QUESTION NO: 1
The advantage of core tiles is that they allow you an opportunity to examine the cause of
problems, so that they can be resolved.
However, core files must be managed because they_____.

A. take up large amounts of disk space
B. make numerous entries into the /var/adm/wtmpx file
C. steal resources from the processor, slowing down system performance
D. fill up swap space; this will begin to slow the system due to swaps
E. fill up swap space; this will begin to slow the system due to paging

Answer: A

Explanation: Part of the job of cleaning up heavily loaded file systems involves locating and removing files that have not been used recently. You can locate unused files by using the ls or find commands.
Other ways to conserve disk space include emptying temporary directories such as the directories located in /var/tmp or /var/spool, and deleting core and crash dump files.
Note: Core files are generated when a process or application terminates abnormally. Core files are managed with the coreadm command.
For example, you can use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier to track problems byexamining the core files in a specific directory whenever a process or daemon terminates abnormally.

A. help prevent core dumps on program errors
B. help programs to execute more quickly by keeping to their own memory space
C. log any messages into the stack log
D. help make buffer-overflow attacks more difficult

Answer: D

Explanation: How to Disable Programs From Using Executable Stacks
Purpose: Prevent executable stack from overflowing.
You must be in the root role.

QUESTION NO: 1
When do you specify the type of interleaving for a grid disk?

A. When you create the cell disk
B. When you create the grid disk
C. Through ASM
D. When you create a tablespace

Answer: C

Explanation: Automatic Storage Management (ASM) is the storage management foundation of Exadata. ASM virtualizes the storage resources and provides the advanced volume management and file system capabilities of Exadata. Striping database files evenly across the available Exadata cells and disks results in uniform I/O load across all the storage hardware. The ability of ASM to perform non-intrusive resource allocation, and reallocation, is a key enabler of the shared grid storage capabilities of Exadata environments. And the ASM mirroring and failure group functionality provides much of the data protection and resiliency across the Exadata environment.
With ASM, data is mirrored across cells to ensure high availability in the event of cell failure.
http://www.pythian.com/news/17905/physical-disk-cell-disk-grid-disk-and-asm-disk-in-exadata/


QUESTION NO: 2
Why would you reduce the default disk_repair_time parameter?

A. To extend the availability of your ASM disk groups.
B. To reduce the need for high redundancy
C. To reduce the amount of data collected for a fast resynch
D. To increase performance of an Exadata Storage Server.

QUESTION NO: 1
Object Security controls access to Subject Areas, Tables, and Columns in OBIEE and can be implemented by using which method?

A. Single Sign-On (SSO)
B. Database Authentication
C. Business Logic Object Security
D. External Table Authentication
E. LDAP Authentication

Answer: C

Explanation: Object-level security controls the visibility to business logical objects based on a user's role. You can set up object-level security for metadata repository objects, such as subject areas and presentation folders, and for Web objects, such as dashboards and dashboard pages, which are defined in the Presentation Catalog.
1) Business logic object
This controls access to objects, such as:
* subject areas
* presentation tables
* presentation columns
For example, users in a particular department can view only the subject areas that belong to their department.
2) Web object security
This provides security for objects stored in the Web Catalog, such as dashboards, dashboard pages, folders, and reports. You can view only the objects for which you are authorized. For example, a mid-level manager may not be granted access to a dashboard containing summary information for an entire department.

QUESTION 1
You want to create procedures, functions and packages Which privilege do you need?
A. EXECUTE CODE object privilege
B. CREATE ANY CODE object privilege
C. CREATE PACKAGE system privilege
D. CREATE PROCEDURE system privilege
E. CREATE FUNCTION, CREATE PROCEDURE, CREATE PACKAGE system privileges

Answer: D

Explanation/Reference:
The privilege CREATE PROCEDURE gives the grantee the right to create procedures, functions, and packages within their schema. This privilege does not give the right to drop or alter the program constructs.
Incorrect Answers
A, B & C are not valid object or system privileges.


