    50 . What do you understand by SOA and what are the benefits of using this architecture?


      SOA stands for Service Oriented Architecture, which can be used to develop Enterprise Applications. Using this architecture, application components will interact with each other using interoperable services by following the communication protocol over the network.

        Benefits of using SOA are :

      • Components stay loosely coupled and can be reconfigured.
      • Business services can be reused.
      • Data security & confidentiality.
      • Well defined Interfaces.
      • Better flexibility and maintenance.

    51. What is Oracle SOA Suite and what are its different components?


      Oracle SOA Suite belongs to the Oracle Fusion Middleware group of software products.

      This tool is based on SOA architecture and helps in creating, managing & integrating services with the application components so as to deliver SOA composite application as one unit. This suite consists of five components.

      Service components further consist of :

    • BPEL Process
    • Oracle Mediator
    • Human Task Flow
    • Decision Services
    • Binding components include :

    • Services
    • References

    52. Can you explain the difference between architecture followed in 10g & 11g?


      Given below are the differences between 10g and 11g :

    • SCA architecture is followed in 11g but not in 10g.
    • In 11g, all of the SOA components (like BPEL, ESB, etc., related to project can be deployed at once as a single unit using a composite.xml file. In 10g, these components need to be deployed individually to the respective servers.
    • App server container for 11g is Web Logic Server while for 10g is OC4J.
    • In 11g, Enterprise Manager takes care of all SOA components while in 10g separate consoles are maintained for each component.

    53. What is the concept of SOA Governance?


      SOA governance is introduced to administrate services in a service-oriented architecture. This governance is required to :

    • Create new services when required.
    • Update existing services.
    • Manage the lifecycle of services.
    • Enforce the rules on policies to maintain consistency.
    • Monitoring and tuning performance of services.
    • Manages user permissions on services.

    54. How can a process be deployed in SOA?


      A process can be deployed using any of the below options :

    • JDeveloper
    • EMC(Enterprise Manager Console.
    • WebLogic Scripting.

    55. What is SCA and how is it useful?


      Service Component Architecture (SCA. is a model for building applications and systems using SOA concepts. The composite service has the assembly of different components of the application and these components can be deployed together at once using SCA.

      The various specifications of SCA are :

    • Assembly Model Specification. .
    • Binding Specification.
    • Components Implementation Specification.
    • Policy Framework Specification.

    56. How can you achieve loose coupling in the SOA framework?


      Loose coupling can be achieved by abstracting and resolving the differences between different systems so as to provide seamless integration. OSB facilitates the same and resolves the issues between service clients and business systems. SOA uses web services as building blocks to accomplish enterprise integration and component re-usage through the loose coupling.

    57. Can you differentiate between mediator and OSB?


      Mediator can be differentiated from OSB as :

    • A mediator is part of a composite application and is used to mediate between the different components within and outside a composite application. While OSB i.e. Oracle Bus Service is a standalone ESB which mediates with heterogeneous clients and services without being a part of them.
    • A mediator can be deployed as an SCA component while an OSB cannot.
    • For a mediator, development can happen through JDeveloper IDE while for OSB, it can be done using Eclipse IDE or Web Console.

    58. Is SOA a part of Oracle Fusion Middleware?


      Yes SOA is a part of Oracle Fusion Middleware behaving as a UI within the big Fusion platform.

    59. How is choreography different from orchestration?


      Choreography and orchestration, are critical parts of the collaboration layer within service orientation i.e. SOA & BPM.

      During Choreography, systems get integrated without following any business processes. There is no process defined to control the integration and it is done as per the defined sequence of levels.

      In Orchestration, a central process which can be a Web Service itself controls the other web services involved in the integration of systems. This central coordinator will coordinate the execution of various operations of web services involved in the operation and completes the integration.

    60. Can you define an ERP System?


      ERP stands for Enterprise Resource Planning. It is a business software system that allows an organization to automate and integrate with the various business processes sharing common data across enterprises.

      ERP software typically integrates the different facets of an operation like product planning, development, and manufacturing, sales, marketing, etc. using a single database, application, and interface.

    61. Explain Oracle Apps architecture.


      Oracle Apps is a multi-tier architecture environment where the application server serves as an interface between clients and database servers. Hence, the components of this architecture are :

    • Clients
    • Application servers
    • Database servers
      • Clients will initiate the request for an operation to be executed by the database. The application server will act as an intermediate layer by sending the client request to the database and providing the requested data to the client.

    62. Can we create tables in APPS schema?

    • Key flexfields: They are used to record key data elements.
    • Descriptive flexfields: They are user-defined flexfields and can be customized.

    64. What are the different components you should consider while defining responsibility in Oracle Apps?


      A responsibility is a group of components. These are :

    • Menu (mandatory) : It is an arrangement of forms in a hierarchical manner.
    • Data Group (mandatory) : It defines the mapping between Oracle App products like forms, reports, concurrent programs, and Oracle database Ids.
    • Responsibilities and Request Security Groups (mandatory) : A request security group is the request group assigned to a responsibility.
    • Function and Menu Exclusions (optional) : Responsibility may or may not have an associated function and menu exclusion rules.

