The various specifications of the SCA are :

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

56. How can achieve a loose coupling in SOA framework?

Ans:

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

57. Can differentiate between a mediator and OSB?

Ans:

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

58. Is SOA a part of a Oracle Fusion Middleware?

  • In this context, it is also important to note that it facilitates a necessary technical know-how to connect the access methods.

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

Ans:

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

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

Ans:

    1. 1.It is so because if need to incorporate an existing system, have to be on the lookout to facilitate a loosely held wrappers.
    2. 2. These loosely-organized wrappers would always be wrap a custom systems and would go a long way in exposing functionality of the system in a significant manner.

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

They are as follows :

  • Delivery Bean
  • JTA
  • Engine Beam

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

Ans:

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

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

Ans:

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

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

Ans:

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

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

Ans:

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

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

Ans:

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

88. Define a MDS with respect to SOA practices?

Ans:

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

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

Ans:

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

90. What is mean by a singleton feature in Oracle SOA?

Ans:

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

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

Ans:

    1. 1. During execution of an application in a clustered environment, the FTP and File adapters should be used as a per high availability basis. However, also have to know about inbound and outbound features that play a crucial process in a working process of file adapters.
    2. 2. There are usually a two types of file adapting procedures. They are also known as a inbound and outbound. The incoming feature is controlled by the various types of administrative records.
    3. 3. It is also quite adept at avoiding the managed a servers while the reading process of a file is going on in directory. However, should also note that the reference to a data that are read by a servers would be maintained in such manner that they can be kept in the directory for future use.
    4. 4. On the other hand, the outbound procedures lay an emphasis on the fact that it is controlled by the table of DB Mutex which exists in the dehydration store.
    5. 5. The outbound procedure ensures that a duplicity can be avoided at all costs which are great for notion of application development.

92. Define a pick activity concerning SOA?

Ans:

Pick activity is associated with a pickup of messages from source. It also comprises a variety of the multiple operations. It is also important to note that tBPEL process needs to transmit the signals from plethora of numerous source systems.In this context, it is interesting to mention that peak activity should be comprise at least one message branch.

93. How to predefine the errors in BPEL?

Ans:

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

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

Ans:

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

  • Moreover, the mediator can also perform a 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 composite editor which is present in a JDeveloper would give the usability to illustrate the interface.
  • Moreover, with the help of a mediator, can change data from one representation to other. It is also one of the critical functionalities of mediator.

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

Ans:

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

96. Shed light on a business layers?

Ans:

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

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

Ans:

Need to take into a account the right time of using a Sync Option. It is usually recommended that during a time when the services return the response in a matter of few seconds, one should opt for a BPEL process. It is so because if do not use the BPEL process, the application cannot be progress which can be detrimental to its development

98. What are the SOA Principles?

Ans:

  • Loose coupling
  • Re-usability
  • Interoperability
  • flexible

99. How can make a request dynamic?

Ans:
