• Question 13:

  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

  Correct Answer: CE

  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.

• Question 14:

  An airline is building a booking system for its premium and general customers. The goal is to ensure

  premium members are given higher access priority when user traffic is high.

  What configuration will achieve this goal?

  A. Configure a Work Manager for premium users with a Minimum Thread Constraint.

  B. Configure a Work Manager for premium users with a higher fair-share-request- class.

  C. Configure a Work Manager for premium users with a higher response-time- request-class.

  D. Configure a Work Manager general users with a Maximum Thread Constraint.

  E. Configure a Work Manager for premium users with a custom request-class.

  Correct Answer: B

  fair-share-request-class--Specifies the average thread-use time required to process requests. The default fair share value is 50.

  For example, assume that WebLogic Server is running two modules. The Work Manager for ModuleA specifies a fair-share-request-class of 80 and the Work Manager for ModuleB specifies a fair-sharerequest-class of 20. During a period of sufficient demand, with a steady stream of requests for each module such that the number requests exceed the number of threads, WebLogic Server will allocate 80% and 20% of the thread-usage time to ModuleA and ModuleB, respectively.

  * Example:

  lowpriority_workmanager low_priority 10

  highpriority_workmanager high_priority 100

  Note:

  * A request class expresses a scheduling guideline that WebLogic Server uses to allocate threads to requests. Request classes help ensure that high priority work is scheduled before less important work, even if the high priority work is submitted after the lower priority work.

  Incorrect:

  Not C: response-time-request-class--Specifies a response time goal in milliseconds. Response time goals

  are not applied to individual requests. Instead, WebLogic Server computes a tolerable waiting time for

  requests with that class by subtracting the observed average thread use time from the response time goal,

  and schedules requests so that the average wait for requests with the class is proportional to its tolerable

  waiting time.

  Not A, D: Not related to thread constraints.

  For example, assume that WebLogic Server is running two modules. The Work Manager for ModuleA

  specifies a fair-share-request-class of 80 and the Work Manager for ModuleB specifies a fair-sharerequest-class of 20.

• Question 15:

  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.

  Correct Answer: BCD

  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 Unitof-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

• Question 16:

  In a Java EE messaging application, one MDB is consuming a lot of memory at high traffic. What configuration should you use to prevent possible out-of-memory error at high traffic and at the same time not losing messages?

  A. Configure a Work Manager for the MDB with a Maximum Thread Constraint.

  B. Configure a Work Manager for the MDB with a Minimum Thread Constraint.

  C. Configure a Work Manager for the MDB with a Maximum Thread Constraint and a Capacity Constraint.

  D. Configure a Work Manager for the MDB with a Minimum Thread Constraint and a Capacity Constraint.

  E. Configure a Work Manager for the MDB with both a Maximum Thread Constraint and Minimum Thread Constraint.

  Correct Answer: B

  Note: *

  * When to Use Work Managers

  Following are guildelines to help you determine when you might want to use Work Managers to customize

  thread management:

  / The default fair share is not sufficient.

  This usually ocurrs in situations where one application needs to be given higher priority over another.

  / A response time goal is required.

  / A minimum thread constraint needs to be specified to avoid server deadlock

• Question 17:

  When a critical error occurs, which module in Enterprise Manager will automatically collect diagnostics data from WebLogic Server?

  A. Reports

  B. Compliance

  C. Support Workbench

  D. Asset Discovery

  E. visual creation of JDBC DataSource object to Oracle RAC

  Correct Answer: C

  Support Workbench is a feature where, on identification of a problem, targeted diagnostics data is dumped in a well-known format and location, for further analysis by administrators, Oracle Support and development. In case of Support Workbench for FMW, this feature works for Weblogic Server Targets.

• Question 18:

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

  A. HTTP

  B. JNI

  C. JNDI

  D. T3

  E. LDAP

  Correct Answer: C

  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 19:
