Question 1:

Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and

ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp.

A user issues a query on a table on one of the PDBs and receives the following error:

ERROR at line 1:

ORA-01565: error in identifying file `/u01/app/oracle/oradata/CDB1/temp01.tmp\’

ORA-27037: unable to obtain file status

Identify two ways to rectify the error. (Choose two.)

A. Add a new temp file to the temporary tablespace and drop the temp file that produced the error.

B. Shut down the database instance, and restore the temp01.tmp file from the backup, and then restart the database.

C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.

D. Shut down the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.

E. Shut down the database instance and then restart the CDB and PDBs.

Correct Answer: AE


Because temp files cannot be backed up and because no redo is ever generated for them, RMAN never restores or recovers temp files. RMAN does track the names of temp files, but only so that it can automatically re-create them when needed.


If you use RMAN in a Data Guard environment, then RMAN transparently converts primary control files to standby control files and vice versa. RMAN automatically updates file names for data files, online redo logs, standby redo logs, and temp files when you issue RESTORE and RECOVER.

Question 2:

Examine the following commands for redefining a table with Virtual Private Database (VPD) policies:

Free 1Z0-060 Exam Dumps Questions 2

Which two statements are true about redefining the table? (Choose two.)

A. All the triggers for the table are disabled without changing any of the column names or column types in the table.

B. The primary key constraint on the EMPLOYEES table is disabled during redefinition.

C. VPD policies are copied from the original table to the new table during online redefinition.

D. You must copy the VPD policies manually from the original table to the new table during online redefinition.

Correct Answer: AC

The triggers cloned to the interim table are disabled until the redefinition is completed. Once the redefinition is complete, all cloned objects are renamed to the original names used by the objects they were cloned from.


Question 3:

Which two statements are true about the use of the procedures listed in the v$sysaux_occupants.move_procedure column? (Choose two.)

A. The procedures may be used for some components to relocate component data to the SYSAUX tablespace from its current tablespace.

B. The procedures may be used for some components to relocate component data from the SYSAUX tablespace to another tablespace.

C. All the components may be moved into the SYSAUX tablespace.

D. All the components may be moved from the SYSAUX tablespace.

Correct Answer: AB


Question 4:

Which statement is true about Oracle Net Listener?

A. It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.

B. A single listener can service only one database instance and multiple remote client connections.

C. Service registration with the listener is performed by the listener registration process (LREG) process of each database instance.

D. The listener. or configuration file must be configured with one or more listening protocol addresses to allow remote users to connect to a database instance.

E. The listener. ora configuration file must be located in the ORACLE_HOME/network/admin directory.

Correct Answer: C

Question 5:

A. Oracle Data Pump

B. Oracle Recovery Manager (RMAN)

C. Oracle Label Security

D. Oracle Database Vault

E. Oracle Real Application Security

Correct Answer: B

Question 7:

Your multitenant container (CDB) containing three pluggable databases (PDBs) is running in ARCHIVELOG mode. You find that the SYSAUX tablespace is corrupted in the root container.

The steps to recover the tablespace are as follows:

1. Mount the CDB.

2. Close all the PDBs.

3. Open the database.

4. Apply the archive redo logs.

5. Restore the data file.

6. Take the SYSAUX tablespace offline.

7. Place the SYSAUX tablespace online.

8. Open all the PDBs with RESETLOGS.

9. Open the database with RESETLOGS.

10. Execute the command SHUTDOWN ABORT.

Which option identifies the correct sequence to recover the SYSAUX tablespace?

A. 6, 5, 4, 7

B. 10, 1, 2, 5, 8

C. 10, 1, 2, 5, 4, 9, 8

D. 10, 1, 5, 8, 10

Correct Answer: A







While evaluating the 12c beta3 I was not able to recover while testing “all pdb files lost”.

Cannot close the pdb as the system data file was missing…

So the only option to recover was:

Shutdown cdb (10)

startup mount; (1)

restore pluggable database

recover pluggable database

alter database open;

alter pluggable database name open;

Oracle support says: You should be able to close the pdb and restore/recover the system tablespace of



Inconsistent backups are usually created by taking online database backups. You can also make an

inconsistent backup by backing up data files while a database is closed, either:

/ Immediately after the crash of an Oracle instance (or, in an Oracle RAC configuration, all instances) / After shutting down the database using SHUTDOWN ABORT

Inconsistent backups are only useful if the database is in ARCHIVELOG mode and all archived redo logs are created since the backup is available.