    65. What is a Value Set? List its various types.


      As the name itself suggests, the value set is a predefined list of values used by Oracle for validation. It restricts the end-user to enter junk data by providing an option to select a value from the predefined set of values.

      Oracle supports eight types of value set validations. These are :

    • None (validated minimally.
    • Independent
    • Dependent
    • Table

    67. What do you understand by Concurrent programs?


      An executable file that can execute simultaneously with the other programs and utilize the hardware capacity to the fullest is called the concurrent program. Generally, these types of programs would be long-running and data-intensive. They can be grouped with reports to form a request group.

    68. What does the APPL_TOP directory contain?


      APPL directory stores Oracle e-business suite files and hence it is commonly known as APPL_TOP directory.

      This directory contains the files along with the relative directories :

    • Technology files
    • Product files
    • Oracle e-business suite environment files

    69. What do you understand by a set of books?


      The set of books is a financial reporting entity. It determines the functional currency, account structure, and calendar for a company or a group of companies.

      There are two types of set of books.

    • Primary: It consists of functional currency
    • Secondary: It consists of reporting currency

    70. What is SOA?


      SOA is also known as the acronym for Service Oriented Architecture. It is also known as a framework for building applications that can be used for commercial purposes. It is important to note in this context that during the development process of these applications, SOA uses loosely coupled strategies. These can be combined to achieve a considerable amount of functionality.

    71. Shed light on the various principles on which SOA is based?


      SOA is based on the following principles. They are as follows :

    • Flexible
    • Re-usability
    • Loose Coupling
    • Interoperability

    72. Do you think that Oracle Fusion is the same as that of Oracle SOA?


      The answer is no due to the fact that SOA is one of the integral parts of Oracle Fusion. Moreover, SOA acts like the user interface in the Oracle Fusion platform.

    73. What is SCA with respect to the Oracle SOA platform?


    • SCA is also known as the Service Component Architecture. This type of architecture provides an underlying programming model in order to design an application in the Oracle environment.
    • It is also regarded as a model whose primary purpose is to encompass a broad range of service strategies and technologies.
    • In this context, it is also important to note that it facilitates the necessary technical know-how to connect the access methods.

    74. What is the fundamental difference between components and services?


    • You should be well aware of the fact that services are also known as a logical coupling of various parts so that the functionality of developing a business application can be achieved.
    • On the other hand, the components are also referred to as implementation approaches in order to create a service. You should also be aware of the fact that these components can be in C++ and Java.
    • On the contrary, the services would be exposed in a general format that resembles web services.

    75. In SOA, is there a need to design systems from the beginning?


      1. The answer is no. It is so because if you need to incorporate an existing system, you have to be on the lookout to facilitate loosely held wrappers.

      2. These loosely-organized wrappers would always wrap your custom systems and would go a long way in exposing the functionality of the system in a significant manner.

    76. Describe a few hurdles that come in the form of implementing SOA?


      Here is the list of obstacles that come in the way of achieving SOA. They are as follows :

    • Scarcity of skills
    • Less return on investment on implementation of SOA projects.

    77. Do you need the ability of SOA Governance while getting started?


    • In order to be successful in your endeavors of implementing SOA, you need to consider the business values that are involved with it from the beginning.
    • Quite interestingly, one of the primary benefits which you would get from the implementation of SOA is improved knowledge in the alignment of business with IT.
    • It is crucial for you to have proper knowledge of SOA governance as it would make you aware of the procedures and decision rights for IT and businesses to work collaboratively.
    • However, you do not need a lot of SOA governance to get started but a little bit of it.

    78. Describe choreography in SOA?


      In choreography, there is an utter lack of business processes to control. Each system in choreography would seamlessly mix into various components.

    choreography in SOA
    Choreography in SOA

    79. How does orchestration differ from choreography?


      As opposed to choreography, in orchestration, there is a business process that usually controls a variety of services that are also a part of the integration process.

    80. List the number of ways in which a process can be deployed?


      There usually exists three ways with the help of which a process can be implemented. They are as follows :

      1. Through the use of Enterprise Manager Console

      2. Through the use of Weblogic Scripts

      3. Through the use of JDeveloper

    81. List the various types of design patterns that are used in the implementation of SOA?


      Here is the list of multiple types of design patterns that are widely used in the process of implementing SOA.

    • Delayed response or asynchronous
    • Fire and forget or synchronous
    • Synchronous

    82. How can you increase the timeout related to a transaction in SOA?


      In order to increase the transaction timeout, a lot of value needs to be changed to be on par with the value of the expected timeout. They are as follows :

    • Delivery Bean
    • JTA
    • Engine Beam

    83. Define DVM and its utility in the SOA implementation process?


      DVM is also known as Domain Value Map. It is defined as a static mapping between the trigger system and the source. It can also be used in transformations. Moreover, this value can be changed with the help of the SOA Composer.

