Oracle 1Z0-478 Online Questions & Answers

• Question 1:

  Which activity is used to invoke a human task from a BPEL process?

  A. Invoke
  B. Human task
  C. Task
  D. Invoke human task
  E. Start human task
  A. Invoke

  ---

  Note:

  *

  Activities are the building blocks of a BPEL process service component. Oracle BPEL Designer includes a set of activities that you drag into a BPEL process service component. You then double-click an activity to define its attributes

  (property values). Activities enable you to perform specific tasks within a BPEL process service component. For example, here are several key activities:

  / An assign activity enables you to manipulate data, such as copying the contents of one variable to another.

  / An invoke activity enables you to invoke a service (identified by its partner link) and specify an operation for this service to perform.

  / A receive activity waits for an asynchronous callback response message from a service.

  *

  Invoking a human task from a BPEL process is a two-step process:

  1.

  Creating a human task.

  2.

  Wiring and invoking the human task from BPEL.

• Question 2:

  Which two activities are typically performed during the service implementation and configuration phase of the SOA lifecycle?

  A. Capabilities are evaluated and prioritized based on business models and ROI.
  B. Oracle Enterprise Repository promotes services and harvested endpoints to the service registry.
  C. Developers find and reuse services to help them complete development.
  D. Developers use harvesting tools to submit their completed implementations to Oracle Enterprise Repository.
  C. Developers find and reuse services to help them complete development.
  D. Developers use harvesting tools to submit their completed implementations to Oracle Enterprise Repository.

  Implementation and Configuration

  As capabilities are funded, projects are established to implement the capability. SOA Suite developers working in JDeveloper can see and reuse services from the enterprise repository to complete their projects. Service Bus developers working in Eclipse can see and reuse services from the enterprise repository to complete their projects (C). Developers can also harvest their completed implementations directly to the Enterprise Repository (D). The Enterprise repository also supports VS .Net development.

• Question 3:

  You have modeled a composite with a one-way Mediator component that is exposed via an inbound file adapter service. How do you configure the inbound file adapter to read local files in ascending order of their lastModifiedTime?

  A. By setting the SingleThreadModel activationsSpec property to true and configuring the ListSorter activationSpec property to oracle.tip.adapter.file.inbound.listing.TimestampSorterAscending.
  B. By not making any configuration changes because, by default, the adapter reads input files in ascending order of their lastModifiedTime.
  C. By setting the ThreadCount activationSpec property to 0 and configuring the List Sorter activationSpec property to oracle.tip.adapter.file.inbound.listing.TimestampSorterDescending.
  D. By setting the ThreadCount activatioSpec property to 1 and configuring the ListSorter activationSpec property to oracle.tip.adapter.file.inbound.liting.TimestampSorterAscending.
  A. By setting the SingleThreadModel activationsSpec property to true and configuring the ListSorter activationSpec property to oracle.tip.adapter.file.inbound.listing.TimestampSorterAscending.

  When files must be processed by Oracle File and FTP Adapters in a particular order, you must configure the sorting parameters. For example, you can configure the sorting parameters for Oracle File and FTP Adapters to process files in

  ascending or descending order by time stamps.

  You must meet the following prerequisites for sorting scenarios of Oracle File and FTP Adapters:

  Use a synchronous operation

  Add the following property to the inbound JCA file:

  value="oracle.tip.adapter.file.inbound.listing.TimestampSorterAscending"/>

• Question 4:

  In your solution, a web service client needs to invoke a series of three web services in support of a single transaction. The third web service needs the identity of the original web service client.

  Which statement describes how the identity is made available by Oracle Web Services Manager (OWSM)?

  A. The transaction manager accesses an internal table that maintains credentials used to invoke each individual web service in the chain.
  B. Each web service in the chain does its own authentication so the third web service handles its own identity checking.
  C. OWSM sets the user in the Java Authentication and Authorization (JAAS) Subject when the first web service successfully authenticates, and the Java Subject is used by subsequent web services to access the identity.
  D. OWSM stores a SAML token from the first web service invocation in a database table, and that table is accessed by subsequent web services in the chain to retrieve identity.
  C. OWSM sets the user in the Java Authentication and Authorization (JAAS) Subject when the first web service successfully authenticates, and the Java Subject is used by subsequent web services to access the identity.

  ---

  Propagating Identities through a Chain of Web Services

  A web service may invoke another web service which in turn may invoke yet another web service to complete a single transaction (this pattern is known as "chained web services"). Each of the services in the chain may be protected. Instead of checking which service is calling which other service, Oracle WSM allows you to check who the original user invoking the chain of Web services is. Oracle WSM policies can be used to propagate the original user's identity across the chained web services. Following successful authentication to the first web service in the chain, Oracle WSM sets the user as a Java Subject used throughout the transaction. When invoking another service, the Oracle WSM client policy picks up the user identity from the Java Subject, generates a SAML token based on the Subject 's information, and inserts the SAML token in the WS-Security header of the request message to be sent to the service provider. This allows all the web services in a chain to track the identity of the actual user calling a web service endpoint instead of having the identity of the prior service in the chain calling the first web service to get that information.

