Oracle 1Z0-593 Online Questions & Answers

• Question 71:

  What should be the default software location for Oracle Clusterware?

  A. The same directory as the Oracle Database home
  B. Using Oracle RAC 11g Release 1, the Oracle Grid Infrastructure Home
  C. Using Oracle RAC 11g Release 2, the Oracle Grid Infrastructure Home
  D. The root file system
  A. The same directory as the Oracle Database home

  ---

  *

  Oracle Clusterware is installed as part of Oracle Database 11g. OUI installs Oracle Clusterware into a directory structure that is referred to as CRS_home. This home is separate from the home directories of other Oracle software products installed on the same server.

  *

  The Oracle RAC database software is installed from the same Oracle Database 11g installation media. By default, the standard Oracle Database 11g software installation process installs the Oracle RAC option when OUI recognizes that you are performing the installation on a cluster. OUI installs Oracle RAC into a directory structure that is referred to as Oracle_home. This home is separate from the home directories of other Oracle software products installed on the same server.

• Question 72:

  Which two directories are used during the installation of Grid Infrastructure and Oracle Database (with the RAC option)?

  A. ORACLE_HOME
  B. C:\ORACLE
  C. Grid Infrastructure Oracle Home
  D. ORACLE_GRID
  A. ORACLE_HOME
  D. ORACLE_GRID

  ---

  A: The Oracle RAC database software is installed from the same Oracle Database 11g installation media. By default, the standard Oracle Database 11g software installation process installs the Oracle RAC option when OUI recognizes that

  you are performing the installation on a cluster. OUI installs Oracle RAC into a directory structure that is referred to as Oracle_home. This home is separate from the home directories of other Oracle software products installed on the same

  server.

• Question 73:

  Which statement regarding the node VIPs is incorrect?

  A. Should register the hostnames for the VIP with a DNS, if available
  B. DNS name should be resolvable from any server node
  C. DNS name must be resolvable from any client
  D. VIP address should be in use at the time of installation
  D. VIP address should be in use at the time of installation

  ---

  During installation of the Oracle Grid Infrastructure for a cluster, a listener is created for each of the SCAN addresses. Clients that access the Oracle RAC database should use the SCAN or SCAN address, not the VIP name or address.

  Incorrect:

  Not A: The VIPs should be registered in the DNS.

  Not C: Advantage of Virtual IP deployment in Oracle RAC:

  Using VIP configuration, client can be able to get connection fast even fail over of connection request to node. Because vip automatically assign to another surviving node faster and it can't wait for TNS timeout old fashion.

• Question 74:

  Which two actions do you need to take in Oracle Grid Infrastructure 11g Release 2 to enable debugging for the resource ora.docrac.vip?

  A. Make sure you are logged in as a privileged user.
  B. crsctl debug res ora.docrac1.vip:1
  C. crsctl set log res ora.docrac1.vip:1
  D. crsctl debug log res ora.docrac1.vip:0
  A. Make sure you are logged in as a privileged user.
  C. crsctl set log res ora.docrac1.vip:1

  ---

  A: You can use crsctl commands as the root user to enable dynamic debugging for the Oracle Clusterware Cluster Ready Services (CRS), Oracle Cluster Registry (OCR), Cluster Synchronization Services (CSS), and the Event Manager (EVM).

  C: You can enable debugging for the CRS, OCR, CSS, and EVM modules and their components by setting environment variables or by issuing crsctl debug commands using the following syntax: crsctl debug log module_name component:debugging_level Reference: Oracle Clusterware Administration and Deployment Guide, Component Level Debugging

• Question 75:

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

  A. Raw disk partition
  B. NFS file
  C. Raw logical volumes
  D. iSCSI targets
  A. Raw disk partition

  ---

  *

  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 76:

  You want to set full debugging for the communications and resource management components for the CRS module on nodes host01 and host03. How can you accomplish this?

  A. crsctl set log CRS "CRSCTL: 5, CRSCOMM: 5" nodelist host01, host03
  B. crsctl lsmodules crs set log CRSCTL: 5, CRSCOMM: 5 nodelist host01, host03
  C. srvctl set log m CRSCTL5, CRSCOMM 5 n host01, host03
  D. ocrconfig set log CRS "CRSCTL, CRSCOMM: 5" nodelist host 01, host03
  A. crsctl set log CRS "CRSCTL: 5, CRSCOMM: 5" nodelist host01, host03

  ---

  To set log levels for the CRSRTI and CRSCOMM components of the CRS module: $ crsctl set log crs "CRSRTI=1,CRSCOMM=2"

• Question 77:

  Which three utilities can be used for managing the OCR?

  A. OCRCHECK
  B. OCRDUMP
  C. CRSCTL
  D. OCRCMD
  E. SRVCTL
  F. OCRCONFIG
  C. CRSCTL
  E. SRVCTL
  F. OCRCONFIG

  ---

  C: You can use crsctl commands as the root user to enable dynamic debugging for Oracle Clusterware, the Event Manager (EVM), and the clusterware subcomponents. You can also dynamically change debugging levels using crsctl commands. Debugging information remains in the Oracle Cluster Registry (OCR) for use during the next startup.

  E: The Server Control (SRVCTL) utility is installed on each node by default. You can use SRVCTL to start and stop the database and instances, manage configuration information, and to move or remove instances and services. You can also use SRVCTL to add services. SRVCTL also manages configuration information.

  Some SRVCTL operations store configuration information in the Oracle Cluster Registry (OCR).

  F: Use the ocrconfig command to manage OCR. Using this utility you can import, export, add, delete, restore, overwrite, backup, repair, replace, move, upgrade, or downgrade OCR. Note:

  * Oracle Cluster Registry (OCR)

• Question 78:

  You want to set up your RAC-enabled Database software so that you have the ability to perform rolling software upgrades. Which configuration option must you use?

  A. At least five voting disks in the cluster
  B. At least five copies of the OCR
  C. Use a local home for files for software that will be upgraded
  D. With RAC, you can perform only rolling database and not-software upgrades.
  C. Use a local home for files for software that will be upgraded

  ---

  Change directory to the Oracle Clusterware home. As root, run the preupdate.sh script on the local node, and on all other nodes in the subset that you intend to upgrade. Use the following command syntax, where clusterware_home is the

  path to the existing Oracle Clusterware home, and installation_owner is the Oracle Clusterware installation owner:

  ./preupdate.sh -crshome clusterware_home -crsuser installation_owner

  Incorrect:

  Not D: Both rolling database and rolling clusterware upgrades are possible.

• Question 79:

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

  A. You must create an ASMOWNER operating system user.
  B. You must choose a RAID stripe size that is a power of 2 and greater than the ASM allocation unit.
  C. Oracle ASMLIB is not a prerequisite to configure ASM.
  D. You must change user and group ownership of devices to oracle:dba.
  C. Oracle ASMLIB is not a prerequisite to configure ASM.
  D. You must change user and group ownership of devices to oracle:dba.

  ---

  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.
