Oracle SOA Interview questions will be discussed in this article, because of technology improvements, the market is seeing a tremendous growth in the demand for Oracle-skilled candidates. we’ve compiled a list of interview SOA questions and their responses.
Q1. What does SOA mean to you, and what are the advantages of implementing this architecture?
Service Oriented Architecture (SOA) is a type of architecture that may be utilized to create Enterprise Applications. Application components will interface with each other via interoperable services and a network communication protocol in this design.
The following are some of the advantages of using SOA.
- Components can be rearranged and remain loosely connected.
- It is possible to reuse business services.
- Confidentiality and security of data.
- Interfaces that are clearly specified.
- Better adaptability and upkeep.
Q2. What is Oracle SOA Suite, and what are the components that make it up?
Oracle SOA Suite is part of the Oracle Fusion Middleware software family.
This tool is based on SOA architecture and aids in the creation, management, and integration of services with application components so that SOA composite applications can be delivered as a single entity. There are five parts to this suite.
There are also the following service components:
- Process of BPEL
- Human Task Flow Decision Services by Oracle Mediator
The following are some of the binding components:
Q3. Could you perhaps clarify the differences between the architectures used in 10g and 11g?
The differences between 10g and 11g are listed below.
In 11g, but not in 10g, the SCA architecture is used.
Using a composite.xml file, all of the SOA components (such as BPEL, ESB, and so on) associated to a project can be deployed as a single entity in 11g. These components must be delivered to their respective servers individually in 10g.
Web Logic Server is the app server container for 11g, while OC4J is the container for 10g.
In Oracle 11g, Enterprise Manager manages all SOA components, whereas in Oracle 10g, each component has its own console.
Q4. What is the idea of SOA Governance?
In a service-oriented architecture, SOA governance is used to manage services.
This governance must be able to:
- Create them, When new services are necessary.
- Existing services should be updated.
- Manage the service lifetime.
- Maintain consistency by enforcing policy guidelines.
- Monitoring and fine-tuning service performance.
- Manages service permissions for users.
Q5. In SOA, how may a process be deployed?
Any of the following options can be used to deploy a process:
- EMC (Enterprise Manager Console).
- Scripting in WebLogic.
Q6. What is SCA and how can it help you?
Service Component Architecture (SCA) is a methodology for developing SOA-based applications and systems. The composite service consists of the assembly of various application components, which may all be delivered at the same time utilizing SCA.
The following are the many SCA specifications:
- Model Specification for Assembly.
- Binding Requirements.
- Implementation Specification for Components
- Specification of the Policy Framework
Q7. In the SOA framework, how can you establish loose coupling?
Loose coupling is done by abstracting and resolving discrepancies across systems in order to create seamless integration.
OSB makes this possible by facilitating communication between service clients and business processes. Through loose coupling, SOA leverages web services as building blocks to achieve enterprise integration and component re-use.
Q8. Can you tell the difference between a mediator and an OSB?
Mediator differs from OSB in the following ways:
- A mediator is a component of a composite application that mediates between the various components within and outside of the composite application. OSB, or Oracle Bus Service, is a stand-alone ESB that mediators between heterogeneous clients and services without becoming a part of them.
- An OSB cannot be used as a SCA component, although a mediator can.
- The JDeveloper IDE can be used to develop a mediator, whereas the Eclipse IDE or Web Console can be used to develop an OSB.
Q9. Is Oracle Fusion Middleware compatible with SOA?
Yes, SOA is a component of Oracle Fusion Middleware that acts as a user interface within the larger Fusion platform.
Q10. What is the difference between choreography and orchestration?
Choreography and orchestration are important components of the cooperation layer in service orientation, such as SOA and BPM.
Systems are integrated during Choreography without following any business processes. There is no established process for controlling the integration, and it is carried out in accordance with the defined level sequence.
In orchestration, a central process, which might be a Web Service, is in charge of all other web services participating in the system integration. This central coordinator will oversee the execution of the numerous web services involved in the operation and ensure that the integration is completed.
