1. What is Workflow?
In the competitive world Business Process today Involve getting many type of
information to multiple people …. Accordingly to rules that are constantly changing …..
oracle workflow let you automate and continuously improve the business process.
To do this oracle provide us with a tool called as Oracle Workflow Builder
What is this Tool Oracle Workflow Builder?
Oracle Workflow Builder is a graphical tool for creating, viewing, and modifying
workflow process definitions. It contains a Navigator window and the Process window
Before we talk about the navigation window and the process window lets us talk about
the major future and definition of Oracle Workflow
The Major Future of Oracle Workflow are
1. ORACLE WORKFLOW BUILDER.
2. ORACLE WORKFLOW ENGIN
3. WORKFLOW DEFINATION LODADER
4. COMPLETE PROGAMMATIC EXTENSIBILITY
5. ELECTRONIC NOTIFICATIONS
6. ELECTRONIC MAIL INTEGRATION
7. INTERNET ENABLE WORKFLOW
We do have oracle workflow architecture.
Let us not defined this as a developer we should have the knowledge of it and
what so it does. U can go through the User or Developer Guide for the definition.
What does this Process Window and Navigation Window of Oracle Workflow
Builder Tool Contain?
So to define the workflow process oracle workflow builder provide us with some
components and activity Process. Navigation window contain all this components
/activity/Process.
These components activity process are dreg from Navigation window to the process
window and are assembled to form the process diagram.
Know we can define workflow as ….the process diagram (or the process) that is
created by activities / Components Depending upon our business flow. (Using
Oracle Workflow builder tool)

2. Note: Oracle workflow builder tool comes as Standalone workflow builder and
Embedded version of workflow.
So let us not talk about the version …..
We have some idea of what is workflow and Workflow builder so let us define
What is Process , Activity and Components
process Depending upon the business requirement and the process or the Business Flow
how the business to be driven (requirement) we have to assemble or create the workflow
diagram.(with some components/activity) and this process diagram is refer to as Process.
This process can be broken in to much process or sub process again depends upon the
business requirement.
For example if say we make a LOCAL/STD/ISD call by the time it get connected to the
no we have called we can make this as a single process or many process or the sub
process.
Activities An activity is a unit of work that contributes toward (the accomplishment) to
complete the process.
An activity can be a notification, a function, or a process.
A function activity calls a PL/SQL stored procedure or some external program to
perform an automated function. (Note Function will have input parameter and
result paremater--- these parameter are nothing but attributes)
A process activity is a modelled workflow process, which can be included as an
activity in another process to represent a sub–process.
A notification activity sends a message or information to a workflow user. The
message may simply provide the user with information or request the user to take
some action.
Components Can be the message and attribute.
***********************************************************************
Item Type Activity + components with Process saved as Item Type.
Activities Components
Notification Message
Function/Procedure Attributes
Process
Lookup Type and Roles (Users)

3. So when u defined the workflow (i.e when we assemble the components and activities
to from the workflow u may use some standard result type as Boolean (Yes /No
,Approve /Reject ..etc ) these can be defined as Lookup types.
Oracle workflow defined some standard activities and lookup types they are
And/Or Activities
Comparison Activities
Compare Execution Time Activity
Wait Activity
Block Activity
Defer Thread Activity
Launch Process Activity
Noop Activity
Loop Counter Activity
Start Activity
End Activity
Role Resolution Activity
Notify Activity
Vote Yes/No Activity
Master/Detail Coordination Activities
Wait for Flow Activity
Continue Flow Activity
Assign Activity
Get Monitor URL Activity
Concurrent Manager Standard Activities
Execute Concurrent Program Activity
Submit Concurrent Program Activity
Wait for Concurrent Program Activity
Default Error Process
We do have some standard error process and activities you can use to create a
custom error process. You can assign an error process to a process
activity. If an error occurs, the error process informs Oracle Workflow
how to handle the error. See: Default Error Process.
Suppose say u have to defind the activity say procedure the takes the input/output
parameter that have to be passed when the workflow is lanched. Then we respresent
these parameters as Components. Called as attributes.
Or say u make use of standard activity SetItemUserKey that have 3 input parameter and
the parameter are passed when the workrflow is lunched

4. What are Roles and Users
To know about the roles and users see the link.
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?
p_database_id=FOR&p_id=615685.999
let us not defined the User and the Role . (Role is nothing but group of user’s)
let us assume the we have only the user and proceed further.
So can any one tell me what are the minimum components that are require to
defined the Workflow
One Process
One Start Activity
One End Activity
One User

5. So what is the importance of workflow?

7. Creating the Process

8. Creating Function

9. CREATE OR REPLACE PACKAGE body wf_emp_lev
AS
PROCEDURE validate_emp(itemtype in varchar2,
itemkey in varchar2,
actid in number,
funcmode in varchar2,
resultout out varchar2)
AS
l_eno number;
l_eno_id number;
l_days number;
begin
l_eno := wf_engine.GetItemAttrNumber (itemtype => itemtype,
itemkey => itemkey,
aname => 'EMP_ID');
l_days := wf_engine.GetItemAttrNumber (itemtype => itemtype,
itemkey => itemkey,
aname => 'DAYS');
--Validates the empno
select empno
into l_eno_id
from emp
where empno =l_eno;
--Update the lev_days
update emp
set lev_days = l_days
where empno = l_eno;

10. resultout:='T';
return ;
exception
when others then
resultout:='F';
return;
end validate_emp;
end wf_emp_lev;
/
launching the Workflow through API
Attaching the workflow to a form
If the API is written in the form the we can see the in the
menu TOOLSWORKFLOW STATUS the status of work flow
(there may be some profile setting that we may have to see)
