Oracle Database 10g R2: Administering RAC Sample Questions:

1. While creating a new service inside your ORCL database, you encounter a problem during the execution of the srvctl add service command. Because you are unable to explain the reason for this failure, you decide to log a service request in Oracle Metalink. You want to make this service request as complete as possible. You want to create a trace file from your problematic srvctl command execution so that Oracle Support has all possible information to quickly identify and resolve your problem. How do you create a Java-based tool trace file?

A) Set the SRVM_DEBUG environment variable to TRUE before you execute the srvctl command.
B) Set the SRVM_TRACE environment variable to TRUE before you execute the srvctl command.
C) Request extra information by adding the -d (debug) command-line flag at the srvctl command line.
D) Set the DEBUG environment variable to TRUE before you execute the srvctl command.
E) Request extra information by adding the -v (verbose) command-line flag at the srvctl command line.

2. Which three storage types are suitable as a flash recovery area for an Oracle 10g RAC database? (Choose three.)

A) Shared NFS directory
B) Local file system
C) Cluster file system
D) Raw volume
E) ASM disk group

3. Your storage administrator informs you about some disk corruption issues in the disk subsystem where your Oracle Cluster Registry (OCR) backups are located. Your storage administrator has resolved these corruption issues by applying a patch to the storage subsystem, but to be sure that the OCR backups are not affected by this problem the administrator wants you to check the integrity of the OCR backups. How would you do this?

A) You can check whether the OCR backups are not corrupted by using the OCRCHECK command.
B) You create a logical export from the OCR backups by using the OCRCONFIG command and analyze the export file for errors.
C) You create another physical backup of the OCR backups by using the OCRCONFIG command, and if this succeeds without errors you know that the OCR backups are not corrupted.
D) You dump the OCR backup contents into a text file by using the OCRDUMP command, and if that succeeds without errors you know that your OCR backups are not corrupted.
E) There is no easy way to check your OCR backups for corruptions.

4. Which two statements are true in a RAC environment? (Choose two.)

A) After you create a service using Database Configuration Assistant (DBCA), you need to start it with a separate command.
B) After you create a service using SRVCTL, you need to start it with a separate command.
C) After you create a service, you need to enable it for CRS to manage it.
D) When using DBCA to create a service, you do not need to add the corresponding TNS entry in your tnsnames.ora on the cluster nodes.
E) When using SRVCTL to create a service, you do not need to add the corresponding TNS entry in your tnsnames.ora.

5. After the cluster database has been successfully created, several postinstallation tasks should be completed. Identify three of them. (Choose three.)

A) Back up the root.sh script.
B) Create the ASM instance.
C) Initialize the cluster backup procedure.
D) Verify the Enterprise Manager/Oracle Cluster Registry configuration by running srvctl config database -d db_name.
E) Set up additional required user accounts.
