Creating a Custom Application in Oracle Apps

Creating a Custom Application in Applications 11i

Custom Applications are required if you are creating new forms, reports, etc. This allows you to segregate your custom written files from the standard seeded functionality that Oracle Applications provide. Customizations can therefore be preserved when applying patches or upgrades to your environment.

1.                 Make the directory structure for your custom application files

cd $APPL_TOP
mkdir xxmz
mkdir xxmz/11.5.0
mkdir xxmz/11.5.0/admin
mkdir xxmz/11.5.0/admin/sql
mkdir xxmz/11.5.0/admin/odf
mkdir xxmz/11.5.0/sql
mkdir xxmz/11.5.0/bin
mkdir xxmz/11.5.0/reports
mkdir xxmz/11.5.0/reports/US
mkdir xxmz/11.5.0/forms
mkdir xxmz/11.5.0/forms/US
mkdir xxmz/11.5.0/$APPLLIB
mkdir xxmz/11.5.0/$APPLOUT
mkdir xxmz/11.5.0/$APPLLOG

2.                 Add the custom module into the environment

Apply ADX.E.1 and add the entry to topfile.txt as a standard product top entry (follow the existing model in the file) Customised environment variables can be added to AutoConfig by using the filename specificed by s_custom_file, which is then called from the APPSORA.env file. If using Forms Listener Servlet, you may also need to add $CUSTOM_TOP to formsservlet.ini in $APACHE_TOP/Jserv/etc

3.                 Create new tablespace for database objects

create tablespace xxmz datafile '/emea/oracle/visuk09/visuk09data/xxmz.dbf' size 10M default storage(initial 10k next 10k)

4.                 Create schema

create user xxmz identified by xxmz
default tablespace xxmz
temporary tablespace temp
quota unlimited on xxmz
quota unlimited on temp;
grant connect, resource to xxmz;

5.                 Register your Oracle Schema.

Login to Applications with System Administrator responsibility
Navigate to Application-->Register
Application = xxmz Custom
Short Name = xxmz
Basepath = xxmz_TOP
Description = xxmz Custom Application

6.                 Register Oracle User

Navigate to Security-->Oracle-->Register
Database User Name = xxmz
Password = xxmz
Privilege = Enabled
Install Group = 0
Description = xxmz Custom Application User

7.                 Add Application to a Data Group

Navigate to Security-->Oracle-->DataGroup
Data Group = xxmzGroup
Description = xxmz Custom Data Group
Click on "Copy Applications from" and pick Standard data Group, then add the following entry.
Application = xxmz Custom
Oracle ID = APPS
Description = xxmz Custom Application

8.                 Create custom request group

This will act as a placeholder for any custom reports we wish to make available for the Custom Responsibility (which is defined at a later stage)
Navigate to Security-->responsibility-->Request
Group = xxmz Request Group
Application = xxmz Custom
Code = xxmz
Description = xxmz Custom Requests
We will not define any requests to add to the group at this stage, but you can add some now if required.

9.                 Create custom menu

This will act as a placeholder for any menu items we wish to make available for the Custom Responsibility (which is defined at a later stage) We will create two menus, one for Core Applications and one for Self Service.
Navigate to Application-->Menu
Menu = xxmz_CUSTOM_MENU
User Menu Name = xxmz Custom Application
Menu Type =
Description = xxmz Custom Application Menu
Seq = 100
Prompt = View Requests
Submenu =
Function = View All Concurrent Requests
Description = View Requests

Seq = 110
Prompt = Run Requests
Submenu =
Function = Requests: Submit
Description = Submit Requests

Menu = xxmz_CUSTOM_MENU_SSWA
User Menu Name = xxmz Custom Application SSWA
Menu Type =
Description = xxmz Custom Application Menu for SSWA

10.             Create new responsibility. One for Core Applications and One for Self Service (SSWA)

Navigate to Security-->Responsibility-->Define
Responsibility Name = xxmz Custom
Application = xxmz Custom
Responsibility Key = xxmzCUSTOM
Description = xxmz Custom Responsibility
Available From = Oracle Applications
Data Group Name = xxmzGroup
Data Group Application = xxmz Custom
Menu = xxmz Custom Application
Request Group Name = xxmz Request Group

Responsibility Name = xxmz Custom SSWA
Application = xxmz Custom
Responsibility Key = xxmzCUSTOMSSWA
Description = xxmz Custom Responsibility SSWA
Available From = Oracle Self Service Web Applications
Data Group Name = xxmzGroup
Data Group Application = xxmz Custom
Menu = xxmz Custom Application SSWA
Request Group Name = xxmz Request Group

11.             Add responsibility to user

Navigate to Security-->User-->Define
Add xxmz Custom responsibility to users as required.

12.             Other considerations

You are now ready to create your database Objects, custom Reports, Forms, Packages, etc
Create the source code files in the xxmz_TOP directory appropriate for the type of object. For example forms would be located in $xxmz_TOP/forms/US or package source code in $xxmz_TOP/admin/sql for example.
Database Objects, such as tables, indexes and sequences should be created in the xxmz schema, then you need to

a) Grant all privilege from each custom data object to the APPS schema.

For example: logged in as xxmz user
grant all privileges on myTable to apps;

b) Create a synonym in APPS for each custom data object

For example: logged in as APPS user
create synonym myTable for xxmz.myTable;
Other database objects, such as views and packages should be created directly in the APPS schema.
