Question No: 22

Which two statements are true about starting and stopping all instances of a RAC database simultaneously with a single command?

  1. The user must be SYSDBA.

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

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

  4. 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.

  • Reference: Overview of Administering Oracle Real Application Clusters with SQL*Plus

    Question No: 23

    Identify three valid storage options for the OCR and voting disk for it new installation of Infrastructure 11g Release 2.

    1. A certified Cluster File System (CFS)

    2. A certified Network File System (NFS)

    3. ASM Cluster File System (ACFS)

    4. Automatic Storage Management (ASM)

    5. Shared disk slices (block or raw devices)

    Answer: B,C,D Explanation:

    B: Network attached storage (NAS) systems use a network file system (NFS) to access data. You can store Oracle RAC data files and recovery files on a supported NAS server using the Oracle Direct NFS client.

    C: Oracle Automatic Storage Management Cluster File System (Oracle ACFS) provides a general purpose file system. You can place the Oracle home for an Oracle Database 11g release 2 (11.2) database on Oracle ACFS, but you cannot place Oracle data files or Oracle Clusterware files on Oracle ACFS.

    D: Oracle recommends that you choose Oracle ASM as the shared storage option for the database data files and recovery files.

    Question No: 24

    In the end of the database creation process using DBCA which two options can you choose from?

    1. Create database

    2. Generate database creation scripts

    3. Initialize the database instance

    4. Configure the database initialization parameters such as memory target, character set, etc.

    Answer: A,C

    Explanation: Database Creation Options

    Check any of the following options for creating the database:

    • Create Database-Check to create your database at this time.

    • Save as a Database Template-Check to save the database definition as a template to use at another time.

    • Generate Database Creation Scripts-Check to generate a SQL database creation script that you can run at a later time.

      Question No: 25

      The Oracle Cluster Health Monitor can#39;t .

      1. Detect and analyze OS and duster resource for problems in Oracle Clusterware and RAC cluster

      2. Track OS resource consumption at each node, process, and device level continuously

      3. Be installed on Windows Server 20O3 SP1

      4. Collect and analyze the cluster-wide data

      Answer: C Explanation: Incorrect:

      Oracle Cluster Health Monitor is designed to detect and analyze operating system (OS) and cluster resource related degradation and failures in order to bring more explanatory power to many issues that occur in clusters where Oracle Clusterware and Oracle RAC are running such as node eviction. It continuously tracks the OS resource consumption at each node, process, and device level. It collects and analyzes this cluster-wide data. In real time mode, when thresholds are hit, an alert is shown to the operator. For root cause analysis, historical data can be replayed to understand what was happening at the time of failure.

      Question No: 26

      What value uniquely identifies an instance in a RAC database?

      1. Location name

      2. Node hostname

      3. Listener and port

      4. SID

      5. VIP

      Answer: D

      Explanation: The Oracle SID uniquely identifies the Oracle RAC database instance on the node where the instance is running.

      Question No: 27

      You are preparing the storage for Oracle ASM, which two statements are correct?

      1. You must create an ASMOWNER operating system user.

      2. You must choose a RAID stripe size that is a power of 2 and greater than the ASM allocation unit.

      3. Oracle ASMLIB is not a prerequisite to configure ASM.

      4. You must change user and group ownership of devices to oracle:dba.

      Answer: C,D Explanation: C:

    • ASMLib is an optional support library for the Automatic Storage Management feature of the Oracle Database.

    • Automatic Storage Management (ASM) simplifies administration of Oracle related files by allowing the administrator to reference disk groups rather than individual disks and files, which ASM manages internally. On Linux, ASM is capable of referencing disks as raw devices or by using the ASMLib software.

      D: Setting the ownership to oracle:dba is one example that corresponds to the default settings.

      Incorrect: Not B:

    • It is recomended that the hardware RAID stripe size be configured as a power of 2 and less than or equal to the size of the ASM allocation unit.

    • Choose a hardware RAID stripe size that is a power of 2 and less than or equal to the size of the Oracle ASM allocation unit.

      Question No: 28

      Under which account(s) can the Oracle Clusterware processes run for the Linux platform?

      1. only the root account

      2. only the Grid Infrastructure owner account

      3. only the database software owner account

      4. some under the Grid Infrastructure owner account and some under the root account

      5. some under the database software owner account and some under the root account

      Answer: A Explanation:

      Because Oracle Clusterware works closely with the operating system, system administrator access is required for some of the installation tasks. In addition, some of the Oracle Clusterware processes must run as the system administrator, which is generally the root user on Linux and UNIX systems and the LocalSystem account on Windows systems.

      Question No: 29

      Which of these is not recommended as the basis for an ASM disk in a shared storage configuration?

      1. Raw disk partition

      2. NFS file

      3. Raw logical volumes

      4. iSCSI targets

      Answer: A

      Explanation: * Block or raw devices are not supported by Oracle Universal Installer (OUI) or Database Configuration Assistant (DBCA). However, manually configured raw or block devices are supported by Oracle, but not recommended.

    • Shared disk access requires some sort of networked storage

      • iSCSI (not D)

      • Fibre Channel/SCSI

      • NFS (not B)

    • A logical volume is supported in less complicated configurations where a logical volume is mapped to a LUN, or a logical volume uses disks or raw partitions.

      Question No: 30

      Which two actions do you need to take in order to start up Oracle Grid Infrastructure automatically on boot?

      1. If Oracle Grid Infrastructure was disabled on a node, use “crsctl enable crs” to enable the automatic startup.

      2. Add the daemons to the system startup list.

      3. Nothing. By default, Oracle Grid Infrastructure is set up to start automatically on server boot.

      4. You must start clusterware daemons with individual commands in a batch file.

      Answer: A,C

      Explanation: We can use crsctl commands as follows to enable and disable the startup of the Oracle Clusterware daemons. Run the following command to enable startup for all of the Oracle Clusterware daemons:

      crsctl enable crs

      Run the following command to disable the startup of all of the Oracle Clusterware daemons:

      crsctl disable crs
