components by setting environment variables or by issuing crsctl debug commands using

the following syntax:

A. Configures parameters and adds new packages, where necessary

B. Validates hardware configuration for RAC

C. Performs cluster integrity checks

D. Installs pre-validated Oracle Database and Grid Infrastructure software

Answer: D

Explanation:

The Oracle-Validated rpm automatize the install of the numerous components required to

setup OCW and RAC on Linux, and execute most of the required OS configuration steps.

QUESTION NO:3

Which three items can be stored on the ACFS (Oracle ASM Cluster File System)?

A. Oracle Database Homes (shared home approach)

B. Any type of application-related configuration or log files

C. The Oracle Grid Infrastructure Home

D. Oracle Backup Sets (RMAN backup sets)

Correct Answer: ABD

Explanation

Explanation/Reference:

Oracle ASM Cluster File System (ACFS) is a general purpose cluster file system implemented as part of

ASM. It can be used to store almost anything, including the database executables. The only things that

should not be stored in ACFS are the Grid Infrastructure home and any Oracle files that can be directly

stored in Oracle ASM.

QUESTION NO:26

What value uniquely identifies an instance in a RAC database?

QUESTION NO:45

Which two options are checked by the Oracle Universal Installer, when you first install

Oracle Software on a system?

A. if the OFA-compliant path is available

B. oraInst.loc should exist

C. that the user running the installation has permissions to write to the designated path

D. that you are running OUI as a DBA user

Answer: A, B

Explanation:

A:

* When installing an OFA-compliant database using Oracle Universal Installer,

ORACLE_BASE is set to

/pm/app/oracle by default.

* All Oracle products on CD-ROM are OFA-compliant; that is, Oracle Universal Installer

places Oracle products in directory locations that follow OFA guidelines

B: Every Oracle software installation has an associated Central Inventory where the details

of all the Oracle products installed on a host are registered. The Central Inventory is

located in the directory that the inventory pointer file specifies. Each Oracle software

installation has its own Central Inventory pointer file that is unknown to another Oracle

software installation.

QUESTION NO:60

Which step will you have to perform on Windows to restore the OCR that you did not do

on Linux?

A. Identify existing backups with the -backup option

B. Use the Service Control Panel to stop services

C. Review the contents of the backup with the ocrdump command

D. Make sure that the restored OCR files are valid

Answer: B

Explanation:

See step 2) below.

Restoring the Oracle Cluster Registry on Windows-Based Systems

Use the following procedure to restore the OCR on Windows-based systems:

1. Identify the OCR backups using the ocrconfig -showbackup command. Review the

contents of the backup using ocrdump -backupfilefile_name where file_name is the name

of the backup file.

2. On all of the remaining nodes, disable the following OCR clients and stop them

using the Service Control Panel: OracleClusterVolumeService,OracleCSService,

OracleCRService, and the OracleEVMService.

3. Execute the restore by applying an OCR backup file that you identified in Step 1

with the ocrconfig -restore file name command. Make sure that the OCR devices that you

specify in the OCR configuration exist and that these OCR devices are valid.

4. Start all of the services that were stopped in step 2. Restart all of the nodes and

resume operations in cluster mode.

5. Run the following command to verify the OCR integrity where the -n all argument

retrieves a listing of all of the cluster nodes that are configured as part of your cluster:

cluvfy comp ocr -n all [-verbose] Note:

Restoring the Oracle Cluster Registry on UNIX-Based Systems

Use the following procedure to restore the OCR on UNIX-based systems:

1. Identify the OCR backups using the ocrconfig -showbackup command. Review the

contents of the backup using ocrdump -backupfilefile_name where file_name is the name

of the backup file.

2. Stop Oracle Clusterware on all the nodes in your Oracle RAC cluster by running

the following command as root:

3. # crsctl stop crs

Repeat this command on each node in your Oracle RAC cluster. Note:

Prior to running the crsctl start crs command in step 4, run the following command to

verify that all processes except init.cssd fatal are inactive:

ps -ef|grep cssd

4. Perform the restore by applying an OCR backup file that you identified in Step 1

using the following command where file_name is the name of the OCR that you want to

restore. Make sure that the OCR devices that you specify in the OCR configuration exist

and that these OCR devices are valid before running this command.

5. ocrconfig -restore file_name

6. Start Oracle Clusterware on all the nodes in your Oracle RAC cluster by running

the following command as root:

7. # crsctl start crs

Repeat this command on each node in your Oracle RAC cluster.

8. Run the following command to verify the OCR integrity where the -n all argument

retrieves a listing of all of the cluster nodes that are configured as part of your cluster:

9. cluvfy comp ocr -n all [-verbose]

QUESTION NO:15

What would be the total space required for Clusterware files when stopping them in the

ASM Diskgroup configured with NORMAL redundancy? (Assume each OCR and voting

Disk files uses 300 MB.)

A. 1.5 GB

B. 2.4 GB

C. 600 MB

D. 900 MB

Answer: A

Explanation:

When you use normal redundancy, Oracle Clusterware automatically maintains two copies

of the OCR file and three copies of the voting disk file.

QUESTION NO:22

Which two statements are true about starting and stopping all instances of a RAC

database simultaneously with a single command?

A. The user must be SYSDBA.

B. The user must be a member of the OSDBA group.

C. The user can use SQL* Plus from local node.

D. The user can use SRVCTL.

Answer: A, D

Explanation:

* Connecting as SYSOPER or SYSDBA enables you to perform privileged operations,

such as instance startup and shutdown.

* When you use SRVCTL to perform configuration operations on your cluster,

SRVCTL stores configuration data in the Oracle Cluster Registry (OCR). SRVCTL

performs other operations, such as starting and stopping instances, by calling SQL*Plus on

each node.

QUESTION NO:55

You are running ASMCMD in a non Interactive mode. Which statement is correct?

A. After the specified command has run, you are returned to the ASMCMD prompt.

B. You cannot run scripts in non Interactive mode ASMCMD

C. You can have arguments when running ASMCMD in non-interactive mode

D. You always run ASMCMD from the ASM home directory when running in non-

interactive mode

Answer: A, C

Explanation:

In noninteractive mode, you run a single ASMCMD command by including the

command and command options on the command line when invoking ASMCMD.

ASMCMD runs the command, generates output if any, and then exits.

Incorrect:

Not B: The noninteractive mode is especially useful for running scripts.
