Creating a custom application in Oracle Apps

Custom Applications are required if you are creating new forms, reports, etc.This allows you to segregate your custom written code from the standard seeded functionalitythat Oracle Applications provide.

Customizations can therefore be preserved when applying patches or upgrades to yourenvironment.

Lets go a head and create a custom application and its related elements.

Following are the elements to be created:

SCHEMA NAME : XXERP

TOP NAME : XXERP_TOP

Application : XXERP Custom Application

Data Group : Standard

Request Group : XXERP Request Group

Menu : XXERP_CUSTOM_MENU

Responsibility : XXERP Custom

Assumptions:

APPL_TOP: /d01/oracle/PROD/apps/apps_st/appl

Instance Name: PROD

Server Name: blrrdebs2

1) Make the directory structure for your custom application files.

cd $APPL_TOP

mkdir XXERP

mkdir XXERP/12.0.0

mkdir XXERP/12.0.0/admin

mkdir XXERP/12.0.0/admin/sql

mkdir XXERP/12.0.0/admin/odf

mkdir XXERP/12.0.0/sql

mkdir XXERP/12.0.0/bin

mkdir XXERP/12.0.0/reports

mkdir XXERP/12.0.0/reports/US

mkdir XXERP/12.0.0/forms

mkdir XXERP/12.0.0/forms/US

mkdir XXERP/12.0.0/lib

mkdir XXERP/12.0.0/out

mkdir XXERP/12.0.0/log

2) Add the custom module into the environment

You can see three environment files..

APPSPROD_blrrdebs2.env --> Control file

customPROD_blrrdebs2.env --> Custom environment variables file

PROD_blrrdebs2.env --> All seeded environment variables file

Perform the actions below:

cd $APPL_TOP

echo "XXERP_TOP=/d01/oracle/PROD/apps/apps_st/appl/XXERP/12.0.0" >

customPROD_blrrdebs2.env

echo "export XXERP_TOP " >> customPROD_blrrdebs2.env

above commands will add our module's environemnt settings.

APPSPROD_blrrdebs2.env file should read as..

customfile=/d01/oracle/PROD/apps/apps_st/appl/customPROD_blrrdebs2.env

if [ -f $customfile ]; then

. /d01/oracle/PROD/apps/apps_st/appl/customPROD_blrrdebs2.env

fi

. /d01/oracle/PROD/inst/apps/PROD_blrrdebs2/ora/10.1.2/PROD_blrrdebs2.env

. /d01/oracle/PROD/apps/apps_st/appl/PROD_blrrdebs2.env

Make the following entry to the application context file - PROD_blrrdebs2.xml (marked in red)

vi $INST_TOP/appl/admin/ PROD_blrrdebs2.xml

oa_enabled="FALSE">/d01/oracle/PROD/apps/apps_st/appl/au/12.0.0

oa_enabled="FALSE">/d01/oracle/PROD/apps/apps_st/appl/XXERP/12.0.0

OP>

Generate new top by using adgentopfile.sh

cd $INST_TOP/admin/install

sh adgentopfile.sh

Itll add a new entry in topfile.sh ($APPL_TOP/admin/ topfile . txt)

XXERP /d01/oracle/PROD/apps/apps_st/appl

3) Create new tablespace for database objects

Login as system/manager into sqlplus and execute the following command:

create tablespace XXERP datafile /d01/oracle/PROD/db/apps_st/data/XXERP01.dbf' size 500M;

4) Create a Database user and assign roles (Schema gets created automatically)

create user XXERP identified by XXERP

default tablespace XXERP

temporary tablespace temp

quota unlimited on XXERP;

grant connect, resource to XXERP;

5) Register your custom application into APPS

Login to Applications with System Administrator responsibility

Navigate to Application-->Register

Application = XXERP Custom Application

Short Name = XXERP

Basepath = XXERP_TOP

Description = XXERP Custom Application

6) Register your custom User into APPS

Naviate to Security-->Oracle-->Register

Database User Name = XXERP

Password = XXERP

Privilege = Enabled

Install Group = 0

Description = XXERP Custom Application User

7) Create a new datagroup and add our application to it (along with all seeded)

Navigate to Security-->Oracle-->DataGroup

Data Group = XXERPGroupDescription = XXERP Custom Data Group

Click on "Copy Applications from" and pick Standard data Group, then add the following entry.

Application = XXERP Custom ApplicationOracle ID = APPSDescription = XXERP Custom Application

8) Create custom request group

This will act as a placeholder for any custom reports we wish to make available for the CustomResponsibility (which is defined at a later stage)

Navigate to Security-->responsibility-->Request

Group = XXERP Request Group

Application = XXERP Custom

Code = XXERP

Description = XXERP Custom Requests

We will not define any requests to add to the group at this stage, but you can add some now ifrequired.

9) Create custom menu

This will act as a placeholder for any menu items we wish to make available for the CustomResponsibility (which is defined at a later stage).

Navigate to Application-->Menu

Menu = XXERP_CUSTOM_MENU

User Menu Name = XXERP Custom Application

Menu Type =

Description = XXERP 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

10) Create new responsibility.

Navigate to Security-->Responsibility-->Define

Responsibility Name = XXERP Custom

Application = XXERP Custom

Responsibility Key = XXERPCUSTOM

Description = XXERP Custom Responsibility

Available From = Oracle Applications

Data Group Name = XXERPGroup

Data Group Application = XXERP Custom

Menu = XXERP Custom Application

Request Group Name = XXERP Request Group

You are now ready to create your database Objects, custom Reports, Forms, Packages etc.,

Create the source code files in the XXERP_TOP directory appropriate for the type of object. Forexample forms would be located in $XXERP_TOP/forms/US or package source code in$XXERP_TOP/admin/sql for example.

Database Objects such as tables, indexes and sequences should be created in the XXERPschema, then you need toa) Grant all privilege from each custom data object to the APPS schema.For example : logged in as XXERP usergrant all privileges on myTable to apps;

b) Create a synonym in APPS for each custom data objectFor example : logged in as APPS usercreate synonym myTable for XXERP.myTable;

Other database objects such as views and packages should be created directly in the APPSschema.

Creating a custom applicaiton is the first and foremost thing a Technical consultant / DBA doesbefore creating any new object. Kindly provide your feedback to make this article better.