* Open the database with the RESETLOGS option after finishing recovery: SQL> ALTER DATABASE OPEN RESETLOGS;

Question 8:

Which three are direct benefits of the multiprocess, multithreaded architecture of Oracle Database 12c when it is enabled?

A. Reduced logical I/O

B. Reduced virtual memory utilization

C. Improved parallel Execution performance

D. Improved Serial Execution performance

E. Reduced physical I/O

F. Reduced CPU utilization

Correct Answer: BCF

* Multiprocess and Multithreaded Oracle Database Systems

Multiprocess Oracle Database (also called multiuser Oracle Database) uses several processes to run different parts of the Oracle Database code and additional Oracle processes for the users–either one process for each connected user or one or more processes shared by multiple users.

Most databases are multiuser because a primary advantage of a database is managing data needed by multiple users simultaneously.

Each process in a database instance performs a specific job. By dividing the work of the database and applications into several processes, multiple users and applications can connect to an instance simultaneously while the system gives a good performance.

* In previous releases, Oracle processes did not run as threads on UNIX and Linux systems. Starting in Oracle Database 12c, the multithreaded Oracle Database model enables Oracle processes to execute as operating system threads in separate address spaces.

Question 9:

In order to exploit some new storage tiers that have been provisioned by a storage administrator, the partitions of a large heap table must be moved to other tablespaces in your Oracle 12c database.

Both local and global partitioned B-tree Indexes are defined in the table.

A high volume of transactions access the table during the day and a medium volume of transactions access it at night and during weekends.

Minimal disruption to availability is required.

Which three statements are true about this requirement? (Choose three.)

A. The partitions can be moved online to new tablespaces.

B. Global indexes must be rebuilt manually after moving the partitions.

C. The partitions can be compressed in the same tablespaces.

D. The partitions can be compressed in the new tablespaces.

E. Local indexes must be rebuilt manually after moving the partitions.

Correct Answer: ACD

A: You can create and rebuild indexes online. Therefore, you can update base tables at the same time you are building or rebuilding indexes on that table. You can perform DML operations while the index build is taking place, but DDL operations are not allowed. Parallel execution is not supported when creating or rebuilding an index online.

D: Moving (Rebuilding) Index-Organized Tables Because index-organized tables are primarily stored in a B-tree index, you can encounter fragmentation as a consequence of incremental updates. However, you can use the ALTER TABLE…MOVE statement to rebuild the index and reduce this fragmentation.

C: If a table can be compressed in the new tablespace, also it can be compressed in the same tablespace.

Incorrect Answers:

B, E: Local and Global indexes can be automatically rebuilt with UPDATE INDEXES when you move the



Question 10:

Which three are true about the large pool for an Oracle database instance that supports shared server connections?

A. Allocates memory for RMAN backup and restore operations

B. Allocates memory for shared and private SQL areas

C. Contains a cursor area for storing runtime information about cursors

D. Contains stack space

E. Contains a hash area performing hash joins of tables

Correct Answer: ABC

The large pool can provide large memory allocations for the following: / (B)UGA (User Global Area) for the shared server and the Oracle XA interface (used where transactions interact with multiple databases) /Message buffers used in the parallel execution of statements / (A) Buffers for Recovery Manager (RMAN) I/O slaves



large pool

Optional area in the SGA that provides large memory allocations for backup and restore operations, I/O

server processes, and session memory for the shared server and Oracle XA.


Oracle XA

An external interface that allows global transactions to be coordinated by a transaction manager other than

Oracle Database.



User global area. Session memory that stores session variables, such as logon information, and can also

contain the OLAP pool.


Configuring the Large Pool

Unlike the shared pool, the large pool does not have an LRU list (not D). Oracle Database does not

attempt to age objects out of the large pool. Consider configuring a large pool if the database instance

uses any of the following Oracle Database features:


Shared server

In a shared server architecture, the session memory for each client process is included in the shared pool.


Parallel query

The parallel query uses shared pool memory to cache parallel execution message buffers.


Recovery Manager

Recovery Manager (RMAN) uses the shared pool to cache I/O buffers during backup and restore

operations. For I/O server processes, backup, and restore operations, Oracle Database allocates buffers

that are a few hundred kilobytes in size.

Question 11:

You notice that the performance of your production 24/7 Oracle 12c database significantly degraded. Sometimes you are not able to connect to the instance because it hangs. You do not want to restart the database instance.

How can you detect the cause of the degraded performance?

