4 Overview! What can SCT Workflow do?! Implementing SCT Workflow! Type of people needed for:! Workflow Development! Implementation/Maintenance! Architecture! Banner Integration! Hardware and Software Requirements 4

5 What can Workflow do?

6 What can SCT Workflow do?! Worklist: One view of all tasks!! SCT Workflow can direct tasks to a shared worklist and individual worklist. Users receive one worklist!! With SCT Workflow 3.1 end users can be notified via that a new item has appeared on their list. The can contain a HTML link to the activity. 6

7 What can SCT Workflow do?! Event Dispatching! SCT Workflow can recognize events in 3 rd party systems and lookup if there is an associated workflow to start. 7

8 What can SCT Workflow do?! Automated Activities!! Workflow can execute a query in the middle of a process to fetch back more data to be used down the road.! Workflow can call scripts such as batch files or shell scripts to interact with 3 rd party applications without any user intervention. 8

9 Building a workflow

10 Background Questions! How many people have seen Workflow?! Workflow 3.x?! Does your school have PL/SQL programmers?! Does your school have java programmers? 10

11 Building a workflow! Business Process Analysis! Business process analysis takes 80% of your time.! Understand your role players and your activities. 11

12 Building a workflow! Go through a Workflow Process analysis.! Take your BPA and turn it into workflow activities.! Identify what is automated, what is interactive. What event starts the workflow? 12

13 Building a workflow! Building event in Banner! Identify the table in which to apply a trigger for which a Workflow Event will be fired upon.! Delivered with SCT Banner General is a package GOKPARM which assists in writing event data to the event tables. 13

14 Building a workflow! Building an automated activity that queries the Banner database.! Identify the data that should be retrieved. Note: Only one row of data can be retrieved to be inserted into context.! Take store procedure or query and add it to the Business Component Catalog. Once in the catalog the business analyst can incorporate the component into the workflow. 14

15 Building a workflow! Business Analyst wires together the components.! At this point the components have been created and the events are typically in place. 15

16 Building a workflow! Identifying the resources! Technical resource with Oracle database trigger experience for writing the Event Trigger.! Technical resource to write the automated activities for data retrieval should have Oracle PL/SQL experience. 16

17 Building a workflow! Identifying the resources, cont d! Business Analyst who will be the Owner of the workflow process responsible to wire the components together and maintain the workflow process when it reaches production. 17

18 Maintaining Workflow

19 System Administrator! Ideal candidate would be someone who is familiar with Oracle 9ias as well as Oracle databases.! Responsible for moving data from one system to another upon Business Analyst request.! Evaluates logs from time to time and communicates problems with the system to the workflow owners. 19

20 Architecture

21 Workflow is a J2EE application! J2EE technology and its component based model simplifies enterprise development and deployment. The J2EE platform manages the infrastructure and supports the Web services to enable development of secure, robust and interoperable business applications. Sun s website 21

30 Hardware/Software Requirements

31 Hardware Requirements! Supported Operating Systems! Solaris, HP-UX, AIX, Tru64, Windows and Linux.! Server Specs Dual Processor at least 400 mhz Memory: 2 GB of RAM Hard Disk: 1-2 GB of available space. 31

32 Software Requirements! Application Server Oracle 9ias Release 2 (9.0.3)! Java VM SDK Note: SCT Workflow 3.1 tested on 1.3.1_04 32

33 Oracle 9ias! SCT Workflow utilizes the Oracle Containers for J2EE (OC4J) component of Oracle 9ias.! Versions of 9ias that are sufficient:! Oracle 9ias J2EE and Web Cache v9.0.3! Oracle 9ias J2EE Downloads Oracle 9ias Containers for J2EE Standalone (ideal for testing) 33

34 Oracle 9ias J2EE and Web Cache v9.0.3! Pros:! Provides the Enterprise Manager to give a GUI tool to manage the 9ias instance.! Provides a more robust web server (Oracle HTTP Server)! Cons:! Resource intensive! Installation is more involved easily taking over an hour to complete. 34

35 Oracle 9ias Containers for J2EE Standalone! Pros! Installation takes 2 minutes! Requires half the resources than that of 9ias! Cons! Configurations done via scripts and manual modifications to files.! Oracle does not support SSL with the standalone version. 35

36 Oracle 9ias Things to note! SCT Workflow does not utilize the same version of 9ias that is used by SCT Banner Internet Native at the moment.! SCT Workflow can co-exist on a machine running both SCT Banner Internet Native as long as there are enough available resources to meet our requirements as well as Banner s. 36
