NEW QUESTION 1
Oracle Clusterware manages an administrator-managed database service defined with the MANUAL management policy.
Which two statements are true?

  • A. The service must be manually restarted with SRVCTL every time the instance hosting the service fails.
  • B. Clusterware will monitor the service while it is active.
  • C. The service must be manually restarted with SRVCTL after restarting the Clusterware stack on the node hosting the service.
  • D. When manually started, the service will always start on one or more available instances rather than on their preferred instances.
  • E. The service must be manually started with SRVCTL after a planned restart of the instance hosting the service.

Answer: BE

Explanation: MANUAL: The database is never automatically restarted upon restart of the database host computer. A MANUAL setting does not prevent Oracle Clusterware from monitoring the database while it is running and restarting it if a failure occurs.
Note: To prevent Oracle Clusterware from restarting your Oracle RAC database when you restart your system, or to avoid restarting failed instances more than once, configure a policy to define the degree of control. There are two policies, automatic, which is the default, and manual.

  • A. The redundancy is lowered until the FG1 failgroup is restored and the disk group resynchronized.
  • B. New allocation units are mirrored in the FG2 failure group until FG1 is restored and the disk group resynchronized.
  • C. Transactions on database objects stored in tablespaces in the DGRP1 disk group fail.
  • D. New allocation units are not mirrored but changes to allocation units are tracked in the FG2 failure group.

Answer: BC

NEW QUESTION 4

NEW QUESTION 5
Which statement is true concerning the installation of an Oracle Grid Infrastructure 12c patchset and its status during the installation?

  • A. Some grid infrastructure patchsets may not be installed in a rolling fashion.
  • B. They can be applied in-place.
  • C. When performing rolling patches, crsctl query crs softwareversion always displays the lowest version of the software running anywhere in the cluster
  • D. When performing rolling patches, the VIPs for the node being patched are relocated to another node.

Answer: C

Explanation: To check the software versions on a single node or if the software version is the latest version installed in on a cluster.
You would use this option when you do the rolling upgrade.
$ crsctl query crs softwareversion [hostname]

NEW QUESTION 6
Which two statements are true regarding server-side connect-time load balancing for a RAC database when using SCAN listeners?

  • A. It is based on performance metrics provided by the database instances LREG processes.
  • B. LOCAL_LISTENER must be configured to point to the SCAN to enable server-side load balancing.
  • C. The service’s connection load balancing goal must be manually configured to enable server-side connect-time load balancing.
  • D. It’s enabled only when LOAD_BALANCE=YES is included in the TNS entry used by the client.
  • E. Server-side load balancing requires the REMOTE_LISTENER to point to the SCAN.

Answer: CE

Explanation: C: With server-side load balancing, the SCAN listener directs a connection request to the best instance currently providing the service, based on the -clbgoal and -rlbgoal settings for the service.
E: The SCAN is an essential part of Database configuration. So, by default, the REMOTE_LISTENER parameter is set to the SCAN, assuming that the Database is created using standard Oracle tools. This enables the instances to register with the SCAN Listeners as remote listeners to provide information on what services are being provided by the instance, the current load, and a recommendation on how many incoming connections should be directed to the instance.
Note: Single Client Access Name (SCAN) is an Oracle Real Application Clusters (Oracle RAC) feature that provides a single name for clients to access Oracle Databases running in a cluster.

NEW QUESTION 7
Which two statements are true about the Global Enqueue Service, Instance Locks, and global enqueues in Oracle 12c RAC?

  • A. In a RAC One Node database, there is no LMD0 process if only one instance is running.
  • B. Global Enqueues and Instance Locks replace mutexes completely in RAC database instances.
  • C. In a RAC database, there is no LMD0 process if only one instance is running.
  • D. Global Enqueues and Instance Locks replace latches completely in RAC database instances.
  • E. Global Enqueues may have owners and waiters in the same instance.
  • F. Global Enqueues may have converters and waiters in the same instance.

Answer: AF

Explanation: F: A convert queue is a queue of locks that are waiting to be converted to particular mode, this is the process of changing a lock from one mode to another, even a NULL is a lock. A resource has a lock value block (LVB). The Global Resource Manager (GRM) keeps the lock information valid and correct across the cluster. Oracle 10g release 2 and beyond replaced some latch mechanisms with the mutex approach, claiming that they are faster and more efficient than traditional locking mechanisms.

NEW QUESTION 8
Which three statements are true about Quality of Service Management (QoS)?

  • A. A server-pool can be managed by QoS even if it does have database instances running on any server in the pool.
  • B. It can manage database services only if they are defined as UNIFORM services.
  • C. It requires Oracle Grid Infrastructure for a Cluster to be installed and Clusterware to be running.
  • D. It supports multiple databases assigned to the same server pool.
  • E. Databases managed by QoS can be administrator managed or policy managed.

Answer: BCD

Explanation: B: Database services should be created as UNIFORM services, meaning the service is offered by every available instance running in the specified server pool. If your application requires a SINGLETON service, then, to use Oracle Database QoS Management in management mode, the service must run in a server pool that has a maximum size of one. If you use a SINGLETON service in a server pool that has a maximum size greater than one, then Oracle Database QoS Management reports a configuration violation.
C: Initial QoS configuration includes:

NEW QUESTION 9

Which statement is true?

