Oracle Applications :Technical interview preparation part 2

1. What is Concurrent Programming?

Concurrent Processing in Oracle Apps simultaneously executes programs running in the Background with online operations to fully utilize your hardware capacity.

Use Concurrent Programming for

Long Running – Data intensive tasks such as Posting a Journal or generating a report.

2. What is the Role of Concurrent Managers?

A Concurrent Manager is a component of Concurrent processing that monitors and runs tasks without tying up your computer.

3. What is AOL?

Oracle Applications are constructed and maintained using the Application Object Library (AOL).

The Three main areas of AOL are

• Applications Security
• Operating Profile
• Concurrent Processing
3. Define Interfaces. What are the different types of Interfaces?

Interfaces are used to integrate external systems and data conversion in Oracle Applications.

These can be used to either transfer data from Oracle Applications to a Flat File or Data from Legacy System to Oracle Applications.

There are two types of Interfaces. Inbound and Outbound Interfaces.

Inbound Interfaces are used to transfer data from external system to Oracle Applications.

Outbound Interfaces are used to transfer data from Oracle Applications to External System.

Open Interface is the interface whose interface logic is provided by Oracle.

Custom Interface is an Interface whose logic is developed by implementation team.
