In informative level, we should be more efficient. In order to take the initiative, we need to have a strong ability to support the job search. And how to get the test Oracle certification in a short time, which determines enough qualification certificates to test our learning ability and application level. This may be a contradiction of the problem, we hope to be able to spend less time and energy to take into account the test Oracle certification, but the qualification examination of the learning process is very wasted energy, so how to achieve the balance? The 1Z0-045 exam prep: Oracle database 10g:new features for Oracle8i ocps can be done.

Efficient use of fragmentation time

The 1Z0-045 study guide to good meet user demand, will be a little bit of knowledge to separate memory, every day we have lots of fragments of time, such as waiting in line to take when you eat, or time in buses commute on the way by subway every day, don't look at the time, but when you add them together will be surprised to find a day we can make use of the time is so much debris. The 1Z0-045 exam prep: Oracle database 10g:new features for Oracle8i ocps can allow users to use the time of debris anytime and anywhere to study and make more reasonable arrangements for their study and life. Choosing our 1Z0-045 simulating materials is a good choice for you, and follow our step, just believe in yourself, you can do it perfectly!

Convenient app tools

In order to facilitate the wide variety of users' needs the 1Z0-045 study guide have developed three models with the highest application rate in the present - PDF, software and online. Online mode of another name is App of study materials, it is developed on the basis of a web browser, as long as the user terminals on the browser, can realize the application which has applied by the 1Z0-045 simulating materials of this learning model, users only need to open the App link, you can quickly open the learning content in real time in the ways of the study materials, can let users anytime, anywhere learning through our App, greatly improving the use value of our 1Z0-045 exam prep: Oracle database 10g:new features for Oracle8i ocps, but also provide mock exams, timed test and on-line correction function, achieve multi-terminal equipment of common learning.

Compact curriculum

The memory needs clues, but also the effective information is connected to the line, systematic study, in order to deepen the learner's impression, avoid the quick forgetting. Therefore, we can see that in the actual teaching process, how the course arrangement plays a crucial role in the teaching effect. The 1Z0-045 study guide in order to allow the user to form a complete system of knowledge structure, the qualification examination of test interpretation and supporting course practice organic reasonable arrangement together, the 1Z0-045 simulating materials let the user after learning the section of the new curriculum can through the way to solve the problem to consolidate, and each section between cohesion and is closely linked, for users who use the 1Z0-045 exam prep: Oracle database 10g:new features for Oracle8i ocps to build a knowledge of logical framework to create a good condition.

Oracle database 10g:new features for Oracle8i ocps Sample Questions:

1. Consider the following command to add a new disk group called "tdgroupA" with two failover groups:
CREATE DISKGROUP tdgroupA NORMAL REDUNDANCY FAILOVERGROUP control01 DISK
'/devices/A1',
'/devices/A2',
'/devices/A3'
FAILOVERGROUP control02 DISK
'/devices/B1',
'/devices/B2',
'/devices/B3';
The disk "/devices/A1" is currently a member disk of a disk group by name "tdgroup1".
Which task would be accomplished by the command?

A) A new disk group calledtdgroupA will be added with two failover groups and the /devices/A1 disk gets detached from the existing disk group tdgroup1 and attached to the new disk group tdgroupA disk group.
B) This command would result in an error because a disk group can have only one failover group.
C) A new disk group calledtdgroupA will be added with two failover groups and the /devices/A1 disk will be ignored for the new disk group because it is a member of an existing disk group tdgroup1.
D) This command would result in an error because the /devices/A1 disk is a member of another disk group tdgroup1.
E) A new disk group calledtdgroupA will be added with two failover groups and the /devices/A1 disk will get reattached to the new disk group without being detached from the existing one.

2. Which two statements regarding the Flashback Table feature are correct? (Choose two.)

A) Flashback Table operation acquires exclusive data manipulation language (DML) locks.
B) Flashback Table operation does not shrink the segments.
C) Flashback Table can be performed on system tables.
D) Flashback Table uses log mining to extract SQL_REDO and SQL_UNDO statements.

3. Which task would you perform to convert little-endian CLOB data to the big endian format while transporting from a database created in an earlier version of Oracle to an Oracle 10g database?

A) Transport the data after changing the character set of the target database to bigendian.
B) No action is required because Oracle RDBMS implicitly does the conversion in Oracle 10g database while accessing the data.
C) Transport the data after changing the character set to be anendian-independent format in the target database.
D) Use the CHANGE command of the RMAN utility.
E) Use the CONVERT command of the RMAN utility.

4. Immediately after adding a new disk to or removing an existing disk from an ASM instance, you find that the performance of the database goes down initially until the time the addition or removal process is completed, and then gradually becomes normal. Which two activities would you perform to maintain a consistent performance of the database while adding or removing disks? (Choose two.)

A) Increase the number of checkpoint processes.
B) Define the POWER option while adding or removing the disks.
C) Increase the number of slave database writer processes by setting up a higher value for DBWR_IO_SLAVES.
D) Increase the number of ARB processes by setting up a higher value for ASM_POWER_LIMIT.
E) Increase the number of DBWR processes by setting up a higher value for DB_WRITER_PROCESSES.

5. You explicitly specified the tablespace usage threshold values while creating a tablespace. You need to revert to the database-wide default tablespace usage threshold values for the tablespace. Which PL/SQL package would you use?

A) DBMS_STATS
B) DBMS_SPACE_ADMIN
C) DBMS_SPACE
D) DBMS_MONITOR
E) DBMS_ALERT
F) DBMS_SERVER_ALERT
