Examples of how to answer interview questions about Oracle Apps DBA
Here are some sample questions and answers about Oracle Apps that can help you get ready for a DBA interview:
1. What is the architecture of Oracle Apps?
Most of the time, employers ask this kind of question to see how much experience you have with Oracle. Oracle’s architecture describes how it is made. Most programmers who work with Oracle should know this. Most of the time, the hiring manager wants to know if you are a good programmer and know how to use this program. Most of the time, interviewers want to hear a brief explanation of Oracle’s three main tiers. Write down each level and what it does.
Example: “The architecture of Oracle Apps DBA is made up of three main parts: the database, the middle, and the desktop. Part of the database tier is the relational database management system (RDBMS) database, which is the Oracle database server. In Oracle, the database tier is where programmers store all the data they need to use. On the middle tier, there are several servers, such as web, admin, and report servers. Last, the desktop tier is where the client desktop is. Users can go here to use Oracle applications in their browsers.”
Why do you need a guest account to link to a database?
This question is another way to find out how much you know about Oracle Apps. The question is more specific and asks why you need this account to do something. After asking you some basic questions about Oracle, hiring managers usually move on to more difficult questions. This is to make sure you are qualified for the job and can meet its needs. To answer this question, start by explaining why you might want to make an Oracle guest account. After you do this, explain in more detail how a guest account can be used to connect to a database.
Example: “The guest user account is for an application user, so programmers need to make their own guest accounts on Oracle. This is done so that you can figure out the APPS password, which is usually encrypted. Once you make a guest account, you get the decrypted value of the app’s password, which lets you do things like connect apps.”
3. Explain how you would get rid of a responsibility in Oracle Apps.
An employer might ask you this question at an interview to see how well you know Oracle Apps. You tell how to do something in this program to answer this question. In other questions, you might be asked to explain what something is or how important it is in Oracle. On the other hand, this question gives you a chance to show what you can do as a DBA. Most of the time, the hiring manager wants a clear answer that explains what a responsibility is and gives a few ways to get rid of one.
Example: “In Oracle, a user’s level of power determines how responsible they are. When users have this level of access, they can use special Oracle features like data, forms, and menus. Oracle has a way to track which users are in charge of something and for how long. By giving a responsibility an end date in the records system, you can get rid of it. Users can get rid of a task with backend and frontend programming.”
4. What is a global inventory and a local inventory?
In this second technical question, you have to describe two parts of Oracle. Employers might ask you this because inventories are an important part of using this database program. Oracle has a lot of complicated systems and processes, so hiring managers want to make sure you know how to use it well. Explain in detail what the global and local inventories are in your answer. Also, try to explain why you would use each item.
Example: “The XML inventory, which is a list of all the Oracle products you have on a device, includes the Global inventory. This means that there is only one Global Inventory for each device. This inventory also keeps track of where each item is, but it doesn’t store specific information about each item. You can make changes to the Global inventory by putting Oracle on the device.”
5. How do I make a schema of my own?
In Oracle, schemas are used by DBAs to store and organize database objects. Schemas are an important part of this system, which is why most employers ask this question. They could also ask this to see how much you know about Oracle. This question asks you to list more than one step to complete a task, which lets you show off your skills. Since there are nine steps to this process, try to keep your explanation short and simple. Don’t forget to say these steps to show how much you know.
Example: “To make a custom schema in Oracle, you need to follow nine steps. First, make a tablespace in the database on the back end. After that, you can make a schema that grants and resources can use to connect to. The fourth step is to set up how your custom files are organized in directories. Then, make a custom environment in your directory.
Next, register your Oracle schema by logging into Applications and finding “Register” on the “Application” menu. The seventh step is to add an application to a data group and register an Oracle user. The ninth step is to add your custom request group, menu, and other features to your custom schema.”
