rebuild indexes using application-raised events and another job to perform bulk load using Scheduler raised events.

D. Create one job to rebuild indexes using Scheduler-raised events and another job to perform bulk load by using events raised by the application.

Correct Answer: C

The bulk loader would be started in response to a file watcher scheduler event and the indexes would be rebuilt in response to an application event raised by the bulk loader. Your application can raise an event to notify the Scheduler to start a job. A job started in this way is referred to as an event-based job. The job can optionally retrieve the message content of the event.

Question 11:

Your Oracle 12c multitenant container database (CDB) contains multiple pluggable databases (PDBs). In

the PDB hr_pdb, the common user c##admin and the local user b_admin have only the connect privilege.

You create a common role c##role1 with the create table and select any table privileges.

You then execute the commands:

SQL> GRANTc##role1 TO##Madmin CONTAINER=ALL;

SQL>CONNsys/oracle@HR_PDB as sysdba

SQL> GRANTc##role1TO b_admin CONTAINER=CURRENT;

Which two statements are true?

A. C##admin can create and select any table, and grant the c##role1 role to users only in the root container.

B. B_admin can create and select any table in both the root container and Hr_pdb.

C. c##admin can create and select any table in the root container and all the PDBs.

D. B_admin can create and select any table only in hr_pdb.

E. The grant c##role1 to b_admin command returns an error because the container should be set to ALL.

Correct Answer: CD


Question 12:

Examine the commands executed in the root container of your multitenant container database (CDB) that

has multiple pluggable databases (PDBs):

SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;

SQL> CREATE ROLE c##role1 CONTAINER=ALL;

SQL> GRANT CREATE VIEW TO C##roleI CONTAINER=ALL;

SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL;

SQL> REVOKE c##role1 FROM c##a_admin;

What is the result of the revoke command?

A. It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.

B. It fails and reports an error because the container=all clause is not used.

C. It executes successfully and the c##rocl1 role is revoked from the c##a_admin user in the root database and all the PDBs.

D. It fails and reports an error because the comtainer=current clause is not used.

Correct Answer: B

SQL> REVOKE c##role1 FROM c##a_admin; REVOKE c##role1 FROM c##a_admin * ERROR at line 1: ORA – 01951: ROLE `C##ROLE1\’ not granted to `C##A_ADMIN\’ SQL> REVOKE c##role1 FROM c##a_admin CONTAINER=ALL; Revoke succeeded. SQL> This CREATE USER c##a_admin IDENTIFIED BY orcl123; will create a common user event container that is not specified.


Question 13:

Examine the RMAN command:

RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON; RMAN> BACKUP DATABASE PLUS ARCHIVE LOG;

Which prerequisite must be met before accomplishing the backup?

A. The password for the encryption must be set up.

B. Oracle wallet for the encryption must be set up.

C. All the tablespaces in the database must be encrypted.

D. Oracle Database Vault must be enabled.

Correct Answer: B

Configuration encryption will be used by Transparent encryption. For transparent encryption, you will need to create a wallet, and it must be open. Transparent encryption will then occur automatically after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command.

CONFIGURE ENCRYPTION: You can use this command to persistently configure transparent encryption. You cannot persistently configure dual mode or password mode encryption.

SET ENCRYPTION: You can use this command to configure dual mode or password mode encryption at the RMAN session-level.

Reference:http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH


Question 14:

A database is running in archive log mode. The database contains locally managed tablespaces. Examine the RMAN command:

RMAN> BACKUP AS COMPRESSED BACKUP SET SECTION SIZE 1024M DATABASE;

Which statement is true about the execution of the command?

A. The backup succeeds only if all the tablespaces are locally managed.

B. The backup succeeds only if the RMAN default device for backup is set to disk.

C. The backup fails because you cannot specify the section size for a compressed backup.

D. The backup succeeds and only the used blocks are backed up with a maximum backup piece size of 1024 MB.

Correct Answer: D

COMPRESSED enables binary compression.

