11. Slide 11 of 98 © Raastech, Inc. 2012 | All rights reserved.  Transforms complex architectures into agile integration networks by connecting, mediating, and managing interactions between services and applications  Delivers low-cost, standards-based integration for mission critical SOA environments where extreme performance and scalability are requirements

12. Slide 12 of 98 © Raastech, Inc. 2012 | All rights reserved.  A comprehensive and easy-to-use solution for policy management and security of service infrastructure  Provides visibility and control of the policies through a centralized administration interface offered by Oracle Enterprise Manager

13. Slide 13 of 98 © Raastech, Inc. 2012 | All rights reserved.  A comprehensive, hot-pluggable software suite to build, deploy and manage Service-Oriented Architectures (SOA)  Unified application development tooling and end-to-end lifecycle management

14. Slide 14 of 98 © Raastech, Inc. 2012 | All rights reserved.  Gives business executives the ability to monitor their business services and processes in the enterprise  Correlate KPIs down to the actual business process themselves  Allows the ability to change business processes quickly or to take corrective action if the business environment changes

16. Slide 16 of 98 © Raastech, Inc. 2012 | All rights reserved. High Level Flow of Use Case Web Application OSB Proxy Service Mobile Application SOA Suite Composite Database Table 1 & Table 2 BAM Reports OWSM Policy

17. Slide 17 of 98 © Raastech, Inc. 2012 | All rights reserved.  Consider using OSB as your entry (and/or exit) points  OSB is lightweight, and easily supports throttling and caching  OSB proxy services are usually exposed as web services Why OSB? Web Application OSB Proxy Service Mobile Application OSB Proxy Service OSB Proxy Service OSB Proxy Service

18. Slide 18 of 98 © Raastech, Inc. 2012 | All rights reserved. <soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <wsse:Security soap:mustUnderstand="1"> <wsse:UsernameToken> <wsse:Username>myusername</wsse:Username> <wsse:Password>mypassword</wsse:Password> </wsse:UsernameToken> </wsse:Security> </soap:Header>  Install the Oracle Service Bus OWSM Extension to provide support for WS-Security  Attach the policy “oracle/wss_username_token_service_policy”  Client must supply username and password in the SOAP header Why OWSM? OSB Proxy Service OWSM Policy

19. Slide 19 of 98 © Raastech, Inc. 2012 | All rights reserved.  Incoming payload includes:  Item Number  Quantity  Dollar Amount  Type Flag (‘M’ for mobile, ‘W’ for web)  Use BPEL for complicated flows and/or orchestration (e.g., calculate tax)  Use Mediator to route to the correct table based on the flag in the payload Why SOA Suite? SOA Suite Composite BPEL (calculate tax) Mediator (route)

20. Slide 20 of 98 © Raastech, Inc. 2012 | All rights reserved.  BAM is essentially a reporting tool  Designed to capture in-flight transactions and report on them in real-time  Does not impact performance of integration flow  In our use case, publish total dollar amounts of web orders to BAM for management reporting Why BAM? SOA Suite Composite BAM Reports

21. Slide 21 of 98 © Raastech, Inc. 2012 | All rights reserved. Bringing it all together… Web Application OSB Proxy Service Mobile Application SOA Suite Composite Database Table 1 & Table 2 BAM Reports OWSM Policy The Oracle Integration Layer

23. Slide 23 of 98 © Raastech, Inc. 2012 | All rights reserved.  Create the Order.xsd schema file  An XML schema describes the structure of an XML message Create XML Schema <?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="Order"> <xs:complexType> <xs:sequence> <xs:element name="OrderType" type="xs:string"/> <xs:element name="ItemNumber" type="xs:string"/> <xs:element name="Quantity" type="xs:positiveInteger"/> <xs:element name="Price" type="xs:decimal"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>

25. Slide 25 of 98 © Raastech, Inc. 2012 | All rights reserved.  These tables represent the backend for our order system Create the backend database tables CREATE TABLE web_orders ( item_number VARCHAR2(10), quantity NUMBER, dollar_amount NUMBER(7,2) ); CREATE TABLE mobile_orders ( item_number VARCHAR2(10), quantity NUMBER, dollar_amount NUMBER(7,2) );

