Trivadis Integration Architecture Blueprint
Blueprint for traditional as well as modern integration solutions
20.10.2010 Oracle Service Bus Mediator BPEL BPMN Rules Adapter Transports Oracle DB

Agenda
Case 1 – SOA based integration of ERP with external systems
Case 2 – SOA based modernization
20.10.2010 Data are always part of the game.

Case 1: Past Situation (before the project) Oracle SOA Suite in use – a practical experience report File-based
Batch based
File based
Routing logic to different external sytems hidden in PL/SQL
Non-standard interfaces to ERP
Mix of technologies
Non-standard interface Batch Hidden logic

Case 1: Used components
SOA Suite 10g components shown in red have been used
SOA Suite Oracle SOA Plattform Oracle Service Bus (OSB) BPEL Business Rule Human Workflow ESB Adapter Oracle Application Server CEP BPA Suite BPMN EPK UML Application Integration Architecture (AIA) Foundation Pack Process Integration Pack (PIP)

At the beginning, the following two options have been discussed
Case 1: Different Options considered Oracle SOA Suite in use – a practical experience report
One Process Instance per Order Line and Flow
One Process covering all the flows of
(a) an Order Line
(b) an Order Header

Case 1: Second option with Apps Adapter
Group all the events by
„ New Order“ events
All other events
„ New Order“ produces a new instance
All other events call an already existing instance
Apps Adapter as well as other adapters support this „pattern“ out of the box

E-Business Suite raises Business Events to signal changes
Middle Tier enriches the message and sends it to the right execution system instances
Communication with Execution System is via Web Services
Completion of an Order line is sent back by the execution system to ERP via the middle tier
Case 1: Big picture Oracle SOA Suite in use – a practical experience report

Case 1: Second option – Overview Oracle SOA Suite in use – a practical experience report One way operation Two way operation

Case 1: Number of Messages and BPEL instances
Order
Send Order Creation and Updates to interested systems
Order Events received (ca. 40’000 daily)
Lines delivered (ca. 5’000 daily)
Invoice Events received (ca. 200 daily)
Customer
Send Customer Create and Updates to interested systems
Events received (ca. 10’000 daily)
Events delivered (ca. 2’000 daily)
Currency Rates
Web Service to get actual currency rates
Requests (< 200 daily)

Case 2: SOA-based Integration Solution Oracle SOA Suite in use – a practical experience report

Agenda
Case 1 – SOA based integration of ERP with external systems
Case 2 – SOA based modernization
Data are always part of the game.

Case 1: Existing Solution
Existing legacy application based on Natural and Adabas DB
Old, non-relational database
Poor data quality
Clients are connecting through EAI middleware (Software AG EntireX Broker)
Proprietary solution, difficult to add new consumers

Case 2: Used components SOA Suite 11g Oracle SOA Plattform Oracle Service Bus (OSB) BPEL Business Rule Human Workflow Mediator Spring Adapter Governance Suite 11g Enterprise Repository (OER) Service Registry (OSR) WebLogic Suite CEP BPM Suite 11g BPMN BPA Suite 11g BPMN EPK UML Application Integration Architecture (AIA) Foundation Pack Process Integration Pack (PIP)

Case 2: SOA-based, stepwise modernization
Create a new data architecture in parallel based on Oracle
Bridge “old world” to new world using Oracle Service Bus
Implement new validation logic with Oracle Rules
Offer Services for new consumers
Existing solution New Datamanagement Bridge to “old world” with OSB new services/consumers

Case 2: EntireX XML Runtime & OSB Gateway Oracle SOA Suite in use – a practical experience report

Case 2: Using Split-Join on OSB for parallel invoke 20.10.2010 Split-Join pattern

Validations with Oracle Rule Engine Oracle SOA Suite in use – a practical experience report
Example: Vehicle Validation Categories
5+ different validation categories based on age and other criteria
Special rules and exceptions everywhere…  an implementation nightmare 

Data Mapping legacy format <-> canonical format Oracle SOA Suite in use – a practical experience report

Automatic Build & Deployment
Goals
Automate everything
WLS Domain creation
Schema repository creation
OSB & SOA artifacts build & deployment
soapUI integration testing
Hudson Integration
Continuous Integration 
Tools
Hudson
Maven
soapUI
Subversion
Nexus Maven Repository