RMAN compresses the data written into the backup set to reduce the overall size of the backup set. All backups that create backup sets can create compressed backup sets. Restoring compressed backup sets is no different from restoring uncompressed backup sets.

RMAN applies a binary compression algorithm as it writes data to backup sets. This compression is similar to the compression provided by many media manager vendors. When backing up to a locally attached tape device, compression provided by the media management vendor is usually preferable to the binary compression provided by BACKUP AS COMPRESSED BACKUPSET.

Therefore, use uncompressed backup sets and turn on the compression provided by the media management vendor when backing up to locally attached tape devices. You should not use RMAN binary compression and media manager compression together. Some CPU overhead is associated with compressing backup sets. If the target database is running at or near its maximum load, then you may find the overhead unacceptable.

In most other circumstances, compressing backup sets saves enough disk space to be worth the CPU overhead. SECTION SIZE sizeSpec Specifies the size of each backup section produced during a data file backup.

By setting this parameter, RMAN can create a multisection backup. In a multisection backup, RMAN creates a backup piece that contains one file section, which is a contiguous range of blocks in a file. All sections of a multisection backup are the same size.

You can create a multisection backup for a data file, but not a data file copy. File sections enable RMAN to create multiple steps for the backup of a single large data file. RMAN channels can process each step independently and in parallel, with each channel producing one section of a multisection backup set. 

If you specify a section size that is larger than the size of the file, then RMAN does not use a multisection backup for the file. If you specify a small section size that would produce more than 256 sections, then RMAN increases the section size to a value that results in exactly 256 sections.

Depending on where you specify this parameter in the RMAN syntax, you can specify different section sizes for different files in the same backup job. Note: You cannot use SECTION SIZE with MAXPIECESIZE or with INCREMENTAL LEVEL 1.


Question 15:

In your database, the tbs percent used parameter is set to 60 and the tbs percent free parameter is set to

20.

Which two storage-tiering actions might be automated when using Information Lifecycle Management (ILM) to automate data movement?

A. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used

B. Setting the target tablespace to read-only after the segments are moved

C. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds the TBS percent used

D. Taking the target tablespace offline after the segments are moved

E. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used

Correct Answer: BC

The threshold for activating tiering policies is based on two parameters: TBS PERCENT USED and TBS PERCENT FREE Both values can be controlled by the DBMS_ILM_ADMIN package. TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively.

Hence, whenever the source tablespace\’s usage percentage goes beyond 85 percent, any tiering policy specified on its objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free.

Note that it is possible to add a custom condition to tiering policies to enable the movement of data based on conditions other than how full the tablespace is. In addition, the READ ONLY option must be explicitly specified for the target tablespace.

Question 1:

Identify three reasons for using a recovery catalog with Recovery Manager (RMAN). (Choose three.)

A. to store backup information of multiple databases in one place

B. to restrict the amount of space that is used by backups

C. to maintain a backup for an indefinite period of time by using the KEEP FOREVER clause

D. to store RMAN scripts that are available to any RMAN client that can connect to the target database registered in the recovery catalog

E. to automatically delete obsolete backups after a specified period of time

Correct Answer: ACD


Question 2:

Which two statements are true regarding Oracle Data Pump? (Choose two.)

A. EXPDP and IMPDP are the client components of Oracle Data Pump.

B. DBMS_DATAPUMP PL/SQL packages can be used independently of the Data Pump clients.

C. Oracle Data Pump export and import operations can be performed only by users with the SYSDBA privilege.

D. Oracle Data Pump imports can be done from the export files generated in the Original Export Utility.

E. EXPDP and IMPDP use the procedures provided by DBMS_METADATA to execute export and import commands.

Correct Answer: AB

Reference: http://docs.oracle.com/cd/B19306_01/server.102/b14215/dp_overview.htm


Question 3:

Which two statements are true about making RMAN image copies of a database? (Choose two.)