    84. Shed light on the dehydration store in an SOA environment?


      A dehydration store is also known as a database where the instances are stored. The database gets dehydrated or devoid of values when there is a constant occurrence of various futile activities.It also saves the information when the application runs for an extended period of time.

    85. Shed light on the primary difference between DVM and XREF?


      XREF is also known as a dynamic domain where the values of the XREF can be populated on a dynamic basis. Moreover, the data after the input process gets stored in the table named in the form of XREF_DATA. On the other hand, DVM is also known as a static mapping that lies between a source and target system. It can also be used in alterations.

    86. What is a decision service with respect to the SOA environment?


      It is essential for you to note that Oracle Suite would provide you support for the various types of decision components which would support the rules of the Oracle business. Quite interestingly, a decision component is also known as a mechanism that is widely used for publishing various types of regulations. Moreover, these rule sets are also known as being reusable.They can be triggered with the assistance of a plethora of business processes. Furthermore, these rules can be altered without rewriting the code.

    87. What do you mean by the XA Data Source? Shed light on the primary differences between the XA and non-XA data source?


      An XA data source refers to that type of transaction that comprises coordinating with the transaction manager. It has one or more databases, and all of these databases are involved in a single global operation.On the other side, the non-XA data sources are of those types which are entirely devoid of a transaction coordinator. In non-XA data sources, a majority of transaction work is carried out by a single resource.

    88. Define MDS with respect to SOA practices?


      MDS is also known by the name of Metadata store. MDS can be used in the code generation process. With the help of MDS, the size of the JAR file would be significantly reduced.Moreover, with the implementation of MDS, the duplication of the artifacts can be avoided amongst the various services.

    89. Describe the process in which you can protect the web services with the use of Oracle Suite?


      During the time of access, the services have to be restricted to the group. In this manner, the facility gets secured with the help of a Web Service Manager.

    90. What do you mean by the singleton feature in Oracle SOA?


      The singleton feature of SOIA comes to the fore when the message processing procedure should be managed with the help of only one OA Server. This is the reason where the singleton property needs to be executed in the levels of the adapter.

    91. What are FTP and HA File adapters with respect to SOA?


      1. During the execution of an application in a clustered environment, the FTP and File adapters should be used as per the high availability basis. However, you also have to know about the inbound and outbound features that play a crucial process in the working process of file adapters.

      2. There are usually two types of file adapting procedures. They are also known as inbound and outbound. The incoming feature is controlled by various types of administrative records.

      3. It is also quite adept at avoiding the managed servers while the reading process of a file is going on in the directory. However, you should also note that the reference to the data that are read by the servers would be maintained in such a manner that they can be kept in the directory for future use.

      4. On the other hand, the outbound procedures lay emphasis on the fact that it is controlled by a table of DB Mutex which exists in the dehydration store.

      5. The outbound procedure ensures that the duplicity can be avoided at all costs which are great for the notion of application development.

    92. Define pick activity concerning SOA?


      Pick activity is associated with the pickup of messages from the source. It also comprises a variety of multiple operations. It is also important to note that the BPEL process needs to transmit the signals from a plethora of numerous source systems.

      In this context, it is interesting to mention that peak activity should comprise at least one message branch.

    93. How to predefine errors in BPEL?


    • Custom errors
    • Timed-out errors
    • BPM errors
    • Validation Errors

    94. Define a mediator with respect to the implementation process of SOA?


      The mediator is responsible for interconnecting a variety of composite applications. It is also quite adept at exposing different interfaces with a varied number of components.

    • Moreover, the mediator can also perform various kinds of duties which comprise filtering so that the routing decisions can be implemented.
    • On the other hand, it is also important to note that the composite editor which is present in the JDeveloper would give you the usability to illustrate the interface.
    • Moreover, with the help of the mediator, you can change data from one representation to the other. It is also one of the critical functionalities of the mediator.

    95. Shed light on plumbing layers with respect to SOA?


      The plumbing layer is also known as a special layer that usually sheds light on the management of various computer resources like web servers and databases. This type of architecture carries utmost importance in order to identify the service.

    96. Shed light on the business layers?


      In SOA, one can segregate the structure into two segments. The primary layer is the business layer. It has direct importance to the activities of a business.

    Shed light on the business layers
    Shed light on the business layers

    97. Describe the appropriate time when you would opt for the Sync Process?


      In order to answer this question, you need to take into account the right time of using the Sync Option. It is usually recommended that during the time when the services return the response in a matter of few seconds, one should opt for the BPEL process.

      It is so because if you do not use the BPEL process, the application cannot progress which can be detrimental to its development

    98. What are SOA Principles?


    • Loose coupling
    • Re-usability
    • Interoperability
    • flexible