Q11. Can you explain what an ERP system is?
ERP stands for Enterprise Resource Planning. It is a commercial software solution that enables a company to automate and integrate numerous business operations while sharing common data across several companies.
ERP software often uses a single database, application, and interface to combine several aspects of an operation, such as product planning, development, and manufacturing, sales, marketing, and so on.
Q12. Explain the architecture of Oracle Apps.
Oracle Apps is a multi-tier architecture in which the application server acts as a bridge between clients and database servers.
As a result, the following are the components of this architecture:
- Application servers Clients
- Servers for databases
Clients will make the request for the database to perform an operation. The application server will operate as an intermediary between the client and the database, relaying the client’s request to the database and returning the requested data.
Q13. Is it possible to build tables in the APPS schema?
No, we won’t be able to build tables in the APPS schema, which will only contain synonyms.
Q14. What is a flexfield, exactly? Make a list of the many types.
Flexfield is a database field that has the ability to define reporting structures that are relevant to specific companies. Segments or subfields make up a flexfield.
Flex fields are divided into two categories:
- Key flexfields: They’re utilised to keep track of important data points.
- Descriptive flexfields are user-defined and customizable flexfields.
Q15. What factors should you take into account while establishing responsibility in Oracle Apps?
A duty is a collection of elements. These are the following:
- Menu (mandatory): A menu is a hierarchical collection of forms.
- Data Group (obligatory): It specifies the relationship between Oracle App products such as forms, reports, and concurrent programmes, and Oracle database identifiers.
- Request Security Groups and Responsibilities (mandatory): A request security group is a request group that is assigned to a responsibility.
- Function and Menu Exclusions (optional): A function and menu exclusion rule may or may not be coupled with a responsibility.
Q16. What is a Value Set, exactly? Make a list of its numerous sorts.
The value set, as the name implies, is a preset collection of values used by Oracle for validation. It prevents the end-user from entering trash data by allowing them to choose from a predefined set of values.
There are eight different types of value set validations that Oracle offers. These are the following:
- None at all (validated minimally)
- Special (advanced)
- Pair (advanced)
- Translatable Independent
- Translatable Dependent
Q17. How can we use SQL * Loader to import data into a database?
SQL * Loader is a program that imports data from external files in bulk.
The following are some of the characteristics of this command-line utility:
- They have the ability to load selectively.
- They have the ability to load multiple tables.
- Files in a variety of formats are supported.
Q18. What exactly do you mean by concurrent programs?
A concurrent program is an executable file that may run in parallel with other program and make full use of the hardware resources available. These applications would often be long-running and data-intensive. A request group can be formed by combining them with reports.
Q19. What is the content of the APPL_TOP directory?
The APPL directory, also known as the APPL_TOP directory, houses Oracle e-business suite files.
The files, as well as their relative folders, are located in this directory:
- Files related to technology
- Product specific files
- Environment files for Oracle’s e-business suite.
Q20. What do you mean by a collection of books?
The collection of books is a financial reporting entity, according to the answer. It establishes a company’s or a group of firms’ functional currency, account structure, and calendar.
There are two kinds of book sets.
- Primary: It is made up of usable money.
- Secondary: It is made up of currency reporting.
Q21. In terms of SOA, what are FTP and HA File Adapters?
The FTP and File adapters should be used according to the high availability basis when running an application in a clustered environment. However, you must be aware of the incoming and outgoing features, which are important in the operation of file adapters.
Typically, there are two sorts of file adaptation procedures. Inbound and outbound are other terms for them. Various sorts of administrative records regulate the incoming feature.
It’s also good at avoiding managed servers when a file is being read from a directory. However, you should keep in mind that the data that the servers read will be referenced in such a way that it can be saved in the directory for future use.
The outbound methods, on the other hand, emphasize the fact that it is regulated by a table of DB Mutex in the dehydrating store.
The outbound approach ensures that duplication is avoided at all costs, which is beneficial to the application development concept.