A. They can only be written to disk.

B. They can be made only when the database is running in NOARCHIVELOG mode.

C. They can be made only when the database is in the MOUNT state.

D. They consist of all used and unused blocks in the data files.

E. They can be made only when the database is running in ARCHIVELOG mode.

Correct Answer: AD

An image copy can be written only to disk.

An image copy is the same as data file. The disadvantage of image copy backup mode is that it occupies much space and does not skip unused data blocks. References: http://www.dba-oracle.com/t_rman_10_image_copies.htm


Question 4:

The CATDB12C database contains an Oracle Database 12c catalog schema owned by the RC12C user. The CATDB11 database contains an Oracle Database l1g catalog schema owned by the RC11 user.

A database with DBID=1423241 is registered in the CATDB11 catalog. Both the recovery catalog databases are open.

In the CATDB12c database, you execute the commands:

1Z0-063 exam questions 4

What is the outcome of the import?

A. It fails because the target database and recovery catalog database are of different versions.

B. It succeeds and all global scripts in the RC11 catalog that have the same name as existing global scripts in the RC12C catalog are automatically renamed.

C. It succeeds but the database is not automatically registered in the RC12c catalog.

D. It fails because RMAN is not connected to the target database with DBID=1423241.

Correct Answer: A


Question 5:

You issue the command:

SQL> ALTER DATABASE BACKUP CONTROL FILE TO TRACE;

Which statement is true about the command?

A. It creates a copy of the control file and stores it in the location specified in the diagnostic_dest initialization parameter.

B. It creates a file that contains the SQL statement, which is required to re-create the control file.

C. It updates the alert log file with the location and contents of the control file.

D. It creates a binary backup of the control file.

Correct Answer: B


Question 6:

Examine the commands executed in CDB$ROOT of your multitenant container database (CDB) that has multiple pluggable databases (PDB):

1Z0-063 exam questions 6

Which statement is true about granting the select privilege on the DBA_users view to the c##ROLE1 role?

A. The command fails and gives an error because object privileges cannot be granted to a common user.

B. The command fails because the container is not set to current.

C. The command succeeds and the common user c##admin can create a session and query the DBA_users view in cdb$root and all the PDBs.

D. The command succeeds and the common user c##admin can create a session in cdb$root and all the PDBs, but can only query the dba_users view in cdb$root.

E. The command succeeds and the common user c##admin can create a session and query the DBA_users view only in cdb$root.

Correct Answer: C


Question 7:

You plan to duplicate the multitenant container database (CDB) cdb1 that contains the pluggable database (PDB) SALES:

1Z0-063 exam questions 7

Which two statements are true? (Choose two.)

A. The root and seed databases are included in the duplication.

B. Only the SALES PDB is duplicated as the non-CDB CDBDUP.

C. A backup of the SALES PDB must exist before the execution of the command.

D. An auxiliary instance must have been started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.

E. RMAN must be connected to a recovery catalog for the execution of the command.

Correct Answer: AD

D: When duplicating a whole CDB or one more PDBs:

You must create the auxiliary instance as a CDB. To do so, start the instance with the following declaration in the initialization parameter file: enable_pluggable_database=TRUE

A: To duplicate PDBs, you must create the auxiliary instance as a CDB. To do so, start the instance with

the declaration enable_pluggable_database=TRUE in the initialization parameter file. When you duplicate one or more PDBs, RMAN also duplicates the root (CDB$ROOT) and the seed database (PDB$SEED). The resulting duplicate database is a fully functional CDB that contains the root, the seed database, and the duplicated PDBs.

References: https://docs.oracle.com/database/121/BRADV/rcmdupdb.htm


Question 8:

You create a new database by using the CREATE DATABASE command in SQL *Plus, with the ENABLE PLUGGABLE DATABASE clause specified.

Which statement is true about the database that is created?

A. It is created as a container database (CDB) with CDB$ROOT, PDB$SEED, and a pluggable database (PDB).

B. It is created as a non-CDB that becomes a CDB after the first PDB is plugged in.

C. It is created as a PDB that must be plugged into an existing CDB.

D. It is created as a CDB with the CDB$ROOT and PDB$SEED databases.

Correct Answer: D

The CREATE DATABASE command with the ENABLE PLUGGABLE DATABASE clause indicates that a CDB is being created. The CDB will contain a root (CDB$ROOT) and a seed (PDB$SEED).

