On a UNIX platform, which three processes are required to be running on all nodes before initiating a cluster database creation? (Choose three.)

• A. evmd.bin
• B. ocssd.bin
• C. crsd.bin
• D. racgmon.bin

View the Exhibit.
Users complain about the performance of an Oracle database-based application. You are requested to investigate. From Grid Control, you immediately infer that one of the cluster database instances is currently unavailable. You also notice that the host where the instance belongs was recently rebooted due to an unknown reason.
Using Grid Control, you restart the instance and performance rapidly improves. You want to determine the cause of the instance startup failure after the system reboot, and you check the resource profiles on both the database and ASM instances involved.
Why was the instance not started by CRS?

• A. The instance could not be started by CRS because this instance depends on an ASM instance, which has its autostart attribute set to a value, thereby preventing CRS from starting this ASM instance after a system reboot.
• B. The database instance's autostart attribute indicates that CRS should not restart it after system boot.
• C. The instance was started by CRS but due to multiple instance failures CRS disabled the database instance, thereby preventing further restarts.
• D. The instance was not started by CRS because its target state was set to "offline" before the system was rebooted.
• E. The instance was started by CRS after the system was rebooted, but someone stopped it from within SQL*Plus.

Your system administrator informs you that there are a number of unexpected system reboots occurring on one of your Oracle database clusters. The system administrator has no clue whether this is a hardware or system software issue or whether the Oracle Clusterware is causing these reboots. To determine the source of these unexpected reboots, the system administrator asks you how you can enable debugging on the Oracle Clusterware software components. Which two statements are true regarding Oracle Clusterware debugging? (Choose two.)

• A. You can enable Oracle Clusterware debugging dynamically.
• B. You enable Oracle Clusterware debugging using the SRVCTL command.
• C. You enable Oracle Clusterware debugging using the CRSCTL command as the root user.
• D. You enable Oracle Clusterware debugging using the CRSCTL command as the oracle user.
• E. You have to restart Oracle Clusterware after enabling debugging to activate it.

After a failed cluster database creation process, you realize that the contents of the OCR does not
match the current cluster configuration anymore. Before you started the database creation
process, you created a logical backup of the OCR, and now you want to use this logical backup to
bring the OCR contents in sync with the current cluster configuration.
Which commands would you use and in which order to accomplish this task?
1 OCRCONFIG -REPAIR (on the local cluster node only)
2 OCRCONFIG -REPAIR (on all cluster nodes)
3 OCRCONFIG -RESTORE <path name>
4 OCRCONFIG -IMPORT <path name>
5 CRSCTL STOP CRS (on the local cluster node only)
6 CRSCTL STOP CRS (on all cluster nodes)
7 OCRCONFIG -SHOWBACKUP
8 CRSCTL START CRS (on the local cluster node only)
9 CRSCTL START CRS (on all cluster nodes)

• A. 7,6,3,2,9.
• B. 7,6,3,9.
• C. 6,4,9.
• D. 5,3,8.
• E. 5,4,8.
• F. 6,3,9.
• G. 7,6,4,9.

You are preparing to create a RAC cluster. You review the RAC requirements for UNDO tablespaces. Which three are valid statements? (Choose three.

• A. If no UNDO tablespace is available when the instance starts, the instance stores undo records in the SYSTEM rollback segments.
• B. It is not necessary to assign a specific UNDO tablespace to a specific instance.
• C. You cannot assign a specific UNDO tablespace to a specific instance.
• D. ALTER DATABASE SET UNDO_TABLEPACE=undotbs3 SID='RDBD01'; is correct.
• E. ALTER SYSTEM SET UNDO_TABLESPACE=undotbs3 SID='RDBD01'; is correct.
