Interview questions for Oracle Integration Cloud

1. What is Integration in Oracle Integration Cloud?

Ans: Integration are the main ingredient of Oracle Integration, An Integration includes trigger (source) connection and invoke (target) connection and the field mapping between those two connections.

2. What is adaptor in Oracle Integration Cloud?

Oracle Integration Cloud (OIC) Adaptor is a abstract way to connect to any application with the help of box adapter. There are 50+ adapters available in OIC, below are the categories

• Oracle Adapter(Oracle Sales Cloud, Oracle EBS, Oracle ERP adapter  etc..)
• Non Oracle Adapter(Salesforce, Ariba, Concur etc..)
• Technology Adapter(REST, SOAP, FTP etc..)

3. What is file Transfer pattern?

Ans: File Transfer pattern allows to move files across network seamlessly and securely. This is again a scheduled type of pattern.

4. What is basic Routing Pattern?

Ans: Basic Routing pattern can connect only two applications with no logic

5. What is lookup in Oracle Integration Cloud?

Ans: Lookups are associate values used by one application for a specific field to the values used by other applications for the same field. This provides the capability to map values across vocabularies or system.

For example, source application uses country code to represent country however target application uses country name to represent country. These mapping can be maintained using Lookup and will be referred by Integration during runtime.

6. Oracle Integration cloud comes under which category of the cloud?  

Oracle Integration Cloud is a platform as a service (Paas)

7. What is Integration in Oracle Integration Cloud?  

Integration is the main ingredient of Oracle Integration; An Integration includes trigger (source) connection and invoke (target) connection and the field mapping between those two connections.

8. What Is Cloud Computing Architecture?

Cloud computing architecture refers to the components and sub components required for cloud computing. These components typically consist of a front end platform (fat client, thin client, mobile device), back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Inter-cloud). Combined, these components make up cloud computing architecture.

9. What is an adaptor in Oracle Integration Cloud?  

Oracle Integration Cloud (OIC) Adaptor is an abstract way to connect to any application with the help of a box adapter. There is 50+ adapters available in OIC, below are the categories

• Oracle Adapter (Oracle Sales Cloud, Oracle EBS, Oracle ERP adapter, etc.)

• Non-Oracle Adapter (Salesforce, Ariba, Concur, etc.)

• Technology Adapter (REST, SOAP, FTP, etc.)

How many design patterns are available in OIC and what are those?

There are total of Six Patterns in Oracle Integration Cloud

• App Driven Orchestration

• Scheduled Orchestration

• File Transfer

• Basic Routing

• Publish To OIC

• Subscribe To OIC

10. What Is Daas In Cloud Computing Architecture?

• Development as a service is web based, community shared development tools. This is the equivalent to locally installed development tools in the traditional (non-cloud computing) delivery of development tools.

Explain What Are The Characteristics Of Cloud Architecture That Separates It From Traditional One?

The characteristics that makes cloud architecture above traditional architecture is:

o According to the demand cloud architecture provides the hardware requirement

o Cloud architecture is capable of scaling the resource on demand

o Cloud architecture is capable of managing and handling dynamic workloads without failure.

11. What is App Driven Orchestration pattern?  

App Driven Orchestration pattern is the multi-step pattern, allows invoking multiple applications in a single flow, doing a for-each loop, if-else logic, apply complex logic, etc.

12. What Is Zero Client?

The zero or ultra-thin client initializes the network to gather required configuration files that then tell it where its OS binaries are stored. The entire zero client device runs via the network. This creates a single point of failure, in that, if the network goes down, the device is rendered useless.

13. What is mapper?

Ans: A visual mapper is provided that enables you to map fields between applications with different data structures by dragging source fields

14. what is package in Oracle Integration Cloud?

Ans: Package is used to group one or more integration into single structure. The package can be exported from source instance and imported into target instance. All integration which are part of the package will be imported automatically.

15. Difference between ICS and OIC?

Ans: Integration Cloud Service (ICS)

Simplify how you build integration in the cloud. This product lets you connect securely to applications and services both in the cloud and on premises. The infrastructure(cloud management, patching, backup, and restore) is managed by Oracle.

Oracle Integration Cloud (OIC)-

Process Cloud Service(PCS)- A process automation tool used to design, automate and manage business processes in the cloud.

Visual Builder Cloud Service(VBCS)- Allows you to rapidly create and deploy web and mobile applications directly from the browser with minimal coding required.

16. How many design patterns are available in OIC and what are those?

Ans: There are total Six Patterns in Oracle Integration Cloud

1. App Driven Orchestration

2. Scheduled Orchestration

3. File Transfer

4. Basic Routing

5. Publish To OIC

6. Subscribe To OIC

17. What is App Driven Orchestration pattern?

App Driven Orchestration pattern is multi step pattern, allows invoking multiple applications in single flow, doing for-each loop, if-else logic, apply complex logic etc.

18. What is Scheduled Orchestration Pattern?

Ans: Scheduled Orchestration pattern allows you to develop an integration which can run on pre-defined frequency and can be executed on adhoc basis.

19. What is File Transfer Pattern?

Ans: File Transfer pattern allows to move files across network seamlessly and securely. This is again a scheduled type of pattern.

20. What is Basic Routing Pattern?

Ans: Basic Routing pattern can connect only two applications with no logic

21. What is publish to OIC and Subscribe to OIC pattern?

Ans: Publish to OIC pattern allows to publish messages to OIC internal messaging queues. For example an event is subscribed from Oracle Sales Cloud and Publish the same into Oracle Integration Cloud messaging queue.

Subscribe To OIC pattern subscribe messages from Oracle Integration Cloud messaging queue and sends the same to different applications

These queue are managed by OIC itself and you don’t have access of them.
