Application Object Library (AOL) in Oracle Apps R12

AOL mainly contains three things:

• Operating profiles (System Profiles)
• Application security (User, Function, and Responsibility Security)
• Concurrent Processing (Concurrent manager, request, program, process)

AOL is a powerful library having components of code (objects) used in one or more applications. 

AOL contains the following components:

• Users
• Responsibilities
• Request Group
• Request Sets
• Concurrent Programs
• Concurrent Managers
• Concurrent Program Executables
• Value Sets
• Flex Fields
• Form and Functions
• Menus
• Messages
• Table Registration
• Profiles
• Data Group

Responsibility

• It is nothing but a collection of three things – menu, data group, and request group which is attached to a specific user as per his/her level of access.

Request Group

• A request group is a collection of concurrent programs or request sets. It is attached to a responsibility to control the user’s access to concurrent programs/requests.

Request Set

• A request set is a collection of reports and/or programs that you group together. You can submit the reports and/or programs in a request set all at once using a single transaction.

Concurrent Program

• A concurrent program is a program that does not require continued interaction on your part to perform a specific task. In Oracle Applications, for example, the concurrent program may be a program written to create a report or to post a batch of general ledger journal entries.

Concurrent Manager

• The concurrent manager is a component of concurrent processing that monitors and runs tasks without tying up your computer.

Concurrent Process

• The concurrent process is an instance of a running concurrent program. Each time a concurrent manager receives a request and runs a concurrent program, it creates a new concurrent process. A concurrent process can run simultaneously with other concurrent processes

Concurrent Request

• The concurrent request is a request that you submit to run a concurrent program as a concurrent process.

Value Set

• A set of predefined or validated values assigned to a field (parameter) that restricts the user to enter from entering invalidated data.

Menu

• A  menu is a hierarchical arrangement of functions and menus of functions that appears in the Navigator.
• A  menu entry is a menu component that identifies a function or a menu of functions.
• Each responsibility has a menu assigned to it.

Functions

• A function is a set of Oracle Applications that is executed only if the name of the function is present in a list maintained within a responsibility.
• Because all users should not have access to every business function in a form, Oracle Applications provide the ability to identify pieces of applications logic as functions.
• Function security lets you restrict application functionality to authorized users.

Data Group

• The data group is a collection of pairings of Applications with Oracle ID.
• An Oracle ID is a username and password that allows access to application tables in an Oracle database.
• Concurrent managers use a data group to match the application that owns a report or concurrent program with a unique Oracle ID.
