The document discusses Oracle Workflow Builder and its components. Oracle Workflow Builder is a graphical tool for creating and modifying workflow process definitions. It contains a Navigator window to add activities and components, and a Process window to assemble them into a workflow diagram. Key components of a workflow include processes, activities, and attributes. Processes represent business flows and can contain activities like notifications or functions. Attributes represent input/output parameters of activities.
Workflow demo
- 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? **************************** global setting and configuration of WFMAIL.CFG ******************************************** ********************************************
- 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 TOOLSWORKFLOW STATUS the status of work flow (there may be some profile setting that we may have to see) Any Doubt Reach me at :- [email protected]
