The Oracle Forms Builder is an Integrated Development Environment (IDE) included in the Oracle Developer Suite package. It is intended for Rapid Application Deployment (RAD) using PL/SQL.

What are the steps you have to follow to register a Form?
·         We will down load template.fmb from AU_TOP ($AU_TOP/forms/US) resource folder. Then we will delete block name from window, datablock, canvas.
·          Change the property class for window, canvas and data block.
·         Change the name of form.
·         Go to pre_form trigger at form level. Give the window name in set window position function. We change action History like date and author name (optional).
·         Go to when _new_form instance at form level give the form name in template.fmb place
·         Go to program units select app_custom package body in the following function.
If (wnd = 'window name') then app_window.close_first_window;
·         Compile the form and save. It will create FMB and create the fmx by following option.
 File => administration => compile file.
·         move the fmb to au_top=>11.5.0=>forms=>us
·         move the fmx to the corresponding to PO => 11.5 => forms => us
·          Select  the responsibility  called application developer
First create the form by using following navigation application => form                                                                                                                       give the name of fmx in form field. Give the application name where the fmx is stored. We can give our own user form name select the user form name goto function we will create the function, user function name                                                               select properties tab and choose the type as form And goto form tab give the user form name in the form field
·         Go to menu option will attach the function to the menu
·         We will attach the menu to the resp through sysadmin.

How do you generate Apps Forms modules or FMB files?
Oftentimes as part of upgrading Forms or modifying a Form module or applying a patch modifying a Form module, you would encounter an issue that would necessitate manually regenerating the Forms module executable or FMX file. To do this you issue the following command:  f60gen module=form_name.fmb userid=apps/apps output_file=form_name.fmx module_type=form batch=yes compile_all=special

How do you generate Apps Forms library modules or PLL files?
To do this you issue the following command: f60gen module=library_name.pll userid=apps/apps module_type=library batch=yes compile_all=special

Write the Abbreviation for the following File Extension?
1. FMB – Form Module Binary
2. MMB -- Menu Module Binary
3. PLL—PL/SQL Library Module Binary

What is ZOOM? How it works?
Zoom is a function provided by apps which can be used to call another form from a form. For making zoom available for your form u have to customize the custom.pll.  We have to add a branch stating if form name (specify form name) and blockname (specify blockname) then make zoom available.

What are the standard libraries available in template form?
·         FNDSQF(Routines for handling Message Dictionary, flexfields, profiles, concurrent processing, multicurrency, WHO)
·         APPCORE
·          APPCORE2
·         APPDAYPK(Controls the Application Calendar)
·         CUSTOM

What is who column and how you set the values?

The custom form requires a pre-insert trigger at the block level containing the FND_STANDARD.SET_WHO function.  This trigger/function enables the 'About This Record' info and displays the info for the User when requested.

Name the directory having the FORMS source codes (FMB files)?
The FORMS source codes having the directory $AU_TOP/forms/US

Can we change the profile value? How?
Fnd_profile API can be used to set the profile value
fnd_profile.put (name in varchar2, value in varchar2).

What are the steps  you have to follow to register a custom application?
·         Register custom application in AOl
·         create a physical director structure under APPL_TOP
·         modify the environment file to include custom schema path
·         in the backend register the custom schema as user
·         register the user with AOl
·         add the custom schema to standard data group
·         register all the custom table with the application
·         create synonyms in apps schema for custom objects

What is event handler package?
An event handler is a PL/SQL procedure that encapsulate all the code that act upon an event. Usually we will use to satisfy the requirement of Oracle forms or oracle application interface standard for form base product.

Can we modify all the triggers?
No. There are some triggers which should not be modified. Here are the form triggers that must not be changed

When you are moving a cursor on a form what are the possible triggers that are going to be fired?
If you are moving from an item of first block to the item of another block in a form then following trigger will be fired.
when-validate-item (fired only when the status of the text item has been changed)

If you are moving from an item to another item in same form then following trigger will be fired.
