In this post we have prepared Oracle OAF Interview Questions for both experienced and fresh graduates, and we are sharing the Most Important OAF Interview Questions that are frequently asked in interviews. To the best of my ability, I’ve attempted to answer these questions. For your preparations, you can use this list of interview questions.
(Q1) What is Entity Object (EO)?
Ans: EO stands for entity objects, Business logic and rules are encapsulated in EO. Inserting, updating, and deleting data is done with EOs. This is used for cross-application validation. We may also construct an Association entity by linking to other EOs.
(Q2) What is View Object (VO)?
Ans: The database query is encoded in the View object. It’s used for data selection. It allows you to iterate over a set of question results. The majority of VOs are focused on Eos. If the UI is for the upgrade, it can be used on several EOs. It allows you to get and set entity object values from a single location. It can be connected to create View Links.
(Q3) What is Application Module (AM)?
Ans: A container that provides or manages access to the BC4J model object is known as a ‘application module’. On the Application list, the Application module has full power. The Application module is required to run an OAF page. Without the AM, we can’t reach any of the Page’s items.
(Q4) What is Controller (CO)?
Ans: The ‘Controller’ responds to user input and keeps the application flowing. There are two Blocks in the Controller. The controller is where we write our business logic. It helps in the validation and implementation of our business logic.
(Q5) What are the methods available in Controller (CO)?
Ans: Following methods are available in Oracle Controller (CO):
- Process Request: The process request will be fired when the page loads. Put this under Process Request if we want to set any default values when the page loads.
- Process Form Request: Process form request was executed when we pressed the button. So, if we want to run any code after the user presses the Submit button, we’ll place it underneath this block.
(Q6) What is OAF page personalization?
Ans: Oracle Apps Framework has an OA Personalization Framework that allows you to customize every OAF page in an Oracle E-business Suite application without modifying the page’s basic or underlying code. Oracle Application Framework makes it simple to modify the layout of a page, as well as the personalization of data displayed on an OA Framework page.
(Q7) What is BC4J in Oracle OAF?
Ans: JDeveloper’s Business Components for Java programming environment allows you to build multi-tier database frameworks using reusable business components. The following are common components of these applications:
- Java and/or HTML are used to build a client-side user interface.
- Business logic and views of business objects are provided by one or more business logic tier elements.
- The underlying data is stored in tables on the database server.
(Q8) What are the steps required for VO extension in Oracle OAF?
Ans: Following steps are required to extend any View Object(VO) in Oracle OAF:
- Determine which VOs you need to extend.
- Save the VO to your local desktop in the ‘My Projects’ folder of your JDevloper setup from the Oracle Java Top Location.
- After that, you need to construct a New ‘View Object’ (VO) that is an extension of the Standard View Object.
- The Standard View Object is then used in place of the New Custom View Object.
- The New Custom View Object is then uploaded to the Oracle Java Top Location.
- Then use the XML Importer script to register the new ‘View Object’ in the Oracle application.
- After Import/Registration, you add a new field to the OAF page via Personalization and then reference the New Custom ‘View Object’ in this Field (VO).
(Q9) What is message file upload in Oracle OAF?
Ans: One of the Item properties in the OAF pages is Message File Upload. ‘MessageFileUpload’ is a built-in property that allows you to build a File Upload Option in the OAF page and upload files to the Oracle Apps server.
(Q10) What is RootAM in Oracle OAF?
Ans: The root application module is the one that is aligned with the top-level page area (the PageLayout region).
(Q11) What is Extension in Oracle OAF?
Ans: When you take an existing component, such as an OAF page or a region, and apply new features to it without affecting the original functionality, this is known as extension.
(Q12) What is MDS in Oracle OAF?
Ans: MDS is an acronym for MetaData Service. When a web page is broken down into small pieces, such as buttons and fields, it is saved in a database. This are stored as data in tables rather than as binary files. The information is stored in JDR tables. MDS offers a service for storing and retrieving page definitions. To construct a page, MDS gathers those meanings in meaningful components/fields.