31. Slide 31 of 98 © Raastech, Inc. 2012 | All rights reserved. BAM Data Object SOA Suite Composite BPEL (calculate tax) Mediator (route) WebOrders Table MobileOrders Table Price x 1.05 OrderType = ‘W’ OrderType = ‘M’

32. Slide 32 of 98 © Raastech, Inc. 2012 | All rights reserved.  A SOA composite application can consist of multiple components, such as:  BPEL component  Mediator component  Database Adapters  BAM Adapter  Open up JDeveloper 11g  Create a new SOA project Create SOA composite

35. Slide 35 of 98 © Raastech, Inc. 2012 | All rights reserved.  Adapters are used for easily referencing technologies such as databases, file systems, FTP servers, JMS, and so forth  The Database Adapter hides the underlying implementation of the connectivity of the database, so that the SOA developer can focus on building integrations  Simply drag the Database Adapter to the external references pane Create Database Adapters for each table

42. Slide 42 of 98 © Raastech, Inc. 2012 | All rights reserved.  Create a Mediator component  Mediator’s strengths are in transformation and routing  Route to the Database Adapters that we just created… …based on a filter on the ‘OrderType’ flag Create SOA Mediator component

62. Slide 62 of 98 © Raastech, Inc. 2012 | All rights reserved.  Similar to the Database Adapter, drag the BAM Adapter  Will query the BAM server and list all available data objects Create BAM Adapter

67. Slide 67 of 98 © Raastech, Inc. 2012 | All rights reserved. Deploy SOA composite  Right-click on the composite name to deploy to SOA server  URL becomes: http://soadev:8001/soa-infra/services/default/ProcessOrder/calculatetax_client_ep?WSDL

69. Slide 69 of 98 © Raastech, Inc. 2012 | All rights reserved. OWSM Policy OSB Project Proxy Service Business Service http://soadev:8001/soa-infra/...http://soadev:7001/ProcessOrderProxy/... SOA Composite

70. Slide 70 of 98 © Raastech, Inc. 2012 | All rights reserved.  The OSB server is on a separate managed server  Import the WSDL of the SOA composite  Create a Business Service (the link to the SOA composite)  Create a Proxy Service (the exposed interface)  Secure the Proxy Service with an OWSM Policy Create OSB project

82. Slide 82 of 98 © Raastech, Inc. 2012 | All rights reserved.  The exposed WSDL for the OSB Proxy Service: http://soadev:7001/ProcessOrderProxy/ProcessOrderPS?wsdl  This is the WSDL that the web/client applications will invoke Final OSB exposed WSDL

94. Slide 94 of 98 © Raastech, Inc. 2012 | All rights reserved. 4. Create the SOA composite with JDeveloper a. Open up JDeveloper 11g b. Create a SOA project c. Create 2 Database Adapter services d. Create a Mediator component i. Create a web service interface using the XSD file ii. Create 2 routing rules to the 2 database services iii. Use a filter expression on the 'OrderType' element e. Create a BPEL component i. Link the BPEL component with the Mediator component ii. Map the input of the BPEL to the input of the Mediator iii. But multiple the price by 1.05 iv. Create a BAM Adapter to the BAM Data Object v. Map the input of the BPEL to the BAM Adapter Summary

95. Slide 95 of 98 © Raastech, Inc. 2012 | All rights reserved. 5. Deploy the SOA composite a. Get the WSDL of the SOA composite 6. Create an OSB project a. Create a Business Service using this SOA WSDL b. Create a Proxy Service as the OSB interface c. Secure the Proxy Service with an OWSM Policy 7. Test using soapUI Summary

96. Slide 96 of 98 © Raastech, Inc. 2012 | All rights reserved.  Understand where each product should be aligned  There is some overlap between products  There is no one-size fits all architecture  Understand the difference between and usage of OSB, OWSM, BAM, and SOA Suite  Observe first hand a walkthrough demo:  OSB used as a passthrough, but has other benefits not demo’ed here  OWSM provides a mechanism to attach security policies to a service  BPEL used for orchestration  Mediator used for routing Take Aways

97. Slide 97 of 98 © Raastech, Inc. 2012 | All rights reserved.  All these products are provided as part of a single Oracle SOA Suite license, so take advantage of them!  You can use any combination of OSB, BPEL, or Mediator depending on your needs Final Thoughts
