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?

Ans:

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?

Ans:

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?

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

Ans:

• 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?

Ans:

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?

• Delivery Bean
• JTA
• Engine Beam

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

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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?

Ans:

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

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

Ans:

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.
