Oracle Application Integration Architecture 11g Essentials

Question No: 31

A BPEL is needed to support nonidempotent application service

  1. compensation handler

  2. throw block

  3. switch construct

  4. exception handler

Answer: A

Explanation: If a scope requires a compensation handler, the service that requires compensation should be marked as non-idempotent by setting the quot;idempotentquot; property value to quot;false.quot; This will cause Oracle BPEL Process Manager to start a new transaction after invoking the non-transactional resource.

Note: BPEL includes the concept of an invocable Compensating Transaction. This is similar to an exception handler, and is defined at the scope level. However, it is explicitly invoked only by the quot;Compensatequot; activity. Compensation is intended to allow the application of reversing operations to systems that cannot participate in transactions, or when it has been decided that the systems should not operate as part of transactions. For example, a Web Service might allow inventory to be decremented, but an error makes it necessary to roll back the process. In this case, a compensation handler would be defined to call the Web Service to increment the inventory, effectively providing a reversing transaction. This allows you to define rollback activities and associate them with the code that performs the operations that may need to be reversed. This is also very useful in that it allows some exceptions to be handled without undoing all of the work.

Note: An idempotent activity is an activity that can be retried (for example, an assign

activity or an invoke activity). The instance is saved after a nonidempotent activity. This property is applicable to both durable and transient processes.

    Question No: 33

    Which statement is true about AIA clustering?

    1. AIA clustering setup is dependent on SOA cluster setup.

    2. Multiple PIPs should always be deployed on different AIA clusters.

    3. Multiple PIPs should always be deployed on the same AIA Home.

    4. AIA clustering setup is independent of SOA cluster setup.

    Answer: A

    Explanation: Cluster Deployment mode

    This Installation mode is used to deploy AIA on an existing SOA Suite Cluster to derive high-availability, effective workload distribution, increased throughput, performance etc. SOA Suite Cluster has to be successfully setup according to the SOA Suite 11g Enterprise Deployment Guide (and tested with samples) before proceeding with AIA Installation on the cluster.

    The Installer will automatically detect the presence of a SOA Cluster and prompt the user with fields for appropriate additional information.

    Question No: 34

    Which AIA component is used to plan the services to be deployed?

    1. AIA Installation Driver

    2. AIA Lifecycle Workbench

    3. AIA Composite Application Validation System

    4. AIA Deployment Plan Generator

    Answer: D

    Explanation: The Deployment Plan Generator generate a deployment plan.

    Deployment Plan Generator produces the following output:

    • Deployment Plan: The deployment plan that is generated is very specific to the BOM.xml and ODIBOM.xml which are given as input. The services which are specified in BOM.xml can be deployed and configured by using this deployment plan. The artifacts list provided in the ODIBOM.xml is processed and imported into the ODI with the deployment plan.

      Deployment Plan Generator generates a combined deployment plan if both the BOM and ODIBOM are provided. This deployment plan is executed by feeding it to AID.

    • Undeployment Plan.

    • Harvester Settings File.

    Question No: 35

    Which one best describes the type of information expressed by a collection of EBOs?

    1. data model

    2. data repository

    3. generic operations

    4. exchanged messages

    Answer: A

    Explanation: EBOs (Enterprise Business Objects) have the following characteristics:

    • They contain components that satisfy the requirements of business objects from the source and target application data models.

    • EBOs differ from other data models in that they are not data repositories.

      Instead, they provide the structure for exchanging data. XML provides the vocabulary for expressing business data. The XML schema is an XSD file that contains the application- independent data structure to describe the common object.

    • Each EBO is represented in an XML schema (XSD) file format.

    Reference: Oracle Fusion Middleware Concepts and Technologies Guide for Oracle Application Integration Architecture Foundation Pack,Introduction to EBOs

    Question No: 36

    Which two statements are true about designing and implementing an EBS?

    1. An EBS cannot expose operations beyond the standard CRUD operations.

    2. Each action present in an associated EBM will be implemented as a service operationin EBS.

    3. If an operation acts on more than one business object, it should reside in an entity EBS.

    4. A routing rule will be created for each operation in an entity-based EBS

    Answer: C,D

    Explanation: Note:EBS (Enterprise Business Services) are the foundation blocks in the Oracle Application Integration Architecture (AIA). EBS represent the application or implementation-independent web service definition for performing a business task. The architecture facilitates distributed processing using EBS.

    An EBS is a service interface definition, currently manifested as an abstract Web Service Definition Language (WSDL) document, which defines the operations, message exchange pattern, and payload that are applicable for each operation of a service.

    Question No: 37

    How will you add customized rules on PIP Auditor?

    1. by adding new set of rules to Rules.xml and by creating new test suites

    2. by modifying the PIP Auditor source code

    3. customized rules cannot be added

    4. by modifying the config.properties file

    Answer: A

    Explanation: PIP Auditor uses the Rules.lt;release numbergt;.xml file, which contains rules in a rule language that is specific to and optimized for PIP Auditor. Use the rules file specific to the release for which you want to run audits.

    To add a new rule for execution by PIP Auditor, add it in the Custom Rule file. A Corresponding Test must be added to the Custom Test suite file for a new rule to be executed.

    Creating Custom Rules for PIP Auditor

    Question No: 38

    Which role is typically associated with decomposing a business process?

    1. Business Analyst

    2. Solution Architect

    3. Developer

    4. Database Administrator

    Answer: A

    Explanation: Phase: Analysis

    This phase focuses on the business analysts and end users analyzing an “as-is” process and capturing the issues and challenges facing this process, i.e. delays, disconnects, etc. A business process can be decomposed into several

    sub-processes, which have their own attributes, but also contribute to achieving

    the goal of the super-process. The analysis of business processes typically includes the mapping of processes and sub-processes down to activity level. (See functional decomposition later in this document). Once the issues and challenges have been uncovered, an improved “to-be” process is designed to resolve these issues.

    Note: Process Analyst – Also commonly known as Business Analyst (or Business Process Analyst), the Process Analyst is primarily responsible for capturing and managing the graphical business process models. The Process Analyst also captures related business process requirements, drives process optimization, recommends changes, and

    evaluates change requests from the business. The Process Analyst has business and modeling skills and liaises with the Process Architect for technical coordination.

    The Process Analyst has primary responsibility for making incremental process improvements (as opposed to major change from the business leadership). The Process Analyst also

    • Identifies and codifies business rules

    • Uses business objectives as input to determine KPI

    • Provides business specification for new capabilities

    • Directs UAT

    Question No: 39

    Which two statements are true about a Service Solution Component?

    1. It represents a proposed service.

    2. It represents an actual service.

    3. Service Solution Component information flows upstream to Service Constructor.

    4. Service Solution Component information flows downstream to Service Constructor.

    Answer: A,D

    Explanation: A:A service solution component is a chunk of functionality within the scope of a task that is implemented as an AIA service artifact. For example, a service solution component correspondsto an Application Business Connector Service (ABCS), Enterprise Business Service (EBS), or Enterprise Business Flow (EBF). A service solution component conveys the functionality that the AIA service artifact must fulfill.

    Developers work with functional product managers and solution architects to validate the project design and decomposition. The developers ultimately take on the task of implementing the service solution component as composites.

    D: Each lifecycle stage supports the downstream activities

    • Automation: auto-generate inputs to be consumed by downstream activities

    • Consistency: Information trickles downstream from one stakeholders to another automatically to

      ensure consistency

    • Productivity: More scalable, productive, and lean PIP development given infrastructural support throughout the lifecycle.