References: https://docs.oracle.com/database/121/SQLRF/statements_5005.htm


Question 9:

Your database is running on the host OUSERVER. You back up your database regularly using RMAN and the backups are cataloged in a recovery catalog. For testing purposes, you want to replicate your database to another host, OUSERVER1, with the same directory structure. So, you copy the backups to the new host.

What must you do to make the database operational in OUSERVER1?

A. Restore the control file from the backup by using the CATALOG option, restore the data files by using the SET NEWNAME command, and recover the data files.

B. Restore the data files by using the CATALOG option and use the SET NEWNAME command to change the location.

C. Restore the control file from the backup by using the CATALOG option, and then restore and recover the data files.

D. Restore the data files from the backup by using the recovery catalog, use the SWITCH command to change the location, and recover the data files.

Correct Answer: A

Catalog any backups not recorded in the repository with the CATALOG command.

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.

Note: One way to name duplicate data files is to use the SET NEWNAME command before executing the DUPLICATE command. RMAN supports the following commands, listed in order of precedence:

1. SET NEWNAME FOR DATAFILE and SET NEWNAME FOR TEMPFILE

2. SET NEWNAME FOR TABLESPACE

3. SET NEWNAME FOR THE DATABASE

References: https://docs.oracle.com/database/121/BRADV/rcmadvre.htm


Question 10:

Examine the list of possible steps to transport a tablespace across platforms that have the same compatibility level, character sets, and endian format:

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

2. Export metadata from the source database.

3. Import metadata into the target database.

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

5. Convert data files by using Recovery Manager (RMAN).

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

Identify the required steps in the correct order.

A. 2, 4, and 3

B. 2, 4, 3, and 5

C. 1, 5, 2, 4, 3, and 6

D. 1, 2, 4, 3, and 6

Correct Answer: D

Step 1 (1): To copy tablespaces from one database to another using transportable tablespace, the source tablespaces are first kept in READ-ONLY mode (to ensure data consistency). Once the tablespaces are in READ-ONLY mode, the actual datafiles belonging to the source tablespaces are copied from the source database to the target database (using any available methods like scp, sftp, rcp, etc).

Step 2 (2): Once the tablespace is kept in READ-ONLY mode, we need to generate the metadata export of the tablespaces that need to transport using the DataPump export utility.

Step 3 (4): Once the metadata export is generated on the source database for all the tablespaces that need to be transported, we need to copy the Export Dump file as well as all the datafiles belonging to the tablespaces to be transported to the target database server.

Question 11:

In which three situations must you use a recovery catalog? (Choose three.)

A. when you want to store RMAN global scripts that can be used across multiple databases

B. when you want to restrict the amount of space used by backups

C. when you want to perform incremental backups by using a block change tracking file

D. when you want to list data files that were in a target database at a given time by using the AT clause with the REPORT SCHEMA command

E. when you want to maintain backup metadata longer than the period specified by the CONTROL_FILE_RECORD_KEEP_TIME parameter

Correct Answer: ADE

A: Some RMAN features function only when you use a recovery catalog. For example, you can store RMAN scripts in a recovery catalog. The chief advantage of a stored script is that it is available to any RMAN client that can connect to the target database and recovery catalog. Command files are only available if the RMAN client has access to the file system on which they are stored.

A locally stored script is associated with the target database to which RMAN is connected when the script is created, and can only be executed when you are connected to this target database. A global stored script can be run against any database registered in the recovery catalog.

