Defining Data Groups
This essay explains how you can define data groups, which specify your applications database connections.
Introduction to Data Groups
A data group is a list of Oracle Applications and the Oracle username assigned to each application. Each application in a data group must have a Oracle username assigned to it. An application may be listed only once in a data group.
An Oracle username and password allow access to an application's tables in an Oracle database. Each Oracle username in a data group determines the database tables and table privileges accessible by the corresponding application or applications.
Figure 1 - 8.
Data Group's Purpose
Each responsibility has a data group associated with it. A data group serves two purposes:
1. It identifies the Oracle username that forms connect to when you select the responsibility.
2. Concurrent managers use a data group to match the application that owns a report or concurrent program (submitted by a user of the responsibility) with a Oracle username.
Remarks on Data Group's structure
There are four points concerning the makeup of any Data Group.
1. Within each data group, an application can be listed only one time.
2. Within each data group, an Oracle username can be paired with more than one application.
3. Within each data group, the application Application Object Library is automatically included.
- Application Object Library's Oracle username cannot be updated or deleted.
- Application Object Library owns the database tables that oversee concurrent processing and the standard submission of reports by any Oracle Application.
4. Within each data group, a Tool Oracle username can be associated with each application-Oracle username pair. If that application-Oracle username pair is chosen as the one for forms to connect to when the responsibility is selected, then the Tool Oracle username is relevant, and appears by default.
Attention: To prevent users of a responsibility from connecting to the database using a Tool Oracle username, you can backspace over (erase) the default entry. You cannot select a Tool Oracle username associated with another application in the data group.
The Tool Oracle username identifies the database tables and privileges a user of the responsibility has when connecting to the database using an Oracle Tool, for example, SQL*Plus.
- When users of the responsibility select Oracle Tools window to run a tool that requires a database connection, the Tool Oracle Username appears as the default tool access Oracle Username.
- Users do not need to enter an Oracle password to use the Oracle Username.
Attention: The Oracle Tools window may not be available on your desktop platform.
Warning: If the Oracle Tool is query-only, for example, Oracle Browser, you may assign an unrestricted Tool Oracle Username. If the Oracle Tool allows write privileges, you should assign a Tool Oracle Username that is restricted (read-only).
Warning: Modifying data or table structures using an Oracle Tool, for example, SQL*Plus or SQL*Forms, may damage your data's integrity and is not supported by Oracle.
