Introduction to SOA Suite 11g | SCA

Composite ●  Consists of 1 or more components ●  Is exposed as a service ●  References other services ●  Components are wired together ●  Different binding types ●  Properties can be injected

Agenda

●  Introduction to SOA Suite 11g ●  Components •  BPEL •  Spring component •  Mediator •  Business Rules •  Human Task

●  Other components ●  Conclusion

8  |  35  

Components | BPEL

Use ● Composite services ● Business processes

Alternative

● OSB ● BPMN (BPM Suite)

9  |  35  

Components | BPEL example – business process

10  |  35  

Components | BPEL example – composite service

11  |  35  

Components | BPEL best practices

Use ●  Claim check pattern ●  Simple variables, not big objects ●  Test for null in XPath ●  Testing framework ●  Error handling Common mistakes ●  Programming in BPEL

•  Translating business rules to process flow •  Calculations

●  Long running transactions ●  Using it as a data cache ●  User interface logic

12  |  35  

Components | Spring

Use ● Calculations ● Reuse libraries /

existing components

Alternative ● Deploy a bean (reference)

13  |  35  

Components | Spring example

14  |  35  

Components | Spring example

15  |  35  

Components | Spring best practices

Do ●  Use Java quality tools (Unit testing, Findbug etc) ●  Spring or external service

Common mistakes

●  Java inside BPEL -> requires restart of server ●  Java inside OSB flow -> requires restart of server ●  Flow logic in Spring component

16  |  35  

Components | Mediator

Use ● Routing ● Transformation ●  Sequencing of messages

Alternative ● BPEL for routing ● OSB ● Queuing (AQ)

17  |  35  

Components | Mediator example

18  |  35  

Components | Mediator example

19  |  35  

Components | Mediator best practices

Do ●  Think about transactions ●  Think about parallel versus serial routing rules

Common mistakes ●  Put everything in BPEL (Not use mediator) ●  Use OSB as part of your composite

20  |  35  

Components | Business rules

Use ● Rules depending on

Attributes of Object ● Edit outside of

composite

Alternative ● Case management ●  Java ● BPEL ● Mediator ● Case management (BPM)

21  |  35  

Components | Business rules example

22  |  35  

Components | Business rules example

23  |  35  

Components | Business rules best practice

Do ●  Create dictionaries ●  Test your rules, this is *NOT* trivial!

Common mistakes ●  Programming in business rules ●  Ignore them because it sounds complicated ●  Treat them as ‘regular if-then-else’

24  |  35  

Components | Human Task

Use ● Human step ● Deadline ● Approval & escalation ● Notifications

Alternative ● User interface logic ● N/A ● BPEL ● N/A

25  |  35  

Components | Human Task example

26  |  35  

Components | Human Task example

27  |  35  

Components | Human Task best practices

Use ●  Claim check pattern ●  Workflow patterns ●  Notification and escalation

Common mistakes ●  Generate the UI from the task definition ●  Small steps

28  |  35  

Agenda

●  Introduction to SOA Suite 11g ●  Components ●  Other components •  Notification Service •  Web services manager •  MDS

●  Conclusion

29  |  35  

Other components | Notification Service

30  |  35  

Components | Notification service - adapter

Use ●  In BPEL flow ●  In Human Task ● Adapter(11.1.1.8) ● Pick channel

31  |  35  

Other components | Web Services Manager

32  |  35  

Other components | Web services manager