D: If you use a recovery catalog, then you can use the clause to specify a past time, SCN, or log sequence number, as shown in these examples of the command:

RMAN> REPORT SCHEMA AT TIME \’SYSDATE-14\’; # schema 14 days ago RMAN> REPORT SCHEMA AT SCN 1000; # schema at scn 1000 RMAN> REPORT SCHEMA AT SEQUENCE 100 THREAD 1; # schema at sequence 100 RMAN> REPORT SCHEMA FOR DB_UNIQUE_NAME standby1;

E: The CONTROL_FILE_RECORD_KEEP_TIME initialization parameter determines the minimum number of days that records are retained in the control file before they are candidates for being overwritten. Thus, you must ensure that you resynchronize the recovery catalog with the control file records before these records are erased.

Question 12:

Which three requirements should be successfully met by an Oracle Secure Backup (OSB) user so that OSB performs RMAN backup or restore requests? (Choose three.)

A. RMAN preauthorization on the host

B. OSB encryption for data in transport and on tape

C. matching the OS user identity of the Oracle instance associated with the database username

D. assigned to a class with rights to back up or restore the Oracle database

E. scheduling of the RMAN backup to occur automatically at user-defined intervals

F. assigned to a class with rights to browse all directories and catalogs

Correct Answer: ADF

A: Performing Oracle database backups using RMAN requires RMAN user preauthorization within OSB

D: The preauthorized Oracle Secure Backup user must also be assigned to an Oracle Secure Backup

class possessing the following rights:

access Oracle backups (set to the owner, class, or all)

perform Oracle backups and restores

F: The preauthorized Oracle Secure Backup user must be mapped to operating system privileges to

access the files to be backed up or restored. the preauthorized Oracle Secure Backup user can perform

RMAN operations only on the host where it has access to files.

Question 13:

Which two statements are true about setting the FAST_START_MTTR_TARGET parameter to a nonzero value? (Choose two.)

A. The MTTR advisor is enabled only if the value is greater than the default value.

B. Automatic checkpoint tuning is enabled.

C. The value of the LOG_CHECKPOINT_INTERVAL parameter overrides the value of the FAST_START_MTTR_TARGET parameter.

D. The time is taken to recover an instance after a crash is always exactly the same as the value set for the FAST_START_MTTR_TARGET parameter.

Correct Answer: AC

The FAST_START_MTTR_TARGET initialization parameter lets you specify in seconds the expected

“mean time to recover” (MTTR), which is the expected amount of time Oracle takes to perform a crash or

instance recovery for a single instance.

To enable MTTR advisory, set the initialization parameter FAST_START_MTTR_TARGET to a nonzero

value. If FAST_START_MTTR_TARGET is not specified, then MTTR advisory will be OFF.

When specified, FAST_START_MTTR_TARGET is overridden by LOG_CHECKPOINT_INTERVAL.

Note: The default value is 0. The range of values is 0 to 3600 seconds.

Question 14:

You execute the commands to configure settings in RMAN:

1Z0-063 exam questions 14

Then, you issue the following command to take a backup:

1Z0-063 exam questions 14-2

Which statement is true about the execution of these commands?

A. The backup terminates because the backup destination for the disk is not specified in the BACKUP command.

B. It backs up two copies of each of the data files to disk and media, and two copies of archived logs to media.

C. It backup up the data files and archived logs, making one copy of each data file and archived log on disk and media.

D. It backs up the data files and archived logs to media, making two copies of each data file and archived log.

Correct Answer: D


Question 15:

You are administering a multitenant container database (CDB) that contains multiple pluggable databases (PDBs). RMAN is connected to CDB$ROOT.

Examine the command:

RMAN> LIST FAILURE;

Which statement is true about this command?

A. It lists failures only for the CDB root database.

B. It lists failures for a PDB only when RMAN is connected to a recovery catalog.

C. It lists failures for the CDB and all the PDBs in this CDB.

D. It lists failures only if RMAN is connected to a PDB.

Correct Answer: A

In the current release, Data Recovery Advisor can only be used to diagnose and repair data corruptions in

non-CDBs and the root of a multitenant container database (CDB). Data Recovery Advisor is not

supported for pluggable databases (PDBs).

Note: You can run the LIST FAILURE command to show all known failures.
