Oracle 1Z0-599 Online Questions & Answers

• Question 71:

  A customer is developing a custom application that involves a multistep provisioning process for a new account. There is a custom Java client application that is generating multiple JMS messages as part of the process and sending them to the WebLogic tier where they are processed. Which three steps must you take to implement the solution to allow for scalability and parallel processing of multiple simultaneous provisioning requests while ensuring messages for an individual process are not delivered out of order?

  A. Update the client application that is creating the JMS messages to use Unit of Work.
  B. Configure a WebLogic Cluster for Distributed JMS.
  C. Update the client application that is creating the JMS messages to use Unit of Order.
  D. Enable XA Transactions on the JMS Connection Factory used by the client application.
  E. Enable Load Balancing on the JMS connection factory used by the client application.
  B. Configure a WebLogic Cluster for Distributed JMS.
  C. Update the client application that is creating the JMS messages to use Unit of Order.
  D. Enable XA Transactions on the JMS Connection Factory used by the client application.

  C: Message Unit-of-Order is a WebLogic Server value-added feature that enables a stand-alone message producer, or a group of producers acting as one, to group messages into a single unit with respect to the processing order. This single unit is called a Unit-of-Order and requires that all messages from that unit be processed sequentially in the order they were created.

  D Transactions required for parallel processing.

  Incorrect:

  A: Many applications need an even more restricted notion of a group than provided by the Message Unit- of-Order (UOO) feature. If this is the case for your applications, WebLogic JMS provides the Unit-of-Work (UOW) Message Groups, which allows applications to send JMS messages, identifying some of them as a group and allowing a JMS consumer to process them as such. For example, an JMS producer can designate a set of messages that need to be delivered to a single client without interruption, so that the messages can be processed as a unit. Further, the client will not be blocked waiting for the completion of one unit when there is another unit that is already complete.

  Note:

  * WebLogic JMS defines two default connection factories, which you can look up using the following JNDI names:

  weblogic.jms.ConnectionFactory

  weblogic.jms.XAConnectionFactory

  Reference: Using Message Unit-of-Order

• Question 72:

  Which technology does WebLogic Server use to look up a WebLogic JMS resource?

  A. HTTP
  B. JNI
  C. JNDI
  D. T3
  E. LDAP
  C. JNDI

  ---

  Using JNDI, a JMS client can obtain access to a JMS provider by first looking up a ConnectionFactory. The ConnectionFactory is used to create JMS connections, which can then be used for sending and receiving messages. Destination objects, which represent virtual channels (topics and queues) in JMS, are also obtained via JNDI and are used by the JMS client. The directory service can be configured by the system administrator to provide JMS administered objects so that the JMS clients don't need to use proprietary code to access a JMS provider.

  Note:

  * The Java Naming and Directory Interface (JNDI) is part of the Java platform, providing applications based on Java technology with a unified interface to multiple naming and directory services.

• Question 73:

  You want to migrate an application that was developed for OAS/OC4J to WebLogic. The application uses Oracle Streams Advanced Queuing (AQ). You configured a Foreign JMS Server and Data Source but you are not able to send messages to the AQ destination and see them reach the database. Which two things are missing in this configuration?

  A. nothing, there may be a network connection issue
  B. a Foreign JMS Connection Factory
  C. a JMS Bridge to map the JNDI of the Local JMS Destination to the remote AQ destination
  D. a mapping of the Foreign JMS Connection Factory to the Data Source where AQ is configured and installed.
  E. Oracle AQ Java EE Shared Libraries not deployed and referenced by your application
  C. a JMS Bridge to map the JNDI of the Local JMS Destination to the remote AQ destination
  E. Oracle AQ Java EE Shared Libraries not deployed and referenced by your application

  ---

  C:

  *

  A WebLogic Messaging Bridge communicates with the configured source and target bridge destinations. For each mapping of a source destination to a target destination, you must configure a messaging bridge instance. Each messaging bridge instance defines the source and target destination for the mapping, a message filtering selector, a QOS, transaction semantics, and various reconnection parameters.

  Note:

  *

  In your JMS Foreign Server configuration:

  / Specify oracle.jms.AQjmsInitialContextFactory as the JNDI Initial Context Factory. / Configure the JDBC data sources needed for your application environment.

  class files to specify deployment information, eliminating the need to create the ra.xml file manually.

• Question 76:

  Which new key architectural element introduced in WebLogic Server l2c should you take advantage of when designing Disaster Recovery Centers with active - passive mode?

  A. MAN Clusters, because they would allow you to synchronously replicate state in low latency networks
  B. WAN Clusters, because they would allow you to asynchronously replicate state in nonlow latency networks.
  C. Transaction Log in the database, because you could avoid synchronizing two replication technologies (database and file)
  D. Data Guard, because it is the most effective way to replicate a state across locations
  E. GoldenGate, because it is the most effective way to replicate a state across locations
  E. GoldenGate, because it is the most effective way to replicate a state across locations

  Oracle GoldenGate Oracle GoldenGate is Oracle's strategic product for data distribution and data integration. It is a highperformance software application that uses log-based bidirectional data replication for real- time capture, transformation, routing, and delivery of database transactions across heterogeneous systems.

  Note:

  *

  Oracle Active Data Guard Oracle Active Data Guard 11g is an option of Oracle Database Enterprise Edition that extends basic Data Guard functionality. It allows a physical standby database to be open as read-only while changes are applied to it from the primary database. This increases performance and return on investment by offloading ad-hoc queries, Web-based access, reporting, and backups from the primary database while also providing disaster protection.

  *

  Disaster recovery (DR) procedures ensure rapid recovery or continuation of a technology infrastructure after a natural or human-induced disaster. Oracle WebLogic Server 12c supports advanced disaster recovery and business continuity. Organizations can store transaction logs in an Oracle database instead of a file system, providing a highly available storage mechanism to improve the speed and reliability of disaster recovery operations. This permits them to utilize Oracle Active Data Guard or Oracle GoldenGate replication technology to move DR state information across data centers. Oracle's enhanced DR architecture enables more effective recovery scenarios. Support for Oracle Exalogic and Oracle Exadata engineered systems ensures tremendous scalability for IT operations of any size.

  *

  Oracle WebLogic Server 12c places transaction logs on the database tier to improve the speed, reliability and availability of disaster recovery operations.

  

• Question 77:

  What does the Fast Connection Failover feature of Active GridLink for RAC provide?

  A. instant notification of a RAC node failure so applications never have to retry a transaction that was sent to a node that failed during the transaction
  B. near-instant notification of the failure of a RAC node failure that minimizes the possibility connection to a failed node being provided to an application
  C. application level notification of a failed RAC node such that an application can retry a transaction if required
  D. faster failover for Multi Datasources
  E. guaranteed transaction high availability when interacting with an Oracle RAC Database
  B. near-instant notification of the failure of a RAC node failure that minimizes the possibility connection to a failed node being provided to an application

  ---

  *

  WebLogic Server supports Fast Connection Failover, a Oracle feature which provides an application independent method to implement RAC event notifications, such a detection and cleanup of invalid connections, load balancing of available connections, and work redistribution on active RAC instances.

  *

  A GridLink data source uses Fast Connection Failover and responds to Oracle RAC events using ONS. This ensures that the connection pool in the GridLink data source contains valid connections (including reserved connections) without the need to poll and test connections
