ODI Interview Questions and Answers

Oracle Data Integrator Interview Questions and Answers can assist you in meeting your data integration goal with an easy, user-friendly interface that enables you to develop, manage, and monitor integration processes easily.

Integration technologies like ETL, data warehousing and big data platforms are supported.

1. What is Topology security in the context of project management?

Topology security refers to an administrative role undertaken by senior personnel working on a project accountable for maintaining data server configuration and creating security user accounts.

2. What are some of the policy settings that are included in Topology security?

Topology security’s policy settings include additional agents with features and technologies suited for cloud environments like Amazon Red shift and HVFS High that enhance extensive data management and cloud usage.

3. What does an agent do in Topology security?

An agent in Topology security takes source code from jobs, identifies technologies involved and transfers them to specific sources or targets.

4. What features does J2 derivation offer?

J2 derivations offer middle-tier features, such as high availability, load-balancing clustering and additional web logic features.

5. What is the purpose of context in data management?

Data management contexts serve as environments or server groups in data storage environments such as development or production environments.

6. What is the logical schema in data architecture?

Logical architecture refers to the physical schema in data architecture; developers use these logical names to interface with data service services that use physical architecture.

7. What is hierarchical execution in the load plan?

Hierarchical execution in a load plan refers to a feature that allows scenarios to be executed hierarchically; however, its practical use cannot be guaranteed as users must use scenarios directly within their load plans instead.

8. What is the advantage of using load plans over packages?

Load plans provide additional features like restarting on failure state, task and all children which makes a distinct difference from packages.

9. What is the loading knowledge model, and when is it used?

A Load knowledge model verifies knowledge models when enabled via flow controllers, only utilised when such access points become active.

10. What is static control, and when can it be used?

Static control is a method that detects invalid data before loading it to target tables suppose no restrictions limit how it should be loaded, it is typically used if constraints do not limit target table use.

11. What are recycler rates, and how can they be used?

Recycler rates are an integral component of data reuse, which allows recycling or building up data from one table into another and deleting all or specific records if one table fails.

12. What is the process of creating a target table?

To create a target table, the process begins at the model level first using generalisation knowledge modelling, which makes a consistent series of data from different tables into a straightforward format for table presentation.

13. How can organisations streamline their data capture and management processes?

They may do this by adopting the generalisation knowledge model and activating the CDC process.

14. What is the role of the knowledge model in the CDC?

A knowledge model in the CDC allows behaviours such as rapid critical analysis of inaccessible objects, history-keeping and tracking recent changes based on flagged events.

15. How can users manage data in the CDC?

Users may manage data in the CDC using different knowledge models and performing various operations like loading, selecting, and evaluating data.

16. How can users track progress in the CDC?

Users can monitor progress using packages and folders to display development status updates.

17. What is the purpose of assigning the status of the algorithm and object in the development of objects?

Attributing status to algorithms and objects permits variable log-in and repetitive progress; this approach can prove particularly valuable when working on significant Mars-related leads.

18. What is the Oracle Data Indicator Studio?

Oracle Data Indicator Studio is an architectural tool for Oracle applications’ physical and logical architectural design.

19. What is the designer operator?

A designer operator is part of Oracle data indicators’ topology manager team, responsible for overseeing project activities under its supervision, such as developing plans, committing models, and designing interfaces; theyare integral to development work on projects under development.

20. What is the agent?

Oracle data indicators’ topology manager includes an agent to monitor interfaces and handle scheduled events through Aliens, this agent performs many duties to facilitate optimal operation.

21. What is the purpose of Oracle data indicators?

Oracle data indicators are vital when developing practical applications; developers can design user-friendly and empirical applications by understanding these components.

22. What are the repositories in ODI?

Open Data Integration uses two repositories in its process – master and work repositories – the former serving as its first creation step. At the same time,the latter contains information regarding data models, projects and users.

23. What is an Oracle Data Indicator?

An Oracle Data Indicator is a database management system that offers a structured data structure for monitoring IT resources within companies and managing security and versioning objects of data models.

24. What does a package do in a developer’s work?

Packages give developersa more leisurely development experience by turning a multiple-step process into one check executable.

25. What are the log levels in ODI?

It offers various log levels, including notification, incident error warning traceback, high priority, and log data test logging levels.

26. What are the two types of sequences in ODI?

ODI supports two kinds of sequences – standard ones are stored within its repository, while specific sequences reside externally within relational database management systems.

27. What are the execution units in Oracle Data Integrator?

Execution units correspond to procedure commands within knowledge modules in Oracle Data Integrator, used for assigning first-year variables or performing other tasks.

28. What is the ODI console?

An ODI Console is a web desk navigator that enables users to quickly and conveniently access designer operators and topology navigators within Oracle Data Integrator browser interfaces.

29. How can users create sub-queries in ODI?

Users can easily create sub-queries in ODI using its yellow interface and sub-query option, views created using an ODI procedure or direct database queries, and more.

To test yourself on what you have learned, use multiple-choice exams.

30. What is the primary role of topology security in ODA?

Identifying technologies and transferring them to specific sources and targets

Maintaining data server configuration and security user creation

Tracking logs related to the job

Creating metadata repositories in operators

31. What are the two options for performance implementation in planning?

RFH size and batch update size.

Database size and software version.

Server capacity and network speed.

Hardware configuration and power supply.

32. Which of the following is a crucial aspect of data management?

Creating a data service

Managing connections and data resources

Connecting the logical schema to the context

Associating the physical schema with the physical schema

33. What is the additional feature in mapping the logical schema that allows for automation purposes like auditing?

“After starting over mapping”

“Before starting over mapping”

“Parallel jobs generate the same download tables.”

“Creating unique temporary object names.”

34. What is the loading knowledge model used for?

Checking the knowledge model

Identifying duplicate or null data

Loading data into the target table

To recycle or build up data from the target table to the data table