A. Enable Memory Access Mode, which reads performance data from SGA.

B. Use emergency monitoring to fetch data directly from SGA analysis.

C. Run Automatic Database Diagnostic Monitor (ADDM) to fetch information from the latest Automatic Workload Repository (AWR) snapshots.

D. Use Active Session History (ASH) data and hang analysis in regular performance monitoring.

E. Run ADDM in diagnostic mode.

Correct Answer: B

Question 12:

You plan to use the In-Database Archiving feature of Oracle Database 12c, and store rows that are inactive for over three months, in Hybrid Columnar Compressed (HCC) format.

Which three storage options support the use of HCC? (Choose three.)

A. ASM disk groups with ASM disks consisting of Exadata Grid Disks.

B. ASM disk groups with ASM disks consisting of LUNs on any Storage Area Network array

C. ASM disk groups with ASM disks consisting of any zero-padded NFS-mounted files

D. Database files stored in ZFS and accessed using conventional NFS mounts.

E. Database files stored in ZFS and accessed using the Oracle Direct NFS feature

F. Database files stored in any file system and accessed using the Oracle Direct NFS feature

G. ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays

Correct Answer: AEG

HCC requires the use of Oracle Storage. Exadata (A), Pillar Axiom (G), or Sun ZFS Storage Appliance (ZFSSA).



Hybrid Columnar Compression, initially only available on Exadata, has been extended to support Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with Oracle Database Enterprise Edition and above


Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS). Oracle Direct NFS implements NFS V3 protocol within the Oracle database kernel itself. Oracle Direct NFS client overcomes many of the challenges associated with using NFS with the Oracle Database with simple configuration, better performance than traditional NFS clients, and offers consistent configuration across platforms.

Question 13:

In your multitenant container database (CDB) containing pluggable databases (PDB), users complain about performance degradation.

How does a real-time Automatic Database Diagnostic Monitor (ADDM) check performance degradation and provide solutions?

A. It collects data from SGA and compares it with a preserved snapshot.

B. It collects data from SGA, analyzes it, and provides a report.

C. It collects data from SGA and compares it with the latest snapshot.

D. It collects data from both SGA and PGA, analyzes it, and provides a report.

Correct Answer: B



The multitenant architecture enables an Oracle database to function as a multitenant container database (CDB) that includes zero, one, or many customer-created pluggable databases (PDBs). A PDB is a portable collection of schemas, schema objects, and non schema objects that appears to an Oracle Net client as a non-CDB. All Oracle databases before Oracle Database 12c were non-CDBs.


The System Global Area (SGA) is a group of shared memory areas that are dedicated to an Oracle “instance” (an instance is your database programs and RAM).


The PGA (Program or Process Global Area) is a memory area (RAM) that stores data and control information for a single process.

Question 14:

The tnsnames. ora file has an entry for the service alias ORCL as follows:

Free 1Z0-060 Exam Dumps Questions 14

The TNSPING command executes successfully when tested with ORCL; however, from the same OS user session, you are not able to connect to the database instance with the following command:

SQL > CONNECT scott/[email protected]

What could be the reason for this?

A. The listener is not running on the database node.

B. The TNS_ADMIN environment variable is set to the wrong value.

C. The database service is not registered with the listener.

D. The DEFAULT_DOMAIN parameter is set to the wrong value in the sqlnet.ora file.

E. The listener is running on a different port.

Correct Answer: C

Service registration enables the listener to determine whether a database service and its service handlers are available. A service handler is a dedicated server process or dispatcher that acts as a connection point to a database. During registration, the LREG process provides the listener with the instance name, database service names, and the type and addresses of service handlers. This information enables the listener to start a service handler when a client request arrives.

Question 15:

Examine the following steps of privilege analysis for checking and revoking excessive, unused privileges granted to users:

1. Create a policy to capture the privilege used by a user for privilege analysis.

2. Generate a report with the data captured for a specified privilege capture.

3. Start analyzing the data captured by the policy.

4. Revoke unused privileges.

5. Compare the used and unused privileges\’ lists.

6. Stop analyzing the data.

Identify the correct sequence of steps.

A. 1, 3, 5, 6, 2, 4

B. 1, 3, 6, 2, 5, 4

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

D. 1, 3, 2, 5, 6, 4

E. 1, 3, 5, 2, 6, 4

Correct Answer: B

1. Create a policy to capture the privilege used by a user for privilege analysis.

3. Start analyzing the data captured by the policy.

6. Stop analyzing the data.

2. Generate a report with the data captured for a specified privilege capture.

5. Compare the used and unused privileges\’ lists.

4. Revoke unused privileges.