• Question 5:

  You want to leverage the Event Delivery Network (EDN) in your composite application for publishing and subscription.

  Which two components do you use?

  A. Business rule
  B. Mediator
  C. BAM adapter
  D. Spring component
  E. BPEL process
  B. Mediator
  E. BPEL process

  ---

  B: Example:

  Subscribing to the NewPO event

  1.

  Drag-and-drop a Mediator component on to the composite.

  2.

  Name the mediator receiveNewPO.

  3.

  Select Subscribe to Events for the Template.

  4.

  Click on the + to add an event. Select the NewPO event from the Event Chooser window.

  5.

  Click on OK to accept and create the mediator.

  6.

  Save all.

  7.

  Connect the receiveNewPO mediator to the routePO mediator:

  Etc.

  E: It is possible to subscribe to or publishing a Business Event from a BPEL Process Service Component

  Note:

  * The Event Delivery Network (EDN) in Oracle SOA Suite 11g provides a declarative way to use a publish/ subscribe model to generate and consume business events without worrying about the underlying message infrastructure.

• Question 6:

  View the Exhibit.

  

  The Exhibit shows a display from Enterprise manager Fusion Middleware Control where you can monitor and manage BPEL service engine properties. Where are all changes to this configuration stored?

  A. bpel_config.xml in MDS
  B. soa-infra-config.xml in $MW_HOME/soa/config on each physical host in cluster
  C. soa-infra-config.xml in the soa-infra-wls.ear file
  D. a temporary directory on each physical host in the cluster
  B. soa-infra-config.xml in $MW_HOME/soa/config on each physical host in cluster

  ---

  * The main controls of Oracle SOA Service Infrastructure can be configured using the soa-infra- config.xml file located in the DOMAIN_HOME/ config/soa-infra/configuration directory. In this file you can specify:

  / The data source JNDI name for process dehydration.

  / The server and callback URL

  / The audit level of information to be collected by the message tracking infrastructure.

  Note:

  *

  In Oracle BPEL Process Manager 11g, you specify Oracle BPEL Process Manager engine properties in bpel-config.xml and soa-infra-config.xml (both are accessible as MBeans).

  *

  You can change the SOA Infrastructure ServerURL property port from Oracle Enterprise Manager Fusion Middleware Control Console. This automatically updates the port setting in the soa-infra-config.xml file under $DOMAIN_HOME/

  config/Domain_Name/configuration.

  *

  Since 11.1.1.2, bpel-config.xml is no longer available into the file system and therefore the only chance for modification is through EM Console.

  *

  bpel-config.xml Configurations for BPEL Engine.

  Incorrect:

  Not C: Oracle SOA Service Infrastructure Services are contained in the soa-infra-wls.ear file.

• Question 7:

  Which two statements are true about messages that are marked "Exhausted" on the Recovery tab of the BPEL service engine in Enterprise Manager Fusion Middleware Control?

  A. They are messages that have exceeded the maximum number of auto recovery attempt.
  B. They can be marked again For auto recovery by using the "Reset" feature in the recovery console.
  C. Rejected messages are directly marked as "Exhausted."
  D. The "Refresh Alarm table" option can be used to resubmit Exhausted messages.
  E. Exhausted messages for Mediator components can be manually recovered from the same location in Fusion Middleware Control.
  A. They are messages that have exceeded the maximum number of auto recovery attempt.
  E. Exhausted messages for Mediator components can be manually recovered from the same location in Fusion Middleware Control.

  ---

  * Go to BPEL Recovery Console Access the Recovery page of the BPEL process service engine to perform message recovery. You can also access the Recovery page later by selecting Service Engines > BPEL from the SOA Infrastructure menu and clicking the Recovery tab in the resulting page.

• Question 8:

  Which capability or benefit is not applicable to Oracle Service Bus?

  A. Service mediation
  B. Service abstraction
  C. Translation and transformation
  D. Service creation
  E. Stateful processing
  E. Stateful processing

  ---

  Service Bus only can do stateless processing, and one of the most important benefits of Service Bus is the service abstraction

• Question 9:

  To add an xsi:type attribute to a target element, what needs to be mapped to the target element?

  A. A rename element on the canvas
  B. A recast element on the canvas
  C. An expression on the canvas
  D. A literal element on the canvas
  D. A literal element on the canvas

  ---

  Note:

  *

  The xsi:type attribute is added beneath the original element, as shown in the figure below. An S icon is displayed to indicate the node was substituted. You can map from any structural elements in the substituted type.

  *

  The xsi:type attribute is used to identify derived complex types (as well as complex types that have been derived from).

  *

  If you have elements in your XML file whose type is a complex type, xsi:type support in the XML editor lets you choose between the complex type and any other complex types derived from it.
