If you are looking for a job related to Oracle SOA, you must prepare for the 2023 Oracle SOA Interview Questions. Every interview is indeed different as per the various job profiles. Here, we have prepared the essential Interview Questions and Answers to help you succeed in your interview.
This 2023 Oracle SOA Interview Questions article will present the ten most important and frequently asked Oracle SOA interview questions. These questions are divided into two parts as follows:
Part 1 – Oracle SOA Interview Questions (Basic)
This first part covers basic Interview Questions and Answers
Q1. What is SOA, and explain its architectural benefits?
SOA is the acronym for Service Oriented Architecture and helps develop the integration plugins or services for integrating different cross-technological or cross-platform applications. SOA architecture has several benefits, such as the development of loosely coupled components, easy reconfiguration of the existing services, reusing the current SOA services without affecting the business functionalities, Ensures Data Confidentiality and Security, and Better Maintenance and Flexibility in maintaining the services.
Q2. What are the different components involved in the SOA Architecture?
The different components present in the SOA Suite are as below–
- Process Layer or Orchestration layer
- Access Framework
- Business Activities Monitoring
- Operational Data Stores
- Partners, Suppliers, and Customers
The above components are not exhaustive and also include several other components which are necessary, such as it maintaining loosely coupled components which are essential for better performance and higher availability.
Q3. What are the different types of Services available in SOA?
The different types of Services available in SOA Service-oriented Architecture are SOAP and REST-based, which are explained below :
SOAP-Based: The SOAP (Simple Object Access Protocol) based services are exposed as XML (Extensible Markup Language) based message format. The generation of these XML messages is based on WSDL standards. WSDL is the Web Services Description Language that defines the standards for SOAP Web Services.
REST-Based: The REST-based or RESTful based Web Services are exposed in JSON format by using the HTTP communication protocols with different methods such as GET, HEAD, POST, PUT, DELETE, CONNECT, OPTIONS, and TRACE. WADL (Web Application Description Language) describes the REST services like WSDL. You can use SOAP UI and Postman UI tools to test SOAP and REST Web Services, respectively, and SOAP UI can be used for both types.
Q4. What are the important features of the Oracle Service Bus (OSB) component in SOA Suite?
This is the basic Oracle SOA Interview Question asked in an interview. The key features of the Oracle Service Bus component are as below –
- Multiprotocol Messaging Support
- Message Brokering
- Content-Based Routing
- Service Switching
- Service Bus Security
- Message Security, Identity, Authorization, and Authentication
- Service Discovery
- Resource Cache
- Messaging protocols such as HTTPS, SOAP, SMTP, JMS, FTP, File, MQ, Tux, etc.,
- Dynamic Transformation
- Error Handling
- Change Center
Q5. What are the core features of the SOA suite component Oracle Service Bus?
The core features of the Oracle Service Bus component of Oracle SOA Suite are Service Integration, Service, Security, Service Management, and Service Composition. The Service Integration features are used for the functionalities such as message brokering, integrating disparate service end-points, and mediating & exposing the services for reusing purposes. Service Security features provide functionalities for service authentication and authorization, message security enforcement, and user identity validation. Functionalities, including defining message routing logic, service setup, message transformation, message verifying, and registry purposes, employ Service Composition capabilities. Service Management features enable users to manage service activities, monitor service availability, and perform related functions.
Part 2 – Oracle SOA Interview Questions (Advanced)
Let us now have a look at the advanced Interview Questions.
Q6. What are the different components involved in SOA Suite?
The different components present in the SOA Suite are as below:
- BPEL Process Manager
- Human Workflow
- Business Rules Adapters
- Adapters such as File, JMS (Queue and Topic), AQ, DB Adapter Business Events
- Events Delivery
- Network Complex
- Event Processing
- BAM (Business Activity Monitoring)
- Oracle ESB/OSB Oracle
- B2B, OWSM and JDeveloper IDE
Q7. What communication types are used in the Oracle Service Bus for messaging purposes?
The different communication types used for the messaging paradigms in Oracle Service Bus architecture are Synchronous request/response, Asynchronous publish one-one, Asynchronous publish one-many, and Asynchronous request/response (synchronous-to-asynchronous bridging).
Let us move to the next Oracle SOA Interview Questions.
Q8. What message transformation features are available in Oracle Service Bus in SOA Suite?
The different messaging transformation features of the Oracle Service Bus in SOA Suite are as below –
- Validating the incoming messages against different schemas
- Selecting a target service or different services based on the messaging content or such as message headers
- Transforming the messages based on the target services
- Transforming the messages based on the XQuery or XSLT
- Supports the transformations on both XML and MFL message formats
- Message enrichment features
- Supports calls to the different Web services to gather additional data for transformation
Q9. What is Metadata Store in SOA Suite?
These are the most asked Oracle SOA Interview Questions in an interview. The Metadata Store Is an SOA Suite 11g feature for sharing the SOA Artifacts. This ensures the SOA Artifacts such as EBMs, XML Schemas, Fault Policies, WSDLs, Rule repositories, and Service Data Objects (SDOs). You can configure the Metadata Store as either database-based or file-based.
Q10.What are the Decision component services in SOA?
The Decision Service Component is a rule engine, a rule decision function in the form of a web service. The different components of Decision Service are as follows:
- Decision Rules and Decision Tables.
