Oracle 1Z0-048 valid study dumps : Oracle Database 10g R2: Administering RAC

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

The following query shows four MEMBER disks and three CANDIDATE disks.
SQL> select name, header_status, path from v$asm_disk;
NAME HEADER STATUS PATH
CANDIDATE /dev/rdsk/diska5
CANDIDATE /dev/rdsk/diska6
CANDIDATE /dev/rdsk/diska7
DISK01 MEMBER /dev/rdsk/diska1
DISK02 MEMBER /dev/rdsk/diska2
DISK03 MEMBER /dev/rdsk/diska3
DISK04 MEMBER /dev/rdsk/diska4
7 rows selected.
Using SQLPIus you want to add /dev/rdsk/diska5 and /dev/rdsk/diska6 to diskgroup DGROUP1
DGROUP1 is currently mounted.
Pick the statement that would fail to add diska5 and diska6.

• A. ALTER DISKGROUP dgroupl ADD DISK '/dev/rdsk/diska[56]';
• B. ALTER DISKGROUP dgroupl ADD DISK
  '/dev/rdsk/diska5',
  '/dev/rdsk/diska6';
• C. ALTER DISKGROUP dgroupl ADD DISK '/dev/rdsk/disk*5', '/dev/rdsk/disk*6';
• D. ALTER DISKGROUP dgroupl ADD DISK
  '/dev/rdsk/diska5' name disk05,
  '/dev/rdsk/diska6' name disk06;
• E. ALTER DISKGROUP dgroupl ADD DISK '/dev/rdsk/diska*';

You are migrating a single-instance Oracle database to RAC. The data files and Flash Recovery Area would be migrated to ASM using the RMAN commands BACKUP AS COPY DATABASE and BACKUP RECOVERY AREA, and stored in an ASM diskgroups called +DB_DG and +FR_DG. The DB_CREATE_FILE_DEST parameter would be set to +DB_DG and the DB_RECOVERY_FILE_DEST parameter would be set to +FR_DG.
What are the three best options for the location of your archivelogs so that they may be used properly for recovery without DBA intervention? (Choose three.)

• A. Cluster File System with each instance writing to a separate location as long as they are in directories under the same mount point.
• B. ASM diskgroup +DB_DG as specified for the Database Area provided that the ASM diskgroup is mounted on all ASM instances.
• C. Local File System with each instance writing to a local location provided that NFS read mount points are created to all other nodes with instances of the database.
• D. ASM diskgroup +FR_DG as specified for the Flash Recovery Area provided that the ASM diskgroup is mounted on all ASM instances.
• E. Local File System with each instance writing to a local location provided that the path names are identical on all nodes.
• F. Cluster File System with each instance writing to a shared location.

View the Exhibit and examine an installation step of Oracle Enterprise Manager Grid Control 10gR2 to manage your RAC installation. You entered the host name but you are not sure about the port number. Thefollowing is the list of port numbers from the host ed-otraclin17b.us.oracle.com:

• A. 4889
• B. 1158
• C. 1521
• D. 5561
• E. 3938

You have a three-tier architecture for your application, which uses an Oracle RAC database and a middle tier that uses Oracle Application Server with Java programming, using JDBC as the standard. There are three RAC services defined, and four instances in the database are using ASM as the cluster file system. Connection pools are also used. Which three features of Fast Application Notification would be beneficial in your environment, and which choices for your application would you recommend? (Choose three.)

• A. Load Balancing Advisory FAN events to control ASM I/O workload
• B. Load Balancing Advisory FAN events to control workload per instance for each service
• C. JDBC Implicit Connection Cache
• D. the App Server Up and Down FAN event notifications
• E. ODP.Net connection pool
• F. the continuous availability of services due to FAN events
