Question 1

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

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

All the triggers for the table are disabled without changing any of the column names or column types in the table.
The primary key constraint on the EMPLOYEES table is disabled during redefinition.
VPD policies are copied from the original table to the new table during online redefinition.
You must copy the VPD policies manually from the original table to the new table during online redefinition.

Correct answer: AC

Explanation:

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 they objects they were cloned from.

Question 3

Which statement is true about Oracle Net Listener?

It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.
A single listener can service only one database instance and multiple remote client connections.
Service registration with the listener is performed by the listener registration process (LREG) process of each database instance.
The listener.ora configuration file must be configured with one or more listening protocol addresses to allow remote users to connect to a database instance.
The listener.ora configuration file must be located in the ORACLE_HOME/network/admin directory.

Correct answer: C

Question 4

An Automatic Database Diagnostic Monitor (ADDM) finding in your production database reports that the shared pool is inadequately sized. You diagnose that this is due to the different kinds of workloads and this occurs only during peak hours. The following are the parameter settings for the database instance:

You want to balance the memory between the System Global Area (SGA) components depending on the workload.

Which option would solve this problem?

setting the PGA_AGGREGATE_TARGET parameter to 200M and the SGA_MAX_SIZE parameter to 400M
setting the MEMORY_TARGET and SGA_MAX_SIZE parameters to 400M
setting the SGA_TARGET parameter to 300M
setting the SGA_MAX_SIZE parameter to 400M

Correct answer: C

Question 5

Which Oracle Database component is audited by default if the unified Auditing option is enabled?

Oracle Data Pump
Oracle Recovery Manager (RMAN)
Oracle Label Security
Oracle Database Vault
Oracle Real Application Security

Correct answer: B

Question 6

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?

6, 5, 4, 7
10, 1, 2, 5, 8
10, 1, 2, 5, 4, 9, 8
10, 1, 5, 8, 10

Correct answer: A

Explanation:

RMAN> ALTER TABLESPACE sysaux OFFLINE IMMEDIATE; RMAN> RESTORE TABLESPACE sysaux; RMAN> RECOVER TABLESPACE sysaux; RMAN> ALTER TABLESPACE sysaux ONLINE; * Example:While evaluating the 12c beta3 I was not able to do the recover while testing “all pdb files lost”. Cannot close the pdb as the system datafile was missing… So 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 PDB.* 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 created since the backup are available. * Open the database with the RESETLOGS option after finishing recovery:SQL> ALTER DATABASE OPEN RESETLOGS;

RMAN> ALTER TABLESPACE sysaux OFFLINE IMMEDIATE;

RMAN> RESTORE TABLESPACE sysaux;

RMAN> RECOVER TABLESPACE sysaux;

RMAN> ALTER TABLESPACE sysaux ONLINE;

* Example:

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

Cannot close the pdb as the system datafile was missing…

So 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 PDB.

* 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 created since the backup are available.

* Open the database with the RESETLOGS option after finishing recovery:

SQL> ALTER DATABASE OPEN RESETLOGS;

Question 7

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

Reduced logical I/O
Reduced virtual memory utilization
Improved parallel Execution performance
Improved Serial Execution performance
Reduced physical I/O
Reduced CPU utilization

Correct answer: BCF

Explanation:

* 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 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 8

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 on 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.)

The partitions can be moved online to new tablespaces.
Global indexes must be rebuilt manually after moving the partitions.
The partitions can be compressed in the same tablespaces.
The partitions can be compressed in the new tablespaces.
Local indexes must be rebuilt manually after moving the partitions.

Correct answer: ACD

Explanation:

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 rebuild with UPDATE INDEXES when you move the table.References: http://www.oracle.com/technetwork/issue-archive/2014/14-may/o34dba-2193424.html

Question 9

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

Allocates memory for RMAN backup and restore operations
Allocates memory for shared and private SQL areas
Contains a cursor area for storing runtime information about cursors
Contains stack space
Contains a hash area performing hash joins of tables

Correct answer: ABC

Explanation:

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 Note:* 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. * UGA 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 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.

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

Note:

* 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.

* UGA

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

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 10

What are three purposes of the RMAN “FROM SERVICE” clause? (Choose three.)

to support PUSH-based active database duplication
to support synchronization of a standby database with the primary database in a Data Guard environment
to support active database duplication by taking image copies of the source database
to support file restoration over the network in a Data Guard environment
to support file recovery over the network in a Data Guard environment

Correct answer: BDE

Explanation:

* With a control file autobackup, RMAN can recover the database even if the current control file, recovery catalog, and server parameter file are inaccessible. * RMAN uses a recovery catalog to track filenames for all database files in a Data Guard environment. A recovery catalog is a database schema used by RMAN to store metadata about one or more Oracle databases. The catalog also records where the online redo logs, standby redo logs, tempfiles, archived redo logs, backup sets, and image copies are created.