QUESTION 2
You have created a stored procedure DELETE_TEMP_TABLE that uses dynamic SQL to remove a table in your schema. You have granted the EXECUTE privilege to user A on this procedure. When user A executes the DELETE_TEMP_TABLE procedure, under whose privileges are the operations performed by default?
A. SYS privileges
B. Your privileges
C. Public privileges
D. User A's privileges
E. User A cannot execute your procedure that has dynamic SQL.

Answer: B

Explanation/Reference:
When you create a procedure, it will be executed under the privileges of the creator, unless the procedure has the following statement AUTHID CURRENT_USER. If you specify AUTHID CURRENT_USER, the privileges of the current user are checked at run time, and external references are resolved in the schema of the current user. Like this example
SQL> CREATE OR REPLACE PROCEDURE delete_temp_table(v_table varchar2)
2 AUTHID CURRENT_USER
3 IS
4 BEGIN
5 EXECUTE IMMEDIATE 'DROP TABLE '||V_TABLE;
6 END;
7 /
Procedure created.
If the procedure is create in this way then the EXECUTE IMMEDIATE statement will be execute under the privilege of the user who executes the procedure, but if we skip line 2 then the procedure will be executed under the privilege of the owner of the procedure.
Incorrect Answers
A: SYS privilege has nothing with is.
C: What is the public privileges? There is nothing called public privileges.
D: This will be true if the procedure contains the AUTHID CURRENT_USER.
E: There is no problem in having a dynamic SQL statement in Procedure.


QUESTION 3
When creating a function, in which section will you typically find the RETURN keyword?
A. HEADER only
B. DECLARATIVE
C. EXECUTABLE and HEADER
D. DECLARATIVE,EXECUTABLE and EXCEPTION HANDLING

QUESTION 1
Examine the following command used to perform incremental level 0 backup:

RMAN> BACKUP INCREMENTAL LEVEL 0 DATABASE;

To enable the block change tracking, after the incremental level 0 backup you issued the following command:

SQL> ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE '/mydir/
rman_change_track.f';

To perform incremental level 1 cumulative backup, you issued the following command:

RMAN> BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE;

Which two statements are true in the above situation? (Choose two.)

A. The block change tracking data will be used only from the next incremental 0 backup.
B. The incremental backup will use change tracking data for accomplishing the backup.
C. The incremental backup will not use change tracking data for accomplishing the backup.
D. The block track file will scan all the blocks and create bitmap for all the blocks backed up in the level 0
backup.

Answer: AC
Section: Backup, Recovery & Recovery Manager (RMAN)

Explanation/Reference:
Section: Backup, Recovery & Recovery Manager (RMAN)

http://www.pythian.com/documents/Pythian-oracle-block-change.pdf After enabling change tracking, the first level 0 incremental backup still has to scan the entire datafile, as the change tracking file does not yet reflect the status of the blocks. Subsequent incremental backup that use this level 0 as parent will take advantage of the change tracking file. When some a chunk needs to be marked dirty for the first time after incremental backup, version information in bitmap extent headers (X$KRCFBH) is initialized - XFLAGS is set to 2, CURR_VERCNT and CURR_VERTIME
filled from datafile descriptor. If file had no changes since last incremental backup - nothing is written to the bitmap. There is no difference in handling different backup levels. Version is created in the same way whether its level 0, level 1 or level 4 backup. By the way, it seems that Oracle 10g documentation officially mentions only support for levels 0 and 1. However, I checked incremental backup levels up to 4 and they do work (10.2.0.2). Oracle Press 1Z1-053 Exam Guide, Chapter 4: Creating RMAN Backups The first incremental level 0 backup reads every block in the datafile, and subsequent incremental level 1 backups use the block change tracking file. No reference to create bitmap found. http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm#i1032148

RMAN's change tracking feature for incremental backups improves incremental backup performance by recording changed blocks in each datafile in a change tracking file. If change tracking is enabled, RMAN uses the change tracking file to identify changed blocks for incremental backup, thus avoiding the need to scan every block in the datafile. Using change tracking in no way changes the commands used to pe form incremental backups, and the change tracking files themselves generally require little maintenance after initial configuration.



QUESTION 2
You want to use the automatic management of backup and recovery operations features for your database.

Which configuration must you set?
