Oracle SOA Interview Questions

Q1) Define 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.

Q2) Shed light on the various principles on which SOA is based
SOA is based on the following principles. They are as follows:

1. Flexible
2. Re-usability
3. Loose Coupling
4. Interoperability

Q3) Do you think that Oracle Fusion is 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.

Q4) Define 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 necessary technical know-how to connect the access methods.

Q5) 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 which resembles like web services.

Q6) In SOA, is there a need to design systems from the beginning?
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. 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.

Q7) 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:

1. Scarcity of skills
2. Less return on investment on implementation of SOA projects

Q8) 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 on SOA governance as it would make you aware of the procedures and decision rights for IT and business to work collaboratively. However, you do not need a lot of SOA governance to get started but a little bit of it.

Q9) Describe choreography in SOA
In choreography, there is an utter lack of business process to control. Each system in choreography would seamlessly mix into various components.

Q10) How does orchestration differ from choreography?
As opposed to choreography, in orchestration, there is a business process which usually controls a variety of services which are also a part of the integration process.

Q11) 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

Q12) 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

Q13) 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:

1. Delivery Bean
2. JTA
3. Engine Beam

Q14) Define DVM and its utility in the SOA implementation process
DVM is also known by 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 SOA Composer.

Q15) Shed light on the dehydration store in an SOA environment
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.

Q16) 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.

Q17) 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 which 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 the rewriting the code.

Q18) 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 which comprises of coordinating with the transaction manager. It has one or more than 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.

Q19) 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. Wirth the help of MDS, the size of JAR file would be significantly reduced. Moreover, with the implementation of MDS, the duplication of the artifacts can be avoided amongst the various services.

Q20) 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 Web Service Manager.

Q21) What do you mean by 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.

Q22) Define FTP and HA File adapters with respect to SOA
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. 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.

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

Q23) Define pick activity concerning SOA
Pick activity is associated with the pickup of messages from the source. It also comprises of 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 of at least one message branch.

Q24) How to predefine errors in BPEL?

1. Custom errors
2. Timed-out errors
3. BPM errors
4. Validation Errors

Q25) 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 the varied number of components. Moreover, the mediator can also perform various kinds of duties which comprise of 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.

Q26) Shed light on plumbing layers with respect to SOA
The plumbing layer is also known as a special layer which usually sheds light on the management of various computer resources like web server and database. This type of architecture carries utmost importance in order to identify the service.

Q27) 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.

Q28) 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.

Q29) What are SOA Principles?

1. Loose coupling
2. Re-usability
3. Interoperability
4. Flexible

Q30) How can you make a request dynamic?
If you are on the lookout to send a request to a variety of services that have the same value of WSDL, then the application has to make in a dynamic manner. You can make the requested dynamic by making use of the addressing schema. In this manner, the desired objectives can be met in an efficient way.