  • A. An SPFILE is created and contains parameter settings only for PROD1.
  • B. An SPFILE is created and contains parameter settings for all instances.
  • C. An SPFILE is created for each instance containing instance-specific parameter settings only.
  • D. An SPFILE is created for each instance and contains parameter settings for all instances.

Answer: C

NEW QUESTION 10
You must replace a failed disk that was dropped from a disk group.
You want the rebalance operation to occur with minimal performance impact.
Which two options exist to achieve this? (Choose two.)

  • A. Make sure that the ASM_POWER_LIMIT parameter is set to 1 before rebalancing the disk group.
  • B. Increase the value of the DISK_REPAIR_TIME attribute for the disk group.
  • C. Use the WAIT clause with the ALTER DISKGROUP command.
  • D. Decrease the value of the DISK_REPAIR_TIME attribute for the disk group.
  • E. Set the POWER clause to 1 in the ALTER DISKGROUP command.

Answer: AB

NEW QUESTION 11
Which two statements are true about Instance Locks in Oracle 12c RAC? (Choose two.)

  • A. They are used when an application uses the DBMS_LOCK package for UL lock types.
  • B. They are used to coordinate the next value for a sequence created with the CACHE and ORDBR clauses.
  • C. They are used to coordinate the next value for a sequence created with the NOCACHE and NOORDER clauses.
  • D. They are used to coordinate access across multiple library caches for the same stored procedure.
  • E. They are used to coordinate access across multiple library caches for anonymous PL/SQL execution.

Answer: BD

NEW QUESTION 12
Examine this query and output:
SQL> select order_flag, cache_size, session_flag, keep_value,
2 from user_sequences where sequence_name = ‘SEQ1’; O CACHE_SIZE S K
-- ------------------- -- -- Y 10 N N
Performance analysis revealed severe SQ enqueue contention on the SEQ1 sequence. The SEQ1 sequence is incremented from all instances equally and is frequently used. Which two statements should you execute to reduce SQ enqueue contention?

  • A. alter sequence seq1 cache 10000;
  • B. alter sequence seq1 order;
  • C. alter sequence seq1 noorder;
  • D. exec sys.dbms_shared_pool.keep (‘SEQ1’, ‘Q’)
  • E. alter sequence seq1 keep;

Answer: AC

Explanation: A: Increasing sequence caches improves instance affinity to index keys deriving their values from sequences. That technique may result in significant performance gains for multi-instance insert-intensive applications.
C: When creating sequences for a RAC environment, DBAs should use the noorder keyword to avoid an additional cause of SQ enqueue contention that is forced ordering of queued sequence values. In RAC, a best practice is to specify the “noordered” clause for a sequence. With a non-ordered sequence, a global lock not required by a node whenever you access the sequence.

NEW QUESTION 13
Which two statements are true about the UNDROP clause of the ALTER DISKGROUP statement?

  • A. It cancels pending drops of disks dropped using the DROP DISKGROUP command.
  • B. A disk cannot be undropped as a result of a drop diskgroup.
  • C. It automatically unmounts the disks after successfully undropping them.
  • D. It is not possible to cancel pending drops of disks dropped using the force option.

Answer: BD

Explanation: The UNDROP DISKS clause of the ALTER DISKGROUP statement cannot be used to restore disks that are being dropped as the result of a DROP DISKGROUP statement, or for disks that are being dropped using the FORCE clause.

The ACFS disk group has 10 GB free space and the file system is currently mounted. You execute this command to increase the volume size:
ASMCMD >volresize –G ACFS –s 3G VOL1 Which statement is true regarding the outcome?

  • A. It succeeds.
  • B. It fails because the file system must be unmounted before resizing.
  • C. It fails because resizing a volume containing an ACFS file system must be performed using ACFSUTIL.
  • D. It succeeds but the file system is automatically unmounted.
  • E. It fails because the –f option is not specified.

Answer: C

Explanation: If there is an Oracle ACFS file system on the volume, then you cannot resize the volume with the volresize command. You must use the acfsutil size command, which also resizes the volume and file system.

NEW QUESTION 18
Which two statements are true about resources defined by an administrator and registered with Oracle 12c Clusterware for high availability?

  • A. A policy-managed resource can be started manually using crsctl.
  • B. A policy-managed resource can be started manually using srvctl.
  • C. Resource dependencies are automatically set when using a policy-managed resource.
  • D. An administrator-managed resource can be started manually using crsctl.
  • E. An administrator-managed resource can be started manually using srvctl.
  • F. The action script is automatically set when using a policy-managed resource.

Answer: AE

Explanation: A: With policy-based management, administrators specify the server pool (excluding the Generic and Free pools) in which the servers run. For example, a database administrator uses SRVCTL to create a server pool for servers hosting a database or database service. A clusterware administrator uses CRSCTL to create server pools for non-database use, such as creating a server pool for servers hosting an application.
E: Administrator-managed resources refer to databases. You must use SRVCTL to create server pools that host Oracle databases. You must use CRSCTL to create server pools that host non-database resources such as middle tiers and applications.
